Téléphones supplémentaires Affectez des numéros de téléphone à des numéros simplifiés afin de pouvoir appeler rapidement ces numéros. Numérotation simplifiée Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 9 Votre téléphone Portail d'aide en libre-service Numéros abrégés Lorsque vous composez un numéro sur votre téléphone, vous saisissez une série de chiffres. Lorsque vous configurez un numéro simplifié, ce dernier doit contenir tous les chiffres nécessaires pour passer l’appel. Par exemple, si vous devez composer le 9 pour passer un appel externe, vous devez saisir le numéro 9, puis le numéro à appeler. Vous pouvez également ajouter à ce numéro, d’autres chiffres à composer. Ces chiffres supplémentaires peuvent représenter un code d'accès à une réunion, un numéro de poste, un mot de passe de messagerie vocale, un code d’autorisation ou un code de facturation. La chaîne de numérotation peut contenir les caractères suivants : • 0 à 9 • Dièse (#) • Astérisque (*) • La virgule (,) - il s’agit du caractère de pause, qui insère un délai de 2 secondes dans la chaîne de numérotation. Vous pouvez saisir plusieurs virgules consécutives dans la chaîne. Par exemple, deux virgules (,,) représentent une pause de 4 secondes. Les règles suivantes s’appliquent aux chaînes de numérotation : • Utilisez des virgules pour séparer les parties de la chaîne de numérotation. • Un code d'autorisation doit toujours précéder un code de facturation dans la chaîne de numérotation. • Une seule virgule est nécessaire entre le code d'autorisation et le code de facturation dans la chaîne. • Une étiquette de numérotation abrégée est requise pour les numéros simplifiés qui comportent des codes d’autorisation et des chiffres supplémentaires. Avant de configurer la numérotation abrégée, composez manuellement les chiffres au moins une fois pour vous assurer que la séquence de chiffres est exacte. Votre téléphone n'enregistre pas le code d'autorisation, le code de facturation ou les chiffres supplémentaires de la numérotation abrégée dans l'historique des appels. Si vous appuyez sur Bis après vous être connecté à une destination à l'aide de la numérotation abrégée, le téléphone vousinvite à saisir manuellement les éventuels code d'autorisation, code de facturation ou chiffres supplémentaires. Exemple Pour configurer un numéro simplifié afin d’appeler une personne à un numéro de poste donné, et si un code d’autorisation et un code de facturation sont nécessaires, procédez comme suit : • Vous devez composer le 9 pour joindre une ligne externe. • Vous voulez appeler le 5556543. • Vous devez saisir le code d’autorisation 1234. • Vous devez saisir le code de facturation 9876. • Vous devez patienter pendant 4 secondes. • Lorsque l’appel est connecté, vous devez saisir le numéro de poste 56789#.

Illustration 4 : Vue en mode Ligne Différences entre les lignes téléphoniques et les appels Les termes lignes et appels sont utilisés ici de manière très précise pour expliquer comment utiliser votre téléphone. Voici une explication des différences entre ces deux termes. Lignes Chaque ligne est associée à un numéro de répertoire ou à un numéro intercom, que vos contacts peuvent utiliser pour vous appeler. Le téléphone prend en charge jusqu'à six lignes. Pour voir vos lignes téléphoniques, appuyez Téléphone pour ouvrir l’affichage des lignes. Vous disposez d'autant de lignes que de numéros de répertoire et d'icônes de lignes téléphoniques dans l'affichage des lignes. Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 18 Votre téléphone Différences entre les lignes téléphoniques et les appels Appels Chaque ligne peut prendre en charge plusieurs appels, en général quatre au maximum. Le téléphone peut prendre en charge un maximum de 24 appels connectés, mais votre administrateur système peut adapter ce nombre à vos besoins. Un seul appel peut être actif à la fois; les autres appels sont automatiquement mis en garde. Par exemple, si vous disposez de deux lignes prenant chacune en charge quatre appels, un maximum de huit appels peuvent être connectés simultanément. Seul l’un de ces appels est actif et les sept autres appels sont mis en garde. Alertes de sortie de portée Votre administrateur système peut configurer votre téléphone pour qu'il vous alerte de manière sonore (un bip) lorsque vous êtes hors de la zone de couverture du réseau sans fil. Quand vous entendez l'alerte, l'icône (pas de signal) s'affiche sur l'écran du téléphone. Lorsque que vous n'êtes plus dans une zone couverte par le réseau sans fil, vous ne pouvez pas utiliser le téléphone pour des fonctions requérant une connexion au réseau sans fil, telles que l'émission et la réception d'appels. Si votre administrateur système a activé l'alerte Hors de portée, vous pouvez, en fonction de la configuration utilisée, entendre un seul bip ou un bip toutes les 10, 30 ou 60 secondes jusqu'à ce que vous soyez de nouveau dans la zone couverte par le réseau sans fil. Pour vous raccorder de nouveau au réseau sans fil après avoir entendu l'alerte, déplacez-vous jusqu'à ce que vous voyiez de nouveau l'icône de signal sur l'écran du téléphone. Batteries du téléphone Votre téléphone contient une batterie Lithium ion. Lorsque la batterie est entièrement chargée, elle fournit les heures de service suivantes : • Jusqu’à 11.5 heures de durée de conversation (dépend du micrologiciel du téléphone et de la version du chargeur) Le tableau suivant montre les différences de durée de conversation lorsque vous utilisez : • Le nouveau 4.35 V Chargeur de bureau pour téléphone IP sans fil Cisco 8821 et Multi chargeur pour Téléphone IP sans fil Cisco 8821 • Le Chargeur de bureau pour Téléphone IPsans fil Cisco 8821-EX et Multichargeur pour Téléphone IP sans fil Cisco 8821-EX Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 19 Votre téléphone Alertes de sortie de portée Tableau 6 : Comparaison des durées de conversation Chargeur de bureau pour Téléphone IP sans fil Cisco 8821-EX et Multichargeur pour Téléphone IP sans fil Cisco 8821-EX Nouveau Chargeur de bureau pour téléphone IP sans fil Cisco 8821 et Multi chargeur pour Téléphone IP sans fil Cisco 8821 Original Chargeur de bureau pour téléphone IP sans fil Cisco 8821 et Multi chargeur pour Téléphone IP sans fil Cisco 8821 Condition Téléphone chargé dans 9,5 heures 9,5 heures 9,5 heures le chargeur, avec adaptateur mural, ou avec USB Téléphone exécutant le micrologiciel version 11.0 (4) SR3 ou antérieure Téléphone chargé dans 11,5 heures 11,5 heures 9,5 heures le chargeur, avec adaptateur mural, ou avec USB Téléphone exécutant le micrologiciel version 11.0 (4) SR3 ou supérieure Batterie de rechange 9,5 heures 11,5 heures 9,5 heures chargée dans l'emplacement de recharge • Jusqu’à 145 heures d'autonomie en mode veille. La durée de vie de la batterie dépend d’un certain nombre de facteurs, notamment : • Durée en marche : la durée de vie de la batterie est réduite lorsque le téléphone est allumé. Les appels, les messages, l'utilisation d'applications, l'utilisation de Bluetooth et des actions telles que la navigation dans le menu utilisent l'alimentation. • Mode de balayage réseau : votre téléphone peut être configuré pour analyser les points d'accès de trois manières différentes(continue, automatique, APunique).Si votre téléphone utilise les modes de balayage Continu ou Automatique, le téléphone nécessite davantage d'énergie, ce qui réduit le temps de conversation de la batterie. Une batterie de rechange chargée peut s'avérer utile pour prolonger la durée de conversation. Bluetooth et votre téléphone Vous pouvez utiliser un casque Bluetooth avec votre téléphone. Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 20 Votre téléphone Bluetooth et votre téléphone Les connexions Bluetooth sont optimales lorsque la distance vous séparant de votre téléphone est comprise entre 1 et 2 mètres, mais cette distance peut aller jusqu’à 20 mètres. La connexion Bluetooth risque de se dégrader si une barrière (un mur, une porte ou une fenêtre), un objet métallique volumineux ou d’autres périphériques électroniques sont situés entre votre téléphone et le périphérique connecté. Pour connecter un casque à votre téléphone à l'aide de Bluetooth, commencez par jumeler le casque avec votre téléphone. Vous pouvez jumeler jusqu’à 5 casques Bluetooth avec le téléphone. Une fois le casque jumelé, le téléphone s’y connecte lorsque le casque est allumé. Le dernier casque Bluetooth connecté au téléphone est le casque que le téléphone utilise par défaut. Le Téléphone IP sans fil Cisco 8821-EX n’a pas été testé ou certifié pour l’utilisation avec des accessoires dans une atmosphère potentiellement explosive.

Il suffit de ne pas mettre le ventilateur près du téléphone. Voici les choses à ne pas faire : • N’ouvrez pas le volet de la batterie lorsque le téléphone est humide. • N’utilisez pas d'air comprimé pour éliminer l’eau. • N’utilisez pas un sèche-cheveux pour sécher le téléphone. • Ne placez pas un coton-tige, de l'essuie-tout ou un chiffon dans la prise jack du casque ou à l'intérieur du compartiment de la batterie. • Ne cognez pas le téléphone sur une surface dure. • Ne chargez un téléphone humide à l'aide du câble de chargement. Vous devez attendre que le téléphone soit complètement sec. • Ne placez pas un téléphone humide dans le chargeur de bureau, ou le chargeur multiple. Vous devez attendre que le téléphone soit complètement sec. Ne soufflez pas ou n'utilisez pas d'air comprimé (par exemple, provenant de flacons d'aérosol, de buses d'air basse ou haute pression) pour nettoyer les orifices du téléphone. N'utilisez pas d'aspirateur ou un autre appareil d'aspiration pour nettoyer les orifices du téléphone. N’utilisez pas d’épingles ou d’autres objets pour nettoyer les orifices du téléphone. L'utilisation d'objets mécaniques pour nettoyer les orifices, de vide ou d'air risquerait d'endommager le téléphone et d'annuler sa garantie. Mise en garde Pour garantir que de l’eau ne pénètre pas dans le compartiment à batterie, vérifiez que ce dernier est bien fermé.

Casques Vous pouvez utiliser des casques filaires et Bluetooth avec votre téléphone. Pour obtenir des informations sur les casques pris en charge, reportez-vous au Guide des accessoires pour les téléphones IP sans fil Cisco série 882x . Bien que des tests internes soient effectués sur des casques filaires et Bluetooth sans fil de fabricants tiers pouvant être utilisés avec le Téléphones IP sans fil Cisco 8821 et 8821-EX, nous ne certifions pas et ne promouvons pas les produits des fournisseurs de casques ou de combinés. En raison des contraintes environnementales et matérielles inhérentes aux différents sites de déploiement des téléphones, il n'existe pas de solution « optimale » unique convenant à tous les environnements. Il est recommandé aux clients de tester les casques qui sont le mieux adaptés à leur environnement avant de déployer un grand nombre d'unités dans leur réseau. Le Téléphone IP sans fil Cisco 8821-EX n’a pas été testé pour l’utilisation de casques filaires et Bluetooth en environnement dangereux. Remarque Il est recommandé d'utiliser des périphériques externes de bonne qualité, par exemple des casques blindés contre les interférences produites par les signaux de fréquences radio (FR) ou audio (FA). En fonction de la qualité de ces périphériques et de leur proximité par rapport à d'autres appareils, comme lestéléphones portables et les radios bidirectionnelles, des parasites sonores peuvent toujours se produire. Pour déterminer si un casque donné convient au téléphone, vérifiez avant tout qu'il ne provoque pas de ronflement sonore. Ce ronflement peut être audible soit uniquement par votre interlocuteur, soit par votre interlocuteur et par vous, l'utilisateur du téléphone. Certainsronflements ou bourdonnements potentiels peuvent être dus à de nombreuses causes extérieures, par exemple l'éclairage électrique, les moteurs électriques ou de grands moniteurs d’ordinateur. Dans certains cas, les pièces mécaniques ou les composants électroniques de différents casques peuvent provoquer un écho sur le poste des interlocuteurs des utilisateurs des téléphones. Sujets connexes Passage d'un appel avec un casque, à la page 54 Informations importantes relatives à la sécurité des casques Pression sonore élevée : évitez d'écouter à des niveaux de volume élevés pendant de longues périodes pour éviter d'éventuels dommages auditifs. Lors du branchement de votre casque, baissez le volume de son haut-parleur avant de le placer sur votre tête. Si vous pensez à baisser le volume avant d’ôter le casque, le volume sera à un niveau faible lorsque vous rebrancherez votre casque. N’oubliez pas votre environnement. L’utilisation de votre casque risque de vous empêcher d’entendre des sons externes importants, en particulier en cas d’urgence ou dans des environnements bruyants. N’utilisez pas le casque pendant que vous conduisez. Ne laissez pas votre casque ou vos câbles dans un endroit où des Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 104 Accessoires Casques personnes ou des animaux peuvent trébucher dessus.Surveillez toujoursles enfants quise trouvent à proximité de votre casque ou de vos câbles.

Si vous branchez un casque dans le téléphone alors que vous êtes en communication, le chemin audio est automatiquement redirigé vers le casque. Casques Bluetooth Vous pouvez utiliser un casque Bluetooth avec votre téléphone. Lorsque vous utilisez un casque sans fil Bluetooth, ce dernier augmente généralement la consommation de la batterie de votre téléphone et peut entraîner une réduction de la durée de vie de la batterie. Pour qu'un casque sans fil Bluetooth fonctionne correctement, il n'est pas nécessaire de se trouver dans le champ direct du téléphone. Certains obstacles, comme les murs et les portes, ainsi que les interférences issues d'autres appareils électroniques, peuvent toutefois affecter la connexion.

DAS maximal pour ce modèle et conditions dans lesquelles il a été enregistré DAS au niveau de la tête WLAN 5 GHz 0,63 W/kg DAS près du corps WLAN 5 GHz 0,67 W/kg Ce téléphone sans fil contient un émetteur-récepteur radio. L’émetteur-récepteur radio et l’antenne ont été conçus pour respecter les exigences relatives à l’exposition humaine aux émissions RF, comme stipulé par la FCC et par certaines agences d'autres pays. Ces directives ont été développées par l’industrie selon les recommandations de l’Organisation Mondiale de la Santé (OMS). Ces normes de l’industrie incluent des marges de sécurité supplémentaires, pour garantir que l’utilisateursoit exposé à un minimum de rayonnements RF. L’émetteur-récepteur utilise un type de rayonnement non ionisant, contrairement aux rayonnements ionisants des ondes de radiographie. La norme d'exposition relative à ces appareils utilise l'unité de mesure DAS (Débit d’absorption spécifique). La limite définie par la FCC est 1,6 W/kg. Les tests concernant ce niveau d’émission sont effectués par un laboratoire indépendant qui emploie des méthodes de test et des conditions de fonctionnement révisées par la FCC et par d'autres agences. Avant sa mise en marché, le téléphone a été testé et certifié conforme aux règles de la FCC permettant de vérifier qu'il ne dépasse pas les limites définies par la FCC concernant le DAS.

Guide de l’utilisateur des téléphones IP sans fil Cisco 8821 et 8821-EX 131 Sûreté et sécurité du produit Déclaration de conformité pour le Canada DAS maximal pour ce modèle et conditions dans lesquelles il a été enregistré DAS au niveau de la tête WLAN 5 GHz 0,63 W/kg DAS près du corps WLAN 5 GHz 0,67 W/kg Déclarations de conformité pour la Nouvelle-Zélande Avertissement général relatif à Permit to Connect (PTC) L’octroi d’une licence Telepermit pour tout élément du matériel terminal indique uniquement que le fournisseur de télécommunications a accepté que l’élément soit conforme aux conditions minimales pour une connexion à son réseau. Cela ne signifie en aucun cas que le fournisseur de télécommunications cautionne le produit, ou qu’il fournit une quelconque garantie. Avant tout, cela ne garantit pas qu’un élément fonctionnera correctement, à tous égards, avec un autre élément de matériel doté d’une licence Telepermit d’une autre marque ou d’un autre modèle, ou qu’un quelconque produit est compatible avec l’ensemble des services réseau du fournisseur de télécommunications. Utilisation de réseaux IP avec PSTN Le protocole Internet (IP) introduit un retard des signaux de voix à mesure que chaque paquet de données est formulé et adressé. L’organisme Telecom Access Standards recommande aux fournisseurs, concepteurs et installateurs qui utilisent cette technologie pour les appels à destination ou en provenance du PSTN, de se référer aux exigences du Modèle E de l’UIT lors de la conception de leurs réseaux. Le but ultime est de minimiser le retard, la distorsion et les autres problèmes de transmission, en particulier pour les appels sur des réseaux cellulaires et internationaux, qui subissent déjà un retard considérable. Utilisation de la compression vocale par le biais de PSTN Les appels de réseaux cellulaires et internationaux subissent un retard considérable, partiellement dû au fait qu’ils utilisent des technologies de compression vocale. L’organisme Telecom Access Standards n’approuve que la technologie vocale G711 pour l’utilisation sur le réseau PSTN. G711 est une « technique instantanée de codage de la parole », alors que G729 et toutes ses variantes sont considérés comme étant « quasi-instantanés » et introduisent un retard supplémentaire dans le signal vocal. Annulation d'écho Normalement, l’utilisation d’annulateurs d’écho n’est pas requise dans le réseau PSTN du fournisseur de télécommunications, car les retards géographiques sont acceptables lorsque la perte en retour de l’appareil CPE est maintenue dans les limites définies par la licence Telepermit.. Cependant, les réseaux privés qui utilisent la technologie Voix sur IP (VoIP) doivent fournir l’annulation d’écho pour tous les appels vocaux. L’effet combiné du délai de conversion audio/VoIP et du délai de routage IP risque d’entraîner une durée d’annulation d’écho de 64 ms.

This document contains the following sections: • Initially Configuring a Device, page xxxiii • Using the CLI, page xxxiv • Saving Changes to a Configuration, page xliv • Additional Information, page xliv For more information about using the CLI, see the “Using the Cisco IOS Command-Line Interface” section of the Cisco IOS Configuration Fundamentals Configuration Guide. For information about the software documentation set, see the “About Cisco IOS Software Documentation” document. Initially Configuring a Device Initially configuring a device varies by platform. For information about performing an initial configuration, see the hardware installation documentation that is provided with the original packaging of the product or go to the Product/Technologies Support area of Cisco.com at http://www.cisco.com/go/techdocs. After you have performed the initial configuration and connected the device to your network, you can configure the device by using the console port or a remote access method, such as Telnet or Secure Shell (SSH), to access the CLI or by using the configuration method provided on the device, such as Security Device Manager. Using the Command-Line Interface in Cisco IOS Software Using the CLI xxxiv Cisco IOS Configuration Fundamentals Command Reference April 2010 Changing the Default Settings for a Console or AUX Port There are only two changes that you can make to a console port and an AUX port: • Change the port speed with the config-register 0x command. Changing the port speed is not recommended. The well-known default speed is 9600. • Change the behavior of the port; for example, by adding a password or changing the timeout value. Note The AUX port on the Route Processor (RP) installed in a Cisco ASR 1000 series router does not serve any useful customer purpose and should be accessed only under the advisement of a customer support representative. Using the CLI This section describes the following topics: • Understanding Command Modes, page xxxiv • Using the Interactive Help Feature, page xxxvii • Understanding Command Syntax, page xxxviii • Understanding Enable and Enable Secret Passwords, page xxxix • Using the Command History Feature, page xl • Abbreviating Commands, page xli • Using Aliases for CLI Commands, page xli • Using the no and default Forms of Commands, page xlii • Using the debug Command, page xlii • Filtering Output Using Output Modifiers, page xlii • Understanding CLI Error Messages, page xliii Understanding Command Modes The CLI command mode structure is hierarchical, and each mode supports a set of specific commands. This section describes the most common of the many modes that exist. Table 3 lists common command modes with associated CLI prompts, access and exit methods, and a brief description of how each mode is used. Using the Command-Line Interface in Cisco IOS Software Using the CLI xxxv Cisco IOS Configuration Fundamentals Command Reference April 2010 Table 3 CLI Command Modes Command Mode Access Method Prompt Exit Method Mode Usage User EXEC Log in. Router> Issue the logout or exit command. • Change terminal settings. • Perform basic tests. • Display device status. Privileged EXEC From user EXEC mode, issue the enable command. Router# Issue the disable command or the exit command to return to user EXEC mode. • Issue show and debug commands. • Copy images to the device. • Reload the device. • Manage device configuration files. • Manage device file systems. Global configuration From privileged EXEC mode, issue the configure terminal command. Router(config)# Issue the exit command or the end command to return to privileged EXEC mode. Configure the device. Interface configuration From global configuration mode, issue the interface command. Router(config-if)# Issue the exit command to return to global configuration mode or the end command to return to privileged EXEC mode. Configure individual interfaces. Line configuration From global configuration mode, issue the line vty or line console command. Router(config-line)# Issue the exit command to return to global configuration mode or the end command to return to privileged EXEC mode. Configure individual terminal lines. Using the Command-Line Interface in Cisco IOS Software Using the CLI xxxvi Cisco IOS Configuration Fundamentals Command Reference April 2010 ROM monitor From privileged EXEC mode, issue the reload command. Press the Break key during the first 60 seconds while the system is booting. rommon # > The # symbol represents the line number and increments at each prompt. Issue the continue command. • Run as the default operating mode when a valid image cannot be loaded. • Access the fall-back procedure for loading an image when the device lacks a valid image and cannot be booted. • Perform password recovery when a Ctrl-Break sequence is issued within 60 seconds of a power-on or reload event. Diagnostic (available only on Cisco ASR 1000 series routers) The router boots or enters diagnostic mode in the following scenarios. When a Cisco IOS process or processes fail, in most scenarios the router will reload. • A user-configured access policy was configured using the transport-map command, which directed the user into diagnostic mode. • The router was accessed using an RP auxiliary port. • A break signal (Ctrl-C, Ctrl-Shift-6, or the send break command) was entered, and the router was configured to enter diagnostic mode when the break signal was received. Router(diag)# If a Cisco IOS process failure is the reason for entering diagnostic mode, the failure must be resolved and the router must be rebooted to exit diagnostic mode. If the router is in diagnostic mode because of a transport-map configuration, access the router through another port or use a method that is configured to connect to the Cisco IOS CLI. If the RP auxiliary port was used to access the router, use another port for access. Accessing the router through the auxiliary port is not useful for customer purposes. • Inspect various states on the router, including the Cisco IOS state. • Replace or roll back the configuration. • Provide methods of restarting the Cisco IOS software or other processes. • Reboot hardware (such as the entire router, an RP, an ESP, a SIP, a SPA) or other hardware components. • Transfer files into or off of the router using remote access methods such as FTP, TFTP, and SCP. Table 3 CLI Command Modes (continued) Command Mode Access Method Prompt Exit Method Mode Usage Using the Command-Line Interface in Cisco IOS Software Using the CLI xxxvii Cisco IOS Configuration Fundamentals Command Reference April 2010 EXEC commands are not saved when the software reboots. Commands that you issue in a configuration mode can be saved to the startup configuration. If you save the running configuration to the startup configuration, these commands will execute when the software is rebooted. Global configuration mode is the highest level of configuration mode. From global configuration mode, you can enter a variety of other configuration modes, including protocol-specific modes. ROM monitor mode is a separate mode that is used when the software cannot load properly. If a valid software image is not found when the software boots or if the configuration file is corrupted at startup, the software might enter ROM monitor mode. Use the question symbol (?) to view the commands that you can use while the device is in ROM monitor mode. rommon 1 > ? alias set and display aliases command boot boot up an external process confreg configuration register utility cont continue executing a downloaded image context display the context of a loaded image cookie display contents of cookie PROM in hex . . . rommon 2 > The following example shows how the command prompt changes to indicate a different command mode: Router> enable Router# configure terminal Router(config)# interface ethernet 1/1 Router(config-if)# ethernet Router(config-line)# exit Router(config)# end Router# Note A keyboard alternative to the end command is Ctrl-Z. Using the Interactive Help Feature The CLI includes an interactive Help feature. Table 4 describes the purpose of the CLI interactive Help commands. Table 4 CLI Interactive Help Commands Command Purpose help Provides a brief description of the Help feature in any command mode. ? Lists all commands available for a particular command mode. partial command? Provides a list of commands that begin with the character string (no space between the command and the question mark). partial command Completes a partial command name (no space between the command and ). command ?

If nothing matches, the help list will be empty and you must backup until entering a '?' shows the available options. Two styles of help are provided: 1. Full help is available when you are ready to enter a command argument (e.g. 'show ?') and describes each possible argument. 2. Partial help is provided when an abbreviated argument is entered and you want to know what arguments match the input (e.g. 'show pr?'.) ? Router# ? Exec commands: access-enable Create a temporary access-List entry access-profile Apply user-profile to interface access-template Create a temporary access-List entry alps ALPS exec commands archive manage archive files partial command? Router(config)# zo? zone zone-pair partial command Router(config)# we webvpn command ? Router(config-if)# pppoe ? enable Enable pppoe max-sessions Maximum PPPOE sessions command keyword ? Router(config-if)# pppoe enable ? group attach a BBA group Understanding Command Syntax Command syntax is the format in which a command should be entered in the CLI. Commands include the name of the command, keywords, and arguments. Keywords are alphanumeric strings that are used literally. Arguments are placeholders for values that a user must supply. Keywords and arguments may be required or optional. Specific conventions convey information about syntax and command elements. Table 5 describes these conventions. Using the Command-Line Interface in Cisco IOS Software Using the CLI xxxix Cisco IOS Configuration Fundamentals Command Reference April 2010 The following examples show syntax conventions: Router(config)# ethernet cfm domain ? WORD domain name Router(config)# ethernet cfm domain dname ? level Router(config)# ethernet cfm domain dname level ? <0-7> maintenance level number Router(config)# ethernet cfm domain dname level 7 ? Router(config)# snmp-server file-transfer access-group 10 ? protocol protocol options Router(config)# logging host ? Hostname or A.B.C.D IP address of the syslog server ipv6 Configure IPv6 syslog server Understanding Enable and Enable Secret Passwords Some privileged EXEC commands are used for actions that impact the system, and it is recommended that you set a password for these commands to prevent unauthorized use. Two types of passwords, enable (not encrypted) and enable secret (encrypted), can be set. The following commands set these passwords and are issued in global configuration mode: • enable password • enable secret password Table 5 CLI Syntax Conventions Symbol/Text Function Notes < > (angle brackets) Indicate that the option is an argument. Sometimes arguments are displayed without angle brackets. A.B.C.D. Indicates that you must enter a dotted decimal IP address. Angle brackets (< >) are not always used to indicate that an IP address is an argument. WORD (all capital letters) Indicates that you must enter one word. Angle brackets (< >) are not always used to indicate that a WORD is an argument. LINE (all capital letters) Indicates that you must enter more than one word. Angle brackets (< >) are not always used to indicate that a LINE is an argument. (carriage return) Indicates the end of the list of available keywords and arguments, and also indicates when keywords and arguments are optional. When is the only option, you have reached the end of the branch or the end of the command if the command has only one branch. — Using the Command-Line Interface in Cisco IOS Software Using the CLI xl Cisco IOS Configuration Fundamentals Command Reference April 2010 Using an enable secret password is recommended because it is encrypted and more secure than the enable password. When you use an enable secret password, text is encrypted (unreadable) before it is written to the config.text file. When you use an enable password, the text is written as entered (readable) to the config.text file. Each type of password is case sensitive, can contain from 1 to 25 uppercase and lowercase alphanumeric characters, and can start with a numeral. Spaces are also valid password characters; for example, “two words” is a valid password. Leading spaces are ignored, but trailing spaces are recognized. Note Both password commands have numeric keywords that are single integer values. If you choose a numeral for the first character of your password followed by a space, the system will read the number as if it were the numeric keyword and not as part of your password. When both passwords are set, the enable secret password takes precedence over the enable password. To remove a password, use the no form of the commands: no enable password or no enable secret password. For more information about password recovery procedures for Cisco products, see the following: http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/ products_tech_note09186a00801746e6.shtml Using the Command History Feature The command history feature saves, in a command history buffer, the commands that you enter during a session. The default number of saved commands is 10, but the number is configurable within the range of 0 to 256. This command history feature is particularly useful for recalling long or complex commands. To change the number of commands saved in the history buffer for a terminal session, issue the terminal history size command: Router# terminal history size num A command history buffer is also available in line configuration mode with the same default and configuration options. To set the command history buffer size for a terminal session in line configuration mode, issue the history command: Router(config-line)# history [size num] To recall commands from the history buffer, use the following methods: • Press Ctrl-P or the Up Arrow key—Recalls commands beginning with the most recent command. Repeat the key sequence to recall successively older commands. • Press Ctrl-N or the Down Arrow key—Recalls the most recent commands in the history buffer after they have been recalled using Ctrl-P or the Up Arrow key. Repeat the key sequence to recall successively more recent commands. Note The arrow keys function only on ANSI-compatible terminals such as the VT100. • Issue the show history command in user EXEC or privileged EXEC mode—Lists the most recent commands that you entered. The number of commands that are displayed is determined by the setting of the terminal history size and history commands. Using the Command-Line Interface in Cisco IOS Software Using the CLI xli Cisco IOS Configuration Fundamentals Command Reference April 2010 The command history feature is enabled by default. To disable this feature for a terminal session, issue the terminal no history command in user EXEC or privileged EXEC mode or the no history command in line configuration mode. Abbreviating Commands Typing a complete command name is not always required for the command to execute. The CLI recognizes an abbreviated command when the abbreviation contains enough characters to uniquely identify the command. For example, the show version command can be abbreviated as sh ver. It cannot be abbreviated as s ver because s could mean show, set, or systat. The sh v abbreviation also is not valid because the show command has vrrp as a keyword in addition to version. (Command and keyword examples are from Cisco IOS Release 12.4(13)T.) Using Aliases for CLI Commands To save time and the repetition of entering the same command multiple times, you can use a command alias. An alias can be configured to do anything that can be done at the command line, but an alias cannot move between modes, type in passwords, or perform any interactive functions. Table 6 shows the default command aliases. To create a command alias, issue the alias command in global configuration mode. The syntax of the command is alias mode command-alias original-command. Following are some examples: • Router(config)# alias exec prt partition—privileged EXEC mode • Router(config)# alias configure sb source-bridge—global configuration mode • Router(config)# alias interface rl rate-limit—interface configuration mode To view both default and user-created aliases, issue the show alias command. For more information about the alias command, see the following: http://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_a1.html Table 6 Default Command Aliases Command Alias Original Command h help lo logout p ping s show u or un undebug w where Using the Command-Line Interface in Cisco IOS Software Using the CLI xlii Cisco IOS Configuration Fundamentals Command Reference April 2010 Using the no and default Forms of Commands Most configuration commands have a no form that is used to reset a command to its default value or to disable a feature or function. For example, the ip routing command is enabled by default. To disable this command, you would issue the no ip routing command. To re-enable IP routing, you would issue the ip routing command. Configuration commands may also have a default form, which returns the command settings to their default values. For commands that are disabled by default, using the default form has the same effect as using the no form of the command. For commands that are enabled by default and have default settings, the default form enables the command and returns the settings to their default values. To see what default commands are available on your system, enter default ? in the appropriate command mode of the command-line interface. The no form is documented in the command pages of Cisco IOS command references. The default form is generally documented in the command pages only when the default form performs a function different than that of the plain and no forms of the command. Command pages often include a “Command Default” section as well. The “Command Default” section documents the state of the configuration if the command is not used (for configuration commands) or the outcome of using the command if none of the optional keywords or arguments is specified (for EXEC commands). Using the debug Command A debug command produces extensive output that helps you troubleshoot problems in your network. These commands are available for many features and functions within Cisco IOS software. Some debug commands are debug all, debug aaa accounting, and debug mpls packets. To use debug commands during a Telnet session with a device, you must first enter the terminal monitor command. To turn off debugging completely, you must enter the undebug all command. For more information about debug commands, see the Cisco IOS Debug Command Reference: http://www.cisco.com/en/US/docs/ios/debug/command/reference/db_book.html Caution Debugging is a high priority and high CPU utilization process that can render your device unusable. Use debug commands only to troubleshoot specific problems. The best times to run debugging are during periods of low network traffic and when few users are interacting with the network. Debugging during these periods decreases the likelihood that the debug command processing overhead will affect network performance or user access or response times. Filtering Output Using Output Modifiers Many commands produce lengthy output that may use several screens to display. Using output modifiers, you can filter this output to show only the information that you want to see. Using the Command-Line Interface in Cisco IOS Software Using the CLI xliii Cisco IOS Configuration Fundamentals Command Reference April 2010 The following three output modifiers are available: • begin regular-expression—Displays the first line in which a match of the regular expression is found and all lines that follow. • include regular-expression—Displays all lines in which a match of the regular expression is found. • exclude regular-expression—Displays all lines except those in which a match of the regular expression is found. To use one of these output modifiers, type the command followed by the pipe symbol (|), the modifier, and the regular expression that you want to search for or filter. A regular expression is a case-sensitive alphanumeric pattern. It can be a single character or number, a phrase, or a more complex string. The following example illustrates how to filter output of the show interface command to display only lines that include the expression “protocol.” Router# show interface | include protocol FastEthernet0/0 is up, line protocol is up Serial4/0 is up, line protocol is up Serial4/1 is up, line protocol is up Serial4/2 is administratively down, line protocol is down Serial4/3 is administratively down, line protocol is down Understanding CLI Error Messages You may encounter some error messages while using the CLI. Table 7 shows the common CLI error messages. For more system error messages, see the Cisco IOS Release 12.4T System Message Guide. Table 7 Common CLI Error Messages Error Message Meaning How to Get Help % Ambiguous command: “show con” You did not enter enough characters for the command to be recognized. Reenter the command followed by a space and a question mark (?). The keywords that you are allowed to enter for the command appear. % Incomplete command. You did not enter all the keywords or values required by the command. Reenter the command followed by a space and a question mark (?). The keywords that you are allowed to enter for the command appear. % Invalid input detected at “^” marker. You entered the command incorrectly. The caret (^) marks the point of the error. Enter a question mark (?) to display all the commands that are available in this command mode. The keywords that you are allowed to enter for the command appear. Using the Command-Line Interface in Cisco IOS Software Saving Changes to a Configuration xliv Cisco IOS Configuration Fundamentals Command Reference April 2010 Saving Changes to a Configuration To save changes that you made to the configuration of a device, you must issue the copy running-config startup-config command or the copy system:running-config nvram:startup-config command. When you issue these commands, the configuration changes that you made are saved to the startup configuration and saved when the software reloads or power to the device is turned off or interrupted. The following example shows the syntax of the copy running-config startup-config command: Router# copy running-config startup-config Destination filename [startup-config]? You press Enter to accept the startup-config filename (the default), or type a new filename and then press Enter to accept that name. The following output is displayed indicating that the configuration was saved. Building configuration... [OK] Router# On most platforms, the configuration is saved to NVRAM. On platforms with a Class A flash file system, the configuration is saved to the location specified by the CONFIG_FILE environment variable. The CONFIG_FILE variable defaults to NVRAM.

Using the Command-Line Interface in Cisco IOS Software Additional Information xlvi Cisco IOS Configuration Fundamentals Command Reference April 2010 CF-1 Cisco IOS Configuration Fundamentals Command Reference April 2010 Introduction The Cisco IOS Configuration Fundamentals Command Reference provides command documentation associated with the following tasks: • Using the Cisco IOS Command-Line Interface (CLI) • Configuration Using Setup and AutoInstall • Configuring Operating Characteristics for Terminals • Managing Connections, Logins, Menus, and System Banners – Configure user menus and banners • Using the Cisco Web Browser User Interface (UI) – Using the HTTP server-based UI as an alternative to the CLI • Using the Cisco IOS Integrated File System (IFS) – The basics of filesystem use and Cisco IOS software’s filesystem infrastructure • Configuring Basic File Transfer Services – Copy, move, and delete files locally or across the network • Managing Configuration Files • Loading, Maintaining, and Upgrading System Images • Rebooting For further information about performing these tasks, refer to the Cisco IOS Configuration Fundamentals Configuration Guide for your release. Note Some commands previously documented in this Command Reference have been moved to other books: Commands related to system management and network monitoring can be found in the Cisco IOS Network Management Command Reference. Command reference documentation for the Cisco IOS software feature “Service Assurance Agent (SAA)” can be found in the the Cisco IOS IP SLAs Command Reference. Introduction Cisco IOS IFS Command Syntax CF-2 Cisco IOS Configuration Fundamentals Command Reference April 2010 Cisco IOS IFS Command Syntax Some commands in this book use URLs (uniform resource locators) as part of the command syntax. URLs used in the Cisco IOS Integrated File System (IFS) contain two parts: a file system or network prefix, and a file identification suffix. The following tables list URL keywords that can be used in the source-url and destination-url arguments for all commands in this book. The prefixes listed below can also be used in the filesystem arguments in this document. Table 8 lists common URL network prefixes used to indicate a device on the network. Table 9 lists the available suffix options (file indentification suffixes) for the URL prefixes used in Table 8. Table 10 lists common URL prefixes used to indicate memory locations on the system. Table 8 Network Prefixes for Cisco IFS URLs Prefix Description ftp: Specifies a File Transfer Protocol (FTP) network server. rcp: Specifies an remote copy protocol (rcp) network server. tftp: Specifies a TFTP server. Table 9 File ID Suffixes for Cisco IFS URLs Prefix Suffix Options ftp: [[//[username[:password]@]location]/directory]/filename For example: ftp://network-config (prefix://filename) ftp://user1:mypassword1@example.com/config-files rcp: rcp:[[//[username@]location]/directory]/filename tftp: tftp:[[//location]/directory]/filename Table 10 File System Prefixes for Cisco IFS URLs Prefix Description bootflash: Boot flash memory. disk0: Rotating disk media. flash: [partition-number] Flash memory. This prefix is available on all platforms. For platforms that do not have a device named flash:, the prefix flash: is aliased to slot0:. Therefore, you can use the prefix flash: to refer to the main Flash memory storage area on all platforms. flh: Flash load helper log files. null: Null destination for copies. You can copy a remote file to null to determine its size. nvram: NVRAM. This is the default location for the running-configuration file.

To make any character activate a terminal, use the no form of this command. activation-character ascii-number no activation-character Syntax Description Defaults Return (decimal 13) Command Modes Line configuration (config-line) Command History Usage Guidelines See the “ASCII Character Set and Hexadecimal Values” document for a list of ASCII characters. Note If you are using the autoselect function, set the activation character to the default, Return, and exec-character-bits to 7. If you change these defaults, the application will not recognize the activation request. Examples The following example shows how to set the activation character for the console to Delete, which is decimal character 127: Router(config)# line console Router(config-line)# activation-character 127 ascii-number Decimal representation of the activation character. Release Modification 10.0 This command was introduced. This command is supported in all Cisco IOS software Releases. Configuration Fundamentals Commands alias CF-7 Cisco IOS Configuration Fundamentals Command Reference April 2010 alias To create a command alias, use the alias command in global configuration mode. To delete all aliases in a command mode or to delete a specific alias, and to revert to the original command syntax, use the no form of this command. alias mode command-alias original-command no alias mode [command-alias] Syntax Description Defaults A set of six basic EXEC mode aliases are enabled by default. See the “Usage Guidelines” section of this command for a list of default aliases. Command Modes Global configuration Command History Usage Guidelines You can use simple words or abbreviations as command aliases. Table 11 lists the basic EXEC mode aliases that are enabled by default. The default aliases in Table 11 are predefined. These default aliases can be disabled with the no alias exec command. mode Command mode of the original and alias commands. command-alias Command alias. original-command Original command syntax. Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Table 11 Default Command Aliases Command Alias Original Command h help lo logout p ping r resume s show w where Configuration Fundamentals Commands alias CF-8 Cisco IOS Configuration Fundamentals Command Reference April 2010 Common keyword aliases (which cannot be disabled) include running-config (keyword alias for system:running-config) and startup-config (keyword alias for nvram:startup-config). See the description of the copy command for more information about these keyword aliases. Note that aliases can be configured for keywords instead of entire commands. You can create, for example, an alias for the first part of any command and still enter the additional keywords and arguments as normal. To determine the value for the mode argument, enter the command mode in which you would issue the original command (and in which you will issue the alias) and enter the ? command. The name of the command mode should appear at the top of the list of commands. For example, the second line in the following sample output shows the name of the command mode as “Interface configuration”: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface e0 Router(config-if)# ? Interface configuration commands: access-expression Build a bridge boolean access expression . . . To match the name of the command mode to the acceptable mode keyword for the alias command, issue the alias ? command. As shown in the following sample output, the keyword needed to create a command alias for the access-expression command is interface: Router(config)# alias ? accept-dialin VPDN group accept dialin configuration mode accept-dialout VPDN group accept dialout configuration mode address-family Address Family configuration mode call-discriminator Call Discriminator Configuration cascustom Cas custom configuration mode clid-group CLID group configuration mode configure Global configuration mode congestion Frame Relay congestion configuration mode controller Controller configuration mode cptone-set custom call progress tone configuration mode customer-profile customer profile configuration mode dhcp DHCP pool configuration mode dnis-group DNIS group configuration mode exec Exec mode flow-cache Flow aggregation cache config mode fr-fr FR/FR connection configuration mode interface Interface configuration mode . . . Router(config)# alias interface express access-expression When you use online help, command aliases are indicated by an asterisk (*), and displayed in the following format: *command-alias=original-command For example, the lo command alias is shown here along with other EXEC mode commands that start with “lo”: Router# lo? *lo=logout lock login logout When you use online help, aliases that contain multiple keyword elements separated by spaces are displayed in quotes, as shown here: Configuration Fundamentals Commands alias CF-9 Cisco IOS Configuration Fundamentals Command Reference April 2010 Router(config)#alias exec device-mail telnet device.cisco.com 25 Router(config)#end Router#device-mail? *device-mail=”telnet device.cisco.com 25" To list only commands and omit aliases, begin your input line with a space. In the following example, the alias td is not shown, because there is a space before the t? command line. Router(config)#alias exec td telnet device Router(config)#end Router# t? telnet terminal test tn3270 trace To circumvent command aliases, use a space before entering the command. In the following example, the command alias express is not recognized because a space is used before the command. Router(config-if)#exp? *express=access-expression Router(config-if)# express ? % Unrecognized command As with commands, you can use online help to display the arguments and keywords that can follow a command alias. In the following example, the alias td is created to represent the command telnet device. The /debug and /line switches can be added to telnet device to modify the command: Router(config)#alias exec td telnet device Router(config)#end Router#td ? /debug Enable telnet debugging mode /line Enable telnet line mode ... whois Whois port Router# telnet device You must enter the complete syntax for the command alias. Partial syntax for aliases is not accepted. In the following example, the parser does not recognize the command t as indicating the alias td: Router# t % Ambiguous command: “t” Examples In the following example, the alias fixmyrt is configured for the clear iproute 192.168.116.16 EXEC mode command: Router(config)#alias exec fixmyrt clear ip route 192.168.116.16 In the following example, the alias express is configured for the first part of the access-expression interface configuration command: Router#configure terminal Enter configuration commands, one per line.

