Green Ethernet
Green Ethernet, also known as Energy Efficient Ethernet (EEE), is an effort
to make networking equipment environmentally friendly, by reducing the
power usage of Ethernet connections.
The Short-Reach method, which reduces power over Ethernet cables shorter
than 40m, is supported by the device.
For more information, see "Green Ethernet Configuration" on page 390.
Head of Line Blocking Prevention
Head of Line (HOL) blocking results in traffic delays and frame loss caused
by traffic competing for the same egress port resources. To prevent HOL
blocking, the device queues packets, and packets at the head of the queue are
forwarded before packets at the end of the queue.
Flow Control Support (IEEE 802.3X)
Flow control enables lower-speed devices to communicate with higher-speed
devices, by requesting that the higher-speed device refrain from sending
packets. Transmissions are temporarily halted to prevent buffer overflows.
For more information, see "Flow Control" on page 386.
Back Pressure Support
On half-duplex links, the receiving port prevents buffer overflows by
occupying the link so that it is unavailable for additional traffic.

Virtual Cable Testing (VCT)
VCTdetects and reports copper link cabling faults, such as open cables and
cable shorts.
For more information, see "Diagnostics" on page 255.
Auto-Negotiation
Auto-negotiation enables the device to advertise modes of operation. The
auto-negotiation function enables an exchange of information between two
devices that share a point-to-point link segment, and automatically
configures both devices to take maximum advantage of their transmission
capabilities.
The PowerConnect 5500 series enhances auto-negotiation by providing port
advertisement. Port advertisement enables the system administrator to
configure the port speeds that are advertised.
For more information, see "Port Configuration" on page 403 or "LAG
Configuration" on page 409.
MDI/MDIX Support
Standard wiring for end stations is known as Media-Dependent Interface
(MDI), and standard wiring for hubs and switches is known as MediaDependent Interface with Crossover (MDIX).
If auto-negotiation is enabled, the device automatically detects whether the
cable connected to an RJ-45 port is MDIX (crossed) or MDI (straight). This
enables both types to be used interchangeably.
If auto-negotiation is not enabled, only MDI (straight) cables can be used.
For more information, see "Port Configuration" on page 403 or "LAG
Configuration" on page 409.
MAC Address Supported Features
MAC Address Capacity Support

Static MAC Entries
MAC entries can be manually entered in the Bridging Table, as an alternative
to learning them from incoming frames. These user-defined entries are not
subject to aging, and are preserved across resets and reboots.
For more information, see "Static Addresses" on page 424.
Self-Learning MAC Addresses
The device enables controlled MAC address learning from incoming packets.
The MAC addresses are stored in the Bridging Table.
For more information, see "Dynamic Addresses" on page 427.
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period, are aged
out. This prevents the Bridging Table from overflowing.
For more information, see "Dynamic Addresses" on page 427.
VLAN-Aware MAC-Based Switching
The device always performs VLAN-aware bridging. Classic bridging
(IEEE802.1D), in which frames are forwarded based only on their destination
MAC address, is not performed. However, a similar functionality can be
configured for untagged frames. Frames addressed to a destination MAC
address that is not associated with any port are flooded to all ports of the
relevant VLAN.
MAC Multicast Support
Multicast service is a limited Broadcast service that enables one-to-many and
many-to-many connections for information distribution. In Layer 2 Multicast
service, a single frame is addressed to a specific Multicast address, from which
copies of the frame are transmitted to the relevant ports. When Multicast
groups are statically enabled, you can set the destination port of registered
groups, as well as define the behavior of unregistered Multicast frames.
For more information, see "Multicast" on page 516.20 Dell PowerConnect 55xx Systems User Guide

Layer 2 Features
IGMP Snooping
Internet Group Membership Protocol (IGMP) Snooping examines IGMP
frame contents, when they are forwarded by the device from work stations to
an upstream Multicast router. From the frame, the device identifies work
stations configured for Multicast sessions, and which Multicast routers are
sending Multicast frames. The IGMP Querier simulates the behavior of a
Multicast router. This enables snooping of the Layer 2 Multicast domain even
if there is no Multicast router.
For more information, see "IGMP Snooping" on page 527.
Port Mirroring
Port mirroring monitors network traffic by forwarding copies of incoming and
outgoing packets from a monitored port to a monitoring port. Users specify
which target port receives copies of all traffic passing through a specified
source port.
For more information, see "Port Mirroring" on page 417.
Broadcast Storm Control
Storm Control enables limiting the number of Multicast and Broadcast
frames accepted by and forwarded by the device.
When Layer 2 frames are forwarded, Broadcast and Multicast frames are
flooded to all ports on the relevant VLAN. This occupies bandwidth, and
loads all nodes connected on all ports.

VLAN Supported Features
VLAN Support
VLANs are collections of switching ports that comprise a single Broadcast
domain. Packets are classified as belonging to a VLAN, based on either the
VLAN tag or on a combination of the ingress port and packet contents.
Packets sharing common attributes can be grouped in the same VLAN.
For more information, see "VLANs" on page 466.
Port-Based Virtual LANs (VLANs)
Port-based VLANs classify incoming packets to VLANs, based on their ingress
port.
For more information, see "Defining VLAN Membership Using CLI
Commands" on page 473.
Full 802.1Q VLAN Tagging Compliance
IEEE 802.1Q defines an architecture for virtual, bridged LANs, the services
provided in VLANs, and the protocols and algorithms involved in the
provision of these services.
For more information, see "Virtual LAN Overview" on page 467.
GVRP Support
GARP VLAN Registration Protocol(GVRP) provides IEEE 802.1Qcompliant VLAN pruning and dynamic VLAN creation. When GVRP is
enabled, the device registers and propagates VLAN membership on all ports
that are part of the active underlying Spanning Tree Protocol topology.
For more information, see "GVRP Parameters" on page 490.
Voice VLAN
Voice VLAN enables network administrators to enhance VoIP service by
configuring ports to carry IP voice traffic from IP phones on a specific VLAN.
VoIP traffic has a preconfigured OUI prefix in the source MAC address.
Network administrators can configure VLANs from which voice IP traffic is 22 Dell PowerConnect 55xx Systems User Guide

forwarded. Non-VoIP traffic is dropped from the Voice VLAN in Auto-Voice
VLAN Secure mode. Voice VLAN also provides QoS to VoIP, ensuring that the
quality of voice does not deteriorate if the IP traffic is received unevenly.
For more information, see "Voice VLAN" on page 498.
Guest VLAN
Guest VLAN provides limited network access to unauthorized ports. If a port
is denied network access via port-based authorization, but the Guest VLAN is
enabled, the port receives limited network access through the Guest VLAN.
For more information, see "Dot1x Authentication" on page 132.
Private VLAN
The Private VLAN feature provides Layer 2 isolation between ports that share
the same Broadcast domain, or in other words, it creates a point-tomultipoint Broadcast domain. The ports can be located anywhere in the
Layer 2 network (compared to the Protected Ports feature, where the ports
must be in the same stack).
For more information, see "Private VLAN" on page 494.
Multicast TV VLAN
The Multicast TV VLAN feature provides the ability to supply multicast
transmissions to Layer 2-isolated subscribers, without replicating the
multicast transmissions for each subscriber VLAN. The subscribers are the
only receivers of the multicast transmissions.
For more information, see "Multicast TV VLAN" on page 535.
Spanning Tree Protocol Features
Spanning Tree Protocol (STP)
802.1d Spanning tree is a standard Layer 2 switch requirement that enables
bridges to automatically prevent and resolve Layer 2 forwarding loops.
Switches exchange configuration messages using specifically-formatted
frames, and selectively enable and disable forwarding on ports.
For more information, see "Spanning Tree" on page 434. Dell PowerConnect 55xx Systems User Guide 23
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGFeatures.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Fast Link
STP can take 30–60 seconds to converge. During this time, STP detects
possible loops, enabling time for status changes to propagate and for relevant
devices to respond. This period of 30-60 seconds is considered too long a
response time for many applications. The Fast Link option bypasses this
delay, and can be used in network topologies, where forwarding loops do not
occur.
For more information on enabling Fast Link for ports and LAGs, see "STP
Port Settings" on page 442 or "Static Addresses" on page 424.
IEEE 802.1w Rapid Spanning Tree
Spanning Tree takes 30–60 seconds for each host to decide whether its ports
are actively forwarding traffic. Rapid Spanning Tree (RSTP) detects uses of
network topologies to enable faster convergence, without creating forwarding
loops.
For more information, see "Spanning Tree" on page 434.
IEEE 802.1s Multiple Spanning Tree
Multiple Spanning Tree (MSTP) operation maps VLANs into STP instances.
MSTP provides a different load balancing scenario. Packets assigned to various
VLANs are transmitted along different paths within MSTP Regions (MST
Regions). Regions are one or more MSTP bridges by which frames can be
transmitted. The standard lets administrators assign VLAN traffic to
unique paths.
For more information, see "Spanning Tree" on page 434.
STP BPDU Guard
BPDU Guard is used as a security mechanism, to protect the network from
invalid configurations.
BPDU Guard is usually used either when fast link ports (ports connected to
clients) are enabled or when the STP feature is disabled. When it is enabled
on a port, the port is shut down if a BPDU message is received and an
appropriate SNMP trap is generated.