Configuration Fundamentals Commands archive CF-11 Cisco IOS Configuration Fundamentals Command Reference April 2010 archive To enter archive configuration mode, use the archive command in global configuration mode. archive Syntax Description This command has no arguments or keywords. Command Default None Command Modes Global configuration Command History Examples The following example shows how to place the router in archive configuration mode: Router# configure terminal ! Router(config)# archive Router(config-archive)# Related Commands Release Modification 12.3(4)T This command was introduced. 12.2(25)S This command was integrated into Cisco IOS Release 12.2(25)S. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB and implemented on the Cisco 10000 series. Command Description log config Enters configuration change logger configuration mode. logging enable Enables the logging of configuration changes. maximum Sets the maximum number of archive files of the running configuration to be saved in the Cisco IOS configuration archive. path Specifies the location and filename prefix for the files in the Cisco IOS configuration archive. time-period Sets the time increment for automatically saving an archive file of the current running configuration in the Cisco IOS configuration archive. Configuration Fundamentals Commands archive config CF-12 Cisco IOS Configuration Fundamentals Command Reference April 2010 archive config To save a copy of the current running configuration to the Cisco IOS configuration archive, use the archive config command in privileged EXEC mode. archive config Syntax Description This command has no arguments or keywords. Command Modes Privileged EXEC Command History Usage Guidelines Note Before using this command, you must configure the path command in order to specify the location and filename prefix for the files in the Cisco IOS configuration archive. The Cisco IOS configuration archive is intended to provide a mechanism to store, organize, and manage an archive of Cisco IOS configuration files to enhance the configuration rollback capability provided by the configure replace command. Before this feature was introduced, you could save copies of the running configuration using the copy running-config destination-url command, storing the target file either locally or remotely. However, this method lacked any automated file management. On the other hand, the Configuration Replace and Configuration Rollback feature provides the capability to automatically save copies of the running configuration to the Cisco IOS configuration archive. These archived files serve as checkpoint configuration references and can be used by the configure replace command to revert to previous configuration states. The archive config command allows you to save Cisco IOS configurations in the configuration archive using a standard location and filename prefix that is automatically appended with an incremental version number (and optional time stamp) as each consecutive file is saved. This functionality provides a means for consistent identification of saved Cisco IOS configuration files. You can specify how many versions of the running configuration are kept in the archive. After the maximum number of files has been saved in the archive, the oldest file is automatically deleted when the next, most recent file is saved. The show archive command displays information for all configuration files saved in the Cisco IOS configuration archive. Release Modification 12.3(7)T This command was introduced. 12.2(25)S This command was integrated into Cisco IOS Release 12.2(25)S. 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(31)SB2 This command was implemented on the Cisco 10000 series. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB and implemented on the Cisco 10000 series. Configuration Fundamentals Commands archive config CF-13 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following example shows how to save the current running configuration to the Cisco IOS configuration archive using the archive config command.

Configuration Fundamentals Commands boot CF-39 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot To boot the router manually, use the boot command in ROM monitor mode. The syntax of this command varies according to the platform and ROM monitor version. boot boot file-url boot filename [tftp-ip-address] boot flash [flash-fs:][partition-number:][filename] Cisco 7000 Series, 7200 Series, 7500 Series Routers boot flash-fs:[filename] Cisco 1600 and Cisco 3600 Series Routers boot [flash-fs:][partition-number:][filename] Cisco 1800 Series, 2800 Series, and 3800 Series Routers boot usbflash0[:filename] Syntax Description file-url URL of the image to boot (for example, boot tftp://172.16.15.112/routertest). filename When used in conjunction with the ip-address argument, the filename argument is the name of the system image file to boot from a network server. The filename is case sensitive. When used in conjunction with the flash keyword, the filename argument is the name of the system image file to boot from Flash memory. On all platforms except the Cisco 1600 series, Cisco 3600 series, and Cisco 7000 family routers, the system obtains the image file from internal Flash memory. On the Cisco 1600 series, Cisco 3600 series and Cisco 7000 family routers, the flash-fs: argument specifies the Flash memory device from which to obtain the system image. (See the flash-fs: argument later in this table for valid device values.) The filename is case sensitive. Without the filename argument, the first valid file in Flash memory is loaded. If the filename is not specified, the first file in the partition or file system is used. (A USB Flash uses the first image in (compact) Flash as the boot loader and loads the image from USB Flash.) tftp-ip-address (optional) IP address of the TFTP server on which the system image resides. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. Configuration Fundamentals Commands boot CF-40 Cisco IOS Configuration Fundamentals Command Reference April 2010 Defaults For most platforms, if you enter the boot command and press Enter, the router boots from ROM by default. However, for some platforms, such as the Cisco 3600 series routers, if you enter the boot command and press Enter, the router boots the first image in Flash memory. Refer to the documentation for your platform for information about the default image. Command Modes ROM monitor Command History Usage Guidelines To determine which form of this command to use, refer to the documentation for your platform or use the CLI help (?) feature. Use this command only when your router cannot find the boot configuration information needed in NVRAM. To enter ROM monitor mode, use one of the following methods: • Enter the reload EXEC command, then press the Break key during the first 60 seconds of startup. • Set the configuration register bits 0 to 3 to zero (for example, set the configuration register to 0x0) and enter the reload command. flash Boots the router from Flash memory. Note that this keyword is required in some boot images. usbflash0 Boot the first file in USB Flash 0. If the optional filename argument is used, the router boots the specified image from USB Flash. Note This option uses the first image in (compact) Flash as the boot loader and loads the image from USB Flash. flash-fs: (Optional) Specifying the Flash file system is optional for all platforms except the Cisco 7500 series routers. Possible file systems are: • flash:—Internal Flash memory. • bootflash:—Internal Flash memory on the Cisco 7000 family. • slot0:—Flash memory card in the first PCMCIA slot on the Cisco 7000 family and Cisco 3600 series routers. • slot1:—Flash memory card in the second PCMCIA slot on the Cisco 7000 family and Cisco 3600 series routers. partition-number: (Optional) Specifies the partition number of the file system the file should be loaded from. This argument is not available on all platforms. If the partition-number is not specified, the first partition is used. Release Modification 10.3 The command was introduced. 12.3(14)T The usbflash0 keyword was added to support booting an image from an external USB Flash drive. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Configuration Fundamentals Commands boot CF-41 Cisco IOS Configuration Fundamentals Command Reference April 2010 The ROM Monitor prompt is either “>” or, for newer platforms, “rommon x>”. Enter only lowercase commands. These commands work only if there is a valid image to boot. Also, from the ROM monitor prompt, issuing a prior reset command is necessary for the boot to be consistently successful. In Cisco IOS Release 12.3(4)T, MONLIB was modified to search in media for a valid Cisco IOS image. This change prevents boot failures that result when the first file read in disk or flash is not a valid Cisco IOS image. Refer to your hardware documentation for information on correct jumper settings for your platform. Note For some platforms the flash keyword is now required. If your attempts to use the boot command are failing using the older boot flash:x:[filename] syntax, try using the boot flash flash:x:[filename] syntax. Examples In the following example, a router is manually booted from ROM: > boot F3: (ROM Monitor copyrights) In the following example, a router boots the file named routertest from a network server with the IP address 172.16.15.112 using the file-url syntax: > boot tftp://172.16.15.112/routertest F3 (ROM Monitor copyrights) The following example shows the boot flash command without the filename argument.

Configuration Fundamentals Commands boot bootldr CF-43 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot bootldr To specify the location of the boot image that ROM uses for booting, use the boot bootldr command in global configuration mode. To remove this boot image specification, use the no form of this command. boot bootldr file-url no boot bootldr Syntax Description Defaults Refer to your platform documentation for the location of the default boot image. Command Modes Global configuration (config) Command History Usage Guidelines The boot bootldr command sets the BOOTLDR variable in the current running configuration. You must specify both the Flash file system and the filename. Note When you use this global configuration command, you affect only the running configuration. You must save the variable setting to your startup configuration to place the information under ROM monitor control and to have the variable function as expected. Use the copy system:running-config nvram:startup-config command to save the variable from your running configuration to your startup configuration. Note The default length of the bootstring filename is 64 characters. Depending on the platform a longer bootstring filename can be used and supported. The no form of the command sets the BOOTLDR variable to a null string. On the Cisco 7000 family routers, a null string causes the first image file in boot Flash memory to be used as the boot image that ROM uses for booting. Use the show boot command to display the current value for the BOOTLDR variable. Examples In the following example, the internal Flash memory contains the boot image: boot bootldr bootflash:boot-image file-url URL of the boot image on a Flash file system. Release Modification 11.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Configuration Fundamentals Commands boot bootldr CF-44 Cisco IOS Configuration Fundamentals Command Reference April 2010 The following example specifies that the Flash memory card inserted in slot 0 contains the boot image: boot bootldr slot0:boot-image Related Commands Command Description copy system:running-config nvram:startup-config Copies any file from a source to a destination. show (flash file system) Displays the layout and contents of a Flash memory file system. show bootvar Displays the contents of the BOOT variable, the name of the configuration file pointed to by the CONFIG_FILE variable, the contents of the BOOTLDR variable, and the configuration register setting. Configuration Fundamentals Commands boot bootstrap CF-45 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot bootstrap To configure the filename that is used to boot a secondary bootstrap image, use the boot bootstrap command in global configuration mode. To disable booting from a secondary bootstrap image, use the no form of this command. boot bootstrap file-url no boot bootstrap file-url boot bootstrap flash [filename] no boot bootstrap flash [filename] boot bootstrap [tftp] filename [ip-address] no boot bootstrap [tftp] filename [ip-address] Syntax Description Defaults No secondary bootstrap Command Modes Global configuration Command History Usage Guidelines The boot bootstrap command causes the router to load a secondary bootstrap image from the specied URL, such as from a remote server. After the bootstrap image is loaded, the bootstrap image loads the specified system image file. See the appropriate hardware installation guide for details on the setting the configuration register and secondary bootstrap filename. Use this command when you have attempted to load a system image but have run out of memory even after compressing the system image. Secondary bootstrap images allows you to load a larger system image through a smaller secondary image. file-url URL of the bootstrap image. flash Boots the router from Flash memory. filename (Optional with flash) Name of the system image to boot from a network server or from Flash memory. If you omit the filename when booting from Flash memory, the router uses the first system image stored in Flash memory. tftp (Optional) Boots the router from a system image stored on a TFTP server. ip-address (Optional) IP address of the TFTP server on which the system image resides. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Configuration Fundamentals Commands boot bootstrap CF-46 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples In the following example, the system image file named sysimage-2 will be loaded by using a secondary bootstrap image: Router(config)# boot bootstrap bootflash:sysimage-2 Configuration Fundamentals Commands boot config CF-47 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot config To specify the device and filename of the configuration file from which the system configures itself during initialization (startup), use the boot config command in global configuration mode. To return to the default location for the configuration file, use the no form of this command. Platforms Other than Cisco 7600 Series Router boot config file-system-prefix:[directory/]filename [nvbypass] no boot config Cisco 7600 Series Router boot config device:filename [nvbypass] no boot config Syntax Description Command Default The default location for the configuration file is NVRAM (nvram:). Command Modes Global configuration (config) Command History Supported Platforms Other than Cisco 7600 Series Router This command is available only on Class A and Class B file system platforms. file-system-prefix: File system, followed by a colon (for example, nvram:, flash:, slot0:, usbflash[0-9]:, or usbtoken[0-9]:). The default is nvram:. directory/ (Optional) File system directory where the configuration file is located, followed by a forward slash (/). filename Name of the configuration file. device: Device identification, followed by a colon; see the “Usage Guidelines” section for a list of the valid values. nvbypass (Optional) Specifies that the distilled configuration is not written to nonvolatile random access memory (NVRAM). Release Modification 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(14)SX Support for this command was added for the Cisco 7600 Supervisor Engine 720. 12.2(17d)SXB Support for this command on the cisco 7600 Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 11.0 This command was introduced. 12.3(14)T Support for Class B file system platforms and the following file system prefix options were added: usbflash[0-9]: and usbtoken[0-9]:. Configuration Fundamentals Commands boot config CF-48 Cisco IOS Configuration Fundamentals Command Reference April 2010 You set the CONFIG_FILE environment variable in the current running memory when you use the boot config command. This variable specifies the configuration file used for initialization (startup). The configuration file must be an ASCII file located in either NVRAM or flash memory. Cisco 7600 Series Router The valid values for the device: argument and colon are as follows: • For systems that are configured with a Supervisor Engine 2, the valid values are bootflash:, const_nvram:, flash:, nvram:, slot0:, sup-slot0:, and sup-bootflash:. • For systems that are configured with a Supervisor Engine 720, the valid values are disk0: and disk1:. The configuration file must be an ASCII file that is located in the specified file system. The disk0: and disk1: keywords are for Class C file systems. The bootflash:, slot0:, and sup-bootflash: keywords are for Class A file systems. For Class A flash file systems, the CONFIG_FILE environment variable specifies the file system and filename of the configuration file to use for initialization (startup). You set the CONFIG_FILE environment variable in the current running memory when you use the boot config command. This variable specifies the configuration file used for initialization (startup). All Supported Platforms When you use the boot config command, you affect only the running configuration. You must save the environment variable setting to your startup configuration to place the information under ROM monitor control and to have the environment variable function as expected. Use the copy system:running-config nvram:startup-config command to save the environment variable from your running configuration to your startup configuration. The software displays an error message and does not update the CONFIG_FILE environment variable in the following situations: • You specify nvram: as the file system, and it contains only a distilled version of the configuration. (A distilled configuration is one that does not contain access lists.) • You specify a configuration file in the filename argument that does not exist or is not valid. The router uses the NVRAM configuration during initialization when the CONFIG_FILE environment variable does not exist or when it is null (such as at first-time startup). If the software detects a problem with NVRAM or the configuration it contains, the device enters setup mode. When you use the no form of this command, the router returns to using the default NVRAM configuration file as the startup configuration. You can display the contents of the BOOT, BOOTLDR, and the CONFIG_FILE environment variables using the show bootvar command. This command displays the settings for these variables as they exist in the startup configuration and in the running configuration if a running configuration setting differs from a startup configuration setting. When the boot config command is used, the distilled configuration is written into NVRAM and the system configuration is written into the file specified by the boot config command. If the distilled configuration exceeds the size of NVRAM, the system configuration gets truncated. Use the nvbypass keyword to prevent the system configuration from being truncated when the distilled configuration is larger than the size of NVRAM. Configuration Fundamentals Commands boot config CF-49 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following example shows how to set the configuration file that is located in internal flash memory to configure itself during initialization. The third line copies the specification to the startup configuration, ensuring that this specification will take effect upon the next reload. Router(config)# boot config flash:router-config Router(config)# end Router# copy system:running-config nvram:startup-config The following example instructs a Cisco 7500 series router to use the configuration file named router-config located on the flash memory card inserted in the second Personal Computer Memory Card Industry Association (PCMCIA) slot of the Route Switch Processor (RSP) card during initialization. The third line copies the specification to the startup configuration, ensuring that this specification will take effect upon the next reload. Router (config)# boot config slot1:router-config Router (config)# end Router# copy system:running-config nvram:startup-config Related Commands Command Description copy system:running-config nvram:startup-config Saves the environment variable from the running configuration to the startup configuration. show bootvar Displays the contents of the BOOT environment variable, the name of the configuration file pointed to by the CONFIG_FILE environment variable, the contents of the BOOTLDR environment variable, and the configuration register setting. Configuration Fundamentals Commands boot host CF-50 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot host To specify the host-specific configuration file to be used at the next system startup, use the boot host command in global configuration mode. To restore the host configuration filename to the default, use the no form of this command. boot host remote-url no boot host remote-url Syntax Description Defaults If you do not specify a filename using this command, the router uses its configured host name to request a configuration file from a remote server. To form the configuration filename, the router converts its name to all lowercase letters, removes all domain information, and appends -confg or -config. Command Modes Global configuration Command History Usage Guidelines This command instructs the system to “Boot using host-specific configuration file x,” where x is the filename specified in the remote-url argument. In other words, this command specifies the remote location and filename of the host-specific configuration file to be used at the next system startup, as well as the protocol to be used to obtain the file. Before using the boot host command, use the service config global configuration command to enable the loading of the specified configuration file at reboot time. Without this command, the router ignores the boot host command and uses the configuration information in NVRAM. If the configuration information in NVRAM is invalid or missing, the service config command is enabled automatically. The network server will attempt to load two configuration files from remote hosts. The first is the network configuration file containing commands that apply to all network servers on a network. Use the boot network command to identify the network configuration file. The second is the host configuration file containing commands that apply to one network server in particular. Use the boot host command to identify the host configuration file. remote-url Location of the configuration file. Use the following syntax: • ftp:[[[//[username[:password]@]location]/directory]/filename] • rcp:[[[//[username@]location]/directory]/filename] • tftp:[[[//location]/directory]/filename] Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Configuration Fundamentals Commands boot host CF-51 Cisco IOS Configuration Fundamentals Command Reference April 2010 Note Usually, the service config command is used in conjunction with the boot host or boot network command. You must enter the service config command to enable the router to automatically configure the system from the file specified by the boot host or boot network command. With IOS software versions 12.3(2)T , 12.3(1)B, and later, you no longer have to specify the service config command for the boot host or boot network command to be active. If you specify both the no service config command and the boot host command, the router attempts to find the specified host configuration file. The service config command can also be used without the boot host or boot network command. If you do not specify host or network configuration filenames, the router uses the default configuration files. The default network configuration file is network-confg. The default host configuration file is host-confg, where host is the hostname of the router. If the Cisco IOS software cannot resolve its hostname, the default host configuration file is router-confg. Loading a Configuration File Using rcp The rcp software requires that a client send the remote username on each rcp request to the network server. If the server has a directory structure (such as UNIX systems), the rcp implementation searches for the configuration files starting in the directory associated with the remote username. When you load a configuration file from a server using rcp, the Cisco IOS software sends the first valid username in the following list: 1. The username specified in the file-URL, if a username is specified. 2. The username set by the ip rcmd remote-username command, if the command is configured. 3. The router host name. Note An account for the username must be defined on the destination server. If the network administrator of the destination server did not establish an account for the username, this command will not execute successfully. Loading a Configuration File Using FTP The FTP protocol requires a client to send a remote username and password on each FTP request to a server. The username and password must be associated with an account on the FTP server. If the server has a directory structure, the configuration file or image copied from the directory is associated with the username on the server. Refer to the documentation for your FTP server for more details. When you load a configuration file from a server using FTP, the Cisco IOS software sends the first valid username in the following list: 1. The username specified in the boot host command, if a username is specified. 2. The username set by the ip ftp username command, if the command is configured. 3. Anonymous. The router sends the first valid password in the following list: 1. The password specified in the boot host command, if a password is specified. 2. The password set by the ip ftp password command, if the command is configured. Configuration Fundamentals Commands boot host CF-52 Cisco IOS Configuration Fundamentals Command Reference April 2010 3. The router forms a password username@routername.domain. The variable username is the username associated with the current session, routername is the configured host name, and domain is the domain of the router. Examples The following example sets the host filename to wilma-confg at address 192.168.7.19: Router(config)# boot host tftp://192.168.7.19/usr/local/tftpdir/wilma-confg Router(config)# service config Related Commands Command Description boot network Specifies the remote location and filename of the network configuration file to be used at the next system boot (startup). service config Enables autoloading of configuration files from a network server. Configuration Fundamentals Commands boot network CF-53 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot network To change the default name of the network configuration file from which to load configuration commands, use the boot network command in global configuration mode. To restore the network configuration filename to the default, use the no form of this command. boot network remote-url no boot network remote-url Syntax Description Defaults The default filename is network-config. Command Modes Global configuration Command History Usage Guidelines This command instructs the system to “Boot using network configuration file x,” where x is the filename specified in the remote-url argument. This command specifies the remote location and filename of the network configuration file to be used at the next system startup, as well as the protocol to be used to obtain the file. When booting from a network server, routers ignore routing information, static IP routes, and bridging information. As a result, intermediate routers are responsible for handling FTP, rcp, or TFTP requests. Before booting from a network server, verify that a server is available by using the ping command. Use the service config command to enable the loading of the specified configuration file at reboot time. Without this command, the router ignores the boot network command and uses the configuration information in NVRAM. If the configuration information in NVRAM is invalid or missing, the service config command is enabled automatically. The network server will attempt to load two configuration files from remote hosts. The first is the network configuration file containing commands that apply to all network servers on a network. Use the boot network command to identify the network configuration file. The second is the host configuration file containing commands that apply to one network server in particular. Use the boot host command to identify the host configuration file. remote-url Location of the configuration file. Use the following syntax: • ftp:[[[//[username[:password]@]location]/directory]/filename] • rcp:[[[//[username@]location]/directory]/filename] • tftp:[[[//location]/directory]/filename] Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Configuration Fundamentals Commands boot network CF-54 Cisco IOS Configuration Fundamentals Command Reference April 2010 Note Usually, the service config command is used in conjunction with the boot host or boot network command. You must enter the service config command to enable the router to automatically configure the system from the file specified by the boot host or boot network command. With IOS software versions 12.3(2)T , 12.3(1)B, and later, you no longer have to specify the service config command for the boot host or boot network command to be active. If you specify both the no service config command and the boot host command, the router attempts to find the specified host configuration file. The service config command can also be used without the boot host or boot network command. If you do not specify host or network configuration filenames, the router uses the default configuration files. The default network configuration file is network-confg. The default host configuration file is host-confg, where host is the hostname of the router. If the Cisco IOS software cannot resolve its hostname, the default host configuration file is router-confg. Loading a Configuration File Using rcp The rcp software requires that a client send the remote username on each rcp request to the network server. If the server has a directory structure (such as UNIX systems), the rcp implementation searches for the configuration files starting in the directory associated with the remote username. When you load a configuration file from a server using rcp, the Cisco IOS software sends the first valid username in the following list: 1. The username specified in the file-URL, if a username is specified. 2. The username set by the ip rcmd remote-username command, if the command is configured. 3. The router host name. Note An account for the username must be defined on the destination server. If the network administrator of the destination server did not establish an account for the username, this command will not execute successfully. Loading a Configuration File Using FTP The FTP protocol requires a client to send a remote username and password on each FTP request to a server. The username and password must be associated with an account on the FTP server. If the server has a directory structure, the configuration file or image copied from the directory associated with the username on the server. Refer to the documentation for your FTP server for more details. When you load a configuration file from a server using FTP, the Cisco IOS software sends the first valid username in the following list: 1. The username specified in the boot network command, if a username is specified. 2. The username set by the ip ftp username command, if the command is configured. 3. Anonymous. The router sends the first valid password in the following list: 1. The password specified in the boot network command, if a password is specified. 2. The password set by the ip ftp password command, if the command is configured. Configuration Fundamentals Commands boot network CF-55 Cisco IOS Configuration Fundamentals Command Reference April 2010 3. The router forms a password username@routername.domain. The variable username is the username associated with the current session, routername is the configured host name, and domain is the domain of the router. Examples The following example changes the network configuration filename to bridge_9.1 and uses the default broadcast address: Router(config)# boot network tftp:bridge_9.1 Router(config)# service config The following example changes the network configuration filename to bridge_9.1, specifies that rcp is to be used as the transport mechanism, and gives 172.16.1.111 as the IP address of the server on which the network configuration file resides: Router(config)# service config Router(config)# boot network rcp://172.16.1.111/bridge_9.1 Related Commands Command Description boot host Specifies the remote location and filename of the host-specific configuration file to be used at the next system boot (startup). service config Enables autoloading of configuration files from a remote host. Configuration Fundamentals Commands boot system CF-56 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot system To specify the system image that the router loads at startup, use one of the following boot system command in global configuration mode. To remove the startup system image specification, use the no form of this command. Loading System Image from a URL or a TFTP File boot system {file-url | filename} no boot system {file-url | filename} Booting from a System Image in Internal Flash boot system flash [flash-fs:] [partition-number:] [filename] no boot system flash [flash-fs:] [partition-number:] [filename] Booting from a MOP Server boot system mop filename [mac-address] [interface] no boot system mop filename [mac-address] [interface] Booting from ROM boot system rom no boot system rom Booting a System Image from a Network, TFTP, or FTP Server boot system {rcp | tftp | ftp} filename [ip-address] no boot system {rcp | tftp | ftp} filename [ip-address] Syntax Description file-url The URL of the system image to load at system startup. filename The TFTP filename of the system image to load at system startup. flash On all platforms except the Cisco 1600 series, Cisco 3600 series, and Cisco 7000 family routers, this keyword boots the router from internal flash memory. If you omit all arguments that follow this keyword, the system searches internal Flash for the first bootable image. On the Cisco 1600 series, Cisco 3600 series, and Cisco 7000 family routers, this keyword boots the router from the flash system specified by the flash-fs: argument. On the Cisco 1600 series and Cisco 3600 series routers, if you omit all optional arguments, the router searches internal flash memory for the first bootable image. On the Cisco 7000 family routers, when you omit all arguments that follow this keyword, the system searches the Personal Computer Memory Card Industry Association (PCMCIA) slot 0 for the first bootable image. Configuration Fundamentals Commands boot system CF-57 Cisco IOS Configuration Fundamentals Command Reference April 2010 flash-fs: (Optional) Flash file system containing the system image to load at startup. The colon is required. Valid file systems are as follows: • flash:—Internal flash memory on the Cisco 1600 series and Cisco 3600 series routers. For the Cisco 1600 series and Cisco 3600 series routers, this file system is the default if you do not specify a file system. This is the only valid file system for the Cisco 1600 series. • bootflash:—Internal flash memory in the Cisco 7000 family. • slot0:—First PCMCIA slot on the Cisco 3600 series and Cisco 7000 family routers. For the Cisco 7000 family routers, this file system is the default if you do not specify a file system. • slot1:—Flash memory card in the second PCMCIA slot on the Cisco 3600 series and Cisco 7000 family routers. On the Cisco 2600 series routers, a file system should be specified. Otherwise, the router may attempt to load the Cisco IOS software twice with unexpected results. partition-number: (Optional) Number of the flash memory partition that contains the system image to boot, specified by the optional filename argument. If you do not specify a filename, the router loads the first valid file in the specified partition of flash memory. This argument is valid only on routers that can be partitioned. filename (Optional when used with the boot system flash command) Name of the system image to load at startup. This argument is case sensitive. If you do not specify a value for the filename argument, the router loads the first valid file in the following: • The specified flash file system • The specified partition of flash memory • The default flash file system if you also omitted the flash-fs: argument mop Boots the router from a system image stored on a DECNET Maintenance Operations Protocol (MOP) server. Do not use this keyword with the Cisco 3600 series or Cisco 7000 family routers. mac-address (Optional) MAC address of the MOP server containing the specified system image file. If you do not include the MAC address argument, the router sends a broadcast message to all MOP boot servers. The first MOP server to indicate that it has the specified file is the server from which the router gets the boot image. interface (Optional) Interface the router uses to send out MOP requests to the MOP server. The interface options are async, dialer, ethernet, serial, and tunnel. If you do not specify the interface argument, the router sends a request out on all interfaces that have MOP enabled. The interface that receives the first response is the interface the router uses to load the software. rom Boots the router from ROM. Do not use this keyword with the Cisco 3600 series or the Cisco 7000 family routers. rcp Boots the router from a system image stored on a network server using rcp. tftp Boots the router from a system image stored on a TFTP server. Configuration Fundamentals Commands boot system CF-58 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Default If you configure the router to boot from a network server but do not specify a system image file with the boot system command, the router uses the configuration register settings to determine the default system image filename. The router forms the default boot filename by starting with the word cisco and then appending the octal equivalent of the boot field number in the configuration register, followed by a hyphen (-) and the processor type name (cisconn-cpu). Refer to the appropriate hardware installation guide for details on the configuration register and default filename. See also the config-register or confreg command. Command Modes Global configuration Command History Usage Guidelines For this command to work, the config-register command must be set properly. Enter several boot system commands to provide a fail-safe method for booting your router. The router stores and executes the boot system commands in the order in which you enter them in the configuration file. If you enter multiple boot commands of the same type—for example, if you enter two commands that instruct the router to boot from different network servers—then the router tries them in the order in which they appear in the configuration file. If a boot system command entry in the list specifies an invalid device, the router omits that entry. Use the boot system rom command to specify use of the ROM system image as a backup to other boot system commands in the configuration. For some platforms, the boot image must be loaded before the system image is loaded. However, on many platforms, the boot image is loaded only if the router is booting from a network server or if the flash file system is not specified. If the file system is specified, the router will boot faster because it need not load the boot image first. This section contains the following topics: • Changing the List of Boot System Commands • Booting Compressed Images • Understanding rcp • Understanding TFTP • Understanding FTP ftp Boots the router from a system image stored on an FTP server. ip-address (Optional) IP address of the server containing the system image file. If omitted, this value defaults to the IP broadcast address of 255.255.255.255. Release Modification 10.0 This command was introduced. 12.2(14)SX Support for this command was added for the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(31)SB2 This command was integrated into Cisco IOS Release 12.2(31)SB. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. Configuration Fundamentals Commands boot system CF-59 Cisco IOS Configuration Fundamentals Command Reference April 2010 • Stopping Booting and Entering ROM Monitor Mode • Cisco 1600 Series, Cisco 3600 Series, Cisco 7000 Family, and Cisco 7600 Series Router Notes Changing the List of Boot System Commands To remove a single entry from the bootable image list, use the no form of the command with an argument. For example, to remove the entry that specifies a bootable image on a flash memory card inserted in the second slot, use the no boot system flash slot1:[filename] command. All other entries in the list remain. To eliminate all entries in the bootable image list, use the no boot system command. At this point, you can redefine the list of bootable images using the previous boot system commands. Remember to save your changes to your startup configuration by issuing the copy system:running-config nvram:startup-config command. Each time you write a new software image to flash memory, you must delete the existing filename in the configuration file with the no boot system flash filename command. Then add a new line in the configuration file with the boot system flash filename command. Note If you want to rearrange the order of the entries in the configuration file, you must first issue the no boot system command and then redefine the list. Booting Compressed Images You can boot the router from a compressed image on a network server. When a network server boots software, both the image being booted and the running image must be able to fit into memory. Use compressed images to ensure that enough memory is available to boot the router. You can compress a software image on any UNIX platform using the compress command. Refer to your UNIX platform’s documentation for the exact usage of the compress command. (You can also uncompress data with the UNIX uncompress command.) Understanding rcp The rcp requires that a client send the remote username in an rcp request to a server. When the router executes the boot system rcp command, the Cisco IOS software sends the hostname as both the remote and local usernames by default. Before the rcp can execute properly, an account must be defined on the network server for the remote username configured on the router. If the server has a directory structure, the rcp software searches for the system image to boot from the remote server relative to the directory of the remote username. By default, the router software sends the hostname as the remote username. You can override the default remote username by using the ip rcmd remote-username command. For example, if the system image resides in the home directory of a user on the server, you can specify that user’s name as the remote username. Understanding TFTP You need a TFTP server running to retrieve the router image from the host. Understanding FTP You need an FTP server running to retrieve the router image from the host. You also need an account on the server or anonymous file access to the server. Configuration Fundamentals Commands boot system CF-60 Cisco IOS Configuration Fundamentals Command Reference April 2010 Stopping Booting and Entering ROM Monitor Mode During the first 60 seconds of startup, you can force the router to stop booting by pressing the Break key. The router will enter ROM monitor mode, where you can change the configuration register value or boot the router manually. Cisco 1600 Series, Cisco 3600 Series, Cisco 7000 Family, and Cisco 7600 Series Router Notes For the Cisco 3600 series and Cisco 7000 family, the boot system command modifies the BOOT variable in the running configuration. The BOOT variable specifies a list of bootable images on various devices. Note When you use the boot system command on the Cisco 1600 series, Cisco 3600 series, Cisco 7000 family, and Cisco 7600 series, you affect only the running configuration. You must save the BOOT variable settings to your startup configuration to place the information under ROM monitor control and to have the variable function as expected. Use the copy system:running-config nvram:startup-config privileged EXEC command to save the variable from your running configuration to your startup configuration. To display the contents of the BOOT variable, use the show bootvar EXEC command. Examples The following example illustrates a configuration that specifies two possible internetwork locations for a system image, with the ROM software being used as a backup: Router(config)# boot system tftp://192.168.7.24/cs3-rx.90-1 Router(config)# boot system tftp://192.168.7.19/cs3-rx.83-2 Router(config)# boot system rom The following example boots the system boot relocatable image file named igs-bpx-l from partition 2 of the flash device: Router(config)# boot system flash:2:igs-bpx-l The following example instructs the router to boot from an image located on the flash memory card inserted in slot 0: Router(config)# boot system slot0:new-config The following example specifies the file named new-ios-image as the system image for a Cisco 3600 series router to load at startup. This file is located in the fourth partition of the flash memory card in slot 0. Router(config)# boot system slot0:4:dirt/images/new-ios-image This example boots from the image file named c1600-y-l in partition 2 of flash memory of a Cisco 1600 series router: Router(config)# boot system flash:2:c1600-y-l Related Commands Command Description boot Boots the router manually. config-register Changes the configuration register settings.

Command Description Configuration Fundamentals Commands boot-end-marker CF-62 Cisco IOS Configuration Fundamentals Command Reference April 2010 boot-end-marker The boot-start-marker and boot-end-marker flags, which can be seen in Cisco IOS software configuration files, are not CLI commands. These markers are written to configuration files automatically to flag the beginning and end of the boot commands (boot statements). By flagging boot statements, these markers allow the router to more reliably load Cisco IOS images during bootup. A boot statement is one or more lines in a configuration file that tells the router which software image to load after a powercycling (reboot). The boot-start-marker and boot-end-marker flags will appear around any boot commands, including: • boot bootstrap • boot config • boot host • boot network • boot system Note, however, that these markers will always appear in the output of the show running-config or more system:running-config commands, regardless of whether any actual boot commands have been entered. This means that no boot commands will appear between the markers if no boot commands have been entered, or if all boot commands have been removed from the configuration, as shown in the “Examples” section. The boot-start-marker and boot-end-marker flags cannot be removed or modified using the CLI. These markers are written to the startup configuration file whenever a copy running-config startup-config command is issued. These flags were also introduced to circumvent errors in the configuration file, such as a leading space before a boot command (such as those sometimes introduced by manually edited configuration files), or the use of text strings that include the word “boot” in banners or other user-specified text. If the “boot start-marker” flag is not found in the configuration file, the system will use the traditional method to identify the boot commands. However, if you are manually creating configuration files, or copying from older Cisco IOS software releases, the addition of these markers is recommended. Command History Examples In the following example, a boot command is entered, and the boot-start-marker and boot-end-marker flags are shown in the context of the startup configuration file: Router# configure terminal Enter configuration commands, one per line.

For platforms that do not have a physical device named flash:, the keyword flash: is aliased to the default Flash device. For the Supervisor Engine, the initial default file system is disk0:. If you do not specify a directory on a file system, the default is the root directory on that file system. Command Modes User EXEC Privileged EXEC Command History Usage Guidelines The valid values for filesystem: are as follows: • For systems that are configured with a Supervisor Engine 2, valid values are bootflash:, const_nvram:, disk0:, flash:, nvram:, slot0:, sup-slot0:, and sup-bootflash:. • For systems that are configured with a Supervisor Engine 720, valid values are disk0: and disk1:. For all EXEC commands that have an optional filesystem argument, the system uses the file system specified by the cd command when you omit the optional filesystem argument. For example, the dir command, which displays a list of files on a file system, contains an optional filesystem argument. When you omit this argument, the system lists the files on the file system specified by the cd command. If you do not specify a directory on a file system, the default is the root directory on that file system. Examples In the following example, the cd command is used to set the default file system to the Flash memory card inserted in slot 0: Router# pwd filesystem: (Optional) The URL or alias of the directory or file systems followed by a colon. directory (Optional) Name of the directory. Release Modification 11.0 This command was introduced. 12.2(14)SX This command was integrated into Cisco IOS Release 12.2(14)SX, and support was introduced on the Supervisor Engine 720. 12.2(17d)SXB Support was added for the Supervisor Engine 2. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. cd CF-67 Cisco IOS Configuration Fundamentals Command Reference April 2010 bootflash:/ Router# cd slot0: Router# pwd slot0:/ Cisco 7600 Series This example sets the default file system to the Flash PC card that is inserted in disk 0: Router# cd disk0: Router# pwd disk0:/ Related Commands Command Description copy Copies any file from a source to a destination. delete Deletes a file on a Flash memory device. dir Displays a list of files on a file system. mkdir disk0: Creates a new directory in a Flash file system. pwd Displays the current setting of the cd command. show file systems Lists available file systems and their alias prefix names. undelete Recovers a file marked “deleted” on a Class A or Class B Flash file system. clear archive log config CF-68 Cisco IOS Configuration Fundamentals Command Reference April 2010 clear archive log config To purge the configuration logging database entries, use the clear archive log config command in privileged EXEC mode. clear archive log config [force | persistent] Syntax Description Command Default If this command is not used, the database entries accumulate in the archive log. Command Modes Privileged EXEC (#) Command History Usage Guidelines When the clear archive log config command is entered, only the entries in the configuration logging database file are deleted.

Command Description show vlan counters Displays the software-cached counter values. clock CF-84 Cisco IOS Configuration Fundamentals Command Reference April 2010 clock To configure the port clocking mode for the 1000BASE-T transceivers, use the clock command in interface configuration mode. To return to the default settings,use the no form of this command. clock {auto | active [prefer] | passive [prefer]} no clock Syntax Description Defaults auto Command Modes Interface configuration Command History Usage Guidelines This command is supported on the 1000BASE-T transceivers only. If the clock mode of the near end of a link does not match the clock mode of the far end, the line protocol does not come up. The active and passive clock status is determined during the auto negotiation process before the transmission link is established. The clock command supports the following configurations: • auto—Auto negotiates with the far end of the link but preference is given to the active-clock switch. • active—Uses a local clock to determine transmitter-operation timing. • passive—Recovers the clock from the received signal and uses the recovered clock to determine transmitter-operation timing. • active prefer—Auto negotiates with the far end of the link but preference is given to the active-clock switch. • passive prefer—Auto negotiates with the far end of the link but preference is given to the passive-clock switch. Enter the show running-config interface command to display the current clock mode. Enter the show interfaces command to display the clock mode that is negotiated by the firmware. auto Enables the automatic-clock configuration. active Enables the active operation. prefer (Optional) Negotiates the specified mode with the far end of the link. passive Enables the passive operation.

To disable the restart of the system clock from the last known system clock value, use the no form of this command. clock initialize nvram no clock initialize nvram Syntax Description This command has no arguments or keywords. Command Default By default, the system clock is set to restart from the last known system clock value for platforms that have no hardware calendar. Command Modes Global configuration (config) Command History Usage Guidelines For platforms that have hardware calendars, the clock initialize nvram command is not available. When the no form of the command is configured, the system clock gets initialized to default standard values. The default values can be either 1MAR1993 or 1MAR2002. Examples The following example shows how to set the system clock to restart from the last known system clock value: Router(config)# clock initialize nvram Release Modification 12.3(4)T This command was introduced. config-register CF-87 Cisco IOS Configuration Fundamentals Command Reference April 2010 config-register To change the configuration register settings, use the config-register command in global configuration mode. config-register value Syntax Description Command Default Refer to the documentation for your platform for the default configuration register value. For many newer platforms, the default is 0x2102, which causes the router to boot from Flash memory and the Break key to be ignored. Command Modes Global configuration Command History Usage Guidelines This command applies only to platforms that use a software configuration register. The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field determines if the router boots manually, from ROM, or from Flash or the network. To change the boot field value and leave all other bits set to their default values, follow these guidelines: • If you set the configuration register boot field value to 0x0, you must boot the operating system manually with the boot command. • If you set the configuration register boot field value to 0x1, the router boots using the default ROM software. • If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the boot field value to form a default boot filename for booting from a network server. For more information about the configuration register bit settings and default filenames, refer to the appropriate router hardware installation guide. Note In a virtual switch application, If you have configured your config-register with a value that would skip file parsing during the bootup process, your change to either a standalone or virtual switch will not take place until you reconfigure your config-register. The config-register must be allowed to parse files in order to ensure the conversion from either a standalone or virtual switch. value Hexadecimal or decimal value that represents the 16-bit configuration register value that you want to use the next time the router is restarted. The value range is from 0x0 to 0xFFFF (0 to 65535 in decimal).