Link Aggregation
Up to 32 Aggregated Links may be defined, each with up to eight member
ports, to form a single Link Aggregated Group (LAG). This enables:
• Fault tolerance protection from physical link disruption
• Higher bandwidth connections
• Improved bandwidth granularity
• High bandwidth server connectivity
A LAG is composed of ports with the same speed, set to full-duplex
operation.
For more information, see "LAG Configuration" on page 409.
Link Aggregation and LACP
LACP uses peer exchanges across links to determine, on an ongoing basis, the
aggregation capability of various links, and continuously provides the
maximum level of aggregation capability achievable between a given pair of
devices. LACP automatically determines, configures, binds, and monitors the
port binding within the system.
For more information, see "Link Aggregation" on page 508.
BootP and DHCP Clients
DHCP enables additional setup parameters to be received from a network
server upon system startup. DHCP service is an on-going process. DHCP is an
extension of BootP.

are established or enforced. 802.1p is a spin-off of the 802.1Q (VLANs)
standard. 802.1p establishes eight levels of priority, similar to the IP
Precedence IP Header bit-field.
Advanced QoS
Frames that match an ACL and were permitted entrance are implicitly
labeled with the name of the ACL that permitted their entrance. Advanced
mode QoS actions defined in network policies can then be applied to these
flows.
The switch can set DSCP values and map IPv6 DSCP to egress queues in the
same way it does for IPv4. The switch detects IPv6 frames by the IPv6 ethertype.
For more information about Advanced QoS, see "QoS Advanced Mode" on
page 678.
TCP Congestion Avoidance
The TCP Congestion Avoidance feature activates an algorithm that breaks up
or prevents TCP global synchronization on a congested node, where the
congestion is due to multiple sources sending packets with the same byte
count.
For more information, see "The following is an example of the CLI
commands:" on page 666.
Device Management Features
SNMP Alarms and Trap Logs
The system logs events with severity codes and timestamps. Events are sent as

SNMP Versions 1, 2, and 3
Simple Network Management Protocol (SNMP) over the UDP/IP protocol
controls access to the system. A list of community entries is defined, each
consisting of a community string and its access privileges. There are three
levels of SNMP security: read-only, read-write, and super. Only a super user
can access the Community table.
For more information, see "SNMP" on page 314.
Web-Based Management
Web-based management enables managing the system from any web browser.
The system contains an Embedded Web Server (EWS) that serves HTML
pages, through which the system can be monitored and configured. The
system internally converts web-based input into configuration commands,
MIB variable settings, and other management-related settings.
Management IP Address Conflict Notification
This feature validates the uniqueness of the switch's IP address, whether it is
assigned manually or through DHCP. If the IP address is not unique, the
switch performs actions according to the address type. If the IP address is
static, see more information about this in "IPv4 Interface Parameters" on
page 210. If the IP address is dynamic, see more information about this
in"DHCP IPv4 Interface" on page 214.
Flow Monitoring (sflow)
The switch supports statistics collection, using a sampling technology called
sFlow that is based on RFC 3176. The sFlow sampling technology is
embedded within the switch, and provides the ability to continuously
monitor traffic flows on some or all the interfaces simultaneously.
For more information, see "sFlow" on page 375.
Configuration File Download and Upload
The device configuration is stored in a configuration file. The configuration
file includes both system-wide and port-specific device configuration. The

upload/download via TFTP.
USB File Transfer Protocol
The device supports boot image, software, and configuration
upload/download via USB.
Remote Monitoring
Remote Monitoring (RMON) is an extension to SNMP that provides
comprehensive network traffic monitoring capabilities. RMON is a standard
MIB that defines MAC-layer statistics and control objects, enabling real-time
information to be captured across the entire network.
For more information, see "Statistics/RMON" on page 606.
Command Line Interface
Command Line Interface (CLI) syntax and semantics conform as much as
possible to common, industry standards. CLI is composed of mandatory and
optional elements. The CLI interpreter provides command and keyword
completion to assist users and save typing.
Syslog
Syslog is a protocol that enables event notifications to be sent to a set of
remote servers, where they can be stored, examined, and acted upon. The
system sends notifications of significant events in real time, and keeps a
record of these events for after-the-fact usage.

SNTP
The Simple Network Time Protocol (SNTP) assures accurate network
Ethernet Switch clock time synchronization up to the millisecond. Time
synchronization is performed by a network SNTP server. Time sources are
prioritized by strata. Strata define the distance from the reference clock. The
higher the stratum (where zero is the highest), the more accurate the clock.
For more information, see "Time Synchronization" on page 169.
Domain Name System
Domain Name System (DNS) converts user-defined domain names into IP
addresses. Each time a domain name is assigned, the DNS service translates
the name into a numeric IP address. For example, www.ipexample.com is
translated into 192.87.56.2. DNS servers maintain domain name databases
containing their corresponding IP addresses.
For more information, see "Domain Name System" on page 242.
802.1ab (LLDP-MED)
The Link Layer Discovery Protocol (LLDP) enables network managers to
troubleshoot, and enhances network management by discovering and
maintaining network topologies over multi-vendor environments. LLDP
discovers network neighbors by standardizing methods for network devices to
advertise themselves to other systems, and to store discovered information.
The multiple advertisement sets are sent in the packet Type Length Value
(TLV) field. LLDP devices must support chassis and port ID advertisement,
as well as system name, system ID, system description, and system capability
advertisements.
LLDP Media Endpoint Discovery (LLDP-MED) increases network flexibility
by enabling various IP systems to co-exist on a single network LLDP. It
provides detailed network topology information, emergency call service via IP
phone location information, and troubleshooting information.

Security Features
SSL
Secure Socket Layer (SSL) is an application-level protocol that enables secure
transactions of data through privacy, authentication, and data integrity. It
relies upon certificates and public and private keys.
Port-Based Authentication (Dot1x)
Port-based authentication enables authenticating system users on a per-port
basis via an external server. Only authenticated and approved system users
can transmit and receive data. Ports are authenticated via the Remote
Authentication Dial-In User Service (RADIUS) server using the Extensible
Authentication Protocol (EAP). Dynamic VLAN Assignment (DVA) enables
network administrators to automatically assign users to VLANs during the
RADIUS server authentication.
For more information, see "Dot1x Authentication" on page 132.
Locked Port Support
Locked Port increases network security by limiting access on a specific port to
users with specific MAC addresses. These addresses are either manually
defined or learned on that port. When a frame is seen on a locked port, and
the frame source MAC address is not tied to that port, the protection
mechanism is invoked.
For more information, see "Port Security" on page 98.
RADIUS Client
RADIUS is a client/server-based protocol. A RADIUS server maintains a user
database that contains per-user authentication information, such as user
name, password, and accounting information.
RADIUS Accounting
This feature enables recording device management sessions (Telnet, serial,
and WEB but not SNMP) and/or 802.1x authentication sessions.30 Dell PowerConnect 55xx Systems User Guide