To disable the single-user access (configuration locking) feature, use the no form of this command. Syntax for Releases 12.3T/12.2S: configuration mode exclusive {auto | manual} no configuration mode exclusive {auto | manual} Syntax for Release 12.0(31)S, 12.2(33)SRA, and Later Releases: configuration mode exclusive {auto | manual} [expire seconds] [lock-show] [interleave] [terminate] [config_wait seconds] [retry_wait seconds] Syntax Description auto Automatically limits configuration to single-user mode. manual Allows you to manually limit the configuration file to single-user mode. expire seconds (Optional) Specifies the number of seconds in which the configuration lock is released after the user stops making configuration changes. lock-show (Optional) Gives priority to configuration commands being executed from the exclusive configuration session, and prevents the execution of show commands. interleave (Optional) Allows show commands from sessions that are not holding the configuration lock to be executed when the user in the session holding the configuration lock is not making configuration changes. Note If you entered lock-show, you should enter this keyword. terminate (Optional) Causes the configuration command executed from the exclusive configuration session to terminate show and clear commands being executed in other sessions. config_wait seconds (Optional) Amount of time, in seconds, that a configuration command entered by a user in single user mode waits for show commands entered by other users to finish being executed. If the show command is still being executed when the timer expires and if the terminate option is set, the configuration command terminates the show command. If the configuration command completes execution before the specified number of seconds, the show command begins execution. retry_wait seconds (Optional) Specifies the amount of time, in seconds, that show and clear EXEC commands will wait for a configuration command entered by a user in exclusive configuration mode to complete execution. If the configuration command is still being executed when the specified amount of time has passed, the EXEC commands generate an error message and are terminated. If execution of the configuration command is completed before the specified number of seconds, the EXEC commands are executed. configuration mode exclusive CF-90 Cisco IOS Configuration Fundamentals Command Reference April 2010 Defaults Single-user mode is disabled. Command Modes Global configuration Command History Usage Guidelines The configuration mode exclusive command enables the exclusive configuration lock feature. The exclusive configuration lock allows single-user access to configuration modes using single-user configuration mode. While the device configuration is locked, no other users can enter configuration commands. Users accessing the device using the state-full, session-based transports (telnet, SSH) are able to enter single-user configuration mode. The user enters single-user configuration mode by acquiring the exclusive configuration lock using the configure terminal lock privileged EXEC mode command. The configuration lock is released when the user exits configuration mode by using the end or exit command, or by pressing Ctrl-Z. While a user is in single-user configuration mode, no other users can configure the device. Users accessing CLI options through stateless protocols (that is, the HTTP web-based user interface) cannot access single-user configuration mode. (However, an API allows the stateless transports to lock the configuration mode, complete its operations, and release the lock.) Examples The following example shows how to configure the configuration file for single-user autoconfiguration mode by using the configuration mode exclusive auto command. Use the configuration terminal command to enter global configuration mode and lock the configuration mode exclusively. After the Cisco IOS configuration mode is locked exclusively, you can verify this configuration by entering the show configuration lock command.

Command Modes Privileged EXEC Command History Usage Guidelines On all platforms except Class A Flash file system platforms, this command executes the commands located in the configuration file in NVRAM (the “startup configuration file”). On Class A Flash file system platforms, if you specify the configure memory command, the router executes the commands pointed to by the CONFIG_FILE environment variable. The CONFIG_FILE environment variable specifies the location of the configuration file that the router uses to configure itself during initialization. The file can be located in NVRAM or any of the Flash file systems supported by the platform. When the CONFIG_FILE environment variable specifies NVRAM, the router executes the NVRAM configuration only if it is an entire configuration, not a distilled version. A distilled configuration is one that does not contain access lists. To view the contents of the CONFIG_FILE environment variable, use the show bootvar EXEC command. To modify the CONFIG_FILE environment variable, use the boot config command and then save your changes by issuing the copy system:running-config nvram:startup-config command. Examples In the following example, a router is configured from the configuration file in the memory location pointed to by the CONFIG_FILE environment variable: Router# configure memory Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

Command Description configure network CF-99 Cisco IOS Configuration Fundamentals Command Reference April 2010 configure network The configure network command was replaced by the copy {rcp | tftp} running-config command in Cisco IOS Release 11.0. To maintain backward compatibility, the configure network command continues to function in Cisco IOS Release 12.2(11)T for most systems, but support for this command may be removed in a future release. The copy {rcp | tftp} running-config command was replaced by the copy {ftp: | rcp: | tftp:}[filename] system:running-config command in Cisco IOS Release 12.1. The copy {ftp: | rcp: | tftp:}[filename] system:running-config command specifies that a configuration file should be copied from a FTP, rcp, or TFTP source to the running configuration. See the description of the copy command in this chapter for more information. configure overwrite-network CF-100 Cisco IOS Configuration Fundamentals Command Reference April 2010 configure overwrite-network The configure overwrite-network has been replaced by the copy {ftp-url | rcp-url | tftp-url} nvram:startup-config command. See the description of the copy command in the “Cisco IOS File System Commands” chapter for more information. configure replace CF-101 Cisco IOS Configuration Fundamentals Command Reference April 2010 configure replace To replace the current running configuration with a saved Cisco IOS configuration file, use the configure replace command in privileged EXEC mode. configure replace target-url [nolock] [list] [force] [ignorecase] [revert trigger [error] [timer minutes] | time minutes] Syntax Description Command Modes Privileged EXEC (#) Command History target-url URL (accessible by the Cisco IOS file system) of the saved Cisco IOS configuration file that is to replace the current running configuration. nolock (Optional) Disables the locking of the running configuration file that prevents other users from changing the running configuration during a configuration replace operation. list (Optional) Displays a list of the command lines applied by the Cisco IOS software parser during each pass of the configuration replace operation. The total number of passes performed is also displayed. force (Optional) Replaces the current running configuration file with the specified saved Cisco IOS configuration file without prompting you for confirmation. ignorecase (Optional) Instructs the configuration to ignore the case of the configuration confirmation. revert trigger (Optional) Sets the triggers for reverting to the original configuration. • error—Reverts to the original configuration upon error. • timer minutes—Reverts to the original configuration if the specified time elapses. time minutes (Optional) Time (in minutes) within which you must enter the configure confirm command to confirm replacement of the current running configuration file. If the configure confirm command is not entered within the specified time limit, the configuration replace operation is automatically reversed (in other words, the current running configuration file is restored to the configuration state that existed prior to entering the configure replace command). Release Modification 12.3(7)T This command was introduced. 12.2(25)S The nolock keyword was added. 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(31)SB2 This command was implemented on the Cisco 10000 series. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. 12.2(33)SXI This command was integrated into Cisco IOS Release 12.2(33)SXI. 12.4(20)T The revert and trigger keywords were added. configure replace CF-102 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines When configuring more than one keyword option, the following rules apply: • The list keyword must be entered before the force and time keywords. • The force keyword must be entered before the time keyword. If the current running configuration is replaced with a saved Cisco IOS configuration file that contains commands unaccepted by the Cisco IOS software parser, an error message is displayed listing the commands that were unaccepted. The total number of passes performed in the configuration replace operation is also displayed. Note In Cisco IOS Release 12.2(25)S, a locking feature for the configuration replace operation was introduced. When the configure replace command is enabled, the Cisco IOS running configuration file is locked by default for the duration of the configuration replace operation. This locking mechanism prevents other users from changing the running configuration while the replace operation is taking place, which might otherwise cause the replace operation to terminate unsuccessfully. You can disable the locking of the running configuration using the configure replace nolock command. The running configuration lock is automatically cleared at the end of the configuration replace operation. It is not expected that you should need to clear the lock manually during the replace operation, but as a protection against any unforeseen circumstances, you can manually clear the lock using the clear configuration lock command. You can also display any locks that may be currently applied to the running configuration using the show configuration lock command. Examples This section contains the following examples: • Replacing the Current Running Configuration with a Saved Cisco IOS Configuration File • Reverting to the Startup Configuration File • Performing a Configuration Replace Operation with the configure confirm Command • Performing a Configuration Rollback Operation Replacing the Current Running Configuration with a Saved Cisco IOS Configuration File The following example shows how to replace the current running configuration with a saved Cisco IOS configuration file named disk0:myconfig. Note that the configure replace command interactively prompts you to confirm the operation. Router# configure replace disk0:myconfig This will apply all necessary additions and deletions to replace the current running configuration with the contents of the specified configuration file, which is assumed to be a complete configuration, not a partial configuration.

Router# configure replace nvram:startup-config force Total number of passes: 1 Rollback Done Performing a Configuration Replace Operation with the configure confirm Command The following example shows the use of the configure replace command with the time seconds keyword and argument. You must enter the configure confirm command within the specified time limit to confirm replacement of the current running configuration file. If the configure confirm command is not entered within the specified time limit, the configuration replace operation is automatically reversed (in other words, the current running configuration file is restored to the configuration state that existed prior to entering the configure replace command). Router# configure replace nvram:startup-config time 120 This will apply all necessary additions and deletions to replace the current running configuration with the contents of the specified configuration file, which is assumed to be a complete configuration, not a partial configuration. Enter Y if you are sure you want to proceed. ? [no]: Y Total number of passes: 1 Rollback Done Router# configure confirm Performing a Configuration Rollback Operation The following example shows how to make changes to the current running configuration and then roll back the changes. As part of the configuration rollback operation, you must save the current running configuration before making changes to the file. In this example, the archive config command is used to save the current running configuration. Note that the generated output of the configure replace command indicates that only one pass was performed to complete the rollback operation. configure replace CF-104 Cisco IOS Configuration Fundamentals Command Reference April 2010 Note The path command must be configured before using the archive config command. You first save the current running configuration in the configuration archive as follows: Router# archive config You then enter configuration changes as shown in the following example: Router# configure terminal Router(config)# user netops2 password rain Router(config)# user netops3 password snow Router(config)# exit After making changes to the running configuration file, you might want to roll back these changes and revert to the configuration that existed before the changes were made. The show archive command is used to verify the version of the configuration to be used as a target file. The configure replace command is then used to revert to the target configuration file as shown in the following example: Router# show archive There are currently 1 archive configurations saved. The next archive file will be named disk0:myconfig-2 Archive # Name 0 1 disk0:myconfig-1 <- Most Recent 2 3 4 5 6 7 8 9 10 Router# configure replace disk0:myconfig-1 Total number of passes: 1 Rollback Done Related Commands Command Description archive config Saves a copy of the current running configuration to the Cisco IOS configuration archive. configure confirm Confirms replacement of the current running configuration with a saved Cisco IOS configuration file. maximum Sets the maximum number of archive files of the running configuration to be saved in the Cisco IOS configuration archive. path Specifies the location and filename prefix for the files in the Cisco IOS configuration archive. show archive Displays information about the files saved in the Cisco IOS configuration archive. time-period Sets the time increment for automatically saving an archive file of the current running configuration in the Cisco IOS configuration archive. configure revert CF-105 Cisco IOS Configuration Fundamentals Command Reference April 2010 configure revert To cancel the timed rollback and trigger the rollback immediately, or to reset parameters for the timed rollback, use the configure revert command in privileged EXEC mode. configure revert {now | timer {minutes | idle minutes}} Syntax Description Command Modes Privileged EXEC (#) Command History Usage Guidelines In order to use the configure revert command to configure a timed rollback, the Configuration Archive functionality must be enable first. The Configuration Archive APIs are used to store the current configuration before applying any changes or rolling back to the previous configuration. In case of multi-user environments, only the user who enabled the timed rollback functionality will have the permission to perform the following operations: • Confirm the configuration change • Reset the timer • Cancel the timer and trigger rollback immediately Examples The following example shows how to cancel the timed rollback and revert to the saved configuration immediately: Rourter(config)# archive Router(config-archive)# path disk0:abc Router# configure revert now now Cancels the timed rollback and reverts immediately. timer Resets the confirmation timer. minutes Time in minutes (1-120). idle minutes Idle time in minutes (1-120) for which to wait before rollback.

Note that commands in this mode are written to the running configuration file as soon as you enter them (using the Enter key/Carriage Return). After you enter the configure terminal command, the system prompt changes from # to (config)#, indicating that the router is in global configuration mode. To leave global configuration mode and return to privileged EXEC mode, type exit or press Ctrl-Z. To view the changes to the configuration you have made, use the more system:running-config command or show running-config command in user EXEC or privileged EXEC mode. lock (Optional) Locks the running configuration into exclusive configuration mode for the duration of your configuration session.

Command Modes ROM monitor Command History Usage Guidelines Not all versions in the ROM monitor support this command. Refer to your platform documentation for more information on ROM monitor mode. If you use this command without specifying the configuration register value, the router prompts for each bit of the configuration register. The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field determines if the router boots manually, from ROM, or from Flash or the network. To change the boot field value and leave all other bits set to their default values, follow these guidelines: • If you set the configuration register boot field value to 0x0, you must boot the operating system manually with the boot command. • If you set the configuration register boot field value to 0x1, the router boots using the default ROM software. • If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the boot field value to form a default boot filename for booting from a network server. For more information about the configuration register bit settings and default filenames, refer to the appropriate router hardware installation guide. Examples In the following example, the configuration register is set to boot the system image from Flash memory: confreg 0x210F In the following example, no configuration value is entered, so the system prompts for each bit in the register: value (Optional) Hexadecimal value that represents the 16-bit configuration register value that you want to use the next time the router is restarted. The value range is from 0x0 to 0xFFFF.

Defaults No default behavior or values. Command Modes ROM monitor Command History Usage Guidelines Use this command to return to EXEC mode from ROM monitor mode, to use the system image instead of reloading. On older platforms, the angle bracket (< >) indicates that the router is in ROM monitor mode. On newer platforms, rommon number> is the default ROM monitor prompt. Typically, the router is in ROM monitor mode when you manually load a system image or perform diagnostic tests. Otherwise, the router will most likely never be in this mode. Caution While in ROM monitor mode, the Cisco IOS system software is suspended until you issue either a reset or the continue command. Examples In the following example, the continue command switches the router from ROM monitor to EXEC mode: > continue Router# Related Commands Release Modification 11.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description boot Boots the router manually. copy CF-112 Cisco IOS Configuration Fundamentals Command Reference April 2010 copy To copy any file from a source to a destination, use the copy command in privileged EXEC or diagnostic mode. copy [/erase] [/verify | /noverify] source-url destination-url Syntax Description The exact format of the source and destination URLs varies according to the file or directory location. You may enter either an alias keyword for a particular file or a filename that follows the standard Cisco IOS file system syntax (filesystem:[/filepath][/filename]). Table 18 shows two keyword shortcuts to URLs. /erase (Optional) Erases the destination file system before copying. Note This option is typically provided on platforms with limited memory to allow for an easy way to clear local flash memory space. /verify (Optional) Verifies the digital signature of the destination file. If verification fails, the file is deleted from the destination file system. This option applies to Cisco IOS software image files only. /noverify (Optional) If the file being copied is an image file, this keyword disables the automatic image verification that occurs after an image is copied. Note This keyword is often issued if the file verify auto command is enabled, which automatically verifies the digital signature of all images that are copied. source-url The location URL (or alias) of the source file or directory to be copied. The source can be either local or remote, depending upon whether the file is being downloaded or uploaded. destination-url The destination URL (or alias) of the copied file or directory. The destination can be either local or remote, depending upon whether the file is being downloaded or uploaded. Table 18 Common Keyword Aliases to URLs Keyword Source or Destination running-config (Optional) Keyword alias for the system:running-config URL. The system:running-config keyword represents the current running configuration file. This keyword does not work in more and show file EXEC command syntaxes. startup-config (Optional) Keyword alias for the nvram:startup-config URL. The nvram:startup-config keyword represents the configuration file used during initialization (startup). This file is contained in NVRAM for all platforms except the Cisco 7000 family, which uses the CONFIG_FILE environment variable to specify the startup configuration. The Cisco 4500 series cannot use the copy running-config startup-config command. This keyword does not work in more and show file EXEC command syntaxes. copy CF-113 Cisco IOS Configuration Fundamentals Command Reference April 2010 The following tables list URL prefix keywords by file system type. The available file systems will vary by platform. If you do not specify a URL prefix keyword, the router looks for a file in the current directory. Table 19 lists URL prefix keywords for Special (opaque) file systems. Table 20 lists them for remote file systems, and Table 21 lists them for local writable storage. Table 19 URL Prefix Keywords for Special File Systems Keyword Source or Destination cns: Source URL for Cisco Networking Services files. flh: Source URL for flash load helper log files. logging Source URL which copies messages from the logging buffer to a file. modem: Destination URL for loading modem firmware on to supported networking devices. null: Null destination for copies or files. You can copy a remote file to null to determine its size. nvram: Router NVRAM. You can copy the startup configuration to NVRAM or from NVRAM. obfl: Source or destination URL for Onboard Failure Logging files. stby-nvram: Router NVRAM on the standby hardware. You can copy the startup configuration to NVRAM or from NVRAM. stby-obfl: Source or destination URL for Onboard Failure Logging files on the standby hardware. system: Source or destination URL for system memory, which includes the running configuration. tar: Source URL for the archive file system. tmpsys: Source or destination URL for the temporary system files. xmodem: Source or destination for a file from a network machine that uses the Xmodem protocol. ymodem: Source or destination for a file from a network machine that uses the Ymodem protocol. Table 20 URL Prefix Keywords for Remote File Systems Keyword Source or Destination ftp: Source or destination URL for FTP network server. The syntax for this alias is as follows: ftp:[[[//username [:password]@]location]/directory]/filename. http:// Source or destination URL for an HTTP server (also called a web server). The syntax for this alias is as follows: http://[[username:password]@]{hostname | host-ip}[/filepath]/filename https:// Source or destination URL for a Secure HTTP (HTTPS) server. HTTPS uses Secure Socket Layer (SSL) encryption. The syntax for this alias is as follows: https://[[username:password]@]{hostname | host-ip}[/filepath]/filename copy CF-114 Cisco IOS Configuration Fundamentals Command Reference April 2010 rcp: Source or destination URL for a remote copy protocol (rcp) network server. The syntax for this alias is as follows: rcp:[[[//username@]location]/directory]/filename scp: Source or destination URL for a network server that supports Secure Shell (SSH) and accepts copies of files using the secure copy protocol (scp). The syntax for this alias is as follows: scp://username@location[/directory][/filename] tftp: Source or destination URL for a TFTP network server. The syntax for this alias is as follows: tftp:[[//location]/directory]/filename. Table 21 URL Prefix Keywords for Local Writable Storage File Systems Alias Source or Destination bootflash: Source or destination URL for boot flash memory. disk0: and disk1: Source or destination URL of disk-based media. flash: Source or destination URL for flash memory. This alias is available on all platforms. For platforms that lack a flash: device, note that flash: is aliased to slot0:, allowing you to refer to the main flash memory storage area on all platforms. harddisk: Source or destination URL of the active harddisk file system. slavebootflash: Source or destination URL for internal flash memory on the slave RSP card of a router configured for HSA. slaveram: NVRAM on a slave RSP card of a router configured for HSA. slaveslot0: Source or destination URL of the first Personal Computer Memory Card International Association (PCMCIA) card on a slave RSP card of a router configured for HSA. slaveslot1: Source or destination URL of the second PCMCIA slot on a slave RSP card of a router configured for HSA. slot0: Source or destination URL of the first PCMCIA flash memory card. slot1: Source or destination URL of the second PCMCIA flash memory card. stby-bootflash: Source or destination URL for boot flash memory in standby RP. stby-harddisk: Source or destination URL for the standby harddisk. stby-usb[0-1]: Source or destination URL for the Universal Serial Bus (USB) flash drive that has been plugged into the router and is located on the standby RP. usb[0-1]: Source or destination URL for the Universal Serial Bus (USB) flash drive that has been plugged into the router and is located on the active RP. usbflash[0-9]: Source or destination URL for the Universal Serial Bus (USB) flash drive that has been plugged into the router. usbtoken[0-9]: Source or destination URL for the USB eToken that has been plugged into the router. Table 20 URL Prefix Keywords for Remote File Systems Keyword Source or Destination copy CF-115 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Modes Privileged EXEC (#) Diagnostic (diag) Command History Usage Guidelines The fundamental function of the copy command is to allow you to copy a file (such as a system image or configuration file) from one location to another location. The source and destination for the file is specified using a Cisco IOS File System URL, which allows you to specify any supported local or remote file location. The file system being used (such as a local memory source, or a remote server) dictates the syntax used in the command. You can enter on the command line all necessary source- and destination-URL information and the username and password to use, or you can enter the copy command and have the router prompt you for any missing information. For local file systems, two commonly used aliases exist for the system:running-config and nvram:startup-config files; these aliases are running-config and startup-config, respectively. Timesaver Aliases are used to reduce the amount of typing you need to perform. For example, it is easier to type copy run start (the abbreviated form of the copy running-config startup-config command) than it is to type copy system:r nvram:s (the abbreviated form of the copy system:running-config nvram:startup-config command). These aliases also allow you to continue using some of the common commands used in previous versions of Cisco IOS software. Release Modification 11.3T This command was introduced. 12.3(2)T • The http:// and https:// keywords were added as supported remote source locations (file system URL prefixes) for files. • This command was enhanced to support copying files to servers that support SSH and the scp. 12.2(14)S This command was integrated into Cisco IOS Release 12.2(14)S. 12.2(18)S The /verify and /noverify keywords were added. 12.0(26)S The /verify and /noverify keywords were integrated into Cisco IOS Release 12.0(26)S. 12.3(4)T The /verify and /noverify keywords were integrated into Cisco IOS Release 12.3(4)T. 12.3(7)T The http:// and https:// keywords were enhanced to support file uploads. 12.3(14)T The usbflash[0-9]: and usbtoken[0-9]: keywords were added to support USB storage. 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. 12.2(25)SG This command was integrated into Cisco IOS Release 12.2(25)SG. 12.4(11)T This command was integrated into the Cisco 7200VXR NPE-G2 platform. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH.

The colon is required after the file system URL prefix keywords (such as flash). In some cases, file system prefixes that did not require colons in earlier software releases are allowed for backwards compatibility, but use of the colon is recommended. In the URL syntax for ftp:, http:, https:, rcp:, scp: and tftp:, the location is either an IP address or a host name. The filename is specified relative to the directory used for file transfers.

Specifically, you cannot copy: • From a running configuration to a running configuration • From a startup configuration to a startup configuration • From a device to the same device (for example, the copy flash: flash: command is invalid) Understanding Character Descriptions Table 22 describes the characters that you may see during processing of the copy command. copy CF-117 Cisco IOS Configuration Fundamentals Command Reference April 2010 Understanding Partitions You cannot copy an image or configuration file to a flash partition from which you are currently running. For example, if partition 1 is running the current system image, copy the configuration file or image to partition 2. Otherwise, the copy operation will fail. You can identify the available flash partitions by entering the show file system EXEC command. Using rcp The rcp requires a client to send a remote username upon each rcp request to a server. When you copy a configuration file or image between the router and a server using rcp, the Cisco IOS software sends the first valid username it encounters in the following sequence: 1. The remote username specified in the copy command, if a username is specified. 2. The username set by the ip rcmd remote-username global configuration command, if the command is configured. 3. The remote username associated with the current tty (terminal) process. For example, if the user is connected to the router through Telnet and was authenticated through the username command, the router software sends the Telnet username as the remote username. 4. The router host name. For the rcp copy request to process, an account must be defined on the network server for the remote username. If the network administrator of the destination server did not establish an account for the remote username, this command will not run. If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the remote username on the server. For example, if the system image resides in the home directory of a user on the server, specify that username as the remote username. If you are writing to the server, the rcp server must be properly configured to accept the rcp write request from the user on the router. For UNIX systems, add an entry to the .rhosts file for the remote user on the rcp server. Suppose the router contains the following configuration lines: hostname Rtr1 ip rcmd remote-username User0 Table 22 copy Character Descriptions Character Description ! For network transfers, an exclamation point indicates that the copy process is taking place. Each exclamation point indicates the successful transfer of ten packets (512 bytes each). . For network transfers, a period indicates that the copy process timed out. Many periods in a row typically mean that the copy process may fail. O For network transfers, an uppercase O indicates that a packet was received out of order and the copy process may fail. e For flash erasures, a lowercase e indicates that a device is being erased. E An uppercase E indicates an error. The copy process may fail. V A series of uppercase Vs indicates the progress during the verification of the image checksum. copy CF-118 Cisco IOS Configuration Fundamentals Command Reference April 2010 If the router IP address translates to Router1.company.com, then the .rhosts file for User0 on the rcp server should contain the following line: Router1.company.com Rtr1 Refer to the documentation for your rcp server for more details. If you are using a personal computer as a file server, the computer must support the remote shell protocol (rsh). Using FTP The FTP protocol requires a client to send a username and password with each FTP request to a remote FTP server. Use the ip ftp username and ip ftp password global configuration commands to specify a default username and password for all copy operations to or from an FTP server. Include the username in the copy command syntax if you want to specify a username for that copy operation only. When you copy a file from the router to a server using FTP, the Cisco IOS software sends the first valid username that it encounters in the following sequence: 1. The username specified in the copy command, if a username is specified. 2. The username set by the ip ftp username command, if the command is configured. 3. Anonymous. The router sends the first valid password in the following list: 1. The password specified in the copy command, if a password is specified. 2. The password set by the ip ftp password command, if the command is configured. 3. The router forms a password username@routername.domain. The variable username is the username associated with the current session, routername is the configured host name, and domain is the domain of the router. The username and password must be associated with an account on the FTP server. If you are writing to the server, the FTP server must be properly configured to accept the FTP write request from the user on the router. If the server has a directory structure, the configuration file or image is written to or copied from the directory associated with the username on the server. For example, if the system image resides in the home directory of a user on the server, specify that username as the remote username. Refer to the documentation for your FTP server for details on setting up the server. Using HTTP or HTTPS Copying a file to or from a remote HTTP or HTTPS server, to or from a local file system, is performed using the embedded Secure HTTP client that is integrated in Cisco IOS software. The HTTP client is enabled by default. Downloading files from a remote HTTP or HTTPS server is performed using the HTTP client integrated in Cisco IOS software. If a username and password are not specified in the copy command syntax, the system uses the default HTTP client username and password, if configured. When you copy a file from a remote HTTP or HTTPS server, the Cisco IOS software sends the first valid username that it encounters in the following sequence: 1. The username specified in the copy command, if a username is specified. 2. The username set by the ip http client username command, if the command is configured. 3. Anonymous. copy CF-119 Cisco IOS Configuration Fundamentals Command Reference April 2010 The router sends the first valid password in the following list: 1. The password specified in the copy command, if a password is specified. 2. The password set by the ip http client password command, if the command is configured. 3. The router forms the password username@routername.domain. The variable username is the username associated with the current session, routername is the configured host name, and domain is the domain of the router. Storing Images on Servers Use the copy flash: destination-url command (for example, copy flash: tftp:) to copy a system image or boot image from flash memory to a network server. You can use the copy of the image as a backup copy. Also, you can also use the image backup file to verify that the image in flash memory is the same as that in the original file. Copying from a Server to Flash Memory Use the copy destination-url flash: command (for example, copy tftp: flash:) to copy an image from a server to flash memory. On Class B file system platforms, the system provides an option to erase existing flash memory before writing onto it. Note Verify the image in flash memory before booting the image. Verifying Images When copying a new image to your router, you should confirm that the image was not corrupted during the copy process. You can verify the integrity of the image in any of the following ways: • Depending on the destination file system type, a checksum for the image file may be displayed when the copy command completes. You can verify this checksum by comparing it to the checksum value provided for your image file on Cisco.com. Caution If the checksum values do not match, do not reboot the router. Instead, reissue the copy command and compare the checksums again. If the checksum is repeatedly wrong, copy the original image back into flash memory before you reboot the router from flash memory. If you have a corrupted image in flash memory and try to boot from flash memory, the router will start the system image contained in ROM (assuming booting from a network server is not configured). If ROM does not contain a fully functional system image, the router might not function and will need to be reconfigured through a direct console port connection. • Use the /verify keyword. • Enable automatic image verification by default by issuing the file verify auto command. This command will automatically check the integrity of each file that is copied via the copy command (without specifying the /verify option) to the router unless the /noverify keyword is specified. • Use the UNIX 'diff' command. This method can also be applied to file types other than Cisco IOS images. If you suspect that a file is corrupted, copy the suspect file and the original file to a UNIX server. (The file names may need to be modified if you try to save the files in the same directory.) Then run the UNIX 'diff' command on the two files. If there is no difference, then the file has not been corrupted. copy CF-120 Cisco IOS Configuration Fundamentals Command Reference April 2010 Copying a Configuration File from a Server to the Running Configuration Use the copy {ftp: | rcp: | scp: | tftp:} running-config command to load a configuration file from a network server to the running configuration of the router. (Note that running-config is the alias for the system:running-config keyword.) The configuration will be added to the running configuration as if the commands were typed in the command-line interface (CLI). Thus, the resulting configuration file will be a combination of the previous running configuration and the loaded configuration file, with the loaded configuration file having precedence. You can copy either a host configuration file or a network configuration file. Accept the default value of host to copy and load a host configuration file containing commands that apply to one network server in particular. Enter network to copy and load a network configuration file containing commands that apply to all network servers on a network. Copying a Configuration File from a Server to the Startup Configuration Use the copy {ftp: | rcp: | scp: | tftp:} nvram:startup-config command to copy a configuration file from a network server to the router startup configuration. These commands replace the startup configuration file with the copied configuration file. Storing the Running or Startup Configuration on a Server Use the copy system:running-config {ftp: | rcp: | scp: | tftp:} command to copy the current configuration file to a network server using FTP, rcp, scp, or TFTP. Use the copy nvram:startup-config {ftp: | rcp: | scp: | tftp:} command to copy the startup configuration file to a network server. The configuration file copy can serve as a backup copy. Saving the Running Configuration to the Startup Configuration Use the copy system:running-config nvram:startup-config command to copy the running configuration to the startup configuration. Note Some specific commands might not get saved to NVRAM. You will need to enter these commands again if you reboot the machine. These commands are noted in the documentation. We recommend that you keep a listing of these settings so you can quickly reconfigure your router after rebooting. If you issue the copy system:running-config nvram:startup-config command from a bootstrap system image, a warning will instruct you to indicate whether you want your previous NVRAM configuration to be overwritten and configuration commands to be lost. This warning does not appear if NVRAM contains an invalid configuration or if the previous configuration in NVRAM was generated by a bootstrap system image. On all platforms except Class A file system platforms, the copy system:running-config nvram:startup-config command copies the currently running configuration to NVRAM. On the Class A flash file system platforms, the copy system:running-config nvram:startup-config command copies the currently running configuration to the location specified by the CONFIG_FILE environment variable. This variable specifies the device and configuration file used for initialization. When the CONFIG_FILE environment variable points to NVRAM or when this variable does not exist (such as at first-time startup), the software writes the current configuration to NVRAM. If the current configuration is too large for NVRAM, the software displays a message and stops executing the command. copy CF-121 Cisco IOS Configuration Fundamentals Command Reference April 2010 When the CONFIG_FILE environment variable specifies a valid device other than nvram: (that is, flash:, bootflash:, slot0:, or slot1:), the software writes the current configuration to the specified device and filename, and stores a distilled version of the configuration in NVRAM. A distilled version is one that does not contain access list information. If NVRAM already contains a copy of a complete configuration, the router prompts you to confirm the copy. Using CONFIG_FILE, BOOT, and BOOTLDR Environment Variables For the Class A flash file system platforms, specifications are as follows: • The CONFIG_FILE environment variable specifies the configuration file used during router initialization. • The BOOT environment variable specifies a list of bootable images on various devices. • The BOOTLDR environment variable specifies the flash device and filename containing the rxboot image that ROM uses for booting. • Cisco 3600 routers do not use a dedicated boot helper image (rxboot), which many other routers use to help with the boot process. Instead, the BOOTLDR ROM monitor environment variable identifies the flash memory device and filename that are used as the boot helper; the default is the first system image in flash memory. To view the contents of environment variables, use the show bootvar EXEC command. To modify the CONFIG_FILE environment variable, use the boot config global configuration command. To modify the BOOTLDR environment variable, use the boot bootldr global configuration command. To modify the BOOT environment variable, use the boot system global configuration command. To save your modifications, use the copy system:running-config nvram:startup-config command. When the destination of a copy command is specified by the CONFIG_FILE or BOOTLDR environment variable, the router prompts you for confirmation before proceeding with the copy. When the destination is the only valid image in the BOOT environment variable, the router also prompts you for confirmation before proceeding with the copy. Using the Copy Command with the Dual RSP Feature The Dual RSP feature allows you to install two Route Switch Processor (RSP) cards in a single router on the Cisco 7507 and Cisco 7513 platforms. On a Cisco 7507 or Cisco 7513 router configured for Dual RSPs, if you copy a file to nvram:startup-configuration with automatic synchronization disabled, the system prompts whether you also want to copy the file to the slave startup configuration. The default answer is yes. If automatic synchronization is enabled, the system automatically copies the file to the slave startup configuration each time you use a copy command with nvram:startup-configuration as the destination. Using the copy command with the ASR1000 Series Routers The copy command is available in both privileged EXEC and diagnostic mode on the Cisco ASR1000 series routers. Because the copy command is available in diagnostic mode, it can be used to copy all types of files between directories and remote locations even in the event of an IOS failure. Examples The following examples illustrate uses of the copy command: • Verifying the Integrity of the Image Before It Is Copied Example, page 122 • Copying an Image from a Server to Flash Memory Examples, page 122 • Saving a Copy of an Image on a Server Examples, page 124 • Copying a Configuration File from a Server to the Running Configuration Example, page 126 copy CF-122 Cisco IOS Configuration Fundamentals Command Reference April 2010 • Copying a Configuration File from a Server to the Startup Configuration Example, page 126 • Copying the Running Configuration to a Server Example, page 126 • Copying the Startup Configuration to a Server Example, page 127 • Saving the Current Running Configuration Example, page 127 • Moving Configuration Files to Other Locations Examples, page 127 • Copying a File from a Remote Web Server Examples, page 129 • Copying an Image from the Master RSP Card to the Slave RSP Card Example, page 129 Verifying the Integrity of the Image Before It Is Copied Example The following example shows how to specify image verification before copying an image: Router# copy /verify tftp://10.1.1.1/cisco/c7200-js-mz disk0: Destination filename [c7200-js-mz]?

Release Modification 12.2(33)SXH This command was introduced. 12.2(33)SCC The command was introduced for the Cisco uBR10012 router in the Cisco IOS Software Release 12.2(33)SCC. copy logging system CF-134 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines Cisco Universal Broadband Router 10012 The System Event Archive (SEA) feature is used to address the debug trace and system console constraints. Use the copy logging system command to copy the major and critical events stored in the sea_log.dat file, to the destination file system. Note To store the system event logs, the SEA requires either the PCMCIA ATA disk or Compact Flash Disk in compact flash adapter for PRE2. The following example shows how to copy the SEA to the file system of disk0: Router# copy logging system disk0: Destination filename [sea_log.dat]? The following example shows how to copy the SEA using the remote file copy function (rcp): Router# copy logging system rcp: Address or name of remote host []? 192.0.2.1 Destination username [Router]? username1 Destination filename [sea_log.dat]? /auto/tftpboot-users/username1/sea_log.dat Related Commands clear logging system Clears the event records stored in the SEA. logging system Enables or disables SEA logging system. show logging system Displays the SEA logging system disk. copy xmodem: CF-135 Cisco IOS Configuration Fundamentals Command Reference April 2010 copy xmodem: To copy a Cisco IOS image from a local or remote computer (such as a PC, Macintosh, or UNIX workstation) to Flash memory on a Cisco 3600 series router using the Xmodem protocol, use the copy xmodem: command in EXEC mode. copy xmodem: flash-filesystem: Syntax Description Command Modes EXEC Command History Usage Guidelines This command is a form of the copy command. The copy xmodem: and copy xmodem commands are identical. See the description of the copy command for more information. Copying a file using FTP, rcp, or TFTP is much faster than copying a file using Xmodem. Use the copy xmodem: command only if you do not have access to an FTP, TFTP, or rcp server. This copy operation is performed through the console or AUX port. The AUX port, which supports hardware flow control, is recommended. No output is displayed on the port over which the transfer is occurring. You can use the logging buffered command to log all router messages sent to the console port during the file transfer. Examples The following example initiates a file transfer from a local or remote computer to the router’s internal Flash memory using the Xmodem protocol: copy xmodem: flash: Related Commands flash-filesystem: Destination of the copied file, followed by a colon. Release Modification 11.2 P This command was introduced. 12.2(15)T This command is no longer supported in Cisco IOS Mainline or Technology-based (T) releases. It may continue to appear in Cisco IOS 12.2S-family releases. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description copy Copies any file from a source to a destination. copy ymodem: Copies a Cisco IOS image from a local or remote computer (such as a PC, Macintosh, or UNIX workstation) to Flash memory on a Cisco 3600 series router using the Ymodem protocol. copy ymodem: CF-136 Cisco IOS Configuration Fundamentals Command Reference April 2010 copy ymodem: To copy a Cisco IOS image from a local or remote computer (such as a PC, Macintosh, or UNIX workstation) to Flash memory on a Cisco 3600 series router using the Ymodem protocol, use the copy ymodem: command in EXEC mode. copy ymodem: flash-filesystem: Syntax Description Command Modes EXEC Command History Usage Guidelines The copy ymodem: and copy ymodem commands are identical.

Command Description copy xmodem: Copies a Cisco IOS image from a local or remote computer (such as a PC, Macintosh, or UNIX workstation) to Flash memory on a Cisco 3600 series router using the Xmodem protocol. copy /noverify CF-137 Cisco IOS Configuration Fundamentals Command Reference April 2010 copy /noverify To disable the automatic image verification for the current copy operation, use the copy /noverify command. copy /noverify source-url destination-url Syntax Description Defaults Verification is done automatically after completion of a copy operation. Command Modes Privileged EXEC Command History Usage Guidelines The exact format of the source and destination URLs varies according to the file or directory location. You may enter either an alias keyword for a particular file or an alias keyword for a file system type (not a file within a type). Timesaver Aliases are used to cut down on the amount of typing that you need to perform. For example, it is easier to type copy run start (the abbreviated form of the copy running-config startup-config command) than it is to type copy system:r nvram:s (the abbreviated form of the copy system:running-config nvram:startup-config command). These aliases allow you to continue using some of the common commands that are used in previous versions of Cisco IOS software. Table 23 shows two keyword shortcuts to URLs. source-url Location URL or alias of the source file or directory to be copied; see the “Usage Guidelines” section for additional information. destination-url Destination URL or alias of the copied file or directory; see the “Usage Guidelines” section for additional information. Release Modification 12.2(14)SX Support for this command was introduced on the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. copy /noverify CF-138 Cisco IOS Configuration Fundamentals Command Reference April 2010 Table 24 through Table 26 list aliases by file system type. If you do not specify an alias, the system looks for a file in the current directory. Table 24 lists the URL prefix aliases for special (opaque) file systems, Table 25 lists the URL prefix aliases for network file systems, and Table 26 lists the URL prefix aliases for local writable storage file systems. Table 23 Common Keyword Aliases to URLs Keyword Source or Destination running-config (Optional) Specifies the alias for the system:running-config URL. This keyword does not work in the more and show file command syntaxes. startup-config (Optional) Specifies the alias for the nvram:startup-config URL. The nvram:startup-config keyword represents the configuration file that is used during initialization (startup). This file is contained in NVRAM. This keyword does not work in more and show file EXEC command syntaxes. Table 24 URL Prefix Aliases for Special File Systems Alias Source or Destination flh: Source URL for Flash load helper log files. nvram: Router NVRAM. You can copy the startup configuration into or from NVRAM. You can also display the size of a private configuration file. null: Null destination for copies or files. You can copy a remote file to null to determine its size. system: Source or destination URL for system memory, which includes the running configuration. xmodem: Source destination for the file from a network device that uses the Xmodem protocol. ymodem: Source destination for the file from a network device that uses the Ymodem protocol. Table 25 URL Prefix Aliases for Network File Systems Alias Source or Destination ftp: Source or destination URL for an FTP network server. The syntax for this alias is as follows: ftp:[[[//username [:password]@]location]/directory]/filename. rcp: Source or destination URL for an rcp network server. The syntax for this alias is as follows: rcp:[[[//username@]location]/directory]/filename. tftp: Source or destination URL for a TFTP network server. The syntax for this alias is tftp:[[//location]/directory]/filename. copy /noverify CF-139 Cisco IOS Configuration Fundamentals Command Reference April 2010 You can enter on the command line all necessary source- and destination-URL information and the username and password to use, or you can enter the copy command and have the switch prompt you for any missing information. If you enter information, choose one of the following three options: running-config, startup-config, or a file system alias (see Table 23 through Table 26). The location of a file system dictates the format of the source or destination URL. The colon is required after the alias. However, earlier commands that do not require a colon remain supported but are unavailable in context-sensitive help. The entire copying process may take several minutes and differs from protocol to protocol and from network to network. In the alias syntax for ftp:, rcp:, and tftp:, the location is either an IP address or a hostname. The filename is specified for the directory that is used for file transfers. Enter the file verify auto command to set up verification globally. Examples This example shows how to disable the automatic image verification for the current copy operation: Router# copy /noverify tftp: sup-bootflash: ................................................. Table 26 URL Prefix Aliases for Local Writable Storage File Systems Alias Source or Destination bootflash: Source or destination URL for boot flash memory. disk0: and disk1: Source or destination URL of rotating media. flash: Source or destination URL for Flash memory. This alias is available on all platforms. For platforms that lack a Flash: device, note that flash: is aliased to slot0:, allowing you to refer to the main Flash memory storage area on all platforms. slavebootflas h: Source or destination URL for internal Flash memory on the slave RSP card of a device that is configured for HSA. slaveram: NVRAM on a slave RSP card of a device that is configured for HSA. slavedisk0: Source or destination URL of the first PCMCIA card on a slave RSP card of a device that is configured for HSA. slavedisk1: Source or destination URL of the second PCMCIA slot on a slave RSP card of a device that is configured for HSA. slaveslot0: Source or destination URL of the first PCMCIA card on a slave RSP card of a router configured for HSA—Available on systems that are configured with a Supervisor Engine 2. slaveslot1: Source or destination URL of the second PCMCIA slot on a slave RSP card of a router configured for HSA—Available on systems that are configured with a Supervisor Engine 2. slot0: Source or destination URL of the first PCMCIA Flash memory card—Available on systems that are configured with a Supervisor Engine 2. slot1: Source or destination URL of the second PCMCIA Flash memory card—Available on systems that are configured with a Supervisor Engine 2. copy /noverify CF-140 Cisco IOS Configuration Fundamentals Command Reference April 2010 [OK - 24301348 bytes] 24301348 bytes copied in 157.328 secs (154463 bytes/sec) Router# Related Commands Command Description file verify auto Verifies the compressed Cisco IOS image checksum. verify Verifies the checksum of a file on a Flash memory file system or compute an MD5 signature for a file. databits CF-141 Cisco IOS Configuration Fundamentals Command Reference April 2010 databits To set the number of data bits per character that are interpreted and generated by the router hardware, use the databits command in line configuration mode. To restore the default value, use the no form of the command. databits {5 | 6 | 7 | 8} no databits Syntax Description Defaults Eight data bits per character Command Modes Line configuration Command History Usage Guidelines The databits line configuration command can be used to mask the high bit on input from devices that generate 7 data bits with parity. If parity is being generated, specify 7 data bits per character. If no parity generation is in effect, specify 8 data bits per character. The other keywords are supplied for compatibility with older devices and generally are not used. Examples The following example sets the number of data bits per character to seven on line 4: Router(config)# line 4 Router(config-line)# databits 7 Related Commands 5 Five data bits per character. 6 Six data bits per character. 7 Seven data bits per character. 8 Eight data bits per character. This is the default. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

To restore the default value, use the no form of this command. default-value exec-character-bits {7 | 8} no default-value exec-character-bits Syntax Description Defaults 7-bit ASCII character set Command Modes Global configuration Command History Usage Guidelines Configuring the EXEC character width to 8 bits allows you to add graphical and international characters in banners, prompts, and so on. However, setting the EXEC character width to 8 bits can also cause failures. If a user on a terminal that is sending parity enters the help command, an “unrecognized command” message appears because the system is reading all 8 bits, although the eighth bit is not needed for the help command. Examples The following example selects the full 8-bit ASCII character set for EXEC banners and prompts: Router(config)# default-value exec-character-bits 8 Related Commands 7 Selects the 7-bit ASCII character set. This is the default. 8 Selects the full 8-bit ASCII character set. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

By default, only the minimum status messages are displayed on the console. If you specify the optional wait keyword, the Cisco IOS software is not automatically reloaded on the line card after the test completes. wait (Optional) Stops the automatic reloading of the Cisco IOS software on the line card after the completion of the field diagnostic testing. If you use this keyword, you must use the microcode reload slot global configuration command, or manually remove and insert the line card (to power it up) in the slot so that the GRP will recognize the line card and download the Cisco IOS software image to the line card. Release Modification 11.2 GS This command was introduced to support the Cisco 12000 series GSR. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. diag CF-151 Cisco IOS Configuration Fundamentals Command Reference April 2010 Diagnostics will stop and ask you for confirmation before altering the router’s configuration. For example, running diagnostics on a SFC or CSC will cause the fabric to go from full bandwidth to one-fourth bandwidth. Bandwidth is not affected by GRP or line card diagnostics. The field diagnostic software image is bundled with the Cisco IOS software and is downloaded automatically from the GRP to the target line card prior to testing. Caution Performing field diagnostics on a line card stops all activity on the line card. Before the diag EXEC command begins running diagnostics, you are prompted to confirm the request to perform field diagnostics on the line card. In normal mode, if a test fails, the title of the failed test is displayed on the console. However, not all tests that are performed are displayed. To view all the tests that are performed, use the verbose keyword. After all diagnostic tests are completed on the line card, a PASSED or TEST FAILURE message is displayed. If the line card sends a PASSED message, the Cisco IOS software image on the line card is automatically reloaded unless the wait keyword is specified. If the line card sends a TEST FAILURE message, the Cisco IOS software image on the line card is not automatically reloaded. If you want to reload the line card after it fails diagnostic testing, use the microcode reload slot global configuration command. Note When you stop the field diagnostic test, the line card remains down (that is, in an unbooted state). In most cases, you stopped the testing because you need to remove the line card or replace the line card. If that is not the case, and you want to bring the line card back up (that is, online), you must use the microcode reload global configuration command or power cycle the line card. If the line card fails the test, the line card is defective and should be replaced. In future releases this might not be the case because DRAM and SDRAM SIMM modules might be field replaceable units. For example, if the DRAM test failed you might only need to replace the DRAM on the line card. For more information, refer to the Cisco 12000 series installation and configuration guides. Examples In the following example, a user is shown the output when field diagnostics are performed on the line card in slot 3. After the line card passes all field diagnostic tests, the Cisco IOS software is automatically reloaded on the card. Before starting the diagnostic tests, you must confirm the request to perform these tests on the line card because all activity on the line card is halted. The total/indiv. timeout set to 600/220 sec. message indicates that 600 seconds are allowed to perform all field diagnostics tests, and that no single test should exceed 220 seconds to complete.