Due to the complexity of 802.1x setup and configuration, many mistakes can
be made that might cause loss of connectivity or incorrect behavior. The
802.1x Monitor mode enables applying 802.1x functionality to the switch,
with all necessary RADIUS and/or domain servers active, without actually
taking any action that may cause unexpected behavior. In this way, the user
can test the 802.1x setup before actually applying it.
For more information, see "RADIUS" on page 291.
SSH
Secure Shell (SSH) is a protocol that provides a secure, remote connection to
a device. SSH version 2 is currently supported. The SSH server feature
enables an SSH client to establish a secure, encrypted connection with a
device. This connection provides functionality that is similar to an inbound
telnet connection. SSH uses RSA and DSA Public Key cryptography for
device connections and authentication.
For more information, see "Security Management and Password
Configuration" on page 75.
TACACS+
TACACS+ provides centralized security for validation of users accessing the
device. TACACS+ provides a centralized, user management system, while
still retaining consistency with RADIUS and other authentication processes.
For more information, see "TACACS+" on page 282.
Password Management
Password management provides increased network security and improved
password control. Passwords for SSH, Telnet, HTTP, HTTPS, and SNMP
access are assigned security features.

Dynamic ACL/Dynamic Policy Assignment (DACL/DPA)
The network administrator can specify the user's ACL in the RADIUS server.
After successful authentication, the user is assigned that ACL.
For more information, see "Network Security" on page 97.
DHCP Snooping
DHCP Snooping expands network security by providing firewall security
between untrusted interfaces and DHCP servers. By enabling DHCP
Snooping, network administrators can differentiate between trusted
interfaces connected to end-users or DHCP servers and untrusted interfaces
located beyond the network firewall.
For more information, see "DHCP Snooping" on page 573.
ARP Inspection
Dynamic ARP inspection is a security feature that validates ARP packets in a
network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC
address bindings. This capability protects the network from certain man-inthe-middle attacks.
Port Profile (CLI Macro)
Macros provide a convenient way to save and share a common configuration.
A macro is a set of CLI commands with a unique name. When a macro is

Stacking Overview
This section describes how the Stacking feature of the PowerConnect 5500
series functions.
It contains the following topics:
• Stack Overview
• Stack Members and Unit IDs46 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGStacking.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Stack Overview
The PowerConnect 5500 Stacking feature provides multiple switch
management through a single switch, so that all units in the stack are treated
as if they were a single switch. All stack members are accessed through the
management IP address, through which the stack is managed.
Each switch is a member in a stack, although the stack may consist of only a
single switch.
Up to eight units can be stacked.
This section covers the following topics:
• Stack Operation Modes
• Stacking Units
• Stack Topology
Stack Operation Modes
All stacks must have a Master unit, and may have a Master Backup unit. All
other units are connected to the stack as members (slaves).
A unit in the stack can be in one of the following modes:
• Stack Master — Runs the fully operational software of a switch. In
addition, it runs configures and manages all other units in the stack. All
protocols run in the context of the Master unit. It is responsible for
updating and synchronizing the Master Backup.
The Stack Master detects and reconfigures the ports with minimal
operational impact in the event of:
Unit failure
Inter-unit stacking link failure
Unit insertion
Unit removal
When the Master unit boots, or when inserting or removing a stack
member, the Master unit initiates a stacking discovering process. Dell PowerConnect 55xx Systems User Guide 47
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGStacking.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Slave Unit — Runs a slave version of the software that enables the
applications running on the Master’s CPU to control and manage the
resources of the slave unit.
• Master Backup — Runs as a slave unit, as described above, and in
addition, continuously monitors the existence and operation of the stack
master. If the master unit fails, the master-backup unit assumes the Master
Backup role.
Stacking Units
PowerConnect 5500 series switches use two HDMI 10G ports for stacking.
To connect the units in the stack:
1 Insert one end of an HDMI cable into the left-hand HDMI port on the
unit at the top of the stack and the other end into the right-hand HDMI
port of the unit immediately below it (this is called crossover).
2 Repeat this process until all units are connected.
3 (Optional) Connect the left-hand HDMI port of the unit at the bottom of
the stack to the right-hand HDMI port of the unit at the top of the stack.
This step provides increased bandwidth and redundancy.48 Dell PowerConnect 55xx Systems User Guide