To skip all diagnostic tests, use the no form of this command. diagnostic bootup level {minimal | complete} no diagnostic bootup level Syntax Description Command Default None Command Modes Global configuration (config) Command History Usage Guidelines Setting the diagnostic level determines the level of testing that occurs when the system or module is reset. The two levels are as follows: • Complete—Runs all tests. • Minimal—Runs only EARL tests for the supervisor engine and loopback tests for all ports in the system. Note Although the default is minimal, you can set the diagnostic level to complete for troubleshooting hardware problems. In certain circumstances, you might want to skip the bootup online diagnostics completely. For example, you might skip the bootup online diagnostics to verify that a port is as bad as online diagnostics reports. To skip online diagnostic testing completely, use the no diagnostic bootup level command. For information on the diagnostic test types, use the show diagnostic command. minimal Specifies minimal diagnostics. See the Usage Guidelines section for additional information. complete Specifies complete diagnostics. See the Usage Guidelines section for additional information.

Enter the [no] diagnostic monitor test {test-id | test-id-range | all} command to enable or disable the specified health monitoring test. When entering the diagnostic monitor {module num} test {test-id | test-id-range | all} command, observe the following: • Required – Isolate network traffic by disabling all connected ports and do not pump test packets during the test. – Remove all modules for testing FIB TCAM and SSRAM memory on the PFC of the supervisor engine. – Reset the system or the test module before putting the system back into the normal operating mode. • Recommended – If the DFC module is present, remove all modules, and then reboot the system before starting the memory test on the central PFC3B of the supervisor engine. – Turn off all background health-monitoring tests on the supervisor engine and the modules using the no diagnostic monitor {module num} test {test-id | test-id-range | all} command. The FIB TCAM test for central PFC3BXL or PFC3B (on the supervisor engine) takes approximately 4 hours and 30 minutes. The FIB TCAM test for the distributed PFC3BXL or PFC3B (on the DFC module) takes approximately 16 hours. You can run the FIB TCAM test on multiple DFC3BX modules simultaneously. Cisco UBR10012 Router The command syntax to refer a line card or SPAs is different on Cisco UBR10012 Router. The keyword is slot x for a full-height line card, slot x/y for a half-height card, and bay x/y for a SPA. To monitor a diagnostic test periodically, you first need to configure the hours, minutes, and seconds interval to run the diagnostic test using the diagnostic monitor interval command. An error message is displayed, if the interval is not configured before enabling the monitoring. To store log details for failed tests, execute the diagnostic monitor syslog command. A threshold value to specify the maximum count for allowed failures is configured using the diagnostic monitor threshold command. The failed test results can be viewed using the show diagnostic results command, after the number of failed test reaches the maximum number of allowed failures configured using the diagnostic monitor threshold command. diagnostic monitor CF-163 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following example shows how to run the specified test every 3 days, 10 hours, and 2 minutes: Router(config)# diagnostic monitor interval module 1 test 1 day 3 hours 10 min 2 The following example shows how to enable the generation of a syslog message when any health-monitoring test fails: Router(config)# diagnostic monitor syslog Cisco UBR10012 Router The following example shows a sample output of an error message displayed when monitoring is enabled before configuring the test interval: Router(config)# diagnostic monitor bay 1/0 test 2 Aug 12 18:04:56.280: %DIAG-3-MONITOR_INTERVAL_ZERO: Bay 1/0: Monitoring interval is 0.

If such levels are configured on a system, using this command with the privilege-level option allows you to exit to a lower security level. If a level is not specified, the user will exit to the user EXEC mode, which is the default. Note Five EXEC commands are associated with privilege level 0: disable, enable, exit, help, and logout. If you configure a privilege level greater than 0, these five commands will not be included in the command set for that privilege level. Examples In the following example, the user enters privileged EXEC mode using the enable command, then exits back to user EXEC mode using the disable command. Note that the prompt for user EXEC mode is >, and the prompt for privileged EXEC mode is #. Router> enable Password: Router# disable Router> Related Commands privilege-level (Optional) Specific privilege level (other than user EXEC mode). Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Cisco IOS XE Release 2.1 This command was introduced on the Cisco ASR 1000 Series Routers, and became available in diagnostic mode. Command Description enable Enables higher privilege level access, such as privileged EXEC mode. disconnect-character CF-178 Cisco IOS Configuration Fundamentals Command Reference April 2010 disconnect-character To define a character to disconnect a session, use the disconnect-character command in line configuration mode. To remove the disconnect character, use the no form of this command. disconnect-character ascii-number no disconnect-character Syntax Description Defaults No disconnect character is defined. Command Modes Line configuration Command History Usage Guidelines See the “ASCII Character Set and Hex Values” appendix for a list of ASCII characters. The Break character is represented by zero; NULL cannot be represented. To use the session-disconnect character in normal communications, precede it with the escape character. Examples The following example defines the disconnect character for virtual terminal line 4 as Escape, which is decimal character 27: Router(config)# line vty 4 Router(config-line)# disconnect-character 27 ascii-number Decimal representation of the session disconnect character. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. dispatch-character CF-179 Cisco IOS Configuration Fundamentals Command Reference April 2010 dispatch-character To define a character that causes a packet to be sent, use the dispatch-character command in line configuration mode. To remove the definition of the specified dispatch character, use the no form of this command. dispatch-character ascii-number1 [ascii-number2 . . . ascii-number] no dispatch-character ascii-number1 [ascii-number2 . . . ascii-number] Syntax Description Defaults No dispatch character is defined. Command Modes Line configuration Command History Usage Guidelines See the “ASCII Character Set and Hex Values” appendix for a list of ASCII characters. The dispatch-character command defines one or more dispatch characters that cause a packet to be sent even if the dispatch timer has not expired. Use of a dispatch character causes the Cisco IOS software to attempt to buffer characters into larger-sized packets for transmission to the remote host. Enable the dispatch-character command from the session that initiates the connection, not from the incoming side of a streaming Telnet session. This command can take multiple arguments, so you can define any number of characters as dispatch characters. Examples The following example defines the Return character (decimal 13) as the dispatch character for virtual terminal line (vty) line 4: Router(config)# line vty 4 Router(config-line)# dispatch-character 13 ascii-number1 Decimal representation of the desired dispatch character. ascii-number2 . . . ascii-number (Optional) Additional decimal representations of characters. This syntax indicates that you can define any number of characters as dispatch characters. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. dispatch-character CF-180 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description dispatch-machine Specifies an identifier for a TCP packet dispatch state machine on a particular line. dispatch-timeout Sets the character dispatch timer. state-machine Specifies the transition criteria for the state of a particular state machine. terminal dispatch-character Defines a character that causes a packet to be sent for the current session. dispatch-machine CF-181 Cisco IOS Configuration Fundamentals Command Reference April 2010 dispatch-machine To specify an identifier for a TCP packet dispatch state machine on a particular line, use the dispatch-machine command in line configuration mode. To disable a state machine on a particular line, use the no form of this command. dispatch-machine name no dispatch-machine Syntax Description Defaults No dispatch state machine identifier is defined. Command Modes Line configuration Command History Usage Guidelines When the dispatch-timeout command is specified, a packet being built will be sent when the timer expires, and the state will be reset to zero. Any dispatch characters specified using the dispatch-character command are ignored when a state machine is also specified. If a packet becomes full, it will be sent regardless of the current state, but the state will not be reset. The packet size depends on the traffic level on the asynchronous line and the dispatch-timeout value. There is always room for 60 data bytes. If the dispatch-timeout value is greater than or equal to 100 milliseconds, a packet size of 536 (data bytes) is allocated. Examples The following example specifies the name linefeed for the state machine: Router(config)# state-machine linefeed 0 0 9 0 Router(config)# state-machine linefeed 0 11 255 0 Router(config)# state-machine linefeed 0 10 10 transmit Router(config)# line 1 Router(config-line)# dispatch-machine linefeed Related Commands name Name of the state machine that determines when to send packets on the asynchronous line. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description dispatch-character Defines a character that causes a packet to be sent. dispatch-machine CF-182 Cisco IOS Configuration Fundamentals Command Reference April 2010 dispatch-timeout Sets the character dispatch timer. state-machine Specifies the transition criteria for the state of a particular state machine. Command Description dispatch-timeout CF-183 Cisco IOS Configuration Fundamentals Command Reference April 2010 dispatch-timeout To set the character dispatch timer, use the dispatch-timeout command in line configuration mode. To remove the timeout definition, use the no form of this command. dispatch-timeout milliseconds no dispatch-timeout Syntax Description Defaults No dispatch timeout is defined. Command Modes Line configuration Command History Usage Guidelines Use this command to increase the processing efficiency for the remote host. The dispatch-timeout line configuration command causes the software to buffer characters into packets for transmission to the remote host. The Cisco IOS software sends a packet a specified amount of time after the first character is put into the buffer. You can use the dispatch-timeout and dispatch-character line configuration commands together. In this case, the software dispatches a packet each time the dispatch character is entered, or after the specified dispatch timeout interval, depending on which condition is met first. Note The system response time might appear intermittent if the timeout interval is greater than 100 milliseconds and remote echoing is used. For lines with a reverse-Telnet connection, use a dispatch-timeout value less than 10 milliseconds. Examples The following example sets the dispatch timer to 80 milliseconds for virtual terminal line (vty) lines 0 through 4: Router(config)# line vty 0 4 Router(config-line)# dispatch-timeout 80 milliseconds Integer that specifies the number of milliseconds (ms) that the Cisco IOS software waits after putting the first character into a packet buffer before sending the packet. During this interval, more characters can be added to the packet, which increases the processing efficiency of the remote host. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. dispatch-timeout CF-184 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description buffer-length Specifies the maximum length of data streams forwarded on a line. dispatch-character Defines a character that causes a packet to be sent. dispatch-machine Specifies an identifier for a TCP packet dispatch state machine on a particular line. state-machine Specifies the transition criteria for the state of a particular state machine. terminal dispatch-timeout Sets the character dispatch timer for the current session. do CF-185 Cisco IOS Configuration Fundamentals Command Reference April 2010 do To execute user EXEC or privileged EXEC commands from global configuration mode or other configuration modes or submodes, use the do command in any configuration mode. do command Syntax Description Command Default A user EXEC or privileged EXEC command is not executed from a configuration mode. Command Modes All configuration modes Command History Usage Guidelines Use this command to execute user EXEC or privileged EXEC commands (such as show, clear, and debug commands) while configuring your routing device. After the EXEC command is executed, the system will return to the configuration mode you were using. Tip This command can be useful for saving your configuration to the startup-config file without having to return to the user EXEC mode or privileged EXEC mode (do copy running-config startup-config) or for checking the status of a feature (using a do show command) while configuring the feature. Caution Do not enter the do command in user EXEC mode or privileged EXEC mode. Interruption of service might occur. You cannot use the do command to execute the configure terminal command because entering the configure terminal command changes the user EXEC mode or privileged EXEC mode to the global configuration mode. You cannot use the do command to execute copy or write commands in the global configuration or any other configuration mode or submode. command The user EXEC or privileged EXEC command to be executed.

To disable this function, use the no form of this command. downward-compatible-config version no downward-compatible-config Syntax Description Defaults Disabled Command Modes Global configuration Command History Usage Guidelines In Cisco IOS Release 10.3, IP access lists changed format. Use the downward-compatible-config command to regenerate a configuration in a format prior to Release 10.3 if you are going to downgrade from your software version to version 10.2 or 10.3. The earliest version value this command accepts is 10.2. When this command is configured, the router attempts to generate a configuration that is compatible with the specified version. Note that this command affects only IP access lists. Under some circumstances, the software might not be able to generate a fully backward-compatible configuration. In such a case, the software issues a warning message. Examples The following example generates a configuration file compatible with Cisco IOS Release 10.2 access lists: Router(config)# downward-compatible-config 10.2 Related Commands version Cisco IOS release number, not earlier than Release 10.2.

Cisco IOS XE Release 2.1 This command became available on the ASR 1000 Series Routers, and became available in diagnostic mode for the first time. enable CF-192 Cisco IOS Configuration Fundamentals Command Reference April 2010 If an enable password has not been set, only enable mode can be accessed through the console connection. Security levels can be set by an administrator using the enable password and privilege level commands. Up to 16 privilege levels can be specified, using the numbers 0 through 15. Using these privilege levels, the administrator can allow or deny access to specific commands. Privilege level 0 is associated with user EXEC mode, and privilege level 15 is associated with privileged EXEC mode. For more information on defined privilege levels, see the Cisco IOS Security Configuration Guide and the Cisco IOS Security Command Reference publications. If a level is not specified when entering the enable command, the user will enter the default mode of privileged EXEC (level 15). Accessing a CLI View CLI views restrict user access to specified CLI and configuration information. To configure and access CLI views, users must first enter into root view, which is accomplished via the enable view command (without the view-name argument). Thereafter, users are prompted for a password, which is the same password as the privilege level 15 password. The view-name argument is used to switch from one view to another view. To prevent dictionary attacks, a user is prompted for a password even if an incorrect view name is given. The user is denied access only after an incorrect view name and password are given. Examples In the following example, the user enters privileged EXEC mode (changes to privilege-level 15) by using the enable command without a privilege-level argument. The system prompts the user for a password before allowing access to the privileged EXEC mode. The password is not printed to the screen. The user then exits back to user EXEC mode using the disable command. Note that the prompt for user EXEC mode is the greater than symbol (>), and the prompt for privileged EXEC mode is the number sign (#). Router> enable Password: Router# disable Router> The following example shows which commands are available inside the CLI view “first” after the user has logged into this view: Router# enable view first Password: 00:28:23:%PARSER-6-VIEW_SWITCH:successfully set to view 'first'.

Defaults No default behavior or values. Command Modes Global configuration Command History Usage Guidelines This command will bring you back to privileged EXEC mode regardless of what configuration mode or configuration submode you are in. Note This global configuration command can be used in any configuration mode. Use this command when you are done configuring the system and you want to return to EXEC mode to perform verification steps. Examples In the following example, the end command is used to exit from ALPS ASCU configuration mode and return to privileged EXEC mode. A show command is used in privileged EXEC mode to verify the configuration. Router# configure terminal Router(config)# interface serial 1:1 Router(config-if)# alps ascu 4B Router(config-alps-ascu)# end Router# show interface serial 1:1 Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description exit (global) Exits from the current configuration mode. environment-monitor shutdown temperature CF-195 Cisco IOS Configuration Fundamentals Command Reference April 2010 environment-monitor shutdown temperature To enable monitoring of the environment sensors, use the environment-monitor shutdown temperature command in global configuration mode. To disable monitoring of the environment sensors, use the no form of this command. environment-monitor shutdown temperature [rommon | powerdown] no environment-monitor shutdown temperature [rommon | powerdown] Syntax Description Defaults By default, rommon is enabled. Command Modes Global configuration Command History Examples This example shows how to place the supervisor engine in ROMMON when a major active alarm occurs: Router(config)# environment-monitor shutdown temperature rommon Router(config)# This example shows how to power down the supervisor engine when a major active alarm occurs: Router(config)# environment-monitor shutdown temperature powerdown Router(config)# rommon (Optional) Places the supervisor engine in ROMMON when a major active alarm is identified. powerdown (Optional) Powers down the supervisor engine when a new active major alarm is identified.

To disable the ambient temperature control, use the no form of this command. environment temperature-controlled no environment temperature-controlled Syntax Description This command has no arguments or keywords. Defaults This command has no default settings. Command Modes Global configuration Command History Usage Guidelines This command does not affect temperature monitoring and alarm thresholds; it only affects whether a module may be powered on. The software does not validate the inlet temperature. If you enter the no form of this command and the cooling capacity is reduced below the module cooling requirement, a syslog warning (and SNMP alarm) is generated. This module status does not change, and an environmental alarm is not raised when you enter the no form of this command. Examples This example shows how to enable the ambient temperature control: Router(config)# environment temperature-controlled Router(config)# This example shows how to disable the ambient temperature control: Router(config)# no environment temperature-controlled Router(config)# Release Modification 12.2(14)SX Support for this command was introduced on the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. erase CF-197 Cisco IOS Configuration Fundamentals Command Reference April 2010 erase To erase a file system or all files available on a file system, use the erase command in privileged EXEC or diagnostic mode. erase {/all nvram: | /no-squeeze-reserve-space | filesystem: | startup-config} Cisco 7600 Series Routers and Cisco ASR1000 Series Routers erase {/all nvram: | filesystem: | startup-config} Syntax Description Command Modes Privileged EXEC (#) Diagnostic (#) Command History Usage Guidelines The erase nvram: command replaces the write erase command and the erase startup-config command. Caution When you use the erase command to erase a file system, you cannot recover the files in the file system. The word help feature is disabled for the erase command. You must enter the complete command name to enable the command. The parser does not complete the command name if you enter partial syntax of the command and press the Tab key. For more information on the word help feature, refer to the Using the Cisco IOS Command-Line Interface feature guide. The erase command can be used on Class B and Class C flash file systems only. /all Erases all files in the specified file system. filesystem: File system name, followed by a colon. For example, flash: or nvram:. /no-squeeze-reserve-space Disables the squeeze operation to conserve memory and makes the erase command compatible with older file systems. startup-config Erases the contents of the configuration memory. Release Modification 11.0 This command was introduced. 12.2(11)T This command was modified. The /no-squeeze-reserve-space keyword was added. 12.2(14)SX This command was modified. Support for this command was added for the Supervisor Engine 720. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Cisco IOS XE Release 2.1 This command was modified. The command was introduced in diagnostic mode on the Cisco ASR 1000 Series Routers, and the /all keyword was added. erase CF-198 Cisco IOS Configuration Fundamentals Command Reference April 2010 Class A flash file systems cannot be erased. You can delete individual files using the delete command and then reclaim the space using the squeeze command. You can use the format command to format the flash file system. The format command when used on ATA disk clears the File Allocation Table (FAT) and root directory entries only. The data is not erased. The erase nvram: command erases NVRAM. On Class A file system platforms, if the CONFIG_FILE variable specifies a file in flash memory, the specified file will be marked “deleted.” The erase /all nvram: command erases all files on NVRAM, including private NVRAM. The /no-squeeze-reserve-space keyword is available on systems with small amounts of flash memory in order to conserve memory. When a squeeze operation is performed, the last two erase sectors are permanently reserved for the squeeze logs and squeeze buffer. The /no-squeeze-reserve-space keyword prevents the reservation of space that guarantees the ability to run the squeeze command. Disabling the squeeze operation keeps these memory sectors free. If any sectors using squeeze data are detected, they will be erased when the /no-squeeze-reserve-space keyword is used. The /no-squeeze-reserve-space keyword increases the available amount of usable flash space, but you may not be able to run the squeeze command. This is typically fine if the file system (such as flash) is used to store a single, large file. For example, an IOS image. On Class C flash file systems, space is dynamically reclaimed when you use the delete command. You can also use either the format or erase command to reinitialize a Class C flash file system. Note Use the context-sensitive help to determine which file systems can be used for the erase command. The output will vary based on the platform. Examples The following example shows how to erase the NVRAM, including the startup configuration located there: Router# erase nvram: The following example shows how to erase all of partition 2 in internal flash memory: Router# erase flash:2 System flash directory, partition 2: File Length Name/status 1 1711088 dirt/images/c3600-i-mz [1711152 bytes used, 15066064 available, 16777216 total] Erase flash device, partition 2?

[default = 2] erase CF-199 Cisco IOS Configuration Fundamentals Command Reference April 2010 The system will prompt only if there are two or more read/write partitions. If the partition entered is not valid or is the read-only partition, the process terminates. You can enter a partition number, a question mark (?) for a directory display of all partitions, or a question mark and a number (?number) for directory display of a particular partition. The default is the first read/write partition.

To disable the error-disable detection, use the no form of this command. errdisable detect cause {all | dtp-flap | l2ptguard | link-flap | packet-buffer-error | pagp-flap | udld} no errdisable detect cause {all | dtp-flap | l2ptguard | link-flap | pagp-flap | udld} Syntax Description Defaults Enabled for all causes Command Modes Global configuration Command History Usage Guidelines Note Entering the no errdisable detect cause packet-buffer-error command allows you to detect the fault that triggers a power cycle of the affected module. A cause (bpduguard, dtp-flap, link-flap, pagp-flap, root-guard, udld) is defined as the reason why the error-disabled state occurred. When a cause is detected on an interface, the interface is placed in an error-disabled state (an operational state that is similiar to the link-down state). You must enter the shutdown and then the no shutdown commands to recover an interface manually from the error-disable state. all Specifies error-disable detection for all error-disable causes. dtp-flap Specifies detection for the DTP flap error-disable cause. l2ptguard Specifies detection for the Layer 2 protocol-tunnel error-disable cause. link-flap Specifies detection for the link flap error-disable cause. packet-buffer-error Causes the packet buffer error to error-disable the affected port. pagp-flap Specifies detection for the PAgP flap error-disable cause. udld Specifies detection for the UDLD error-disable cause.

Range: 30 to 86400. Default: 300. Release Modification 12.2(14)SX This command was introduced on the Supervisor Engine 720. 12.2(17d)SXB This command was implemented on the Supervisor Engine 2. 12.2(18)SXD The arp-inspection keyword was added. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. errdisable recovery CF-204 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines A cause (bpduguard, channel-misconfig, dhcp-rate-limit, dtp-flap, l2ptguard, link-flap, pagp-flap, psecure-violation, security-violation, udld, or unicast-flood) is defined as the reason why the error-disabled state occurred. When a cause is detected on an interface, the interface is placed in an error-disabled state (an operational state that is similar to the link-down state). If you do not enable error-disable recovery for the cause, the interface stays in the error-disabled state until a shutdown and no shutdown occurs. If you enable recovery for a cause, the interface is brought out of the error-disabled state and allowed to retry operation once all the causes have timed out. You must enter the shutdown command and then the no shutdown command to manually recover an interface from the error-disabled state. Note Each time you want enter the errdisable recovery cause command to add a new reason for recovery, it takes up a separate line; each new reason does not get appended to the original single line. This means you must enter each new reason separately. Examples This example shows how to enable the recovery timer for the BPDU-guard error-disable cause: Router(config)# errdisable recovery cause bpduguard This example shows how to set the recovery timer to 300 seconds: Router(config)# errdisable recovery interval 300 Related Commands Command Description show errdisable recovery Displays the information about the error-disable recovery timer. show interfaces status Displays the interface status or a list of interfaces in an error-disabled state on LAN ports only. escape-character CF-205 Cisco IOS Configuration Fundamentals Command Reference April 2010 escape-character To define a system escape character, use the escape-character command in line configuration mode. To set the escape character to Break, use the no or default form of this command. escape-character {break | char | default | none | soft} no escape-character [soft] default escape-character [soft] Syntax Description Defaults The default escape key sequence is Ctrl-Shift-6 (Ctrl-^) or Ctrl-Shift-6, X (^^X). The X is generally only required for modem connections. The default escape-character command sets the escape character to Break (the default setting for Break is Ctrl-C). Command Modes Line configuration Command History Usage Guidelines See the “ASCII Character Set and Hexidecimal Values” appendix for a list of ASCII characters. The escape character (or key sequence) suspends any actively running processes and returns you to privileged EXEC mode or, if a menu is being used, to the system menu interface. The escape character is used for interrupting or aborting a process started by previously executed command. Examples of processes from which you can escape include Domain-Name lookup, ping, trace, and Telnet sessions initiated from the device to which you are connected. To view the current setting of the escape sequence for a line, use the show line command followed by the specific line identifier (for example, show line 0, or show line console). The default escape sequence for a line is often displayed as ^^X . The first caret symbol represents the Control (Ctrl) key, the second caret symbol is literal (Shift-6), and the X is literal (for most systems, the X is not required). break Sets the escape character to Break. Note that the Break key should not be used as an escape character on a console terminal. char Character (for example, !) or its ASCII decimal representation (integer in the range of 0 to 255) to be used as the escape character. default Sets the escape key sequence to the default of Ctrl-^, X. none Disables escape entirely. soft Sets an escape character that will wait until pending input is processed before it executes. Release Modification 10.0 This command was introduced. 11.3 The soft keyword was added. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. escape-character CF-206 Cisco IOS Configuration Fundamentals Command Reference April 2010 To set the escape key for the active terminal line session, use the terminal escape-character command. The Break key cannot be used as an escape character on a console terminal because the Cisco IOS software interprets Break as an instruction to halt the system. Depending upon the configuration register setting, break commands issued from the console line either will be ignored or cause the server to shut down. To send an escape sequence over a Telnet connection, press Ctrl-Shift-6 twice. The escape-character soft form of this command defines a character or character sequence that will cause the system to wait until pending input is processed before suspending the current session. This option allows you to program a key sequence to perform multiple actions, such as using the F1 key to execute a command, then execute the escape function after the first command is executed. The following restrictions apply when using the soft keyword: • The length of the logout sequence must be 14 characters or fewer. • The soft escape character cannot be the same as the generic Cisco escape character, Break, or the characters b, d, n, or s. • The soft escape character should be an ASCII value from 1 to 127. Do not use the number 30. Examples The following example sets the escape character for the console line to the keyboard entry Ctrl-P, which is represented by the ASCII decimal value of 16: Router(config)# line console Router(config-line)# escape-character 16 The following example sets the escape character for line 1 to !, which is represented in the configuration file as the ASCII number 33: Router(config)# line 1 Router(config-line)# escape-character ! Router(config-line)# end Router# show running-config Building configuration... . . . line 1 autoselect during-login autoselect ppp modem InOut transport preferred none transport output telnet escape-character 33 Related Commands Command Description show line Displays information about the specified line connection, or all the lines. terminal escape-character Sets the escape character for the current terminal line for the current session. exec CF-207 Cisco IOS Configuration Fundamentals Command Reference April 2010 exec To allow an EXEC process on a line, use the exec command in line configuration mode. To turn off the EXEC process for the specified line, use the no form of this command. exec no exec Syntax Description This command has no arguments or keywords. Defaults The EXEC processes is enabled on all lines. Command Modes Line configuration Command History Usage Guidelines When you want to allow only an outgoing connection on a line, use the no exec command. The no exec command allows you to disable the EXEC process for connections which may attempt to send unsolicited data to the router. (For example, the control port of a rack of modems attached to an auxiliary port of router.) When certain types of data are sent to a line connection, an EXEC process can start, which makes the line unavailable. When a user tries to Telnet to a line with the EXEC process disabled, the user will get no response when attempting to log on. Examples The following example disables the EXEC process on line 7. Router(config)# line 7 Router(config-line)# no exec Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. exec-banner CF-208 Cisco IOS Configuration Fundamentals Command Reference April 2010 exec-banner To reenable the display of EXEC and message-of-the-day (MOTD) banners on the specified line or lines, use the exec-banner command in line configuration mode. To suppress the banners on the specified line or lines, use the no form of this command. exec-banner no exec-banner Syntax Description This command has no arguments or keywords. Defaults Enabled on all lines Command Modes Line configuration Command History Usage Guidelines This command determines whether the router will display the EXEC banner and the message-of-the-day (MOTD) banner when an EXEC session is created. These banners are defined with the banner exec and banner motd global configuration commands. By default, these banner are enabled on all lines. Disable the EXEC and MOTD banners using the no exec-banner command. This command has no effect on the incoming banner, which is controlled by the banner incoming command. The MOTD banners can also be disabled by the no motd-banner line configuration command, which disables MOTD banners on a line. If the no exec-banner command is configured on a line, the MOTD banner will be disabled regardless of whether the motd-banner command is enabled or disabled. Table 30 summarizes the effects of the exec-banner command and the motd-banner command. For reverse Telnet connections, the EXEC banner is never displayed. Instead, the incoming banner is displayed. The MOTD banner is displayed by default, but it is disabled if either the no exec-banner command or no motd-banner command is configured. Table 31 summarizes the effects of the exec-banner command and the motd-banner command for reverse Telnet connections. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

To restore the default value, use the no form of this command. exec-character-bits {7 | 8} no exec-character-bits Syntax Description Defaults 7-bit ASCII character set Command Modes Line configuration Command History Usage Guidelines Setting the EXEC character width to 8 allows you to use special graphical and international characters in banners, prompts, and so on. However, setting the EXEC character width to 8 bits can cause failures. If a user on a terminal that is sending parity enters the help command, an “unrecognized command” message appears because the system is reading all 8 bits, and the eighth bit is not needed for the help command. Note If you are using the autoselect function, set the activation character to the default (Return) and the value for exec-character-bits to 7. If you change these defaults, the application will not recognize the activation request. Examples The following example enables full 8-bit international character sets, except for the console, which is an ASCII terminal. It illustrates use of the default-value exec-character-bits global configuration command and the exec-character-bits line configuration command. Router(config)# default-value exec-character-bits 8 Router(config)# line 0 Router(config-line)# exec-character-bits 7 7 Selects the 7-bit character set. This is the default. 8 Selects the full 8-bit character set for use of international and graphical characters in banner messages, prompts, and so on. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. exec-character-bits CF-211 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description default-value exec-character-bits Defines the EXEC character width for either 7 bits or 8 bits. default-value special-character-bits Configures the flow control default value from a 7-bit width to an 8-bit width. length Sets the terminal screen length. terminal exec-character-bits Locally changes the ASCII character set used in EXEC and configuration command characters for the current session. terminal special-character-bits Changes the ASCII character widths to accept special characters for the current terminal line and session. exec-timeout CF-212 Cisco IOS Configuration Fundamentals Command Reference April 2010 exec-timeout To set the interval that the EXEC command interpreter waits until user input is detected, use the exec-timeout command in line configuration mode. To remove the timeout definition, use the no form of this command. exec-timeout minutes [seconds] no exec-timeout Syntax Description Defaults 10 minutes Command Modes Line configuration Command History Usage Guidelines If no input is detected during the interval, the EXEC facility resumes the current connection. If no connections exist, the EXEC facility returns the terminal to the idle state and disconnects the incoming session. To specify no timeout, enter the exec-timeout 0 0 command.

This allows you to issue commands remotely; that is, to issue commands without needing to log in to the line card directly. The all form of the command allows you to issue commands to all the line cards without having to log in to each in turn. Though this command does not have a no form, note that it is possible to use the no form of the remotely executed commands used in this command. Tip This command is useful when used with show EXEC commands (such as show version), because you can verify and troubleshoot the features found only on a specific line card. Please note, however, that because not all statistics are maintained on the line cards, the output from some of the show commands might not be consistent. Cisco 12000 GSR Guidelines and Restrictions You can use the execute-on privileged EXEC command only from Cisco IOS software running on the GRP card. slot slot-number Executes the command on the line card in the specified slot. Slot numbers can be chosen from the following ranges: • Cisco 12012 router: 0 to 11 • Cisco 12008 access server: 0 to 7 • Cisco AS5800 access server: 0 to 13 all Executes the command on all line cards. master (AS5800 only) Executes the designated command on a Dial Shelf Controller (DSC). Do not use this option; it is used for technical support troubleshooting only. command Cisco IOS command to remotely execute on the line card. Release Modification 11.2 GS This command was introduced to support Cisco 12000 series Gigabit Switch Routers. 11.3(2)AA This command was implemented in images for the Cisco AS5800 series. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. execute-on CF-214 Cisco IOS Configuration Fundamentals Command Reference April 2010 Timesaver Though you can use the attach privileged EXEC command to execute commands on a specific line card, using the execute-on slot command saves you some steps. For example, first you must use the attach command to connect to the Cisco IOS software running on the line card. Next you must issue the command. Finally you must disconnect from the line card to return to the Cisco IOS software running on the GRP card. With the execute-on slot command, you can perform three steps with one command. In addition, the execute-on all command allows you to perform the same command on all line cards simultaneously. Cisco AS5800 Guidelines and Restrictions The purpose of the command is to conveniently enable certain commands to be remotely executed on the dial shelf cards from the router without connecting to each line card. This is the recommended procedure, because it avoids the possibility of adversely affecting a good configuration of a line card in the process. The execute-on command does not give access to every Cisco IOS command available on the Cisco AS5800 access server. In general, the purpose of the execute-on command is to provide access to statistical reports from line cards without directly connecting to the dial shelf line cards. Caution Do not use this command to change configurations on dial shelf cards, because such changes will not be reflected in the router shelf. Using this command makes it possible to accumulate inputs for inclusion in the show tech-support command. The master form of the command can run a designated command remotely on the router from the DSC card. However, using the console on the DSC is not recommended. It is used for technical support troubleshooting only. The show tech-support command for each dial shelf card is bundled into the router shelf's show tech-support command via the execute-on facility. The execute-on command also support interactive commands such as the following: router: execute-on slave slot slot ping The execute-on command has the same limitations and restrictions as a vty telnet client has; that is, it cannot reload DSC using the following command: router: execute-on slave slot slot reload You can use the execute-on command to enable remote execution of the commands included in the following partial list: • debug dsc clock • show context • show diag • show environment • show dsc clock • show dsi • show dsip • show tech-support execute-on CF-215 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples In the following example, the user executes the show controllers command on the line card in slot 4 of a Cisco 12000 series GSR: Router# execute-on slot 4 show controllers ========= Line Card (Slot 4) ======= Interface POS0 Hardware is BFLC POS lcpos_instance struct 6033A6E0 RX POS ASIC addr space 12000000 TX POS ASIC addr space 12000100 SUNI framer addr space 12000400 SUNI rsop intr status 00 CRC16 enabled, HDLC enc, int clock no loop Interface POS1 Hardware is BFLC POS lcpos_instance struct 6033CEC0 RX POS ASIC addr space 12000000 TX POS ASIC addr space 12000100 SUNI framer addr space 12000600 SUNI rsop intr status 00 CRC32 enabled, HDLC enc, int clock no loop Interface POS2 Hardware is BFLC POS lcpos_instance struct 6033F6A0 RX POS ASIC addr space 12000000 TX POS ASIC addr space 12000100 SUNI framer addr space 12000800 SUNI rsop intr status 00 CRC32 enabled, HDLC enc, int clock no loop Interface POS3 Hardware is BFLC POS lcpos_instance struct 60341E80 RX POS ASIC addr space 12000000 TX POS ASIC addr space 12000100 SUNI framer addr space 12000A00 SUNI rsop intr status 00 CRC32 enabled, HDLC enc, ext clock no loop Router# Related Commands Command Description attach Connects you to a specific line card for the purpose of executing commands using the Cisco IOS software image on that line card. exit (EXEC) CF-216 Cisco IOS Configuration Fundamentals Command Reference April 2010 exit (EXEC) To close an active terminal session by logging off the router, use the exit command in EXEC mode. exit Syntax Description This command has no arguments or keywords. Defaults No default behavior or values Command Modes EXEC Command History Usage Guidelines Use the exit command in EXEC mode to exit the active session (log off the device). This command can be used in any EXEC mode (such as User EXEC mode or Privileged EXEC mode) to exit from the EXEC process. Examples In the following example, the exit (global) command is used to move from global configuration mode to privileged EXEC mode, the disable command is used to move from privileged EXEC mode to user EXEC mode, and the exit (EXEC) command is used to log off (exit the active session): Router(config)# exit Router# disable Router> exit Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

Defaults No default behavior or values Command Modes All configuration modes Command History Usage Guidelines The exit command is used in the Cisco IOS CLI to exit from the current command mode to the next highest command mode in the CLI mode hierarchy. For example, use the exit command in global configuration mode to return to privileged EXEC mode. Use the exit command in interface, line, or router configuration mode to return to global configuration mode. Use the exit command in subinterface configuration mode to return to interface configuration mode. At the highest level, EXEC mode, the exit command will exit the EXEC mode and disconnect from the router interface (see the description of the exit (EXEC) command for details). Examples The following example shows how to exit from the subinterface configuration mode and to return to the interface configuration mode: Router(config-subif)# exit Router(config-if)# The following example displays an exit from the interface configuration mode to return to the global configuration mode: Router(config-if)# exit Router(config)# Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

This command affects only prompts for confirmation of operations. The router will always prompt for missing information. Examples The following example configures confirmation prompting for all file operations: Router(config)# file prompt noisy alert (Optional) Prompts only for destructive file operations. This is the default. noisy (Optional) Confirms all file operation parameters. quiet (Optional) Seldom prompts for file operations.

To disable automatic image verification, use the no form of this command. file verify auto no file verify auto Syntax Description This command has no arguments or keywords. Defaults Image verification is not automatically applied to all images that are copied or reloaded onto a router. Command Modes Global configuration Command History Usage Guidelines Image verification is accomplished by verifying the compressed Cisco IOS image checksum. Image verification allows users to automatically verify the integrity of all Cisco IOS images. Thus, users can be sure that the image is protected from accidental corruption, which can occur at any time during transit, starting from the moment the files are generated by Cisco until they reach the user. The file verify auto command enables image verification globally; that is, all images that are to be copied (via the copy command) or reloaded (via the reload command) are automatically verified. Although both the copy and reload commands have a /verify keyword that enables image verification, you must issue the keyword each time you want to copy or reload an image. The file verify auto command enables image verification by default so you no longer have to specify image verification multiple times. If you have enabled image verification by default but prefer to disable verification for a specific image copy or reload, the /noverify keyword along with either the copy or the reload command will override the file verify auto command. Examples The following example shows how to enable automatic image verification: Router(config)# file verify auto Release Modification 12.2(18)S This command was introduced. 12.0(26)S This command was integrated into Cisco IOS Release 12.0(26)S. 12.2(14)SX This command was integrated into Cisco IOS Release 12.2(14)SX and implemented on the Supervisor Engine 720. 12.2(17d)SXB Support was added for the Supervisor Engine 2. 12.3(4)T This command was integrated into Cisco IOS Release 12.3(4)T. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. file verify auto CF-220 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description copy Copies any file from a source to a destination. copy/noverify Disables the automatic image verification for the current copy operation. reload Reloads the operating system. verify Verifies the checksum of a file on a Flash memory file system or computes an MD5 signature for a file. format CF-221 Cisco IOS Configuration Fundamentals Command Reference April 2010 format To format a Class A, Class B, or Class C flash memory file system, use the format command in privileged EXEC or diagnostic mode. Class B and Class C Flash File Systems format filesystem1: Class A Flash File System format [spare spare-number] filesystem1: [[filesystem2:][monlib-filename]] Syntax Description Command Default spare-number: 0 monlib-filename: The monlib file bundled with the system software Command Modes Privileged EXEC (#) Diagnostic (diag) spare (Optional) Reserves spare sectors as specified by the spare-number argument when you format flash memory. spare-number (Optional) Number of the spare sectors to reserve in formatted flash memory. Valid values are from 0 to 16. The default value is 0. filesystem1: Flash memory to format, followed by a colon. Valid values for use with the Cisco 7600 series router are disk0:, disk1:, bootflash:, slot0:, sup-slot0:, and sup-bootflash:; see the “Usage Guidelines” section for additional information. Valid values for use with the ASR1000 Series Routers are bootflash:, harddisk:, stby-harddisk:, obfl:, and usb[0-1];. filesystem2: (Optional) File system containing the monlib file to use for formatting the argument filesystem1 followed by a colon. monlib-filename (Optional) Name of the ROM monitor library file (monlib file) to use for formatting the filesystem1 argument. The default monlib file is the one bundled with the system software. Dual Route Switch Processors (RSP) High System Availability (HSA) Functionality When this command is used with Dual RSPs and you do not specify the monlib-filename argument, the system takes the ROM monitor library file from the slave image bundle. If you specify the monlib-filename argument, the system assumes that the files reside on the slave devices. format CF-222 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command History Usage Guidelines Reserve a certain number of memory sectors as spares, so that if some sectors fail, most of the flash memory card can still be used. Otherwise, you must reformat the flash card after some of the sectors fail. Use this command to format Class A, B, or C flash memory file systems. The Cisco 7600 series router supports only Class A and Class C flash file systems. In some cases, you might need to insert a new Personal Computer Memory Card Industry Association (PCMCIA) flash memory or flash PC card and load images or backup configuration files onto it. Before you can use a new flash memory or flash PC card, you must format it. Sectors in flash memory or flash PC cards can fail. Reserve certain flash memory or flash PC sectors as “spares” by using the optional spare-number argument on the format command to specify 0 to 16 sectors as spares. If you reserve a small number of spare sectors for emergencies, you can still use most of the flash memory or flash PC card. If you specify 0 spare sectors and some sectors fail, you must reformat the flash memory or flash PC card, thereby erasing all existing data. The monlib file is the ROM monitor library. The ROM monitor uses this file to access files in the flash file system. The Cisco IOS system software contains a monlib file. Use the show disk0: all command to display monlib file details. When this command is used with HSA and you do not specify the monlib-filename argument, the system takes the ROM monitor library file from the slave image bundle. If you specify the monlib-filename argument, the system assumes that the files reside on the slave devices. In the command syntax, the filesystem1: argument specifies the device to format and the filesystem2: argument specifies the optional device containing the monlib file used to format the filesystem1: argument. The device determines which monlib file to use, as follows: • If you omit the optional filesystem2: and monlib-filename arguments, the system formats the filesystem1: argument using the monlib file already bundled with the system software. • If you omit only the optional filesystem2: argument, the system formats the filesystem1: argument using the monlib file from the device you specified with the cd command. • If you omit only the optional monlib-filename argument, the system formats filesystem1: using the filesystem2: monlib file. Release Modification 11.0 This command was introduced. 12.2(14)SX Support for this command was added for the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 12.3(14)T Support for Class B Flash (USB Flash and USB eToken) File Systems was added as part of the “USB Storage” feature. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Cisco IOS XE Release 2.1 This command was introduced on the Cisco ASR1000 Series Routers and the following enhancements were introduced: • This command was introduced in diagnostic mode for the first time. The command can be entered in both privileged EXEC and diagnostic mode on the Cisco ASR1000 Series Routers. • The harddisk:, obfl:, stby-harddisk:, stby-usb[0-1]: and usb[0-1]: filesystem1: options were introduced. format CF-223 Cisco IOS Configuration Fundamentals Command Reference April 2010 • When you specify both arguments—filesystem2: and monlib-filename—the system formats the filesystem1: argument using the monlib file from the specified device. • You can specify the filesystem1: arguments’s own monlib file in this argument. If the system cannot find a monlib file, it terminates its formatting. Note Most platforms do not support booting from images stored on flash memory cards. You should reboot your device only from integrated memory locations, such as NVRAM. Cisco 7600 Series Router Notes The bootflash:, slot0:, sup-slot0:, and sup-bootflash: keywords are supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2. Use the format command to format Class A or C flash memory file systems. • The disk0: and disk1: keywords are for Class C file systems. • The bootflash:, slot0:, sup-slot0:, and sup-bootflash: keywords are for Class A file systems. The disk0: keyword is supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2 only. Cisco ASR 1000 Series Routers Notes This command is available in both privileged EXEC and diagnostic mode on the Cisco ASR1000 Series Routers. Examples The following example shows how to format a flash memory card that is inserted in slot 0: Router# format slot0: Running config file on this device, proceed? [confirm] y All sectors will be erased, proceed? [confirm] y Enter volume id (up to 31 characters): Formatting sector 1 (erasing) Format device slot0 completed When the console returns to the EXEC prompt, the new flash memory card is formatted and ready for use.

If you do not enter the /automatic keyword, command-line interface (CLI) prompts for actions are issued. For the Cisco 7600 series router, if you do not specify the disk0: keyword, the current file system is checked. This command is available in both privileged EXEC and diagnostic mode on the Cisco ASR1000 series routers. Command Modes Privileged EXEC (#) Diagnostic (diag) /nocrc (Optional) This keyword is available for Class C flash file systems only. Omits cyclic redundancy checks (CRCs). /automatic (Optional) This keyword is available for Advanced Technology Attachment (ATA) FAT-based disks only. Specifies that the check and repair actions should proceed automatically. This option can be used to skip the prompts for each check and repair action. Note This command also specifies the automatic mode for the Cisco 7600 series router; see the “Usage Guidelines” section for additional information. /all (Optional) Specifies that all partitions on the disk be checked for problems. /force (Optional) Ensures forced termination of simultaneous file operations on the same device. filesystem: The file system prefix indicating the disk to be checked. The colon (:) is required. Typically, the file system prefix will be disk0: or disk1:. In case of dual processors, the file system on the redundant supervisor engine can also be specified. fsck CF-226 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command History Usage Guidelines Supported Platforms Other than Cisco 7600 Series Router This command performs all steps necessary to remove corrupted files and reclaim unused disk space. Changes include checking for incorrect file sizes, cluster loops, and so on. The default form of this command issues multiple prompts to confirm each of the changes. However, you can skip these prompts by using the /automatic keyword when issuing the command. When you use the /automatic keyword you are prompted to confirm that you want the automatic option. Prompts for actions will be skipped, but all actions performed are displayed to the terminal (see the example below). This command works with ATA Personal Computer Memory Card Industry Association (PCMCIA) cards formatted in Disk Operating System (DOS), or for Class C flash file systems. Note Only one partition (the active partition) is checked in the ATA disk. Cisco 7600 Series Router The disk0: or slavedisk0: file systems are the only file systems in the Cisco 7600 series routers on which you can run the File-System-Check (fsck) utility. The slavedisk0: file system appears in redundant supervisor engine systems only. This command is valid only on Class C flash file systems and only on PCMCIA ATA flash disks and CompactFlash disks. The output for the fsck slavedisk0: command is similar to the fsck disk0: command output. If you do not enter any arguments, the current file system is used. Use the pwd command to display the current file system. Release Modification 11.3 AA This command was introduced. 12.0(22)S This command was implemented on the Cisco 7000 family of routers and on the Cisco 10000 series router and the Gigabit Switch Router (GSR) to support ATA disks. 12.2(13)T This command was integrated into Cisco IOS Release 12.2(13)T. 12.2(14)SX This command was modified.

The /force keyword was added. fsck CF-227 Cisco IOS Configuration Fundamentals Command Reference April 2010 If you enter the disk0: or slavedisk0: keyword, the fsck utility checks the selected file system for problems. If a problem is detected, a prompt is displayed asking if you want the problem fixed. If you enter the /automatic keyword, you are prompted to confirm that you want the automatic mode. In automatic mode, problems are fixed automatically and you are not prompted to confirm. If you do not specify the /force keyword, any simultaneous file operations on the same device are not terminated. Instead, an error message stating files are open for read or write access appears. If you specify the /force keyword, the fsck utility terminates files that are open for read or write access and continues to check for problems. Table 32 lists the checks and actions that are performed by the fsck utility. Table 32 fsck Utility Checks and Actions Checks Actions Checks the boot sector and the partition table and reports the errors. No action. Validates the media with the signature in the last 2 bytes of the first sector (0x55 and 0xaa, respectively). No action. Checks the os_id to find whether this is a FAT-12 or FAT-16 file system (valid values include 0, 1, 4, and 6). No action. Checks the number of FAT’s field (correct values are 1 and 2). No action. Checks these values: • n_fat_sectors cannot be less than 1. • n_root_entries cannot be less than 16. • n_root_sectors cannot be less than 2. • base_fat_sector, n_sectors_per_cluster, n_heads, n_sectors_per_track is not 0. No action. Checks the files and FAT for these errors: Checks the FAT for invalid cluster numbers. If the cluster is a part of a file chain, the cluster is changed to end of file (EOF). If the cluster is not part of a file chain, it is added to the free list and unused cluster chain. Table 33 lists valid cluster numbers; numbers other than those listed in Table 33 are invalid numbers. Checks the file’s cluster chain for loops. If the loop is broken, the file is truncated at the cluster where the looping occurred. Checks the directories for nonzero size fields. If directories are found with nonzero size fields, the size is reset to zero. Checks for invalid start cluster file numbers. If the start cluster number of a file is invalid, the file is deleted. Checks files for bad or free clusters. If the file contains bad or free clusters, the file is truncated at the last good cluster; an example is the cluster that points to this bad/free cluster. Checks to see if the file’s cluster chain is longer than indicated by the size fields. If the file’s cluster chain is longer than indicated by the size fields, the file size is recalculated and the directory entry is updated. fsck CF-228 Cisco IOS Configuration Fundamentals Command Reference April 2010 Table 33 lists the valid cluster numbers.

Defaults No default behavior or values. Command Modes User EXEC Privileged EXEC All configuration modes Command History Usage Guidelines The help command provides a brief description of the context-sensitive help system, which functions as follows: • To list all commands available for a particular command mode, enter a question mark (?) at the system prompt. • To obtain a list of commands that begin with a particular character string, enter the abbreviated command entry immediately followed by a question mark (?). This form of help is called word help, because it lists only the keywords or arguments that begin with the abbreviation you entered. • To list the keywords and arguments associated with a command, enter a question mark (?) in place of a keyword or argument on the command line. This form of help is called command syntax help, because it lists the keywords or arguments that apply based on the command, keywords, and arguments you have already entered. Examples In the following example, the help command is used to display a brief description of the help system: Router# help Help may be requested at any point in a command by entering a question mark '?'. If nothing matches, the help list will be empty and you must backup until entering a '?' shows the available options. Two styles of help are provided: 1. Full help is available when you are ready to enter a command argument (e.g. 'show ?') and describes each possible argument. 2. Partial help is provided when an abbreviated argument is entered Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. help CF-234 Cisco IOS Configuration Fundamentals Command Reference April 2010 and you want to know what arguments match the input (e.g. 'show pr?'.)

Command Description history CF-237 Cisco IOS Configuration Fundamentals Command Reference April 2010 history To enable the command history function, use the history command in line configuration mode. To disable the command history function, use the no form of this command. history no history Syntax Description This command has no arguments or keywords. Defaults Enabled with ten command lines in the buffer. Command Modes Line configuration Command History Usage Guidelines The command history function provides a record of EXEC commands that you have entered. This function is particularly useful for recalling long or complex commands or entries, including access lists. To change the number of command lines that the system will record in its history buffer, use the history size line configuration command. The history command enables the history function with the last buffer size specified or, if there was not a prior setting, with the default of ten lines. The no history command disables the history function. The show history EXEC command will list the commands you have entered, but you can also use your keyboard to display individual commands. Table 34 lists the keys you can use to recall commands from the command history buffer. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Table 34 History Keys Key(s) Functions Ctrl-P or Up Arrow1 1. The arrow keys function only with ANSI-compatible terminals. Recalls commands in the history buffer in a backward sequence, beginning with the most recent command.

Repeat the key sequence to recall successively more recent commands. history CF-238 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples In the following example, the command history function is disabled on line 4: Router(config)# line 4 Router(config-line)# no history Related Commands Command Description history size Sets the command history buffer size for a particular line. show history Lists the commands you have entered in the current EXEC session. terminal history Enables the command history function for the current terminal session or changes the size of the command history buffer for the current terminal session. history size CF-239 Cisco IOS Configuration Fundamentals Command Reference April 2010 history size To change the command history buffer size for a particular line, use the history size command in line configuration mode. To reset the command history buffer size to ten lines, use the no form of this command. history size number-of-lines no history size Syntax Description Defaults 10 command lines Command Modes Line configuration Command History Usage Guidelines The history size command should be used in conjunction with the history and show history commands. The history command enables or disables the command history function. The show history command lists the commands you have entered in the current EXEC session. The number of commands that the history buffer will show is set by the history size command. Note The history size command only sets the size of the buffer; it does not reenable the history function. If the no history command is used, the history command must be used to reenable this function. Examples The following example displays line 4 configured with a history buffer size of 35 lines: Router(config)# line 4 Router(config-line)# history size 35 Related Commands number-of-lines Specifies the number of command lines that the system will record in its history buffer. The range is from 0 to 256. The default is 10. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

To restore the default, use the no form of this command. hold-character ascii-number no hold-character Syntax Description Defaults No hold character is defined. Command Modes Line configuration Command History Usage Guidelines The Break character is represented by zero; NULL cannot be represented. To continue the output, enter any character after the hold character. To use the hold character in normal communications, precede it with the escape character. See the “ASCII Character Set” appendix for a list of ASCII characters. Examples The following example sets the hold character to Ctrl-S, which is ASCII decimal character 19: Router(config)# line 8 Router(config-line)# hold-character 19 Related Commands ascii-number ASCII decimal representation of a character or control sequence (for example, Ctrl-P). Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description terminal hold-character Sets or changes the hold character for the current session. hostname CF-241 Cisco IOS Configuration Fundamentals Command Reference April 2010 hostname To specify or modify the host name for the network server, use the hostname command in global configuration mode. hostname name Syntax Description Command Default The default host name is Router. Command Modes Global configuration Command History Usage Guidelines The host name is used in prompts and default configuration filenames. Do not expect case to be preserved. Uppercase and lowercase characters look the same to many internet software applications. It may seem appropriate to capitalize a name the same way you might do in English, but conventions dictate that computer names appear all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer. The name must also follow the rules for ARPANET host names. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphens. Names must be 63 characters or fewer. A host name of less than 10 characters is recommended. For more information, refer to RFC 1035, Domain Names—Implementation and Specification. On most systems, a field of 30 characters is used for the host name and the prompt in the CLI. Note that the length of your host name may cause longer configuration mode prompts to be truncated. For example, the full prompt for service profile configuration mode is: (config-service-profile)# However, if you are using the host-name of "Router", you will only see the following prompt (on most systems): Router(config-service-profil)# If the hostname is longer, you will see even less of the prompt: Basement-rtr2(config-service)# Keep this behavior in mind when assigning a name to your system (using the hostname global configuration command). If you expect that users will be relying on mode prompts as a CLI navigation aid, you should assign host names of no more than nine characters. name New host name for the network server.

To disable BOOTP services, use the no form of the command. ip bootp server no ip bootp server Syntax Description This command has no arguments or keywords. Defaults Enabled Command Modes Global configuration Command History Usage Guidelines By default, the BOOTP service is enabled. When disabled, the no ip bootp server command will appear in the configuration file. The integrated Dynamic Host Configuration Protocol (DHCP) server was introduced in Cisco IOS Release 12.0(1)T. Because DHCP is based on BOOTP, both of these services share the “well-known” UDP server port of 67 (per RFC 951, RFC 1534, and RFC 2131; the client port is 68). To disable DHCP services (DHCP relay and DHCP server), use the no service dhcp command. To disable BOOTP services (in releases 12.2(8)T and later), but leave DHCP services enabled, use the ip dhcp bootp ignore command. If both the BOOTP server and DHCP server are disabled, “ICMP port unreachable” messages will be sent in response to incoming requests on port 67, and the original incoming packet will be discarded. If DHCP is enabled, using the no ip bootp server command by itself will not stop the router from listening on UDP port 67. Note As with all minor services, the async line BOOTP service should be disabled on your system if you do not have a need for it in your network. Any network device that has User Data Protocol (UDP), TCP, BOOTP, DHCP, or Finger services should be protected by a firewall or have the services disabled to protect against Denial of Service attacks. Release Modification 11.2 This command was introduced. 12.0(1)T The DHCP relay agent and DHCP server features were introduced. BOOTP forwarding is now handled by the DHCP relay agent implementation. 12.2(8)T The ip dhcp bootp ignore command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip bootp server CF-248 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples In the following example, BOOTP and DHCP services are disabled on the router: Router(config)# no ip bootp server Router(config)# no service dhcp Related Commands Command Description ip dhcp bootp ignore Configures the Cisco IOS DHCP server to selectively ignore and not reply to received Bootstrap Protocol (BOOTP) request packets, allowing you continue using DHCP while disabling BOOTP. service dhcp Enables the Cisco IOS Dynamic Host Configuration Protocol (DHCP) server and relay agent features. ip finger CF-249 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip finger To configure a system to accept Finger protocol requests (defined in RFC 742), use the ip finger command in global configuration mode. To disable this service, use the no form of this command. ip finger [rfc-compliant] no ip finger Syntax Description Defaults Disabled Command Modes Global configuration Command History Usage Guidelines The Finger service allows remote users to view the output equivalent to the show users [wide] command. When ip finger is configured, the router will respond to a telnet a.b.c.d finger command from a remote host by immediately displaying the output of the show users command and then closing the connection. When the ip finger rfc-compliant command is configured, the router will wait for input before displaying anything (as required by RFC 1288). The remote user can then enter the Return key to display the output of the show users EXEC command, or enter /W to display the output of the show users wide EXEC command. After this information is displayed, the connection is closed. Note As with all minor services, the Finger service should be disabled on your system if you do not have a need for it in your network. Any network device that has UDP, TCP, BOOTP, or Finger services should be protected by a firewall or have the services disabled to protect against Denial of Service attacks. Because of the potential for hung lines, the rfc-compliant form of this command should not be configured for devices with more than 20 simultaneous users. rfc-compliant (Optional) Configures the system to wait for “Return” or “/W” input when processing Finger requests. This keyword should not be used for those systems.

To use the address of the interface where the connection is made, use the no form of this command. ip ftp source-interface interface-type interface-number no ip ftp source-interface Syntax Description Command Default The FTP source address is the IP address of the interface that the FTP packets use to leave the router. Command Modes Global configuration (config) Command History Usage Guidelines Use this command to set the same source address for all FTP connections. In Cisco IOS 12.3(6) and later releases, FTP is VRF-aware, which means that FTP transfer is supported across an interface within a VRF instance. To specify a VRF as a source for FTP connections, the VRF must be associated with the same interface that you configure with the ip ftp source-interface command. In this configuration, FTP looks for the destination IP address for file transfer in the specified VRF table. If the specified source interface is not up, Cisco IOS software selects the address of the interface closest to the destination as the source address. Examples The following example shows how to configure the router to use the IP address associated with Ethernet interface 0 as the source address on all FTP packets, regardless of which interface is actually used to send the packet: Router> enable Router# configure terminal Router(config)# ip ftp source-interface ethernet 0 The following example shows how to configure the router to use the VRF table named vpn1 to look for the destination IP address for the transfer of FTP packets: interface-type interface-number The interface type and number to use to obtain the source address for FTP connections.

To restore the interface to the default of no RARP server support, use the no form of this command. ip rarp-server ip-address no ip rarp-server ip-address Syntax Description Defaults Disabled Command Modes Interface configuration Command History Usage Guidelines This feature makes diskless booting of clients possible between network subnets where the client and server are on separate subnets. RARP server support is configurable on a per-interface basis, so that the router does not interfere with RARP traffic on subnets that need no RARP assistance. The Cisco IOS software answers incoming RARP requests only if both of the following two conditions are met: • The ip rarp-server command has been configured for the interface on which the request was received. • A static entry is found in the IP ARP table that maps the MAC address contained in the RARP request to an IP address. Use the show ip arp EXEC command to display the contents of the IP ARP cache. Sun Microsystems, Inc. makes use of RARP and UDP-based network services to facilitate network-based booting of SunOS on it’s workstations. By bridging RARP packets and using both the ip helper-address interface configuration command and the ip forward-protocol global configuration command, the Cisco IOS software should be able to perform the necessary packet switching to enable booting of Sun workstations across subnets. Unfortunately, some Sun workstations assume that the sender of the RARP response, in this case the router, is the host that the client can contact to TFTP load the bootstrap image. This causes the workstations to fail to boot. ip-address IP address that is to be provided in the source protocol address field of the RARP response packet. Normally, this is set to whatever address you configure as the primary address for the interface. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip rarp-server CF-257 Cisco IOS Configuration Fundamentals Command Reference April 2010 By using the ip rarp-server command, the Cisco IOS software can be configured to answer these RARP requests, and the client machine should be able to reach its server by having its TFTP requests forwarded through the router that acts as the RARP server. In the case of RARP responses to Sun workstations attempting to diskless boot, the IP address specified in the ip rarp-server interface configuration command should be the IP address of the TFTP server. In addition to configuring RARP service, the Cisco IOS software must be configured to forward UDP-based Sun portmapper requests to completely support diskless booting of Sun workstations. This can be accomplished using configuration commands of the following form: ip forward-protocol udp 111 interface interface name ip helper-address target-address RFC 903 documents the RARP. Examples The following partial example configures a router to act as a RARP server. The router is configured to use the primary address of the specified interface in its RARP responses. arp 172.30.2.5 0800.2002.ff5b arpa interface ethernet 0 ip address 172.30.3.100 255.255.255.0 ip rarp-server 172.30.3.100 In the following example, a router is configured to act as a RARP server, with TFTP and portmapper requests forwarded to the Sun server: ! Allow the router to forward broadcast portmapper requests ip forward-protocol udp 111 ! Provide the router with the IP address of the diskless sun arp 172.30.2.5 0800.2002.ff5b arpa interface ethernet 0 ! Configure the router to act as a RARP server, using the Sun Server's IP ! address in the RARP response packet. ip rarp-server 172.30.3.100 ! Portmapper broadcasts from this interface are sent to the Sun Server. ip helper-address 172.30.3.100 Related Commands Command Description ip forward-protocol Speeds up flooding of UDP datagrams using the spanning-tree algorithm. ip helper-address Forwards UDP broadcasts, including BOOTP, received on an interface. ip rcmd domain-lookup CF-258 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip rcmd domain-lookup To reenable the basic Domain Name Service (DNS) security check for rcp and rsh, use the ip rcmd domain-lookup command in global configuration mode. To disable the basic DNS security check for remote copy protocol (rcp) and remote shell protoco (rsh), use the no form of this command. ip rcmd domain-lookup no ip rcmd domain-lookup Syntax Description This command has no arguments or keywords. Defaults Enabled Command Modes Global configuration Command History Usage Guidelines The abbreviation RCMD (remote command) is used to indicate both rsh and rcp. DNS lookup for RCMD is enabled by default (provided general DNS services are enabled on the system using the ip domain-lookup command). The no ip rcmd domain-lookup command is used to disable the DNS lookup for RCMD. The ip rcmd domain-lookup command is used to reenable the DNS lookup for RCMD. DNS lookup for RCMD is performed as a basic security check. This check is performed using a host authentication process. When enabled, the system records the address of the requesting client. That address is mapped to a host name using DNS. Then a DNS request is made for the IP address for that host name. The IP address received is then checked against the original requesting address. If the address does not match with any of the addresses received from DNS, the RCMD request will not be serviced. This reverse lookup is intended to help protect against spoofing. However, please note that the process only confirms that the IP address is a valid “routable” address; it is still possible for a hacker to spoof the valid IP address of a known host. The DNS lookup is done after the TCP handshake but before the router (which is acting as a rsh/rcp server) sends any data to the remote client. The no ip rcmd domain-lookup will turn off DNS lookups for rsh and rcp only. The no ip domain-lookup command takes precedence over the ip rcmd domain-lookup command. This means that if the no ip domain-lookup command is in the current configuration, DNS will be bypassed for rcp and rsh even if the ip rcmd domain-lookup command is enabled.

To disable rcp on the device, use the no form of this command. ip rcmd rcp-enable no ip rcmd rcp-enable Syntax Description This command has no arguments or keywords. Defaults To ensure security, the router is not enabled for rcp by default. Command Modes Global configuration Command History Usage Guidelines To allow a remote user to execute rcp commands on the router, you must also create an entry for the remote user in the local authentication database using the ip rcmd remote-host command. The no ip rcmd rcp-enable command does not prohibit a local user from using rcp to copy system images and configuration files to and from the router. To protect against unauthorized users copying the system image or configuration files, the router is not enabled for rcp by default. Examples In the following example, the rcp service is enabled on the system, the IP address assigned to the Loopback0 interface is used as the source address for outbound rcp and rsh packets, and access is granted to the user “netadmin3”on the remote host 172.16.101.101: Router(config)# ip rcmd rcp-enable Router(config)# ip rcmd source-interface Loopback0 Router(config)# ip rcmd remote-host router1 172.16.101.101 netadmin3 Related Commands Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description ip rcmd remote-host Creates an entry for the remote user in a local authentication database so that remote users can execute commands on the router using rsh or rcp. ip rcmd remote-host CF-261 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip rcmd remote-host To create an entry for the remote user in a local authentication database so that remote users can execute commands on the router using remote shell protocol (rsh) or remote copy protocol (rcp), use the ip rcmd remote-host command in global configuration mode. To remove an entry for a remote user from the local authentication database, use the no form of this command. ip rcmd remote-host local-username {ip-address | host-name} remote-username [enable [level]] no ip rcmd remote-host local-username {ip-address | host-name} remote-username [enable [level]] Syntax Description Defaults No entries are in the local authentication database. Command Modes Global configuration Command History Usage Guidelines A TCP connection to a router is established using an IP address. Using the host name is valid only when you are initiating an rcp or rsh command from a local router. The host name is converted to an IP address using DNS or host-name aliasing. local-username Name of the user on the local router. You can specify the router name as the username. This name needs to be communicated to the network administrator or to the user on the remote system. To be allowed to remotely execute commands on the router, the remote user must specify this value correctly. ip-address IP address of the remote host from which the local router will accept remotely executed commands. Either the IP address or the host name is required. host-name Name of the remote host from which the local router will accept remotely executed commands. Either the host name or the IP address is required. remote-username Name of the user on the remote host from which the router will accept remotely executed commands. enable [level] (Optional) Enables the remote user to execute privileged EXEC commands using rsh or to copy files to the router using rcp. The range is from 1 to 15. The default is 15. For information on the enable level, refer to the privilege level global configuration command in the Release 12.2 Cisco IOS Security Command Reference. Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip rcmd remote-host CF-262 Cisco IOS Configuration Fundamentals Command Reference April 2010 To allow a remote user to execute rcp or rsh commands on a local router, you must create an entry for the remote user in the local authentication database. You must also enable the router to act as an rsh or rcp server. To enable the router to act as an rsh server, issue the ip rcmd rsh-enable command. To enable the router to act as an rcp server, issue the ip rcmd rcp-enable command.The router cannot act as a server for either of these protocols unless you explicitly enable the capacity. A local authentication database, which is similar to a UNIX .rhosts file, is used to enforce security on the router through access control. Each entry that you configure in the authentication database identifies the local user, the remote host, and the remote user. To permit a remote user of rsh to execute commands in privileged EXEC mode or to permit a remote user of rcp to copy files to the router, specify the enable keyword and level. For information on the enable level, refer to the privilege level global configuration command in the Release 12.2 Cisco IOS Security Command Reference. An entry that you configure in the authentication database differs from an entry in a UNIX .rhosts file in the following aspect. Because the .rhosts file on a UNIX system resides in the home directory of a local user account, an entry in a UNIX .rhosts file need not include the local username; the local username is determined from the user account. To provide equivalent support on a router, specify the local username along with the remote host and remote username in each authentication database entry that you configure. For a remote user to be able to execute commands on the router in its capacity as a server, the local username, host address or name, and remote username sent with the remote client request must match values configured in an entry in the local authentication file. A remote client host should be registered with DNS. The Cisco IOS software uses DNS to authenticate the remote host’s name and address. Because DNS can return several valid IP addresses for a host name, the Cisco IOS software checks the address of the requesting client against all of the IP addresses for the named host returned by DNS. If the address sent by the requester is considered invalid, that is, it does not match any address listed with DNS for the host name, then the software will reject the remote-command execution request. Note that if no DNS servers are configured for the router, then that device cannot authenticate the host in this manner. In this case, the Cisco IOS software sends a broadcast request to attempt to gain access to DNS services on another server. If DNS services are not available, you must use the no ip domain-lookup command to disable the attempt to gain access to a DNS server by sending a broadcast request. If DNS services are not available and, therefore, you bypass the DNS security check, the software will accept the request to remotely execute a command only if all three values sent with the request match exactly the values configured for an entry in the local authentication file. Examples The following example allows the remote user named netadmin3 on a remote host with the IP address 172.16.101.101 to execute commands on router1 using the rsh or rcp protocol. User netadmin3 is allowed to execute commands in privileged EXEC mode. Router(config)# ip rcmd remote-host router1 172.16.101.101 netadmin3 enable Related Commands Command Description ip rcmd rcp-enable Configures the Cisco IOS software to allow remote users to copy files to and from the router. ip rcmd remote-host CF-263 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip domain-lookup Enables the IP DNS-based host name-to-address translation. ip rcmd rsh-enable Configures the router to allow remote users to execute commands on it using the rsh protocol. Command Description ip rcmd remote-username CF-264 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip rcmd remote-username To configure the remote username to be used when requesting a remote copy using remote copy protocol (rcp), use the ip rcmd remote-username command in global configuration mode. To remove from the configuration the remote username, use the no form of this command. ip rcmd remote-username username no ip rcmd remote-username username Syntax Description Defaults If you do not issue this command, the Cisco IOS software sends the remote username associated with the current tty process, if that name is valid, for rcp copy commands. For example, if the user is connected to the router through Telnet and the user was authenticated through the username command, then the software sends that username as the remote username. Note The remote username must be associated with an account on the destination server. If the username for the current tty process is not valid, the Cisco IOS software sends the host name as the remote username. For rcp boot commands, the Cisco IOS software sends the access server host name by default. Note For Cisco, tty lines are commonly used for access services. The concept of tty originated with UNIX. For UNIX systems, each physical device is represented in the file system. Terminals are called tty devices (tty stands for teletype, the original UNIX terminal). Command Modes Global configuration Command History Usage Guidelines The rcp protocol requires that a client send the remote username on an rcp request to the server. Use this command to specify the remote username to be sent to the server for an rcp copy request. If the server has a directory structure, as do UNIX systems, all files and images to be copied are searched for or written relative to the directory of the remote user’s account. username Name of the remote user on the server. This name is used for rcp copy requests. All files and images to be copied are searched for or written relative to the directory of the remote user’s account, if the server has a directory structure, for example, as do UNIX systems. Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip rcmd remote-username CF-265 Cisco IOS Configuration Fundamentals Command Reference April 2010 Note Cisco IOS Release 10.3 added the ip keyword to rcmd commands. If you are upgrading from Release 10.2 to Release 10.3 or a later release, this keyword is automatically added to any rcmd commands you have in your Release 10.2 configuration files. Examples The following example configures the remote username to netadmin1: Router(config)# ip rcmd remote-username netadmin1 Related Commands Command Description boot network rcp Changes the default name of the network configuration file from which to load configuration commands. boot system rcp Specifies the system image that the router loads at startup. bridge acquire Forwards any frames for stations that the system has learned about dynamically. copy Copies any file from a source to a destination. ip rcmd rsh-enable CF-266 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip rcmd rsh-enable To configure the router to allow remote users to execute commands on it using remote shell protocol (rsh), use the ip rcmd rsh-enable command in global configuration mode. To disable a router that is enabled for rsh, use the no form of this command. ip rcmd rsh-enable no ip rcmd rsh-enable Syntax Description This command has no arguments or keywords. Defaults To ensure security, the router is not enabled for rsh by default. Command Modes Global configuration Command History Usage Guidelines rsh, used as a client process, gives users the ability to remotely get router information (such as status) without the need to connect into the router and then disconnect. This is valuable when looking at many statistics on many different routers. Use this command to enable the router to receive rsh requests from remote users. In addition to issuing this command, you must create an entry for the remote user in the local authentication database to allow a remote user to execute rsh commands on the router. The no ip rcmd rsh-enable command does not prohibit a local user of the router from executing a command on other routers and UNIX hosts on the network using rsh. The no form of this command only disables remote access to rsh on the router. Examples The following example enables a router as an rsh server: Router(config)# ip rcmd rsh-enable Related Commands Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description ip rcmd remote-host Creates an entry for the remote user in a local authentication database so that remote users can execute commands on the router using rsh or rcp. ip rcmd source-interface CF-267 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip rcmd source-interface To force remote copy protocol (rcp) or remote shell protocol (rsh) to use the IP address of a specified interface for all outgoing rcp/rsh communication packets, use the ip rcmd source-interface command in global configuration mode. To disable a previously configured ip rcmd source-interface command, use the no form of this command. ip rcmd source-interface interface-id no ip rcmd source-interface interface-id Syntax Description Defaults The address of the interface closest to the destination is used as the source interface for rcp/rsh communications. Command Modes Global configuration Command History Usage Guidelines If this command is not used, or if the interface specified in this command is not available (not up), the Cisco IOS software uses the address of the interface closest to the destination as the source address. Use this command to force the system to tag all outgoing rcp/rsh packets with the IP address associated with the specified interface. This address is used as the source address as long as the interface is in the up state. This command is especially useful in cases where the router has many interfaces, and you want to ensure that all rcp and/or rsh packets from this router have the same source IP address. A consistent address is preferred so that the other end of the connection (the rcp/rsh server or client) can maintain a single session. The other benefit of a consistent address is that an access list can be configured on the remote device. The specified interface must have an IP address associated with it. If the specified interface does not have an IP address or is in a down state, then rcp/rsh reverts to the default. To avoid this, add an IP address to the subinterface or bring the interface to the up state. Examples In the following example, Loopback interface 0 is assigned an IP address of 220.144.159.200, and the ip rcmd source-interface command is used to specify that the source IP address for all rcp/rsh packets will be the IP address assigned to the Loopback0 interface: interface Loopback0 interface-id The name and number used to identify the interface. For example, Loopback2.

Command Modes Global configuration Command History Usage Guidelines Use this command to set the IP address of an interface as the source for all Telnet connections. If the specified interface is not up, the Cisco IOS software selects the address of the interface closest to the destination as the source address. Examples The following example forces the IP address for Ethernet interface 1 as the source address for Telnet connections: Router(config)# ip telnet source-interface Ethernet1 Related Commands interface The interface whose address is to be used as the source for Telnet connections.

Command Description ip radius source-interface Forces RADIUS to use the IP address of a specified interface for all outgoing RADIUS packets. ip tftp source-interface CF-270 Cisco IOS Configuration Fundamentals Command Reference April 2010 ip tftp source-interface To specify the IP address of an interface as the source address for TFTP connections, use the ip tftp source-interface command in global configuration mode. To return to the default, use the no form of this command. ip tftp source-interface interface-type interface-number no ip tftp source-interface Syntax Description Command Default The address of the closest interface to the destination is selected as the source address. Command Modes Global configuration Command History Usage Guidelines Use this command to set the IP address of an interface as the source for all TFTP connections. If the specified interface is not up, the Cisco IOS software selects the address of the interface closest to the destination as the source address. In Cisco IOS 12.3(6) and later releases, TFTP is VRF-aware, which means that TFTP transfer is supported across an interface within a Virtual Private Network (VPN) routing and forwarding (VRF) instance. To specify a VRF as a source for TFTP connections, the VRF must be associated with the same interface that you configure with the ip tftp source-interface command. In this configuration, TFTP looks for the destination IP address for file transfer in the specified VRF table. Examples The following example shows how to configure the router to use the IP address associated with loopback interface 0 as the source address for TFTP connections: configure terminal ! ip tftp source-interface loopback0 The following example shows how to configure the router to use the VRF table named vpn1 to look for the destination IP address for TFTP connections: interface-type interface-number The interface type and number whose address is to be used as the source for TFTP connections. Release Modification 11.1 This command was introduced. 12.3(6) Destination address lookup in a Virtual Private Network (VPN) routing and forwarding (VRF) table was added for the transfer of TFTP packets. 12.3(8)T This command was integrated into Cisco IOS Release 12.3(8)T. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip tftp source-interface CF-271 Cisco IOS Configuration Fundamentals Command Reference April 2010 configure terminal ! ip tftp source-interface ethernet 1/0 ! ip vrf vpn1 rd 100:1 route-target both 100:1 ! interface ethernet 1/0 ip vrf forwarding vpn1 end In this example, file transfer using TFTP is accomplished across an interface within a VRF (VRF vpn1) link.

To disable hardware acceleration, use the no form of this command. ip wccp web-cache accelerated [[group-address groupaddress] | [redirect-list access-list] | [group-list access-list] | [password password]] no ip wccp web-cache accelerated Syntax Description Defaults Disabled Command Modes Global configuration (config) Command History Usage Guidelines This command is supported on software releases later than cache engine software Release ACNS 4.2.1. The group-address group-address option requires a multicast address that is used by the router to determine which cache engine should receive redirected messages. This option instructs the router to use the specified multicast IP address to coalesce the “I See You” responses for the “Here I Am” messages that it has received on this group address. In addition, the response is sent to the group address. The default is for no group-address to be configured, so that all “Here I Am” messages are responded to with a unicast reply. group-address group-address (Optional) Directs the router to use a specified multicast IP address for communication with the WCCP service group. See the “Usage Guidelines” section for additional information. redirect-list access-list (Optional) Directs the router to use an access list to control traffic that is redirected to this service group. See the “Usage Guidelines” section for additional information. group-list access-list (Optional) Directs the router to use an access list to determine which cache engines are allowed to participate in the service group. See the “Usage Guidelines” section for additional information. password password (Optional) Specifies a string that directs the router to apply MD5 authentication to messages received from the service group specified by the service name given. See the “Usage Guidelines” section for additional information. Release Modification 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Cisco IOS Release 12.2(17d)SXB. 12.2(18)SXD1 This command was changed to support the Supervisor Engine 720. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. ip wccp web-cache accelerated CF-273 Cisco IOS Configuration Fundamentals Command Reference April 2010 The redirect-list access-list option instructs the router to use an access list to control the traffic that is redirected to the cache engines of the service group that is specified by the service-name given. The access-list argument specifies either a number from 1 to 99 to represent a standard or extended access-list number, or a name to represent a named standard or extended access list. The access list itself specifies the traffic that is permitted to be redirected. The default is for no redirect-list to be configured (all traffic is redirected). The group-list access-list option instructs the router to use an access list to control the cache engines that are allowed to participate in the specified service group. The access-list argument specifies either a number from 1 to 99 to represent a standard access-list number, or a name to represent a named standard access list. The access list specifies which cache engines are permitted to participate in the service group. The default is for no group-list to be configured, so that all cache engines may participate in the service group. The password can be up to seven characters. When you designate a password, the messages that are not accepted by the authentication are discarded. The password name is combined with the HMAC MD5 value to create security for the connection between the router and the cache engine.

To restore the default value, use the no form of this command. length screen-length no length Syntax Description Defaults Screen length of 24 lines Command Modes Line configuration Command History Usage Guidelines The Cisco IOS software uses the value of this command to determine when to pause during multiple-screen output. Not all commands recognize the configured screen length. For example, the show terminal command assumes a screen length of 24 lines or more. Examples In the following example, the terminal type is specified and the screen pause function is disabled for the terminal connection on line 6: Router(config)# line 6 Router(config-line)# terminal-type VT220 Router(config-line)# length 0 Related Commands screen-length The number of lines on the screen. A value of zero disables pausing between screens of output. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description terminal length Sets the number of lines on the current terminal screen for the current session. load-interval CF-275 Cisco IOS Configuration Fundamentals Command Reference April 2010 load-interval To change the length of time for which data is used to compute load statistics, use the load-interval command in interface configuration mode or Frame Relay DLCI configuration mode. To revert to the default setting, use the no form of this command. load-interval seconds no load-interval seconds Syntax Description Command Default Enabled Command Modes Interface configuration Frame Relay DLCI configuration Command History Usage Guidelines To make computations more reactive to short bursts of traffic, you can shorten the length of time over which load averages are computed. If the load interval is set to 30 seconds, new data is used for load calculations over a 30-second period. This data is used to compute load statistics, including the input rate in bits and packets per second, the output rate in bits and packets per second, the load, and reliability. Load data is gathered every five seconds. This data is used for a weighted-average calculation in which recent load data has more weight in the computation than older load data. If the load interval is set to 30 seconds, the average is computed for the last 30 seconds of load data. If you change the calculation interval from the default of five minutes to a shorter period of time, the input and output statistics that are displayed by the show interface command or the show frame-relay pvc command will be more current and will be based on more nearly instantaneous data, rather than reflecting the average load over a longer period of time. This command is often used for dial backup purposes to increase or decrease the likelihood of implementation of a backup interface, but it can be used on any interface. seconds Length of time for which data is used to compute load statistics. Value is a multiple of 30, from 30 to 600 (30, 60, 90, 120, and so on). The default is 300 seconds.

Defaults Not locked Command Modes EXEC Command History Usage Guidelines You can prevent access to your session while keeping your connection open by setting up a temporary password. To lock access to the terminal, perform the following steps: Step 1 Enter the lock command. The system prompts you for a password. Step 2 Enter a password, which can be any arbitrary string. The system will prompt you to confirm the password. The screen then clears and displays the message “Locked.” Step 3 To regain access to your sessions, reenter the password. The Cisco IOS software honors session timeouts on a locked lines. You must clear the line to remove this feature. The system administrator must set the line up to allow use of the temporary locking feature by using the lockable line configuration command.

To disable synchronization of unsolicited messages and debug output, use the no form of this command. logging synchronous [level severity-level | all] [limit number-of-lines] no logging synchronous [level severity-level | all] [limit number-of-lines] Syntax Description Defaults This command is disabled. If you do not specify a severity level, the default value of 2 is assumed. If you do not specify the maximum number of buffers to be queued, the default value of 20 is assumed. Command Modes Line configuration Command History Usage Guidelines When synchronous logging of unsolicited messages and debug output is turned on, unsolicited Cisco IOS software output is displayed on the console or printed after solicited Cisco IOS software output is displayed or printed. This keeps unsolicited messages and debug output from being interspersed with solicited software output and prompts. Tip This command is useful for keeping system messages from interrupting your typing. By default, messages will appear immediately when they are processed by the system, and the CLI cursor will appear at the end of the displayed message. For example, the line “Configured by console from console” level severity-level (Optional) Specifies the message severity level. Messages with a severity level equal to or higher than this value are printed asynchronously. Low numbers indicate greater severity and high numbers indicate lesser severity. The default value is 2. all (Optional) Specifies that all messages are printed asynchronously, regardless of the severity level. limit number-of-lines (Optional) Specifies the number of buffer lines to be queued for the terminal, after which new messages are dropped. The default value is 20. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2SX This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware. logging synchronous CF-302 Cisco IOS Configuration Fundamentals Command Reference April 2010 may be printed to the screen, interrupting whatever command you are currently typing. The logging synchronous command allows you to avoid these potentially annoying interruptions without have to turn off logging to the console entirely. When this command is enabled, unsolicited messages and debug output are displayed on a separate line than user input. After the unsolicited messages are displayed, the CLI returns to the user prompt. Note This command is also useful for allowing you to continue typing when debugging is enabled. When specifying a severity level number, consider that for the logging system, low numbers indicate greater severity and high numbers indicate lesser severity. When a message queue limit of a terminal line is reached, new messages are dropped from the line, although these messages might be displayed on other lines. If messages are dropped, the notice “%SYS-3-MSGLOST number-of-messages due to overflow” follows any messages that are displayed. This notice is displayed only on the terminal that lost the messages. It is not sent to any other lines, any logging servers, or the logging buffer. Caution By configuring abnormally large message queue limits and setting the terminal to “terminal monitor” on a terminal that is accessible to intruders, you expose yourself to “denial of service” attacks. An intruder could carry out the attack by putting the terminal in synchronous output mode, making a Telnet connection to a remote host, and leaving the connection idle. This could cause large numbers of messages to be generated and queued, and these messages could consume all available RAM. You should guard against this type of attack through proper configuration. Examples In the following example, a system message appears in the middle of typing the show running-config command: Router(config-line)# end Router# show ru 2w1d: %SYS-5-CONFIG_I: Configured from console by consolenning-config . . . The user then enables synchronous logging for the current line (indicated by the * symbol in the show line command), after which the system displays the system message on a separate line, and returns the user to the prompt to allow the user to finish typing the command on a single line: Router# show line Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int * 0 CTY - - - - - 0 3 0/0 - . . . Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z.

Then synchronous logging for line 2 is enabled with a severity level of 7 and is specified with a maximum number of buffer lines of 1,000. Router(config)# line 4 Router(config-line)# logging synchronous level 6 Router(config-line)# exit Router(config)# line 2 Router(config-line)# logging synchronous level 7 limit 1000 Router(config-line)# end Router# Related Commands Command Description line Identifies a specific line for configuration and starts the line configuration command collection mode. logging on Controls logging of error messages and sends debug or error messages to a logging process, which logs messages to designated locations asynchronously to the processes that generated the messages. logging system CF-304 Cisco IOS Configuration Fundamentals Command Reference April 2010 logging system To enable System Event Archive (SEA) logging, use the logging system command in global configuration mode.

To disable memory threshold notifications, use the no form of this command. memory free low-watermark {processor threshold | io threshold} no memory free low-watermark Syntax Description Defaults Memory threshold notifications are disabled. Command Modes Global configuration Command History Usage Guidelines Using this command, you can configure a router to issue a system logging message each time available free memory falls below a specified threshold (“low-watermark”). Once available free memory rises to 5 percent above the threshold, another notification message is generated. Examples The following example specifies a free processor memory notification threshold of 20000 KB: Router(config)# memory free low-watermark processor 200000 If available free processor memory falls below this threshold, the router sends a notification message like this one: 000029: *Aug 12 22:31:19.559: %SYS-4-FREEMEMLOW: Free Memory has dropped below 20000k Pool: Processor Free: 66814056 freemem_lwm: 204800000 Once available free processor memory rises to a point 5 percent above the threshold, another notification message like this is sent: processor threshold Sets the processor memory threshold in kilobytes. When available processor memory falls below this threshold, a notification message is triggered. Valid values are 1 to 4294967295. io threshold Sets the input/output (I/O) memory threshold in kilobytes. When available I/O memory falls below this threshold, a notification message is triggered.

See the memory reserve command for more information. To configure the size of the memory region to be used for critical notifications (system logging messages), use the memory reserve critical command in global configuration mode. To disable the reservation of memory for critical notifications, use the no form of this command. memory reserve critical kilobytes no memory reserve critical Syntax Description Defaults 100 kilobytes of memory is reserved for the logging process. Command Modes Global configuration (config) Command History Usage Guidelines This command reserves a region of memory on the router so that, when system resources are overloaded, the router retains enough memory to issue critical system logging messages. Note Once the size of the reserved memory region is specified, any change to the specified value takes effect only after the current configuration is saved and the system has been reloaded. Examples The following example shows how to reserve 1,000 KB of system memory for logging messages at the next system restart: Router(config)# memory reserve critical 1000 kilobytes Specifies the amount of memory to be reserved in kilobytes. Valid values are 1 to 4294967295, but the value you specify cannot exceed 25 percent of total memory. The default is 100 kilobytes.

To disable this feature, use the no form of this command. memory sanity [buffer | queue | all] no memory sanity Syntax Description Defaults This command is not enabled by default. If the buffer or queue keyword is not specified, a sanity check will be performed on all buffers and queues. Command Modes Global configuration Command History Usage Guidelines When the memory sanity buffer command is enabled, a sanity check is performed on buffers when a packet buffer is allocated or when a packet buffer is returned to the buffer pool. This command also time-stamps the buffer, which may be useful when tracking the age of a buffer. The memory sanity command can be saved in the startup configuration file and, therefore, it is not necessary to reconfigure this command each time the router is reloaded. Like the scheduler heapcheck process memory command, the memory sanity command can check for corruption in the I/O memory block. Enabling the memory sanity command may result in slight router performance degradation. Examples The following example shows how to perform a sanity check for corruption in all buffers and queues: memory sanity all Related Commands buffer (Optional) Specifies checking all buffers. queue (Optional) Specifies checking all queues. all (Optional) Specifies checking all buffers and queues. Release Modification 12.2(15)T This command was introduced. Command Description scheduler heapcheck process memory Performs a “sanity check” for corruption in memory blocks when a process switch occurs. memory scan CF-319 Cisco IOS Configuration Fundamentals Command Reference April 2010 memory scan To enable the Memory Scan feature, use the memory scan command in global configuration mode. To restore the router configuration to the default, use the no form of this command. memory scan no memory scan Syntax Description This command has no arguments or keywords. Defaults This command is disabled by default. Command Modes Global configuration Command History Usage Guidelines The Memory Scan feature adds a low-priority background process that searches all installed dynamic random-access memory (DRAM) for possible parity errors. If errors are found in memory areas that are not in use, this feature attempts to scrub (remove) the errors. The time to complete one memory scan and scrub cycle can range from 10 minutes to several hours, depending on the amount of installed memory. The impact of the Memory Scan feature on the central processing unit (CPU) is minimal. To view the status of the memory scan feature on your router, use the show memory scan command in EXEC mode. Examples The following example enables the Memory Scan feature on a Cisco 7500 series router: Router(config)# memory scan Related Commands Release Modification 12.0(4)XE This command was introduced. 12.0(7)T This command was integrated in Cisco IOS Release 12.0 T for the Cisco 7500 series only. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description show memory scan Displays the number and type of parity errors on your system. memory-size iomem CF-320 Cisco IOS Configuration Fundamentals Command Reference April 2010 memory-size iomem To reallocate the percentage of DRAM to use for I/O memory and processor memory on Cisco 3600 series routers, use the memory-size iomem command in global configuration mode. To revert to the default memory allocation, use the no form of this command. memory-size iomem i/o-memory-percentage no memory-size iomem i/o-memory-percentage Syntax Description Defaults The default memory allocation is 25 percent I/O memory and 75 percent processor memory. Note If the smartinit process has been enabled, the default memory allocation of 25 percent to I/O does not apply. Instead, smartinit examines the network modules and then calculates the I/O memory required. Command Modes Global configuration Command History Usage Guidelines When you specify the percentage of I/O memory in the command line, processor memory automatically acquires the remaining percentage of DRAM memory. Examples The following example allocates 40 percent of the DRAM memory to I/O memory and the remaining 60 percent to processor memory: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# memory-size iomem 40 Router(config)# exit Router# copy system:running-config nvram:startup-config Building configuration... [OK] Router# reload rommon 1 > boot program load complete, entry point: 0x80008000, size: 0x32ea24 i/o-memory-percentage The percentage of DRAM allocated to I/O memory. The values permitted are 10, 15, 20, 25, 30, 40, and 50. A minimum of 4 MB of memory is required for I/O memory.

Use the menu text global configuration command to assign text to items. These commands must use the same menu name and menu selection key. The menu command command has a special keyword for the command argument, menu-exit, that is available only within menus. It is used to exit a submenu and return to the previous menu level, or to exit the menu altogether and return to the EXEC command prompt. You can create submenus that are opened by selecting entries in another menu. Use the menu EXEC command as the command for the submenu item. Note If you nest too many levels of menus, the system prints an error message on the terminal and returns to the previous menu level. When a menu allows connections (their normal use), the command for an entry activating the connection should contain a resume command, or the line should be configured to prevent users from escaping their sessions with the escape-char none command. Otherwise, when they escape from a connection and return to the menu, there will be no way to resume the session and it will sit idle until the user logs out. menu-name Name of the menu. You can specify a maximum of 20 characters. menu-item Number, character, or string used as the key for the item. The key is displayed to the left of the menu item text. You can specify a maximum of 18 menu entries.

As an option, you can also supply the connect string needed to connect initially. When you do not supply this connect string, the command uses the specified connection name. You can also use the resume/next command, which resumes the next connection in the user’s list of connections. This function allows you to create a single menu entry that steps through all of the user’s connections. Note A menu should not contain any exit paths that leave users in an unfamiliar interface environment. When a particular line should always display a menu, that line can be configured with an autocommand line configuration command. Menus can be run on a per-user basis by defining a similar autocommand command for that local username. For more information about the autocommand command, refer to the Cisco IOS Dial Technologies Configuration Guide.

To load the microcode bundled with the GRP system image, use the no form of this command. microcode {oc12-atm | oc12-pos | oc3-pos4} {flash file-id [slot] | system [slot]} no microcode {oc12-atm | oc12-pos | oc3-pos4} [flash file-id [slot] | system [slot]] Syntax Description Defaults The default is to load the image from the GRP card (system). Command Modes Global configuration Command History Usage Guidelines In addition to the Cisco IOS image that resides on the GRP card, each line card on a Cisco 12000 series has a Cisco IOS image. When the router is reloaded, the specified image is loaded onto the GRP card and then automatically downloaded to all the line cards. Normally, you want the same Cisco IOS image on the GRP card and all line cards. However, if you want to upgrade a line card with a new version of microcode for testing or to fix a defect, you might need to load a Cisco IOS image that is different from the one on the line card. Additionally, you might need to load a new image on the line card to work around a problem that is affecting only one of the line cards. oc12-atm | oc12-pos | oc3-pos4 Interface name. flash Loads the image from the Flash file system. file-id Specifies the device and filename of the image file to download from Flash memory.

Then use the microcode command to download the image to the line card, followed by the microcode reload command to start the image. Immediately after you enter the microcode reload command and press Return, the system reloads all microcode. Global configuration mode remains enabled. After the reloading is complete, enter the exit command to return to the EXEC system prompt. To verify that the correct image is running on the line card, use the execute-on slot slot show version command. For additional information on GSR configuration, refer to the documentation specific to your Cisco IOS software release. Examples In the following example, the Cisco IOS software image in slot 0 is downloaded to the line card in slot 10. This software image is used when the system is booted, a line card is inserted or removed, or the microcode reload global configuration command is issued. Router(config)# microcode oc3-POS-4 flash slot0:fip.v141-7 10 Router(config)# microcode reload 10 In this example, the user would issue the execute-on slot 10 show version command to verify that the correct version is loaded.

To load the microcode bundled with the system image, use the no form of this command. microcode interface-type {flash-filesystem:filename [slot] | rom | system [slot]]} no microcode interface-type {flash-filesystem:filename [slot] | rom | system [slot]} Syntax Description Defaults The default is to load from the microcode bundled in the system image. Command Modes Global configuration Command History Usage Guidelines If you do not use the microcode reload command after using the microcode command, the microcode reload command will be written to the configuration file automatically. When using Dual RSPs for simple hardware backup, ensure that the master and slave RSP card contain the same microcode image in the same location when the router is to load the interface processor microcode from a Flash file system. Thus, if the slave RSP becomes the master, it will be able to find the microcode image and download it to the interface processor. interface-type One of the following interface processor names: aip, cip, eip, feip, fip, fsip, hip, mip, sip, sp, ssp, trip, vip, or vip2. flash-filesystem: Flash file system, followed by a colon. Valid file systems are bootflash, slot0, and slot1. Slave devices such as slaveslot0 are invalid. The slave’s file system is not available during microcode reloads. filename Name of the microcode file. slot (Optional) Number of the slot. Range is from 0 to 15. rom If ROM is specified, the router loads from the onboard ROM microcode. system If the system keyword is specified, the router loads the microcode from the microcode bundled into the system image you are running for that interface type.

On releases prior to Release 12.2(17d)SXB, single router mode (SRM) with SSO redundancy does not support stateful switchover for multicast traffic. When a switchover occurs, all multicast hardware switching entries are removed and are then re-created and reinstalled in the hardware by the newly active multilayer switch feature card (MSFC). SRM/SSO is supported in the following releases only: • Release 12.2(17b)SXA and subsequent rebuilds. • Release 12.2(17d)SXB and subsequent rebuilds. Nonstop forwarding (NSF) with SSO redundancy mode supports IPv4. NSF with SSO redundancy mode does not support IPv6, Internetwork Packet Exchange (IPX), and Multiprotocol Label Switching (MPLS). If you have configured MPLS on the Cisco 7600 series routers with redundant supervisor engines, you must configure the Cisco 7600 series router in RPR mode. The switch should not be running in the default mode of SSO. Enter the redundancy command in global configuration mode to enter redundancy configuration mode. You can enter the mode command within redundancy configuration mode. Follow these guidelines when configuring your system for RPR+ mode: • You must install compatible images on the active and standby supervisor engines to support RPR+ mode and SSO mode. • Both supervisor engines must run the same Cisco IOS software version. • Any modules that are not online at the time of a switchover are reset and reloaded on a switchover. • The Forwarding Information Base (FIB) tables are cleared on a switchover. As a result, routed traffic is interrupted until route tables reconverge. The standby supervisor engine reloads on any change of mode and begins to work in the current mode. When you use this command to force the standby supervisor engine to run as a Distributed Forwarding Card (DFC) card, the uplink ports in the standby engine continue to be in use and are not disabled. Release Modification 12.2(14)SX This command was introduced on the Supervisor Engine 720. 12.2(17b)SXA This command was modified.

RPR and SSO need to be configured by the user, however, because a second Cisco IOS process is not available by default on Cisco ASR 1002 and 1004 routers. Enter the redundancy command in global configuration mode to enter redundancy configuration mode. You can enter the mode command within redundancy configuration mode. The Cisco ASR 1006 Router supports a second Route Processor. The second Cisco IOS process can run only on the standby Route Processor. This means that hardware redundancy is available and RPR and SSO do not need to be configured by the user because a second Cisco IOS process is available by default on the Cisco ASR 1006 router. RPR+ mode is not supported on the Cisco ASR 1000 Series Routers. Cisco IOS Release 12.2XNE and 1000 Series Routers Enter the redundancy command in global configuration mode to enter redundancy configuration mode. You can enter the mode command within redundancy configuration mode. RPR mode is not supported on the Cisco 10000 router.

CF-355 Cisco IOS Configuration Fundamentals Command Reference April 2010 monitor event-trace (EXEC) CF-356 Cisco IOS Configuration Fundamentals Command Reference April 2010 monitor event-trace (EXEC) To monitor and control the event trace function for a specified Cisco IOS software subsystem component, use the monitor event-trace command in privileged EXEC mode. monitor event-trace component {clear | continuous | disable | dump [pretty] | enable | one-shot} Cisco 10000 Series Routers monitor event-trace component {disable | dump | enable | size | stacktrace} Catalyst 6500 Series Switches and Cisco 7600 Series Routers monitor event-trace all-traces {continuous [cancel] | dump [merged] [pretty]} monitor event-trace l3 {clear | continuous [cancel] | disable | dump [pretty] | enable | interface type mod/port | one-shot} monitor event-trace spa {clear | continuous [cancel] | disable | dump [pretty] | enable | one-shot} monitor event-trace subsys {clear | continuous [cancel] | disable | dump [pretty] | enable | one-shot} Syntax Description component Name of the Cisco IOS software subsystem component that is the subject of the event trace. To get a list of components that support event tracing, use the monitor event-trace ? command. clear Clears existing trace messages for the specified component from memory on the networking device. continuous Continuously displays the latest event trace entries. disable Turns off event tracing for the specified component. dump Writes the event trace results to the file configured using the monitor event-trace command in global configuration mode. The trace messages are saved in binary format. pretty (Optional) Saves the event trace message in ASCII format. enable Turns on event tracing for the specified component. one-shot Clears any existing trace information from memory, starts event tracing again, and disables the trace when the trace reaches the size specified using the monitor event-trace command in global configuration mode. size Sets the number of messages that can be written to memory for a single instance of a trace. Note Some Cisco IOS software subsystem components set the size by default. To display the size parameter, use the show monitor event-trace component parameters command. When the number of event trace messages in memory exceeds the size, new messages will begin to overwrite the older messages in the file. stacktrace Enables the stack trace at tracepoints. all-traces Displays the configured merged-event traces. monitor event-trace (EXEC) CF-357 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Default The event trace function is disabled by default. Command Modes Privileged EXEC (#) Command History Usage Guidelines Use the monitor event-trace command to control what, when, and how event trace data is collected. Use this command after you have configured the event trace functionality on the networking device using the monitor event-trace command in global configuration mode. Note The amount of data collected from the trace depends on the trace message size configured using the monitor event-trace command in global configuration mode for each instance of a trace. The Cisco IOS software allows for the subsystem components to define whether support for event tracing is enabled or disabled at boot time. You can enable or disable event tracing in two ways: using the monitor event-trace command in privileged EXEC mode or using the monitor event-trace command in global configuration mode. To disable event tracing, you would enter either of these commands with the disable keyword. To enable event tracing again, you would enter either of these commands with the enable keyword. To determine whether you can enable event tracing on a subsystem, use the monitor event-trace ? command to get a list of software components that support event tracing. To determine whether event tracing is enabled by default for the subsystem, use the show monitor event-trace command to display trace messages. merged (Optional) Dumps the entries in all event traces sorted by time. l3 Displays information about the Layer 3 trace. spa Displays information about the Shared Port Adapter (SPA) trace. interface type mod/port Specifies the interface to be logged. cancel (Optional) Cancels the continuous display of latest trace entries. subsys Displays information about the subsystem’s initial trace.

Use the monitor event-trace component dump command to save trace message information for a single event. By default, trace information is saved in binary format. If you want to save trace messages in ASCII format, possibly for additional application processing, use the monitor event-trace component dump pretty command. To write the trace messages for all events currently enabled on a networking device to a file, enter the monitor event-trace dump command. To configure the file where you want to save trace information, use the monitor event-trace command in global configuration mode. The trace messages are saved in a binary format. Examples The following example shows the privileged EXEC commands to stop event tracing, clear the current contents of memory, and reenable the trace function for the interprocess communication (IPC) component. This example assumes that the tracing function is configured and enabled on the networking device. Router# monitor event-trace ipc disable Router# monitor event-trace ipc clear Router# monitor event-trace ipc enable The following example shows how the monitor event-trace one-shot command accomplishes the same function as the previous example except in one command. In this example, once the size of the trace message file has been exceeded, the trace is terminated. Router# monitor event-trace ipc one-shot The following example shows the command for writing trace messages for an event in binary format. In this example, the trace messages for the IPC component are written to a file. Router# monitor event-trace ipc dump The following example shows the command for writing trace messages for an event in ASCII format. In this example, the trace messages for the MBUS component are written to a file. Router# monitor event-trace mbus dump pretty Catalyst 6500 Series Switches and Cisco 7600 Series Routers Examples Only This example shows how to stop event tracing, clear the current contents of memory, and reenable the trace function for the SPA component.

Command Modes Global configuration (config) Command History Usage Guidelines Use the monitor event-trace command to enable or disable event tracing and to configure event trace parameters for Cisco IOS software subsystem components. Note Event tracing is intended for use as a software diagnostic tool and should be configured only under the direction of a Technical Assistance Center (TAC) representative. In Cisco IOS software images that do not provide subsystem support for the event trace function, the monitor event-trace command is not available. The Cisco IOS software allows the subsystem components to define whether support for event tracing is enabled or disabled by default. The command interface for event tracing allows you to change the default two ways: using the monitor event-trace command in privileged EXEC mode or using the monitor event-trace command in global configuration mode. Additionally, default settings do not show up in the configuration file. If the subsystem software enables event tracing by default, the monitor event-trace component enable command will not show up in the configuration file of the networking device; however, disabling event tracing that has been enabled by default by the subsystem will create a command entry in the configuration file. Note The amount of data collected from the trace depends on the trace message size configured using the monitor event-trace command for each instance of a trace. To determine whether you can enable event tracing on a subsystem, use the monitor event-trace ? command to get a list of software components that support event tracing. continuous Continuously displays the latest event trace entries. one-shot Clears any existing trace information from memory, starts event tracing again, and disables the trace when the trace reaches the size specified using the monitor event-trace command.

This command is not supported on Catalyst 6500 series switches that are configured with a Supervisor Engine 2. All ERSPAN source sessions on a switch must use the same source IP address. You enter the origin ip address command to configure the IP address for the ERSPAN source sessions. All ERSPAN destination sessions on a switch must use the same IP address. You enter the ip address command to configure the IP address for the ERSPAN destination sessions. If the ERSPAN destination IP address is not a Supervisor Engine 720 (for example, it is a network sniffer), the traffic arrives with the GRE and RSPAN headers/encapsulation intact. The ERSPAN source session destination IP address, which must be configured on an interface on the destination switch, is the source of traffic that an ERSPAN destination session sends to the destination ports. You configure the same address in both the source and destination sessions with the ip address command. The ERSPAN ID differentiates the ERSPAN traffic arriving at the same destination IP address from different ERSPAN source sessions. The local ERSPAN session limits are as follows: • Total sessions—66 • Source sessions—2 (ingress or egress or both) • Destination sessions—23 The monitor session type command creates a new ERSPAN session or allows you to enter the ERSPAN session configuration mode. ERSPAN uses separate source and destination sessions. You configure the source and destination sessions on different switches. The ERSPAN session configuration mode prompts are as follows: • Router(config-mon-erspan-src)—Indicates the ERSPAN source session configuration mode. • Router(config-mon-erspan-src-dst)—Indicates the ERSPAN source session destination configuration mode. • Router(config-mon-erspan-dst)—Indicates the ERSPAN destination session configuration mode. • Router(config-mon-erspan-dst-src)—Indicates the ERSPAN destination session source configuration mode Table 35 lists the ERSPAN destination session configuration mode syntaxes.

Note In lists, you must enter a space before and after the comma. In ranges, you must enter a space before and after the dash. • interface-range is interface type slot/first-port - last-port . • mixed-interface-list is, in any order, single-interface , interface-range , ... • erspan-flow-id can range from 1 to 1023. When you clear the monitor sessions, follow these syntax guidelines: • The no monitor session session-number command entered with no other parameters clears the session session-number. • session-range is first-session-number-last-session-number. Note When you enter the no monitor session range command, do not enter spaces before or after the dash. If you enter multiple ranges, do not enter spaces before or after the commas. Use the monitor session type local command to configure ingress, egress, or both ingress and egress SPAN sessions.

Table 36 ERSPAN or RSPAN Source Session Configuration Mode Syntaxes Syntax Description monitor session type CF-371 Cisco IOS Configuration Fundamentals Command Reference April 2010 Use the monitor session type local-tx command to configure egress-only SPAN sessions. When you enter the local or the local egress-only SPAN session configuration mode, the prompt changes accordingly to Router(config-mon-local)# or Router(config-mon-local-tx)#, and the following commands are available: • description—Describes the properties for this session using this syntax: description description The description can be up to 240 characters and cannot contain special characters or spaces. • destination—Specifies the destination and the destination properties using this syntax: destination {analysis-module num | anomaly-detector-module num | interface type number | intrusion-detection-module num} • exit—Exits from configuration session mode. • filter vlan vlan-id—Limits the SPAN source traffic to specific VLANs; valid values are from 1 to 4096. • no—Negates a command or sets its defaults. • shutdown—Shuts down this session • source—Specifies the SPAN source interface or VLAN using the following syntax: source {cpu {rp | sp} | {interface type number} | {intrusion-detection-module num} | {vlan vlan-id}} [, | - | rx | tx | both] analysis-module num Specifies the SPAN destination analysis-module. anomaly-detector-module num Specifies the SPAN destination anomaly-detector-module. interface type number Specifies the interface type and number as follows: • GigabitEthernet mod/port • port-channel num—Ethernet Channel of interfaces; valid values are from 1 to 496. ingress (Optional) Configures destinations to receive traffic from attached devices. learning (Optional) Enables MAC address learning from the destinations, which allows the switch to transmit traffic that is addressed to devices attached to the destinations. intrusion-detection-module num Specifies the SPAN destination intrusion-detection-module. cpu rp Associates the local SPAN session number with the CPU on the route processor. cpu sp Associates the local SPAN session number with the CPU on the switch processor. monitor session type CF-372 Cisco IOS Configuration Fundamentals Command Reference April 2010 The local SPAN session limits are as follows: • Total sessions—80 • Source sessions—2 (ingress or egress or both) • Egress only—14 If you enter the filter keyword on a monitored trunk interface, only traffic on the set of specified VLANs is monitored. Only one destination per SPAN session is supported. If you attempt to add another destination interface to a session that already has a destination interface configured, you get an error. You must first remove a SPAN destination interface before changing the SPAN destination to a different interface. You can configure up to 64 SPAN destination interfaces, but you can have one egress SPAN source interface and up to 128 ingress source interfaces only. A SPAN session can either monitor VLANs or monitor individual interfaces, but it cannot monitor both specific interfaces and specific VLANs. Configuring a SPAN session with a source interface and then trying to add a source VLAN to the same SPAN session causes an error. Configuring a SPAN session with a source VLAN and then trying to add a source interface to that session also causes an error. You must first clear any sources for a SPAN session before switching to another type of source. Port channel interfaces display in the list of interface options if you have them configured. VLAN interfaces are not supported. However, you can span a particular VLAN by entering the monitor session session source vlan vlan-id command. When you configure the destination, use these guidelines: • A single-interface is as follows: – interface type slot/port; type is fastethernet, gigabitethernet, or tengigabitethernet. – interface port-channel number Note Destination port channel interfaces must be configured with the channel-group group-num mode on command and the no channel-protocol command. • An interface-list is single-interface , single-interface , single-interface ... interface type number Specifies the interface type and number as follows: • FastEthernet mod/port • GigabitEthernet mod/port • Port-channel num—Ethernet Channel of interfaces; valid values are from 1 to 496. vlan vlan-id Specifies the VLAN; valid values are from 1 to 4094. , (Optional) Specifies another range of interfaces. - (Optional) Specifies a range of interfaces. both (Optional) Monitors the received and the transmitted traffic. rx (Optional) Monitors the received traffic only. tx1 (Optional) Monitors the transmitted traffic only. 1. When you enter the local-tx keyword, the rx and both keywords are not available and the tx keyword is required. monitor session type CF-373 Cisco IOS Configuration Fundamentals Command Reference April 2010 Note In lists, you must enter a space before and after the comma. In ranges, you must enter a space before and after the dash. • An interface-range is interface type slot/first-port - last-port. • A mixed-interface-list is, in any order, single-interface , interface-range , ... • A single-vlan is the ID number of a single VLAN. • A single-list is single-vlan , single-vlan , single-vlan ... • A vlan-range is first-vlan-ID - last-vlan-ID. • A mixed-vlan-list is, in any order, single-vlan , vlan-range , ... When you clear the monitor sessions, follow these syntax guidelines: • The no monitor session session-number command entered with no other parameters clears the session session-number. • session-range is first-session-number-last-session-number. Note When you enter the no monitor session range command, do not enter spaces before or after the dash. If you enter multiple ranges, do not enter spaces before or after the commas.

To set the identity to the default value, use the no form of this command. mop device-code {cisco | ds200} no mop device-code {cisco | ds200} Syntax Description Defaults Cisco device code Command Modes Global configuration Command History Usage Guidelines The sysid messages and request program messages use the identity information indicated by this command. Examples The following example identifies a DECserver 200 device as sending MOP sysid and request program messages: mop device-code ds200 Related Commands cisco Denotes a Cisco device code. This is the default. ds200 Denotes a DECserver 200 device code. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description mop sysid Enables an interface to send out periodic MOP system identification messages. mop retransmit-timer CF-376 Cisco IOS Configuration Fundamentals Command Reference April 2010 mop retransmit-timer To configure the length of time that the Cisco IOS software waits before resending boot requests to a Maintenance Operation Protocol (MOP) server, use the mop retransmit-timer command in global configuration mode. To reinstate the default value, use the no form of this command. mop retransmit-timer seconds no mop retransmit-timer Syntax Description Defaults 4 seconds Command Modes Global configuration Command History Usage Guidelines By default, when the software sends a request that requires a response from a MOP boot server and the server does not respond, the message is re-sent after 4 seconds. If the MOP boot server and router are separated by a slow serial link, it might take longer than 4 seconds for the software to receive a response to its message. Therefore, you might want to configure the software to wait longer than 4 seconds before resending the message if you are using such a link. Examples In the following example, if the MOP boot server does not respond within 10 seconds after the router sends a message, the server will resend the message: mop retransmit-timer 10 Related Commands seconds Sets the length of time (in seconds) that the software waits before resending a message. The value is a number from 1 to 20. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

Optional formats include ascii, binary, and ebcdic. Command Modes EXEC Command History Usage Guidelines The more system:running-config command displays the same output as the show running-config command. The more nvram:startup-config command is recommended as a replacement for the show startup-config command and the show configuration command. You can use this command to display configuration files, as follows: • The more nvram:startup-config command displays the startup configuration file contained in NVRAM or specified by the CONFIG_FILE environment variable. The Cisco IOS software informs you whether the displayed configuration is a complete configuration or a distilled version. A distilled configuration is one that does not contain access lists. • The more system:running-config command displays the running configuration. These commands show the version number of the software used when you last changed the configuration file. You can also display the contents of files on remote systems using the more command. For example, you could display a saved running configuration file on an FTP server using more ftp://username:password@ftp-host1/mydirectory/7200-basic-running-config. See the description of the copy command for more information on file-system prefixes available in the Cisco IOS CLI. Options for filtering and redirecting the output of this command are available by appending a pipe character (|).

Defaults Enabled on all lines. Command Modes Line configuration Command History Usage Guidelines This command determines whether the router will display the MOTD banner when an EXEC session is created on the specified line or lines. The MOTD banner is defined with the banner motd global configuration command. By default, the MOTD banner is enabled on all lines. Disable the MOTD banner on specific lines using the no motd-banner line configuration command. The MOTD banners can also be disabled by the no exec-banner line configuration command, which disables both MOTD banners and EXEC banners on a line. If the no exec-banner command is configured on a line, the MOTD banner will be disabled regardless of whether the motd-banner command is enabled or disabled. Table 37 summarizes the effects of the exec-banner command and the motd-banner command. For reverse Telnet connections, the EXEC banner is never displayed. Instead, the incoming banner is displayed. The MOTD banner is displayed by default, but it is disabled if either the no exec-banner command or no motd-banner command is configured.

Command Description terminal padding Changes the character padding on a specific output character for the current session. parity CF-397 Cisco IOS Configuration Fundamentals Command Reference April 2010 parity To define generation of a parity bit, use the parity command in line configuration mode. To specify no parity, use the no form of this command. parity {none | even | odd | space | mark} no parity Syntax Description Defaults No parity. Command Modes Line configuration Command History Usage Guidelines Communication protocols provided by devices such as terminals and modems sometimes require a specific parity bit setting. Refer to the documentation for your device to determine required parity settings. If you use this command to set parity on Cisco AS5350 and Cisco AS5400 NextPort lines, do not also set parity by means of S-register settings in a modemcap. (A modemcap is a series of parameter settings that are sent to your modem to configure it to interact with a Cisco device in a specified way. Cisco IOS software defines modemcaps that have been found to properly initialize most modems so that they function properly with Cisco routers and access servers.) Examples In the following example, even parity is configured for line 34: Router(config)# line 34 Router(config-line)# parity even none No parity. This is the default. even Even parity. odd Odd parity. space Space parity. mark Mark parity. Release Modification 10.0 This command was introduced. 12.4 This command was modified to enable parity setting on Cisco AS5350 and Cisco AS5400 NextPort lines. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. parity CF-398 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description terminal parity Defines the generation of the parity bit for the current for the current session and line. parser cache CF-399 Cisco IOS Configuration Fundamentals Command Reference April 2010 parser cache To reenable the Cisco IOS software parser cache after disabling it, use the parser cache command in global configuration mode. To disable the parser cache, use the no form of this command. parser cache no parser cache Syntax Description This command has no arguments or keywords. Defaults Parser cache is enabled by default. Command Modes Global configuration Command History Usage Guidelines The Parser Cache feature optimizes the parsing (translation and execution) of Cisco IOS software configuration command lines by remembering how to parse recently encountered command lines, decreasing the time required to process large configuration files. The parser cache is enabled by default. However, if you wish to disable the parser cache, you may do so using the no parser cache command in global configuration mode. To reenable the parser cache after it has been disabled, use the parser cache command. When the no parser cache is issued, the command line appears in the running configuration file. However, if the parser cache is reenabled, no command line appears in the running configuration file. Examples In the following example, the Cisco IOS software Parser Cache feature is disabled: Router(config)# no parser cache Related Commands Release Modification 12.1(5)T This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description clear parser cache Clears the parse cache entries and hit/miss statistics stored for the Parser Cache feature. show parser statistics Displays statistics about the last configuration file parsed and the status of the Parser Cache feature. parser command serializer CF-400 Cisco IOS Configuration Fundamentals Command Reference April 2010 parser command serializer To enable configuration access only to the users holding a configuration lock and to prevent other clients from accessing the running configuration, use the parser command serializer command in global configuration mode. To disable this configuration, use the no form of this command. parser command serializer no parser command serializer Syntax Description This command has no arguments or keywords. Command Default Access is granted only to the user holding the lock. Command Modes Global configuration (config) Command History Usage Guidelines The Parser Concurrency and Locking Improvements feature ensures that exclusive access is granted only to a requested process and prevents other users from concurrently accessing the Cisco IOS configuration. That is, it prevents simultaneous execution of two or more commands. Use the parser command serializer command to configure the Parser Concurrency and Locking Improvements feature. Examples The following example shows how to configure the Parser Concurrency and Locking Improvements feature: Router# configure terminal Router(config)# parser command serializer Related Commands Release Modification 12.2(33)SRE This command was introduced. Command Description configuration mode exclusive Enables single-user (exclusive) access functionality for the Cisco IOS CLI. configure terminal lock Locks the running configuration into exclusive configuration mode for the duration of your configuration session. test parser session-lock Tests the behavior of the Parser Concurrency and Locking Improvements feature. parser config cache interface CF-401 Cisco IOS Configuration Fundamentals Command Reference April 2010 parser config cache interface To reduce the time required for the command-line interpreter to execute commands that manage the running system configuration files, use the parser config cache interface command in global configuration mode. To disable the reduced command execution time functionality, use the no form of this command. parser config cache interface no parser config cache interface Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration (config) Command History Usage Guidelines Enable the parser config cache interface command to reduce the execution time required for running configuration management commands such as the show running-configuration, write terminal, and copy system:running-configuration commands. Information for these configuration management commands is supplied by nonvolatile generation (NVGEN) processes that query the system for configuration details. The parser config cache interface command is especially useful for managing large system configurations that contain numerous interface configurations. Once enabled, the command provides faster execution of the NVGEN commands that process the running system configuration by caching interface configurations in system memory, and by retrieving only configuration information that has changed. For this reason, the device on which this command is enabled must have enough memory available to store the interface configuration. For example, if the interface configurations take up 15 KB of memory, using this command would require having an additional 15 KB of memory space available. The first time you display the configuration file, you will not see much evidence of improvement in performance because the interface cache will be filled up. However, you will notice performance improvements when you enter subsequent NVGEN-type commands such as the show running-configuration EXEC command. Release Modification 12.3(7)T This command was introduced. 12.2(25)S This command was integrated into Cisco IOS Release 12.2(25)S. 12.2(27)SBC This command was integrated into Cisco IOS Release 12.2(27)SBC. 12.2(33)SRC This command was integrated into Cisco IOS Release 12.2(33)SRC. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB and implemented on the Cisco 10000 series. 12.2(33)SXI This command was integrated into Cisco IOS Release 12.2(33)SXI. parser config cache interface CF-402 Cisco IOS Configuration Fundamentals Command Reference April 2010 Each time the interface configuration is changed, the interface cache is flushed. Entering an NVGEN-type command after modifying the interface configuration will once again not show any performance improvement until the next NVGEN-type command is entered. Examples The following example shows how to enable the functionality for reducing the time required for the command-line interpreter to execute commands that manage the running system configuration files: Router(config)# parser config cache interface Related Commands Command Description copy system:running-configuration Copies the running configuration to another destination. show running-configuration Displays the configuration currently running on the terminal. write terminal Displays the configuration currently running on the terminal. parser config partition CF-403 Cisco IOS Configuration Fundamentals Command Reference April 2010 parser config partition To enable configuration partitioning, use the parser config partition command. To disable the partitioning of the running configuration, use the no form of this command. parser config partition no parser config partition Syntax Description No arguments or keywords. Command Default This command is enabled by default. Command Modes Global configuration (config) Command History Usage Guidelines This command controls (enables or disables) the Configuration Partitioning feature. Note This command is not related to disk partitions or disk partitioning. To display the list of commands that make up the current running configuration for a specific part (“partition”) of the system’s global running configuration, use the show running-config partition command in privileged Exec mode. The Configuration Partitioning feature uses a small amount of system resources. The no parser config partition command allows you to disable this feature if the feature is not needed on your system. Note Only the no form of this command will appear in configuration files. To determine if config partitioning is supported on your system and whether it is enabled, use the show running-config parser ? command. Examples The following example shows how to disable partitioning of the system running configuration: Router> enable Router# config t Enter configuration commands, one per line. End with CNTL/Z. Release Modification 12.2(33)SRB This command was introduced as part of the Configuration Partitioning feature. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB and implemented on the Cisco 10000 series. 12.2(33)SXI This command was integrated into Cisco IOS Release 12.2(33)SXI. parser config partition CF-404 Cisco IOS Configuration Fundamentals Command Reference April 2010 Router(config)# no parser config partition System configured Related Commands Command Description show running-config partition Displays the list of commands that make up the current running configuration for a specific part of the system’s global running configuration.

The number of partition size entries must be equal to the number of specified partitions. partitions Number of partitions in Flash memory. Can be 1 or 2. size1 (Optional) Size of the first partition (in megabytes). size2 (Optional) Size of the second partition (in megabytes). Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. partition CF-406 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines For the Cisco 1600 series and Cisco 3600 series routers, to undo partitioning, use the partition flash-filesystem:1 or no partition flash-filesystem: command. For other Class B platforms, use either the partition flash 1 or no partition flash command. If there are files in a partition other than the first, you must use the erase flash-filesystem:partition-number command to erase the partition before reverting to a single partition. When creating two partitions, you must not truncate a file or cause a file to spill over into the second partition. Examples The following example creates two partitions of 4 MB each in Flash memory: Router(config)# partition flash 2 4 4 The following example divides the Flash memory card in slot 0 into two partitions, each 8 MB in size on a Cisco 3600 series router: Router(config)# partition slot0: 2 8 8 The following example creates four partitions of equal size in the card on a Cisco 1600 series router: Router(config)# partition flash: 4 path (archive configuration) CF-407 Cisco IOS Configuration Fundamentals Command Reference April 2010 path (archive configuration) To specify the location and filename prefix for the files in the Cisco IOS configuration archive, use the path command in archive configuration mode. To disable this function, use the no form of this command. path url no path url Syntax Description Command Default If this command is not configured, no location or filename prefix is specified for files in the Cisco IOS configuration archive. Command Modes Archive configuration (config-archive) Command History Usage Guidelines When this command is entered, an archive file of the running configuration is saved when the archive config, write-memory, or copy running-config startup-config command is entered. URLs are commonly used to specify files or location on the World Wide Web. On Cisco routers, URLs can be used to specify the location of a file or directory on a router or a remote file server. The path command uses a URL to specify the location and filename prefix for the Cisco IOS configuration archive. The locations or file systems that you can specify in the url argument are as follows: • If your platform has disk0—disk0:, disk1:, ftp:, pram:, rcp:, slavedisk0:, slavedisk1:, or tftp: • If your platform does not have disk0—ftp:, http:, pram:, rcp:, or tftp: The colon is required in the location format. The filename of the first archive file is the filename specified in the url argument followed by -1. The filename of the second archive file is the filename specified in the url argument followed by -2 and so on. url URL (accessible by the Cisco IOS file system) used for saving archive files of the running configuration file in the Cisco IOS configuration archive.

To include the router hostname in the archive file filename, enter the characters $h (for example, disk0:$h). To include the date and time in the archive file filename, enter the characters $t. When a configuration archive operation is attempted on a local file system, the file system is tested to determine if it is writable and if it has sufficient space to save an archive file. If the file system is read-only or if there is not enough space to save an archive file, an error message is displayed. If you specify the tftp: file server as the location with the path command, you need to create the configuration file on the TFTP file server and change the file’s privileges before the archive config command works properly. Examples The following example of the path command shows how to specify the hostname, date, and time as the filename prefix for which to save archive files of the running configuration. In this example, the time-period command is also configured to automatically save an archive file of the running configuration every 20 minutes. configure terminal ! archive path disk0:$h$t time-period 20 end The following is sample output from the show archive command illustrating the format of the resulting configuration archive filenames. Router# show archive There are currently 3 archive configurations saved. The next archive file will be named routerJan-16-01:12:23.019-4 Archive # Name 0 1 disk0:routerJan-16-00:12:23.019-1 2 disk0:routerJan-16-00:32:23.019-2 3 disk0:routerJan-16-00:52:23.019-3 <- Most Recent 4 5 6 7 8 9 10 11 12 13 14 Cisco IOS Configuration Archive on the TFTP File Server The following example shows how to use the path command to specify the TFTP file server, address 10.48.71.226, as the archive configuration location and router-cfg as the configuration filename. First you create the configuration file on the TFTP server and change the file’s privileges, then you can save the configuration file to the configuration archive. The following example shows the commands to use to create the file and change the file’s privileges on the TFTP server (UNIX commands): > touch router-cfg-1 path (archive configuration) CF-409 Cisco IOS Configuration Fundamentals Command Reference April 2010 > chmod 777 router-cfg-1 The following example show how to create the configuration archive, save the running configuration to the archive, and display the files in the archive: configure terminal ! archive path tftp://10.48.71.226/router-cfg exit exit ! archive config Router# show archive The next archive file will be named tftp://10.48.71.226/router-cfg-2 Archive # Name 0 1 tftp://10.48.71.226/router-cfg-1 <- Most Recent 2 3 4 5 6 7 8 9 10 11 12 13 14 The following is sample output from the show archive command if you did not create the configuration file on the TFTP server before attempting to archive the current running configuration file: configure terminal ! archive path tftp://10.48.71.226/router-cfg exit exit archive config Router# show archive The next archive file will be named tftp://10.48.71.226/router-cfg-1 Archive # Name 0 1 2 3 4 5 6 7 8 9 10 11 12 path (archive configuration) CF-410 Cisco IOS Configuration Fundamentals Command Reference April 2010 13 14 Related Commands Command Description archive Enters archive configuration mode. archive config Saves a copy of the current running configuration to the Cisco IOS configuration archive. configure confirm Confirms replacement of the current running configuration with a saved Cisco IOS configuration file. configure replace Replaces the current running configuration with a saved Cisco IOS configuration file. maximum Sets the maximum number of archive files of the running configuration to be saved in the Cisco IOS configuration archive. show archive Displays information about the files saved in the Cisco IOS configuration archive. time-period Sets the time increment for automatically saving an archive file of the current running configuration in the Cisco IOS configuration archive. periodic CF-411 Cisco IOS Configuration Fundamentals Command Reference April 2010 periodic To specify a recurring (weekly) time range for functions that support the time-range feature, use the periodic command in time-range configuration mode. To remove the time limitation, use the no form of this command. periodic days-of-the-week hh:mm to [days-of-the-week] hh:mm no periodic days-of-the-week hh:mm to [days-of-the-week] hh:mm Syntax Description Defaults No recurring time range is defined. Command Modes Time-range configuration (config-time-range) Command History Usage Guidelines For Cisco IOS Release 12.2(11)T, IP and Internetwork Packet Exchange (IPX) extended access lists are the only functions that can use time ranges. For further information on using these functions, refer to the Cisco IOS IP Configuration Guide and the Cisco IOS AppleTalk and Novell IPX Configuration Guide. days-of-the-week The first occurrence of this argument is the starting day or day of the week that the associated time range is in effect. The second occurrence is the ending day or day of the week the associated statement is in effect. This argument can be any single day or combinations of days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. Other possible values are: • daily—Monday through Sunday • weekdays—Monday through Friday • weekend—Saturday and Sunday If the ending days of the week are the same as the starting days of the week, they can be omitted. hh:mm The first occurrence of this argument is the starting hours:minutes that the associated time range is in effect. The second occurrence is the ending hours:minutes the associated statement is in effect. The hours:minutes are expressed in a 24-hour clock. For example, 8:00 is 8:00 a.m. and 20:00 is 8:00 p.m. to Entry of the to keyword is required to complete the range “from start-time to end-time.” Release Modification 12.0(1)T This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. periodic CF-412 Cisco IOS Configuration Fundamentals Command Reference April 2010 The periodic command is one way to specify when a time range is in effect. Another way is to specify an absolute time period with the absolute command. Use either of these commands after the time-range global configuration command, which specifies the name of the time range. Multiple periodic entries are allowed per time-range command. If the end days-of-the-week value is the same as the start value, they can be omitted. If a time-range command has both absolute and periodic values specified, then the periodic items are evaluated only after the absolute start time is reached, and are not further evaluated after the absolute end time is reached. Note All time specifications are taken as local time. To ensure that the time range entries take effect at the desired times, you should synchronize the system software clock using Network Time Protocol (NTP).

Command Modes User EXEC (>) Privileged EXEC (#) Command History protocol (Optional) Protocol keyword, either appletalk, atm, clns, decnet, ipx, or srb. If a protocol is not specified, a basic ping will be sent using IP (IPv4). For extended options for ping over IP, see the documentation for the ping ip command. The ping atm interface atm, ping ip, ping ipv6, ping sna, and ping vrf commands are documented separately. tag (Optional) Specifies a tag encapsulated IP (tagIP) ping. host-name Hostname of the system to ping. If a host-name or system-address is not specified at the command line, it will be required in the ping system dialog. system-address Address of the system to ping. If a host-name or system-address is not specified at the command line, it will be required in the ping system dialog. Release Modification 10.0 This command was introduced. 12.0(7)T The ping sna command was introduced. 12.1(12c)E The ping vrf command was introduced. 12.2(2)T Support for the IPv6 protocol was added. 12.2(13)T The atm protocol keyword was added. The following keywords were removed because the Apollo Domain, Banyan VINES, and XNS protocols are no longer supported in Cisco IOS software: • apollo • vines • xns 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. 12.2(25)SG This command was integrated into Cisco IOS Release 12.2(25)SG. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. ping CF-415 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines The ping command sends an echo request packet to an address then waits for a reply. Ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached or is functioning. For example, the ping clns command sends International Organization for Standardization (ISO) CLNS echo packets to test the reachability of a remote router over a connectionless Open System Interconnection (OSI) network. If you enter the ping command without any keywords or argument values, an interactive system dialog prompts you for the additional syntax appropriate to the protocol you specify. (See the “Examples” section.) To exit the interactive ping dialog before responding to all the prompts, type the escape sequence. The default escape sequence is Ctrl-^, X (Simultaneously press and release the Ctrl, Shift, and 6 keys and then press the X key). The escape sequence will vary depending on your line configuration. For example, another commonly used escape sequence is Ctrl-c. Table 40 describes the test characters sent by the ping facility. Note Not all protocols require hosts to support pings. For some protocols, the pings are Cisco defined and can be answered only by another Cisco router. The availability of protocol keywords depends on what protocols are enabled on your system. Issuing the ping command in user EXEC mode will generally offer fewer syntax options than issuing the ping command in privileged EXEC mode. Examples After you enter the ping command in privileged EXEC mode, the system prompts you for a protocol keyword. The default protocol is IP. If you enter a hostname or address on the same line as the ping command, the default action is taken as appropriate for the protocol type of that name or address. The following example is sample dialog from the ping command using default values. The specific dialog varies somewhat from protocol to protocol. Router# ping Protocol [ip]: Table 40 ping Test Characters Character Description ! Each exclamation point indicates receipt of a reply. . Each period indicates that the network server timed out while waiting for a reply. U A destination unreachable error protocol data unit (PDU) was received. C A congestion experienced packet was received. I User interrupted test.

Command Modes Privileged EXEC Command History Usage Guidelines The ping (packet internet groper) command tests the reachability of a remote router over a connectionless Open System Interconnection (OSI) network. The command sends ISO CLNS echo packets to an address and waits for a reply. Ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached or is functioning. When you type the ping command, you are prompted to enter options before the ping command executes. The characters in brackets ([]) indicate default values. When you want to use a default value, press Enter on your keyboard. If you enter a hostname or system address when you enter the ping command, the default action is taken for the protocol type of that hostname or system address. The optional data, df-bit, repeat, size, source, timeout, and validate keywords can be used to prevent extended ping command output. You can use as many of these keywords as you need, and you can use them in any order after the hostname or system-address arguments. When you enter the ethernet protocol option, you will be prompted to enter MAC address and maintenance domain in addition to the information common across protocols. To terminate a ping session before it completes, type the escape sequence (Ctrl-^ X) by simultaneously pressing and releasing the Ctrl, Shift, and 6 keys and then pressing the X key. Note Not all protocols require hosts to support pings. For some protocols, the pings are defined by Cisco and answered only by a Cisco router. Table 43 describes the test characters that the ping operation uses. ng seconds (Optional) Integer in the range of 0 to 3600. The default is 2. validate (Optional) Validates the reply data. Release Modification 10.0 This command was introduced. 12.0 The following keywords were added in Cisco IOS Release 12.0: data, df-bit, repeat, size, source, timeout, validate. 12.2(33)SRA The ethernet option for protocol was added in Cisco IOS Release 12.2(33)SRA.

The default is 2 seconds. Range is from 0 to 3600. ping ip CF-422 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Modes Privileged Exec Command History Usage Guidelines The ping command sends an echo request packet to an address, then awaits a reply. Ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached or is functioning. To abnormally terminate a ping session, type the escape sequence—by default, Ctrl-^ X. You type the default by simultaneously pressing and releasing the Ctrl, Shift, and 6 keys, and then pressing the X key. Table 44 describes the test characters that the ping facility sends. Note Not all protocols require hosts to support pings. For some protocols, the pings are Cisco-defined and are only answered by another Cisco router. Examples After you enter the ping command in privileged mode, the system prompts you for a protocol keyword. The default protocol is IP. If you enter a host name or address on the same line as the ping command, the default action is taken as appropriate for the protocol type of that name or address. validate (Optional) Validates the reply data. verbose (Optional) Enables verbose output, which lists individual ICMP packets, as well as Echo Responses. Release Modification 10.0 This command was introduced. 12.0 The data, df-bit, repeat, size, source, timeout, and validate keywords were added. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.

Table 45 ping Field Descriptions Field Description Protocol [ip]: Prompts for a supported protocol. The default is IP. Target IP address: Prompts for the IP address or host name of the destination node you plan to ping. If you have specified a supported protocol other than IP, enter an appropriate address for that protocol here. The default is none. Repeat count [5]: Prompts for the number of ping packets that will be sent to the destination address. The default is 5 packets. Datagram size [100]: Prompts for the size of the ping packet (in bytes). The default is 100 bytes. Timeout in seconds [2]: Prompts for the timeout interval. The default is 2 seconds. Extended commands [n]: Specifies whether a series of additional commands appears. Sweep range of sizes [n]: Allows you to vary the sizes of the echo packets being sent. This capability is useful for determining the minimum sizes of the MTUs configured on the nodes along the path to the destination address. Packet fragmentation contributing to performance problems can then be reduced. !!!!! Each exclamation point (!) indicates receipt of a reply. A period (.) indicates that the network server timed out while waiting for a reply. Other characters may appear in the ping output display, depending on the protocol type. Success rate is 100 percent Indicates the percentage of packets successfully echoed back to the router. Anything less than 80 percent is usually considered problematic. round-trip min/avg/max = 1/2/4 ms Indicates the round-trip travel time intervals for the protocol echo packets, including minimum/average/maximum (in milliseconds). ping ip CF-424 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description ping ipv6 Tests the connection to a remote host on the network using IPv6. ping vrf Tests the connection in the context of a specific VPN (VRF). ping vrf CF-425 Cisco IOS Configuration Fundamentals Command Reference April 2010 ping vrf To test a connection in the context of a specific VPN connection, use the ping vrf command in user EXEC or privileged EXEC mode. ping vrf vrf-name [tag] [connection] target-address [connection-options] Syntax Description Command Default The default connection type for ping is IPv4. Command Modes User EXEC Privileged EXEC Command History Usage Guidelines A VPN routing/forwarding (VRF) instance is used to identify a VPN. To check if a configured VRF is working, you can use the ping vrf command. When attempting to ping from a provider edge (PE) router to a customer edge (CE) router, or from a PE router to PE router, the standard ping command will not usually work. The ping vrf command allows you to ping the IP addresses of LAN interfaces on CE routers. If you are on a PE router, be sure to indicate the specific VRF (VPN) name, as shown in the “Examples” section. If all required information is not provided at the command line, the system will enter the interactive dialog (extended mode) for ping. vrf-name The name of the VPN (VRF context). tag (Optional) Specifies a tag encapsulated IP (tagIP) ping. connection (Optional) Connection options include atm, clns, decnet, ip, ipv6, ipx, sna, or srb. The default is ip. target-address The destination ID for the ping operation. Usually, this is the IPv4 address of the host. For example, the target for an IPv4 ping in a VRF context would be the IPv4 address or domain name of the target host. The target for an IPv6 ping in a VRF context would be the IPv6 prefix or domain name of the target host. • If the target address is not specified, the CLI will enter the interactive dialog for ping. connection-options (Optional) Each connection type may have its own set of connection options. For example, connection options for IPv4 include source, df-bit, and timeout. See the appropriate ping command documentation for details. Release Modification 12.1(12c)E, 12.2 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. ping vrf CF-426 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples In the following example, the target host in the domain 209.165.201.1 is pinged (using IP/ICMP) in the context of the “Customer_A” VPN connection.

Command Description show power Displays information about the power status. printer CF-431 Cisco IOS Configuration Fundamentals Command Reference April 2010 printer To configure a printer and assign a server tty line (or lines) to it, use the printer command in global configuration mode. To disable printing on a tty line, use the no form of this command. printer printer-name {line number | rotary number} [newline-convert | formfeed] no printer Syntax Description Defaults No printers are defined by default. Command Modes Global configuration Command History Usage Guidelines This command enables you to configure a printer for operations and assign either a single tty line or a group of tty lines to it. To make multiple printers available through the same printer name, specify the number of a rotary group. In addition to configuring the printer with the printer command, you must modify the file /etc/printcap on your UNIX system to include the definition of the remote printer in the Cisco IOS software. Refer to the Cisco IOS Configuration Fundamentals Configuration Guide for additional information. Use the optional newline-convert keyword in UNIX environments that cannot handle single-character line terminators. This converts newline characters to a carriage-return, linefeed sequence. Use the formfeed keyword when using the line printer daemon (lpd) protocol to print and your system is unable to separate individual output jobs with a form feed (page eject). You can enter the newline-convert and formfeed keywords together and in any order. Examples In the following example a printer named printer1 is configured and output is assigned to tty line 4: Router(config)# printer printer1 line 4 printer-name Printer name. line number Assigns a tty line to the printer. rotary number Assigns a rotary group of tty lines to the printer. newline-convert (Optional) Converts newline (linefeed) characters to a two-character sequence “carriage-return, linefeed” (CR+LF). formfeed (Optional) Causes the Cisco IOS software to send a form-feed character (ASCII 0x0C) to the printer tty line immediately following each print job received from the network. Release Modification 10.3 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. printer CF-432 Cisco IOS Configuration Fundamentals Command Reference April 2010 Related Commands Command Description clear line Returns a terminal line to idle state. private CF-433 Cisco IOS Configuration Fundamentals Command Reference April 2010 private To save user EXEC command changes between terminal sessions, use the private command in line configuration mode. To restore the default condition, use the no form of this command. private no private Syntax Description This command has no arguments or keywords. Defaults User-set configuration options are cleared with the exit EXEC command or when the interval set with the exec-timeout line configuration command has passed. Command Modes Line configuration Command History Usage Guidelines This command ensures that the terminal parameters set by the user remain in effect between terminal sessions. This behavior is desirable for terminals in private offices. Examples In the following example, line 15 (in this example, vty 1) is configured to keep all user-supplied settings at system restarts: Router(config)# line 15 Router(config-line)# private Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description exec-timeout Sets the interval that the EXEC command interpreter waits until user input is detected. exit Exits any configuration mode, or closes an active terminal session and terminates the EXEC. privilege CF-434 Cisco IOS Configuration Fundamentals Command Reference April 2010 privilege To configure a new privilege level for users and associate commands with that privilege level, use the privilege command in global configuration mode. To reset the privilege level of the specified command or commands to the default and remove the privilege level configuration from the running configuration file, use the no form of this command. Note As of Cisco IOS Releases 12.3(6) and 12.3(6)T, the no form of the privilege command and the reset keyword perform the same functions. privilege mode [all] {level level | reset} command-string no privilege mode [all] {level level | reset} command-string Syntax Description Defaults User EXEC mode commands are privilege level 1. Privileged EXEC mode and configuration mode commands are privilege level 15. Command Modes Global configuration mode Configuration mode for the specified command. See Table 46 in the “Usage Guidelines” section for a list of options for this argument. all (Optional) Changes the privilege level for all the suboptions to the same level. level level Specifies the privilege level you are configuring for the specified command or commands. The level argument must be a number from 0 to 15. reset Resets the privilege level of the specified command or commands to the default and removes the privilege level configuration from the running configuration file. Note For Cisco IOS software releases earlier than Release 12.3(6) and Release 12.3(6)T, you use the no form of this command to reset the privilege level to the default. The default form of this command will still appear in the configuration file. To completely remove a privilege configuration, use the reset keyword. command-string Command associated with the specified privilege level. If the all keyword is used, specifies the command and subcommands associated with the privilege level. privilege CF-435 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command History Usage Guidelines The password for a privilege level defined using the privilege global configuration command is configured using the enable secret command. Level 0 can be used to specify a more-limited subset of commands for specific users or lines. For example, you can allow user “guest” to use only the show users and exit commands. Note There are five commands associated with privilege level 0: disable, enable, exit, help, and logout. If you configure AAA authorization for a privilege level greater than 0, these five commands will not be included. When you set the privilege level for a command with multiple words, note that the commands starting with the first word will also have the specified access level. For example, if you set the show ip route command to level 15, the show commands and show ip commands are automatically set to privilege level 15—unless you set them individually to different levels. This is necessary because you can’t execute, for example, the show ip command unless you have access to show commands. To change the privilege level of a group of commands, use the all keyword. When you set a group of commands to a privilege level using the all keyword, all commands which match the beginning string are enabled for that level, and all commands which are available in submodes of that command are enabled for that level. For example, if you set the show ip keywords to level 5, show and ip will be changed to level 5 and all the options that follow the show ip string (such as show ip accounting, show ip aliases, show ip bgp, and so on) will be available at privilege level 5. Table 46 shows some of the keyword options for the mode argument in the privilege command. The available mode keywords will vary depending on your hardware and software version. To see a list of available mode options on your system, use the privilege ? command. . Release Modification 10.3 This command was introduced. 12.0(22)S, 12.2(13)T The all keyword was added. 12.3(6), 12.3(6)T The no form of the command performs the same function as the reset keyword. 12.2(33)SRA This command was integrated into Cisco IOS release 12.(33)SRA. 12.2SX This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware. 12.2(33)SRE This command was integrated into Cisco IOS release 12.(33)SRE.

To reset this value to the system default, use the no form of this command. process-max-time milliseconds no process-max-time milliseconds Syntax Description Defaults The default maximum process time is 200 milliseconds. Command Modes Global configuration Command History Usage Guidelines Lowering the maximum time a process can run is useful in some circumstances to ensure equitable division of CPU time among different tasks. Only use this command if recommended to do so by the Cisco Technical Assistance Center (TAC). Examples The following example limits the duration that a process will run to 100 milliseconds: Router(config)# process-max-time 100 milliseconds Maximum duration (in milliseconds) that a process can run before suspension. The range is from 20to 200 milliseconds. Release Modification 12.1 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. prompt CF-443 Cisco IOS Configuration Fundamentals Command Reference April 2010 prompt To customize the CLI prompt, use the prompt command in global configuration mode. To revert to the default prompt, use the no form of this command. prompt string no prompt [string] Syntax Description Defaults The default prompt is either Router or the name defined with the hostname global configuration command, followed by an angle bracket (>) for user EXEC mode or a pound sign (#) for privileged EXEC mode. Command Modes Global configuration Command History Usage Guidelines You can include customized variables when specifying the prompt. All prompt variables are preceded by a percent sign (%).

Command Modes User EXEC Priviledged EXEC Command History Usage Guidelines Use the pwd command to show which directory or file system is specified as the default by the cd command. For all EXEC commands that have an optional filesystem argument, the system uses the file system specified by the cd command when you omit the optional filesystem argument. For example, the dir command contains an optional filesystem argument and displays a list of files on a particular file system. When you omit this filesystem argument, the system shows a list of the files on the file system specified by the cd command. Examples The following example shows that the present working file system specified by the cd command is slot 0: Router> pwd slot0:/ The following example uses the cd command to change the present file system to slot 1 and then uses the pwd command to display that present working file system: Router> cd slot1: Router> pwd slot1:/ Related Commands Release Modification 11.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description cd Changes the default directory or file system. dir Displays a list of files on a file system. refuse-message CF-446 Cisco IOS Configuration Fundamentals Command Reference April 2010 refuse-message To define and enable a line-in-use message, use the refuse-message command in line configuration mode. To disable the message, use the no form of this command. refuse-message d message d no refuse-message Syntax Description Defaults Disabled (no line-in-use message is displayed). Command Modes Line configuration Command History Usage Guidelines Follow this command with one or more blank spaces and a delimiting character of your choice. Then enter one or more lines of text, terminating the message with the second occurrence of the delimiting character. You cannot use the delimiting character within the text of the message. When you define a message using this command, the Cisco IOS software performs the following steps: 1. Accepts the connection. 2. Prints the custom message. 3. Clears the connection. Examples In the following example, line 5 is configured with a line-in-use message, and the user is instructed to try again later: line 5 refuse-message /The dial-out modem is currently in use. Please try again later./ d Delimiting character of your choice—a pound sign (#), for example. You cannot use the delimiting character in the message. message Message text. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. reload CF-447 Cisco IOS Configuration Fundamentals Command Reference April 2010 reload To reload the operating system, use the reload command in privileged EXEC or diagnostic mode. reload [/verify | /noverify] [line | in [hhh:mm | mmm [text]] | at hh:mm [text] | reason [reason string] | cancel] Syntax Description Command Modes Privileged EXEC (#) Diagnostic (diag) Command History /verify (Optional) Verifies the digital signature of the file that will be loaded onto the operating system. /noverify (Optional) Does not verify the digital signature of the file that will be loaded onto the operating system. Note This keyword is often issued if the file verify auto command is enabled, which automatically verifies the digital signature of all images that are copied. line (Optional) Reason for reloading; the string can be from 1 to 255 characters long. in hhh:mm | mmm (Optional) Schedules a reload of the software to take effect in the specified minutes or hours and minutes. The reload must take place within approximately 24 days. text (Optional) Reason for reloading; the string can be from 1 to 255 characters long. at hh:mm (Optional) Schedules a reload of the software to take place at the specified time (using a 24-hour clock). If you specify the month and day, the reload is scheduled to take place at the specified time and date. If you do not specify the month and day, the reload takes place at the specified time on the current day (if the specified time is later than the current time) or on the next day (if the specified time is earlier than the current time). Specifying 00:00 schedules the reload for midnight. The reload must take place within 24 days. day (Optional) Number of the day in the range from 1 to 31. reason reason string (Optional) Used to specify a reason for reloading. cancel (Optional) Cancels a scheduled reload. Release Modification 10.0 This command was introduced. 12.2(14)SX Support for this command was added for the Supervisor Engine 720. 12.3(2)T The warm keyword was added. 12.2(18)S This command was integrated into Cisco IOS Release 12.2(18)S. The /verify and /noverify keywords were added. 12.2(20)S Support was added for the Cisco 7304 router. The Cisco 7500 series router in not supported in Cisco IOS Release 12.2(20)S. 12.0(26)S The /verify and /noverify keywords were integrated into Cisco IOS Release 12.0(26)S. reload CF-448 Cisco IOS Configuration Fundamentals Command Reference April 2010 Usage Guidelines The reload command halts the system. If the system is set to restart on error, it reboots itself. Use the reload command after configuration information is entered into a file and saved to the startup configuration. You cannot reload from a virtual terminal if the system is not set up for automatic booting. This restriction prevents the system from using an image stored in the ROM monitor and taking the system out of the remote user’s control. If you modify your configuration file, the system prompts you to save the configuration. During a save operation, the system prompts whether you want to proceed with the save if the CONFIG_FILE variable points to a startup configuration file that no longer exists. If you respond “yes” in this situation, the system enters setup mode upon reload. When you schedule a reload to occur at a later time (using the in keyword), it must take place within 24 days. The at keyword can be used only if the system clock has been set on the router (either through Network Time Protocol [NTP], the hardware calendar, or manually). The time is relative to the configured time zone on the router. To schedule reloads across several routers to occur simultaneously, synchronize the time on each router with NTP. When you specify the reload time using the at keyword, if you specify the month and day, the reload takes place at the specified time and date. If you do not specify the month and day, the reload takes place at the specified time on the current day (if the specified time is later than the current time), or on the next day (if the specified time is earlier than the current time). Specifying 00:00 schedules the reload for midnight. The reload must take place within 24 days. To display information about a scheduled reload, use the show reload command. The /verify and /noverify Keywords If the /verify keyword is specified, the integrity of the image will be verified before it is reloaded onto a router. If verification fails, the image reload will not occur. Image verification is important because it assures the user that the image is protected from accidental corruption, which can occur at any time during transit, starting from the moment the files are generated by Cisco until they reach the user. The /noverify keyword overrides any global automatic image verification that may be enabled via the file verify auto command. 12.3(4)T The /verify and /noverify keywords were integrated into Cisco IOS Release 12.3(4)T. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB. 12.3(11)T The file keyword and url argument were added. 12.2(28)SB This command was integrated into Cisco IOS Release 12.2(28)SB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 15.0(1)M The reason keyword and reason string argument were added. Cisco IOS XE Release 2.1 This command was introduced on the Cisco ASR 1000 Series Router and was made available in diagnostic mode. Release Modification reload CF-449 Cisco IOS Configuration Fundamentals Command Reference April 2010 The warm Keyword If you issue the reload command after you have configured the warm-reboot global configuration command, a cold reboot will occur. Thus, if you want to reload your system, but do not want to override the warm reboot functionality, you should specify the warm keyword with the reload command. The warm reboot functionality allows a Cisco IOS image to reload without ROM monitor intervention. That is, read-write data is saved in RAM during a cold startup and restored during a warm reboot. Warm rebooting allows the router to reboot quicker than conventional rebooting (where control is transferred to ROM monitor and back to the image) because nothing is copied from flash to RAM. Examples The following example shows how to immediately reload the software on the router: Router# reload The following example shows how to reload the software on the router in 10 minutes: Router# reload in 10 Router# Reload scheduled for 11:57:08 PDT Fri Apr 21 1996 (in 10 minutes) Proceed with reload?

Related Commands Command Description request platform software package install file Upgrades an individual package or a superpackage file. request platform software package expand file CF-463 Cisco IOS Configuration Fundamentals Command Reference April 2010 request platform software package expand file To extract the individual modules from a Cisco IOS-XE image, use the request platform software package expand file command in privileged EXEC or diagnostic mode. request platform software package expand file source-URL [to destination-URL] [force] [verbose] [wipe] Syntax Description Command Default No default behavior or values Command Modes Privileged EXEC (#) Diagnostic Mode (diag) Command History Usage Guidelines This command only extracts individual module files and a provisioning file from the Cisco IOS-XE image. Additional configuration is needed to configure the router to boot using the provisioning files and run using the individual modules. When this command is used, copies of each module and the provisioning file within the Cisco IOS-XE image are copied and placed on the destination directory. The Cisco IOS-XE image file is unchanged after the operation is complete. If the to destination-URL option is not entered, the Cisco IOS-XE image contents will be extracted onto the same directory where the Cisco IOS-XE image is currently stored. If this command is used to extract individual module files onto a directory that already contains individual module files, the files that would have been extracted onto the same directory are instead extracted to an automatically created directory on the destination device. source-URL Specifies the URL to the Cisco IOS-XE file that stores the contents that will be extracted. to destination-URL Specifies the destination URL where the files that were extracted from the Cisco IOS-XE file are left after the operation is complete. If this option is not entered, the Cisco IOS-XE image file contents are extracted onto the same directory where the Cisco IOS-XE image file is currently stored. force (Optional) Specifies that the operation will be forced, meaning that the upgrade will proceed despite any warning messages. verbose (Optional) Displays verbose information, meaning all output that can be displayed on the console during the process will be displayed. wipe (Optional) Erases all content on the destination snapshot directory before extracting the files and placing them on the snapshot directory. Release Modification IOS XE Release 2.1 This command was introduced. request platform software package expand file CF-464 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following example shows how to extract the individual modules and the provisioning file from a Cisco IOS-XE image that has already been placed in the directory where the user wants to store the individual modules and the provisioning file.

Command Modes Privileged EXEC (#) Diagnostic Mode (diag) Command History Usage Guidelines This command is entered after the request platform software package install rp rp-slot-number file command is used with the auto-rollback minutes option to begin an individual sub-package or a consolidated package upgrade. When the auto-rollback minutes option is used in this context, a rollback timer that cancels the upgrade after the number of specified minutes cancels the upgrade if the request platform software package install rp rp-slot-number commit command is not entered to commit the upgrade. If this command is not entered after the request platform software package install rp rp-slot-number file command is used with the auto-rollback minutes option to upgrade an individual sub-package or a consolidated package and the rollback timer expires, the upgrade does not complete and the router continues running the previous sub-package or consolidated package. Examples In the following example, this command is entered to commit an upgrade: request platform software package install rp 1 commit rp rp-slot-number Specifies the RP slot number. commit Specifies that an upgrade that was done using a rollback timer that has not expired can be committed. verbose (Optional) Displays verbose information, meaning all information that can be displayed on the console during the process will be displayed.

When you are in ROMmon, there is no descriptive output to inform you whether the ReadOnly ROMmon image was reloaded. To confirm the reload, use the showmon command after entering the rommon-pref readonly command. Use this command when you are in ROMmon mode. Use the upgrade rom-monitor preference command when you are in Cisco IOS. Examples The following example, applicable to both the Cisco 7200 VXR and Cisco 7301 routers, shows how to select the ReadOnly ROMmon image to be booted on the next reload of the router when you are already in ROMmon mode: rommon 2 > rommon-pref readonly readonly Selects the ReadOnly ROMmon image to be booted on the next reload. upgrade Selects the Upgrade, second ROMmon image to be booted on the next reload.

As the default value of the remote username, the software sends the username associated with the current tty process, if that name is valid. For example, if the user is connected to the router through Telnet and the user was authenticated through the username command, then the software sends that username as the remote username. If the tty username is invalid, the software uses the host name as the both the remote and local usernames. Note For Cisco, tty lines are commonly used for access services. The concept of tty originated with UNIX. For UNIX systems, each physical device is represented in the file system. Terminals are sometimes called tty devices (tty stands for teletype, the original UNIX terminal). Command Modes Privileged EXEC Command History Usage Guidelines Use the rsh command to execute commands remotely. The host on which you remotely execute the command must support the rsh protocol, and the .rhosts files on the rsh host must include an entry that permits you to remotely execute commands on that host. For security reasons, the software does not default to a remote login if no command is specified, as does UNIX. Instead, the router provides Telnet and connect services that you can use rather than rsh. ip-address IP address of the remote host on which to execute the rsh command. Either the IP address or the host name is required. host Name of the remote host on which to execute the command. Either the host name or the IP address is required. /user username (Optional) Remote username. remote-command Command to be executed remotely. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. rsh CF-497 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following command specifies that the user named sharon attempts to remotely execute the UNIX ls command with the -a argument on the remote host named mysys.cisco.com.

To restore the default, use the no form of this command. scheduler allocate interrupt-time process-time no scheduler allocate Syntax Description Defaults Approximately 5 percent of the CPU is available for process tasks. Command Modes Global configuration Command History Usage Guidelines This command applies to the Catalyst 6500 series switches, Cisco 7200 series, Cisco 7500 series, and Cisco 7600 series routers. Caution We recommend that you do not change the default settings. Changing settings associated with CPU processes can negatively impact system performance. Entering the scheduler allocate command without arguments is the same as entering the no scheduler allocate or the default scheduler allocate command. interrupt-time Integer (in microseconds) that limits the maximum number of microseconds to spend on fast switching within any one network interrupt context.

To restore the default, use the no form of this command. scheduler interval milliseconds no scheduler interval Syntax Description Defaults High-priority operations are allowed to use as much of the CPU as needed. Command Modes Global configuration Command History Usage Guidelines The normal operation of the network server allows the switching operations to use as much of the central processor as is required. If the network is running unusually heavy loads that do not allow the processor the time to handle the routing protocols, give priority to the system process scheduler. High-priority operations are allowed to use as much of the CPU as needed. Note Changing settings associated with CPU processes can negatively impact system performance. On the Cisco 7200 series and Cisco 7500 series, use the scheduler allocate global configuration command instead of the scheduler interval command. Examples The following example changes the low-priority process schedule to an interval of 750 milliseconds: Router(config)# scheduler interval 750 Related Commands milliseconds Integer that specifies the interval (in milliseconds). The minimum interval that you can specify is 500 milliseconds; there is no maximum value. Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description scheduler allocate Guarantees CPU time for processes. send CF-506 Cisco IOS Configuration Fundamentals Command Reference April 2010 send To send messages to one or all terminal lines, use the send command in EXEC mode. send {line-number | * | aux number | console number | tty number | vty number} Syntax Description Defaults No messages are sent. Command Modes User EXEC Priviledged EXEC Command History Usage Guidelines After entering this command, the system prompts for the message to be sent, which can be up to 500 characters long. Enter Ctrl-Z to end the message. Enter Ctrl-C to abort this command. Caution Be aware that in some circumstances text sent using the send command may be interpreted as an executable command by the receiving device. For example, if the receiving device is Unix workstation, and the receiving device is in a state (shell) where commands can be executed, the incoming text, if a properly formated Unix command, will be accepted by the workstation as a command. For this reason, you should limit your exposure to potential messages from terminal servers or other Cisco IOS-based devices when running an interactive shell. Examples The following example sends a message to all lines: 2509# send * Enter message, end with CTRL/Z; abort with CTRL/C: The system 2509 will be shut down in 10 minutes for repairs.^Z Send message? [confirm] 2509# line-number Line number to which the message will be sent. * Sends a message to all lines. aux number Sends a message to the specified AUX port. console number Sends a message to the specified console port. tty number Sends a message to the specified asynchronous line. vty number Sends a message to the specified virtual asynchronous line.

To disable compression, use the no form of this command. service compress-config no service compress-config Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines After you configure the service compress-config command, the router will compress configuration files every time you save a configuration to the startup configuration. For example, when you enter the copy system:running-config nvram:startup-config command, the running configuration will be compressed before storage in NVRAM. If the file compression succeeds, the following message is displayed: Compressing configuration from configuration-size to compressed-size [OK] If the boot ROMs do not recognize a compressed configuration, the following message is displayed: Boot ROMs do not support NVRAM compression Config NOT written to NVRAM If the file compression fails, the following message is displayed: Error trying to compress nvram One way to determine whether a configuration file will be compressed enough to fit into NVRAM is to use a text editor to enter the configuration, then use the UNIX compress command to check the compressed size. To get a closer approximation of the compression ratio, use the UNIX compress -b12 command. Once the configuration file has been compressed, the router functions normally. At boot time, the system recognizes that the configuration file is compressed, uncompresses it, and proceeds normally. A partition nvram:startup-config command uncompresses the configuration before displaying it. To disable compression of the configuration file, enter configuration mode and specify the no service compress-config command. Then, exit global configuration mode and enter the copy system:running-config nvram:startup-config command. The router displays an OK message if it is Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service compress-config CF-509 Cisco IOS Configuration Fundamentals Command Reference April 2010 able to write the uncompressed configuration to NVRAM. Otherwise, the router displays an error message indicating that the configuration is too large to store. If the configuration file is larger than the physical NVRAM, the following message is displayed: ##Configuration too large to fit uncompressed in NVRAM Truncate configuration? [confirm] When the file is truncated, commands at the end of the file are erased. Therefore, you will lose part of your configuration. To truncate and save the configuration, type Y. To not truncate and not save the configuration, type N. Examples In the following example, the configuration file is compressed: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# service compress-config Router(config)# end Router# %SYS-5-CONFIG_I: Configured from console by console Router# copy system:running-config nvram:startup-config Building configuration... Compressing configuration from 1179 bytes to 674 bytes [OK] Related Commands Command Description partition nvram:startup-config Separates Flash memory into partitions on Class B file system platforms. service config CF-510 Cisco IOS Configuration Fundamentals Command Reference April 2010 service config To enable autoloading of configuration files from a network server, use the service config command in global configuration mode. To restore the default, use the no form of this command. service config no service config Syntax Description This command has no arguments or keywords. Defaults Disabled, except on systems without NVRAM or with invalid or incomplete information in NVRAM. In these cases, autoloading of configuration files from a network server is enabled automatically. Command Modes Global configuration Command History Usage Guidelines Usually, the service config command is used in conjunction with the boot host or boot network command. You must enter the service config command to enable the router to automatically configure the system from the file specified by the boot host or boot network command. With IOS software versions 12.3(2)T , 12.3(1)B, and later, you no longer have to specify the service config command for the boot host or boot network command to be active. If you specify both the no service config command and the boot host command, the router attempts to find the specified host configuration file. The service config command can also be used without the boot host or boot network command. If you do not specify host or network configuration filenames, the router uses the default configuration files. The default network configuration file is network-confg. The default host configuration file is host-confg, where host is the hostname of the router. If the Cisco IOS software cannot resolve its hostname, the default host configuration file is router-confg. Examples In the following example, a router is configured to autoload the default network and host configuration files. Because no boot host or boot network commands are specified, the router uses the broadcast address to request the files from a TFTP server. Router(config)# service config Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service config CF-511 Cisco IOS Configuration Fundamentals Command Reference April 2010 The following example changes the network configuration filename to bridge_9.1, specifies that rcp is to be used as the transport mechanism, and gives 172.16.1.111 as the IP address of the server on which the network configuration file resides: Router(config)# service config Router(config)# boot network rcp://172.16.1.111/bridge_9.1 Related Commands Command Description boot host Changes the default name of the host configuration filename from which to load configuration commands. boot network Changes the default name of the network configuration file from which to load configuration commands. service counters max age CF-512 Cisco IOS Configuration Fundamentals Command Reference April 2010 service counters max age To set the time interval for retrieving statistics, use the service counters max age command in global configuration mode. To return to the default settings, use the no form of this command. service counters max age seconds no service counters max age Syntax Description Defaults seconds is 5 seconds. Command Modes Global configuration Command History Usage Guidelines A fully loaded Catalyst 6500 series switch chassis running Cisco IOS software version 12.2(18)SXF or its minor variants (SXF through SXF5) takes 1-2 minutes to update the SNMP counters maintained under ifTable and ifXTable. Polling the ifTable/ifXTable is done with the need to understand how much traffic is being handled by a specific port/interface. The typical polling interval to meet this need is 3-5 minutes. No gain is achived by reducing the polling interval to intervals lesser than 3 minutes. Note If you decrease the time interval for retrieving statistics from the default setting (5 seconds), traffic congestion may result in situations where frequent SNMP (SMNP bulk) retrievals occur. Examples This example shows how to set the time interval for retrieving statistics: Router(config)# service counters max age 10 Router(config)# seconds Maximum age, in seconds, of the statistics retrieved from the CLI or SNMP; valid values are from 0 to 60 seconds. Release Modification 12.2(18)SXD Support for this command was introduced on the Supervisor Engine 720 and the Supervisor Engine 2. 12.2(18)SXF This command was changed as follows: • The default was changed from 10 seconds to 5 seconds. • The valid values for seconds was changed from 1 to 60 seconds to 0 to 60 seconds. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service counters max age CF-513 Cisco IOS Configuration Fundamentals Command Reference April 2010 This example shows how to return to the default setting: Router(config)# no service counters max age Router(config)# service decimal-tty CF-514 Cisco IOS Configuration Fundamentals Command Reference April 2010 service decimal-tty To specify that line numbers be displayed and interpreted as octal numbers rather than decimal numbers, use the no service decimal-tty command in global configuration mode. To restore the default, use the service decimal-tty command. service decimal-tty no service decimal-tty Syntax Description This command has no arguments or keywords. Defaults Enabled (line numbers displayed as decimal numbers) Command Modes Global configuration Command History Examples In the following example, the router is configured to display decimal rather than octal line numbers: Router(config)# service decimal-tty Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service exec-wait CF-515 Cisco IOS Configuration Fundamentals Command Reference April 2010 service exec-wait To delay the startup of the EXEC on noisy lines, use the service exec-wait command in global configuration mode. To disable the delay function, use the no form of this command. service exec-wait no service exec-wait Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines This command delays startup of the EXEC until the line has been idle (no traffic seen) for 3 seconds. The default is to enable the line immediately on modem activation. This command is useful on noisy modem lines or when a modem attached to the line is configured to ignore MNP/V.42 negotiations, and MNP/V.42 modems may be dialing in. In these cases, noise or MNP/V.42 packets may be interpreted as usernames and passwords, causing authentication failure before the user has a chance to type a username or password. The command is not useful on nonmodem lines or lines without some kind of login configured. Examples The following example delays the startup of the EXEC: Router(config)# service exec-wait Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service finger CF-516 Cisco IOS Configuration Fundamentals Command Reference April 2010 service finger The service finger command has been replaced by the ip finger command. However, the service finger and no service finger commands continue to function to maintain backward compatibility with older versions of Cisco IOS software. Support for this command may be removed in a future release. See the description of the ip finger command for more information. service hide-telnet-address CF-517 Cisco IOS Configuration Fundamentals Command Reference April 2010 service hide-telnet-address To hide addresses while trying to establish a Telnet session, use the service hide-telnet-address command in global configuration mode. To disable this service, use the no form of this command. service hide-telnet-address no service hide-telnet-address Syntax Description This command has no arguments or keywords. Defaults Addresses are displayed. Command Modes Global configuration Command History Usage Guidelines When you attempt to connect to a device, the router displays addresses and other messages (for example, “Trying router1 (171.69.1.154, 2008)...).” With the hide feature, the router suppresses the display of the address (for example, “Trying router1 address #1...”). The router continues to display all other messages that would normally be displayed during a connection attempt, such as detailed error messages if the connection was not successful. The hide feature improves the functionality of the busy-message feature. When you configure only the busy-message command, the normal messages generated during a connection attempt are not displayed; only the busy-message is displayed. When you use the hide and busy features together you can customize the information displayed during Telnet connection attempts. When you configure the service hide-telnet-address command and the busy-message command, the router suppresses the address and displays the message specified with the busy-message command if the connection attempt is not successful. Examples The following example hides Telnet addresses: Router(config)# service hide-telnet-address Related Commands Release Modification 11.2 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description busy-message Creates a “host failed” message that is displayed when a connection fails. service linenumber CF-518 Cisco IOS Configuration Fundamentals Command Reference April 2010 service linenumber To configure the Cisco IOS software to display line number information after the EXEC or incoming banner, use the service linenumber command in global configuration mode. To disable this function, use the no form of this command. service linenumber no service linenumber Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines With the service linenumber command, you can have the Cisco IOS software display the host name, line number, and location each time an EXEC process is started, or an incoming connection is made. The line number banner appears immediately after the EXEC banner or incoming banner. This feature is useful for tracking problems with modems, because the host and line for the modem connection are listed. Modem type information can also be included. Examples In the following example, a user Telnets to Router2 before and after the service linenumber command is enabled. The second time, information about the line is displayed after the banner. Router1> telnet Router2 Trying Router2 (172.30.162.131)... Open Welcome to Router2. User Access Verification Password: Router2> enable Password: Router2# configure terminal Enter configuration commands, one per line. End with CNTL/Z.

To disable the algorithm, use the no form of this command. service nagle no service nagle Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines When using a standard TCP implementation to send keystrokes between machines, TCP tends to send one packet for each keystroke typed. On larger networks, many small packets use up bandwidth and contribute to congestion. The algorithm developed by John Nagle (RFC 896) helps alleviate the small-packet problem in TCP. In general, it works this way: The first character typed after connection establishment is sent in a single packet, but TCP holds any additional characters typed until the receiver acknowledges the previous packet. Then the second, larger packet is sent, and additional typed characters are saved until the acknowledgment comes back. The effect is to accumulate characters into larger chunks, and pace them out to the network at a rate matching the round-trip time of the given connection. This method is usually effective for all TCP-based traffic. However, do not use the service nagle command if you have XRemote users on X Window system sessions. Examples The following example enables the Nagle algorithm: Router(config)# service nagle Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service prompt config CF-521 Cisco IOS Configuration Fundamentals Command Reference April 2010 service prompt config To display the configuration prompt (config), use the service prompt config command in global configuration mode. To remove the configuration prompt, use the no form of this command. service prompt config no service prompt config Syntax Description This command has no arguments or keywords. Defaults The configuration prompts appear in all configuration modes. Command Modes Global configuration Command History Examples In the following example, the no service prompt config command prevents the configuration prompt from being displayed. The prompt is still displayed in EXEC mode. When the service prompt config command is entered, the configuration mode prompt reappears.

To disable visible sequence numbering of logging messages, use the no form of this command. service sequence-numbers no service sequence-numbers Syntax Description This command has no arguments or keywords. Defaults Disabled. Command Modes Global configuration Command History Usage Guidelines Each system status messages logged in the system logging process have a sequence reference number applied. This command makes that number visible by displaying it with the message. The sequence number is displayed as the first part of the system status message. See the description of the logging commands for information on displaying logging messages. Examples In the following example logging message sequence numbers are enabled: .Mar 22 15:28:02 PST: %SYS-5-CONFIG_I: Configured from console by console Router# config terminal Enter configuration commands, one per line. End with CNTL/Z.

To disable these services, use the no form of the command. service tcp-small-servers no service tcp-small-servers Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines By default, the TCP servers for Echo, Discard, Chargen, and Daytime services are disabled. When the minor TCP/IP servers are disabled, access to the Echo, Discard, Chargen, and Daytime ports cause the Cisco IOS software to send a TCP RESET packet to the sender and discard the original incoming packet. Examples The following example enables minor TCP/ IP services available from the network: Router(config)# service tcp-small-servers Release Modification 11.1 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service telnet-zero-idle CF-527 Cisco IOS Configuration Fundamentals Command Reference April 2010 service telnet-zero-idle To set the TCP window to zero (0) when the Telnet connection is idle, use the service telnet-zero-idle command in global configuration mode. To disable this service, use the no form of this command. service telnet-zero-idle no service telnet-zero-idle Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines Normally, data sent to noncurrent Telnet connections is accepted and discarded. When the service telnet-zero-idle command is enabled, if a session is suspended (that is, some other connection is made active or the EXEC is sitting in command mode), the TCP window is set to zero. This action prevents the remote host from sending any more data until the connection is resumed. Use this command when it is important that all messages sent by the host be seen by the users and the users are likely to use multiple sessions. Do not use this command if your host will eventually time out and log out a TCP user whose window is zero. Examples The following example sets the TCP window to zero when the Telnet connection is idle: Router(config)# service telnet-zero-idle Related Commands Release Modification 10.0 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. Command Description resume Switches to another open Telnet, rlogin, LAT, or PAD session. service timestamps CF-528 Cisco IOS Configuration Fundamentals Command Reference April 2010 service timestamps To configure the system to apply a time stamp to debugging messages or system logging messages, use the service timestamps command in global configuration mode. To disable this service, use the no form of this command. service timestamps [debug | log] [uptime | datetime [msec]] [localtime] [show-timezone] [year] no service timestamps [debug | log] Syntax Description debug (Optional) Indicates time-stamping for debugging messages. log (Optional) Indicates time-stamping for system logging messages. uptime (Optional) Specifies that the time stamp should consist of the time since the system was last rebooted. For example “4w6d” (time since last reboot is 4 weeks and 6 days). • This is the default time-stamp format for both debugging messages and logging messages. • The format for uptime varies depending on how much time has elapsed: – HHHH:MM:SS (HHHH hours: MM minutes: SS seconds) for the first 24 hours – DdHHh (D days HH hours) after the first day – WwDd (W weeks D days) after the first week datetime (Optional) Specifies that the time stamp should consist of the date and time. • The time-stamp format for datetime is MMM DD HH:MM:SS, where MMM is the month, DD is the date, HH is the hour (in 24-hour notation), MM is the minute, and SS is the second. • If the datetime keyword is specified, you can optionally add the msec localtime, show-timezone, or year keywords. • If the service timestamps datetime command is used without addtional keywords, time stamps will be shown using UTC, without the year, without milliseconds, and without a time zone name. msec (Optional) Includes milliseconds in the time stamp, in the format HH:DD:MM:SS.mmm, where .mmm is milliseconds localtime (Optional) Time stamp relative to the local time zone. year (Optional) Include the year in the date-time format. show-timezone (Optional) Include the time zone name in the time stamp. Note If the localtime keyword option is not used (or if the local time zone has not been configured using the clock timezone command), time will be displayed in Coordinated Universal Time (UTC). service timestamps CF-529 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Default Time stamps are applied to debug and logging messages. Command Modes Global configuration (config) Command History Usage Guidelines Time stamps can be added to either debugging messages (service timestamp debug) or logging messages (service timestamp log) independently. If the service timestamps command is specified with no arguments or keywords, the default is service timestamps debug uptime. The no service timestamps command by itself disables time stamps for both debug and log messages. The uptime form of the command adds time stamps (such as “2w3d”) that indicating the time since the system was rebooted. The datetime form of the command adds time stamps (such as “Sep 5 2002 07:28:20”) that indicate the date and time according to the system clock. Entering the service timestamps {debug | log} command a second time will overwrite any previously configured service timestamp {debug | log} commands and associated options. To set the local time zone, use the clock timezone zone hours-offset command in global configuration mode. The time stamp will be preceeded by an asterisk or period if the time is potentially inaccurate. Table 48 describes the symbols that proceed the time stamp. Release Modification 10.0 This command was introduced. 11.3(5) Service time stamps are enabled by default. 12.3(1) The year keyword was added. 12.3(2)T This command was integrated into Cisco IOS Release 12.3(2)T. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. 12.2(33)SB This command was integrated into Cisco IOS Release 12.2(33)SB.

To disable these services, use the no form of this command. service udp-small-servers no service udp-small-servers Syntax Description This command has no arguments or keywords. Defaults Disabled Command Modes Global configuration Command History Usage Guidelines By default the UPD servers for Echo, Discard, and Chargen services are disabled. When the servers are disabled, access to Echo, Discard, and Chargen ports causes the Cisco IOS software to send an “ICMP port unreachable” message to the sender and discard the original incoming packet. Examples In the following example, the UDP server (UDP services) is enabled: Router(config)# service udp-small-servers Release Modification 11.2 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. service-module apa traffic-management CF-534 Cisco IOS Configuration Fundamentals Command Reference April 2010 service-module apa traffic-management To configure traffic management on the router, use the service-module apa traffic-management command in interface configuration mode. service-module apa traffic-management [ monitor | inline ] Syntax Description Command Default None Command Modes Interface configuration mode Command History Usage Guidelines To perform traffic management, you enable or disable the flow of packets by configuring the service module interface and the router interface. • Configure the router interface with the service-module apa traffic-management [monitor | inline] command. Two traffic management options are available: – Monitor—will copy the packet and designate the copy as the one forwarded to the Application Performance Assurance module (NME-APA). – Inline—will send the packet to the NME-APA, rather than sending a copy of the packet. After the NME-APA has processes the packet, it sends it back to the router. Note Enable only one traffic management option on the router, but not both concurrently. • Configure the service module interface with the Application Performance Assurance (APA) graphical user interface (GUI). See the Cisco Application Performance Assurance User Guide on Cisco.com for details. monitor Enables promiscuous monitoring. inline Enables inline monitoring. Release Modification 12.4(20)YA This command was introduced for the NME-APA on Cisco 2811, 2821, 2851, and Cisco 3800 Series Integrated Services Routers. service-module apa traffic-management CF-535 Cisco IOS Configuration Fundamentals Command Reference April 2010 Examples The following example configures an interface on a Cisco 2851 Integrated Services Router for inline traffic management.

After enabling the unified image, use the service-module wlan-ap 0 reload command to perform a graceful shutdown and reboot of the access point. Note The service-module wlan-ap 0 bootimage command does not support recovery images on the embedded access point. Use the service-module wlan-ap 0 reload command to shutdown and reboot the access point. Cisco 880 Series and Cisco 890 Series routers with embedded access point running the unified software image require DHCP to obtain an IP address for the access point. An IP address is needed to communicate with the Wireless LAN Controller (WLC) and to download its image upon boot up. The host router can provide DHCP server functionality through the DHCP pool to reach the WLC, and setup option 43 for the controller IP address in the DHCP pool configuration. Use the following guideline to setup a DHCP pool on the host router. ip dhcp pool embedded-ap-pool network 60.0.0.0 255.255.255.0 default router 60.0.0.1 option 43 hex f104.0a0a.0a0f /* Single WLC IP address (10.10.10.15) in HEX format */ int vlan 1 /* Default Vlan */ ip address 60.0.0.1 255.255.255.0 int Wlan-GigabitEthernet0 /* internal switch-port to AP */ switchport access vlan 1 interface number The interface number for the wireless device.

Command Modes Privileged EXEC Command History Usage Guidelines Setup mode gives you the option of configuring your system without using the Cisco IOS Command Line Interface (CLI). For some tasks, you may find it easier to use Setup than to enter Cisco IOS commands individually. For example, you might want to use Setup to add a protocol suite, to make major addressing scheme changes, or to configure a newly installed interface. Although you can use the CLI to make these changes, Setup provides you with a high-level view of the configuration and guides you through the configuration process. If you are not familiar with Cisco products and the CLI, Setup is a particularly valuable tool because it prompts you for the specific information required to configure your system. Note If you use the Setup mode to modify a configuration because you have added or modified the hardware, be sure to verify the physical connections using the show version EXEC command. Also, verify the logical port assignments using the show running-config EXEC command to ensure that you configure the correct port. Refer to the hardware documentation for your platform for more information on physical and logical port assignments. Before using the Setup mode, you should have the following information so that you can configure the system properly: • Which interfaces you want to configure • Which routing protocols you wish to enable • Whether the router is to perform bridging • Network addresses for the protocols being configured • Password strategy for your environment When you enter the setup EXEC command after first-time startup, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. It prompts you first for global parameters and then for interface parameters. The values shown in brackets next to each prompt reflect either the default settings or the last configured setting. Release Modification 11.1 This command was introduced. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. setup CF-549 Cisco IOS Configuration Fundamentals Command Reference April 2010 The prompts and the order in which they appear on the screen vary depending on the platform and the interfaces installed in the device. You must progress through the System Configuration Dialog until you come to the item that you intend to change. To accept default settings for items that you do not want to change, press the Return or Enter key. The default choice is indicated by square brackets (for example, [yes]) before the prompt colon (:). To exit Setup mode and return to privileged EXEC mode without making changes and without progressing through the entire System Configuration Dialog, press Ctrl-C. The facility also provides help text for each prompt. To access help text, press the question mark (?) key at a prompt. When you complete your changes, the system will automatically display the configuration file that was created during the Setup session. It also asks you if you want to use this configuration. If you answer Yes, the configuration is saved to NVRAM as the startup configuration file. If you answer No, the configuration is not saved and the process begins again. There is no default for this prompt; you must answer either Yes or No. Examples The following example displays the setup command facility to configure serial interface 0 and to add ARAP and IP/IPX PPP support on the asynchronous interfaces: Router# setup --- System Configuration Dialog --- At any point you may enter a question mark '?' for help.

This command adds the show command output to the end of the specified file. Examples In the following example, output from the show tech-support command is redirected to an existing file on Disk 1 with the file-name of “showoutput.txt.” This output is added at the end of any existing data in the file. Router# show tech-support | append disk1:showoutput.txt Related Commands command Any Cisco IOS show command. | append url The addition of this syntax redirects the command output to the file location specified in the Universal Resource Locator (URL). The pipe (|) is required. The Cisco IOS File System (IFS) uses URLs to specify the location of a file system, directory, and file. Typical URL elements include: prefix:[directory/]filename Prefixes can be local file locations, such as flash: or disk0:. Alternatively, you can specify network locations using the following syntax: ftp:[[//[username[:password]@]location]/directory]/filename tftp:[[//location]/directory]/filename The rcp: prefix is not supported.

Use parenthesis to indicate a literal use of spaces. For example, | begin u indicates that the show output should begin with any line that contains a u; | begin ( u) indicates that the show output should begin with any line that contains a space and a u together (line has a word that begins with a lowercase u). To search the remaining output of the show command, use the following command at the --More-- prompt: /regular-expression You can specify a filtered search at any --More-- prompt. To filter the remaining output of the show command, use one of the following commands at the --More-- prompt: -regular-expression +regular-expression When output volume is large, the search can produce long lists of output. To interrupt the output, press Ctrl-^ (Ctrl-Shift-6) or Ctrl-z. command Any supported show command. | A vertical bar (the “pipe” symbol) indicates that an output processing specification follows. regular-expression Any regular expression found in show command output.

The first specified filter remains until the more command output finishes or until you interrupt the output. The use of the keyword begin does not constitute a filter. Because prior output is not saved, you cannot search or filter backward through prior output. Note A few show commands that have long output requirements do not require user input at the --More-- prompt to jump to the next table of output; these types of output require you to enter the same number of Ctrl-^ or Ctrl-Z combinations as there are --More-- prompts to completely abort output. Examples The following is partial sample output of the show interface | begin command that begins unfiltered output with the first line that contains the regular expression “Ethernet.” At the --More-- prompt, the user specifies a filter to show only the lines in the remaining output that contain the regular expression “Serial.” Router# show interface | begin Ethernet Ethernet0 is up, line protocol is up Hardware is Lance, address is 0060.837c.6399 (bia 0060.837c.6399) Description: ip address is 172.1.2.14 255.255.255.0 Internet address is 172.1.2.14/24 . . . 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out --More-- +Serial filtering...

Filtering provides some control over the type and amount of information displayed by the system. The show section command provides enhanced filtering capabilities by matching lines in the show command output containing specific expressions as well as matching any entries associated with those expressions. Filtering is especially useful, for example, when displaying large configuration files using the show running-configuration command or the show interfaces command. If the include or exclude keyword is not specified, include is the default. If there are no associated entries for an expression, then only the line matching the expression is displayed. Examples The following examples compare the filtering characteristics of the show running-config | include command with the show running-config | section command. The first example gathers just the lines from the configuration file with “interface” in them. Router# show running-config | include interface interface Ethernet0/0 interface Ethernet1/0 interface Serial2/0 interface Serial3/0 The next example uses the show command section command to gather the lines in the configuration file with “interface” in them as well as any lines associated with those entries. In this example, interface configuration information is captured. command Any Cisco IOS show command. include (Optional) Includes only the lines that contain a particular regular expression. This is the default keyword when none is specified. exclude (Optional) Excludes any lines that contain a particular regular expression. regular-expression Any regular expression or plain text string found in show command output. The syntax of the regular expression conforms to that of Bell V8 regexp(3).

The tee keyword was chosen to reflect that output is redirected to two locations; the terminal and a file (as a tee plumbing junction redirects water to two different pipes). Examples In the following example, output from the show tech-support command is displayed on-screen while it is written to the file “showoutput.txt” at the host 172.16.101.101 using TFTP: Router# show tech-support | tee tftp://172.16.101.101/docs/showoutput.txt The following example performs the same function as above, but in this case the output is added at the end of any existing data in the file “showoutput.txt”: Router# show tech-support | tee /append tftp://172.16.101.101/docs/showoutput.txt command Any Cisco IOS show command. | tee url The addition of this syntax copies the command output to the file location specified in the Universal Resource Locator (URL).

Command Description alias Creates a command alias. show alignment CF-579 Cisco IOS Configuration Fundamentals Command Reference April 2010 show alignment To display alignment errors and spurious memory access errors, use the show alignment command in privileged EXEC mode. show alignment Syntax Description This command has no arguments or keywords. Command Modes Privileged EXEC Command History Usage Guidelines Alignment Errors Alignment errors are caused by misaligned reads and writes. For example, a two-byte read where the memory address is not an even multiple of two bytes is an alignment error. Alignment errors are caused by a software defect. Alignment errors are reported in the system log and recorded by the router. Output from the show alignment command provides a record of these errors along with potentially useful traceback information. The traceback information for alignment errors can generally be decoded to reveal the function causing the alignment problems. Spurious Memory Access Errors Spurious memory access errors occur when a software process attempts to access memory in a restricted location. A read operation to this region of memory is usually caused when a nonexisting value is returned to a function in the software, or in other words, when a null pointer is passed to a function. Spurious memory access errors are counted and recorded, if possible, by the software. This information is displayed with the show alignment command. Examples The following is sample output from the show alignment command when alignment detection is disabled. To enable alignment detection, use the enable command to enter privileged EXEC mode Router# show alignment Unaligned handler is disabled Router# The following is sample output from the show alignment command when there are no alignment or spurious memory errors: Router# show alignment Release Modification 12.3(7)T This command was introduced. 12.2(22)S This command was integrated into Cisco IOS Release 12.2(22)S. 12.2(18)SXE This command was integrated into Cisco IOS Release 12.2(18)SXE. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. show alignment CF-580 Cisco IOS Configuration Fundamentals Command Reference April 2010 No alignment data has been recorded.

Command Modes User EXEC Privileged EXEC Command History Usage Guidelines Supported Platforms Other than the Cisco 7600 Series Router The show bootvar command replaces the show boot command. The show bootvar command allows you to view the current settings for the following variables: • BOOT • CONFIG_FILE • BOOTLDR The BOOT variable specifies a list of bootable images on various devices. The CONFIG_FILE variable specifies the configuration file used during system initialization. The BOOTLDR variable specifies the flash device and filename containing the rxboot image that ROM uses for booting. You set these variables with the boot system, boot config, and boot bootldr global configuration commands, respectively. When you use this command on a device with multiple Route Switch Processor (RSP) cards (Dual RSPs), this command also shows you the variable settings for both the master and slave RSP card. Cisco 7600 Series Router The show bootvar command displays information about the BOOT environmental variable. The command output depends on how you configure the boot statement as follows: • If you enter the boot system flash bootflash:sup720_image command in the boot configuration, then the show bootvar command output displays the bootflash information. Release Modification 11.3 AA This command was introduced. 12.2(14)SX Support for this command was implemented on the Supervisor Engine 720. 12.2(17d)SXB Support for this command on the Supervisor Engine 2 was integrated into Release 12.2(17d)SXB. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. show bootvar CF-601 Cisco IOS Configuration Fundamentals Command Reference April 2010 • If you enter the boot system flash sup-bootflash:sup720_image command in the boot configuration, then the show bootvar command output displays the sup-bootflash information. This action is the correct way of configuring the boot statement. The show bootvar command is available from the switch processor command-line interface (CLI) and the route processor CLI. From the switch processor CLI, the display is always bootflash. With either the bootflash or the sup-bootflash boot statement, the switch boots correctly. You should use sup-bootflash in the boot configuration statement because the image is stored in the switch processor bootflash; the route processor sees the image as sup-bootflash. The number displayed after the image name (for example, c6sup12-js-mz.121-13.E,12) indicates the number of times that the Cisco 7600 series router tries to reboot the file before giving up. Examples Supported Platforms Other than the Cisco 7600 Series Router The following is sample output from the show bootvar command: Router# show bootvar BOOT variable = CONFIG_FILE variable = nvram: Current CONFIG_FILE variable = slot0:router-config BOOTLDR variable not exist Configuration register is 0x0 In this example, the BOOT variable contains a null string; that is no bootable images are specified. The CONFIG_FILE variable points to the configuration file in NVRAM as the startup (initialization) configuration. The run-time value for the CONFIG_FILE variable points to the router-configuration file on the flash memory card inserted in the first slot of the RSP card. That is, during the run-time configuration, you have modified the CONFIG_FILE variable using the boot config command, but you have not saved the run-time configuration to the startup configuration. To save your run-time configuration to the startup configuration, use the copy system:running-config nvram:startup-config command. If you do not save the run-time configuration to the startup configuration, then the system reverts to the saved CONFIG_FILE variable setting for initialization information upon reload. In this sample, the system reverts to NVRAM for the startup configuration file. The BOOTLDR variable does not yet exist. That is, you have not created the BOOTLDR variable using the boot bootldr global configuration command. The following example is output from the show bootvar command for a Cisco 7513 router configured for high system availability (HSA): Router# show bootvar BOOT variable = CONFIG_FILE variable = Current CONFIG_FILE variable = BOOTLDR variable does not exist Configuration register is 0x0 current slave is in slot 7 BOOT variable = CONFIG_FILE variable = BOOTLDR variable does not exist Configuration register is 0x0 show bootvar CF-602 Cisco IOS Configuration Fundamentals Command Reference April 2010 Table 59 describes the significant fields shown in the displays. Cisco 7600 Series Router This example shows how to display information about the BOOT environment variable: Router# show bootvar BOOT variable = sup-bootflash:c6sup12-js-mz.121-13.E,12 CONFIG_FILE variable = BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-13.E.bin Configuration register is 0x2102 Standby is up Standby has 112640K/18432K bytes of memory.

Command Modes EXEC Command History Usage Guidelines The Cisco link service (CLS) is used as the interface between data link users (DLUs), such as DLSw, LAN Network Manager (LNM), downstream physical unit (DSPU), and SNASw, and their corresponding data link circuits (DLCs) such as Logic Link Control (LLC), VDLC, and Qualified Logic Link Control (QLLC). Each DLU registers a particular service access point (SAP) with CLS, and establishes circuits through CLS over the DLC. The show cls command displays the SAP values associated with the DLU and the circuits established through CLS. For further information about CLS, use the Release 12.2 Cisco IOS Bridging and IBM Networking Configuration Guide. Examples The following is sample output from the show cls command: IBD-4500B# show cls DLU user:SNASW SSap:0x04 VDLC VDLC650 DTE:1234.4000.0001 1234.4000.0002 04 04 T1 timer:0 T2 timer:0 Inact timer:0 max out:0 max in:0 retry count:10 XID retry:10 XID timer:5000 I-Frame:0 flow:0 DataIndQ:0 DataReqQ:0 DLU user:DLSWDLUPEER DLU user:DLSWDLU Bridging VDLC VDLC1000 Bridging VDLC VDLC650 The following is sample output from the show cls brief command: brief (Optional) Displays a brief version of the output.

SNASw uses a SAP value of 0x04, and the associated DLC port is VDLC650. SNASw has a circuit established between MAC addresses 1234.4000.0001 and 1234.4000.0002 using source and destination SAPs 04 and 04. DLSw is a bridging protocol and uses VDLC1000 and VDLC650 ports. There are no circuits in place at this time. In the output from the show cls command (without the brief argument), the values of timers and counters applicable to this circuit are displayed. Related Commands Command Description stun peer-name Enables STUN for an IP address and uses Cisco Link Services (CLS) to access the Frame Relay network. show config id CF-619 Cisco IOS Configuration Fundamentals Command Reference April 2010 show config id The configuration change tracking identifier (CTID) assigns a version number to each saved version of the running-config file. To display output about the versions, use the show config id command in privileged EXEC mode. show config id [detail] Syntax Description Command Default This command is disabled by default. If this command is not entered, the management system has to query the device for the current running-config file and then compare the results to the last known configuration to determine if a change has been made. Command Modes Privileged EXEC (#) Command History Usage Guidelines This configuration infrastructure command assigns a version number that is updated every time the running-config file is changed. This version number is called the configuration change tracking identifier or CTID. The CTID can be used to compare configuration files to track configuration changes and take appropriate actions (for example, a configuration rollback). Config Logger can also use the CTID to determine if there have been any changes to the running-config file. CTID makes the management system more efficient by presenting information that indicates a change has been made to the running-config file. Without CTID, the management system has to query the device for the current running-config file and then compare the results to the last known configuration to determine if a change has been made.

It is documented here in case you need to provide the displayed statistics to an technical support engineer. Cisco 10000 Series Router Usage Guidelines In releases prior to Cisco IOS Release 12.2(33)SB, when you configure the t1 loopback remote command on the local router, the command also displays in the running-config file of the far-end router. This is due to the route processor (RP) updating an incorrect parameter when it receives the loopback event message from the line card for loopback requests from the far end. In Cisco IOS Release 12.2(33)SB, the RP updates the correct parameter and the show controllers command correctly displays the loopback CLI commands applied on the local end and displays the loopback events and status received from the line card in response to loopback requests from the far end. This change in behavior affects the following line cards and is documented in the CSCsm84447 caveat: • 4-port channelized STM1 • 1-port channelized OC-12 • 6-port channelized T3 • 4-port half-height channelized T3 In Cisco IOS Release 12.2(33)SB, the output from the show controller command includes line code information for the 6-port channelized T3 line card and the 8-port E3/DS3 line card. However, because SONET line cards do not have a direct physical link at the T3 or E3 level, the output from the show controller t3 command does not include line code information. In Cisco IOS Release 12.2(31)SB, the output from the show controller command displays line code information. The output of the show controller t3 command for SONET-based T3 also includes line code information. Cisco 12000 Series Router Usage Guidelines The packets processed by a line card are either sent to a route processor or a line card in the form of Cisco cells. To track the packets sent to a route processor from a line card is essential for troubleshooting. The keywords punt-sniff and punt-verbose have been added for the command show controllers events to identify the packets sent to RP from LC. Release Modification 11.2 GS This command was added to support the Cisco 12000 series Gigabit Switch Routers. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. 12.2(31)SB This command was integrated in Cisco IOS Release 12.2(31)SB. 12.2(33)SB This command’ behavior was modified on the Cisco 10000 series router for the PRE3 and PRE4. 12.0(33)S The keywords punt-sniff and punt-verbose were added in the command show controllers events for the Cisco 12000 Series Routers. show controllers (line card image) CF-633 Cisco IOS Configuration Fundamentals Command Reference April 2010 By default, the feature is enabled and packets punt to route processor are displayed using the command show controllers events punt-verbose. To view all the zero and non-zero punt counters use the command show controllers events punt-verbose all. To clear all the line card events and counters including resetting the packets to be sniffed to zero, executing the command show controllers events clear. Packets sent to route processor from line card can be sniffed by specifying the hexa-decimal value of the word. Packets can only be sniffed if the word along with the hexa-decimal value is specified. Specifying the location of the word, sniffs packets from the particular location. To reset the counters of packets to be sniffed to zero, execute the command show controllers events punt-sniff none. For example, use the command show controllers events punt-sniff word1 0x60000000 to sniff packets punt to RP with the hexa-decimal value 0x60000000. As the location is not specified, it searches the entire buffer for the value 0x60000000. Packets punt to RP can also be sniffed by specifying a particular location using the command show controllers events punt-sniff word1 0x60000000 34. Examples Because you are executing this command on the line card, you must use the execute-on command to use the show command, or you must connect to the card using the attach command.

The show derived-config command displays all the commands that apply to an interface. The output for the show derived-config command is nearly identical to that of the show running-config command. It differs when the configuration for an interface is derived from a template, a dialer interface, or some per-user configuration. In those cases, the commands derived from the template, dialer interface, and so on, will be displayed for the affected interface. If the same command is configured differently in two different sources that apply to the same interface, the command coming from the source that has the highest precedence will appear in the display. Examples The following examples show sample output for the show running-config and show derived-config commands for serial interface 0:23 and dialer interface 0. The output of the show running-config and show derived-config commands is the same for dialer interface 0 because none of the commands that apply to that interface are derived from any sources other than the configuration of the dialer interface. The output for the show running-config and show derived-config commands for serial interface 0:23 differs because some of the commands that apply to serial interface 0:23 come from dialer interface 0. Router# show running-config interface Serial0:23 Building configuration...

Command Description diagnostic cns Configures the CNS diagnostics. show diagnostic sanity CF-652 Cisco IOS Configuration Fundamentals Command Reference April 2010 show diagnostic sanity To display sanity check results, use the show diagnostic sanity command in privileged EXEC mode. show diagnostic sanity Syntax Description This command has no arguments or keywords. Defaults Displays information for all the Gigabit Ethernet WAN interfaces in the Cisco 7600 series router. Command Modes Privileged EXEC Command History Usage Guidelines The sanity check runs a set of predetermined checks on the configuration with a possible combination of certain system states to compile a list of warning conditions. The checks are designed to look for anything that seems out of place and are intended to serve as an aid to maintaining the system sanity. The following is a list of the checks that are run and the action taken when the condition is found: • Checks whether the default gateways are reachable. If so, the system stops pinging. • If a port auto-negotiates to half duplex, the system flags it. Trunking Checks • If a trunk port has the mode set to “on,” the system flags it. • If a port is trunking and mode is auto, the system flags it. • If a trunk port is not trunking and the mode is desirable, the system flags it. • If a trunk port negotiates to half duplex, the system flags it. Channeling Checks • If a port has channeling mode set to on, the system flags it. • If a port is not channeling and the mode is set to desirable, the system flags it. • If a VLAN has a Spanning-Tree root of 32K (root is not set), the system flags it. Spanning-Tree VLAN Checks • If a VLAN has a max age on the Spanning-Tree root that is different than the default, the system flags it. • If a VLAN has a fwd delay on the Spanning-Tree root that is different than the default, the system flags it. • If a VLAN has a fwd delay on the bridge that is different than the default, the system flags it. Release Modification 12.2(18)SXE Support for this command was introduced on the Supervisor Engine 720. 12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA. show diagnostic sanity CF-653 Cisco IOS Configuration Fundamentals Command Reference April 2010 • If a VLAN has a fwd delay on the bridge that is different than the default, the system flags it. • If a VLAN has a hello time on the bridge that is different than the default, the system flags it. Spanning-Tree Port Checks • If a port has a port cost that is different than the default, the system flags it. • If a port has a port priority that is different than the default, the system flags it. UDLD Checks • If a port has UDLD disabled, the system flags it. • If a port had UDLD shut down, the system flags it. • If a port had a UDLD undetermined state, the system flags it. Assorted Port Checks • If a port had receive flow control disabled, the system flags it. • If a trunk port had PortFast enabled, the system flags it. • If a inline power port has any of the following states: – denied – faulty – other – off The system flags it. • If a port has a native VLAN mismatch, the system flags it. • If a port has a duplex mismatch, the system flags it. Bootstring and Config Register Checks • The config register on the primary supervisor engine (and on the secondary supervisor engine if present) must be one of the following values: 0x2 , 0x102, or 0x2102. • The system verifies the bootstring on the primary supervisor engine (and on the secondary supervisor engine if present). The system displays a message if the bootstring is empty. • The system verifies that every file is specified in the bootstring. The system displays a message if the file is absent or shows up with a wrong checksum. If only device: is specified as a filename, then the system verifies that the first file is on the device. Assorted Checks • The system displays a message if IGMP snooping is disabled. • The system displays a message if any of the values of the snmp community access strings {RO,RW,RW-ALL} is the same as the default. • The system displays a message if any of the modules are in states other than “Ok.” • The system displays a message that lists all the tests that failed (displayed as an “F”) in the show test all command. • The system displays a message if *fast is not configured on the switch anywhere. • The system displays a message if there is enough room for the crashinfo file on the bootflash:. • The system displays a message if multicast routing is enabled globally but is not applied to all interfaces. show diagnostic sanity CF-654 Cisco IOS Configuration Fundamentals Command Reference April 2010 • The system displays a message if IGMP snooping is disabled and RGMP is enabled.

This is the default. fans (Optional) Displays blower and fan information. hardware (Optional) Displays hardware-specific information. last (Optional) Displays information on the last measurement made. leds (Optional) Displays the status of the MBus LEDs on the clock and scheduler cards and switch fabric cards. power-supply (Optional) Displays power supply voltage and current information. If applicable, displays the status of the redundant power supply. table (Optional) Displays the temperature, voltage, and blower ranges and thresholds. On the Cisco 7200 series, including the NPE-G2 in the Cisco 7200 VXR, the Cisco 7304 routers, and the Cisco 7500 series routers, the table keyword displays only the temperature and voltage thresholds. temperature (Optional) Displays temperature information. voltages (Optional) Displays voltage information. counters Displays operational counters. history Displays sensor state change history. location Displays sensors by location. sensor Displays sensor summary. sensor Sensor name. show environment CF-666 Cisco IOS Configuration Fundamentals Command Reference April 2010 Command Modes User EXEC (>) Privileged EXEC (#) Command History Usage Guidelines The availability of keywords depends on your system and platform. The command does not support SPAs on the Cisco 7200 series and on the NPE-G2 in the Cisco 7200 VXR routers. A routine runs once a minute that reads environmental measurements from sensors and stores the output into a buffer. For shared port adapters (SPAs), the temperature and voltage sensors are read every few seconds to get environmental data. The environmental buffer is displayed on the console when you use the show environment command. If a measurement exceeds desired margins, but has not exceeded fatal margins, a warning message is printed to the system console. The system software queries the sensors for measurements once a minute, but warnings for a given test point are printed at most once every hour for sensor readings in the warning range and once every 5 minutes for sensor readings in the critical range. If a measurement is out of line within these time segments, an automatic warning message appears on the console. As noted, you can query the environmental status with the show environment command at any time to determine whether a measurement is at the warning or critical tolerance. A SPA is shut down when any of the SPA environment readings exceed the shutdown threshold. If a shutdown occurs because of detection of fatal environmental margins, the last measured value from each sensor is stored in internal nonvolatile memory. For environmental specifications, refer to the hardware installation and configuration publication for your individual chassis. For network processor engines (NPEs), network services engines (NSEs), line cards, and modular services cards (MSCs), environmental information is recorded in the CISCO-ENVMON-MIB. SPAs are not supported by the CISCO-ENVMON-MIB. In Cisco IOS Release 12.2(20)S2 and later, the CISCO-ENTITY-SENSOR-MIB supports environmental information for SPAs, as well as NPEs, NSEs, line cards, and MSCs. Release Modification 10.0 This command was introduced. 11.2 GS The alarms, fans, hardware, leds, power-supply, table, temperature, and voltages keywords were added for the Cisco 12000 series GSRs. 11.3(6)AA This command was expanded to monitor the RPS and board temperature for the Cisco AS5300 platform, Cisco 3600 series routers, Cisco 7200 series routers, and the Cisco 12000 series GSRs. 12.2(20)S This command was integrated into Cisco IOS Release 12.2(20)S. 12.2(20)S2 This command was integrated into Cisco IOS Release 12.2(20)S2 to support MSCs and SPAs on the Cisco 7304 router using the all, last, and table keywords. 12.4(4)XD This command was integrated into Cisco IOS Release 12.4(4)XD to support the NPE-G2 on the Cisco 7200 VXR using the all, last, and table keywords. Command output was modified for the NPE-G2. 12.2(31)SB2 This command was integrated into Cisco IOS Release 12.2(31)SB2. Cisco IOS XE Release 2.1 This command was integrated into Cisco IOS XE Release 2.1 on the Cisco ASR 1000 Series Routers. show environment CF-667 Cisco IOS Configuration Fundamentals Command Reference April 2010 If the Cisco 12000 series GSR exceeds environmental conditions, a message similar to the following is displayed on the console: %GSR_ENV-2-WARNING: Slot 3 Hot Sensor Temperature exceeds 40 deg C; Check cooling systems Note Blower temperatures that exceed environmental conditions do not generate a warning message. You can also enable Simple Network Management Protocol (SNMP) notifications (traps or informs) to alert a network management system (NMS) when environmental thresholds are reached using the snmp-server enable traps envmon and snmp-server host global configuration commands. Whenever Cisco IOS software detects a failure or recovery event from the DRPS unit, it sends an SNMP trap to the configured SNMP server. Unlike console messages, only one SNMP trap is sent when the failure event is first detected. Another trap is sent when the recovery is detected. Cisco AS5300 DRPS software reuses the MIB attributes and traps defined in CISCO-ENVMON-MIB and CISCO-ACCESS-ENVMON-MIB. CISCO-ENVMON-MIB is supported by all Cisco routers with RPS units, and CISCO-ACCESS-ENVMON-MIB is supported by the Cisco 3600 series routers. A power supply trap defined in CISCO-ENVMON-MIB is sent when a failure is detected and when a failure recovery occurs for the following events: input voltage fail, DC output voltage fail, thermal fail, and multiple failure events. A fan failure trap defined in CISCO-ENVMON-MIB is sent when a fan failure or recovery event is detected by Cisco IOS software. A temperature trap defined in CISCO-ACCESS-ENVMON-MIB is sent when a board over-temperature condition is detected by Cisco IOS software. CISCO-ACCESS-ENVMON-MIB also defines an over-voltage trap. A similar trap is defined in CISCO-ENVMON-MIB, but it requires the ciscoEnvMonVoltageStatusValue in varbinds. This value indicates the current value of the voltage in the RPS. With Cisco AS5300 RPS units, the current voltage value is not sent to the motherboard. CISCO-ENVMON-MIB is extended to add a new enumerated value, internalRedundant(5), for MIB attribute ciscoEnvMonSupplySource. This is used to identify a RPS unit. Examples Cisco ASR 1000 Series Routers In the following example, the show environment all command displays system temperature, voltage, fan, and power supply conditions.

If the value reaches 44C/111F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state. If the value reaches 59C/138F or greater, you receive a critical (HighCrit) message instead, that indicates the system continues to operate, but the system is approaching shutdown. Note Beware if the temperature reaches or exceeds 80C/176F, which is the HighShut value, a Shutdown message is issued, and the NPE Inlet area shuts down. NPE Outlet 49C/120F 64C/147F These are the HighWarn and HighCrit temperature thresholds, respectively, for the NPE Outlet. If the NPE Outlet temperature value reaches the HighWarn (49C/120F) and HighCrit (64C/147F) levels, warning and critical messages, respectively, are issued. If the value reaches 49C/120F or greater, you receive a warning message indicating HighWarn. The system continues to operate, but operator action is recommended to bring the system back to a normal state. If the value reaches 64C/147F or greater, you receive a critical (HighCrit) message instead that indicates the system continues to operate, but the system is approaching shutdown.

Active fault conditions: Lists any fault conditions that exist (such as power supply failure, fan failure, and temperature too high). Fan transfer point: Software-controlled fan speed. If the router is operating below its automatic restart temperature, the transfer point is reduced by 10 percent of the full range each minute. If the router is at or above its automatic restart temperature, the transfer point is increased in the same way. Active trip points: Compares temperature sensor against the values displayed at the bottom of the show environment table command output. 15 of 15 soft shutdowns remaining When the temperature increases above the “board shutdown” level, a soft shutdown occurs (that is, the cards are shut down, and the power supplies, fans, and CI continue to operate). When the system cools to the restart level, the system restarts. The system counts the number of times this occurs and keeps the up/down cycle from continuing forever. When the counter reaches zero, the system performs a hard shutdown, which requires a power cycle to recover. The soft shutdown counter is reset to its maximum value after the system has been up for 6 hours.