Stack Topology
The PowerConnect 5500 series systems operates in a ring or chain topology.
Ring Topology
In a ring topology all units in the stack are connected to each other, forming a
circle. Each unit in the stack accepts data and sends it to the unit to which it
is attached. The packet continues through the stack until it reaches its
destination. The system discovers the optimal path on which to send traffic.
Figure 4-1 shows units of a stack connected in a ring topology.
Stacking Failover Topology - Chain Topology
Difficulties occur when a unit in the ring becomes non-functional, or a link is
severed. In this case, the system automatically switches to a chain topology,
without any system downtime.
In chain topology, each unit in the stack is connected to neighboring unit
except for the last unit, which is not connected to any other unit.
In the chain topology, the stack continues to function as long as there is a
master- or backup-enabled unit in each segment of the stack.
When the ring topology is switched to chain topology, an SNMP message is
automatically generated, but no stack management action is required. The
unit that failed must be repaired to restore full stacking operation in the ring
topology.
After the stacking issues are resolved, the units can be reconnected without
interruption, and the ring topology is restored.
Stack Members and Unit IDs
This section describes how to configure the stack.
It contains the following topics:
• Adding a Unit to the Stack
• Assigning Unit IDs
• Selecting the Master and Master Backup Units
• Switching from the Master to the Master Backup
• Replacing Stacking Members50 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Loading Software onto Stack Members
• Rebooting the Stack
• Managing Configuration Files on the Stack
Adding a Unit to the Stack
The recommended procedure to add a unit to a stack is as follows:
1 Place the powered-off unit in its physical place in the stack, and insert the
stacking link in the unit (but do not connect it to the rest of the stack).
2 Power up the unit, and set the correct Unit ID, as described below.
3 Reboot the unit and connect it to the rest of the stack through the stack
link.
Assigning Unit IDs
Each unit in the stack has a unique ID that defines the unit’s position and
function in the stack, as shown in Figure 3-2.
The unit that is assigned Unit ID 1 is the Master unit, by default. The unit
that is assigned Unit ID 2 is the Master Backup unit.
When you power-up the stack, each unit is assigned a unique Unit ID. This is
displayed on the front panel of the unit, as shown in Figure 3-2.
The Unit ID of each unit can be either automatically assigned or manually
assigned, as described in step 1 to step 4 below.
To assign IDs to the units in the stack, do the following for each unit in the
stack:
1 Connect the unit to the terminal.Dell PowerConnect 55xx Systems User Guide 51
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGStacking.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
2 Turn on the unit to begin auto boot and press Return or Esc to abort and
enter the Start Up menu.
3 Select Stack Menu to open the Stack Menu.
4 Select Set Unit Stack ID. Enter either a Unit ID for manual assignment or
0 to indicate that the unit ID will be assigned automatically.
NOTE: The entire stack should be connected, as shown in Figure 4-1, before
powering up the units.
Selecting the Master and Master Backup Units
A unit is master-enabled if it assigned Unit ID 1 and Unit 2. All other units in
the stack (slaves) have unit IDs of 3-8.
The stack master assignment is performed during the configuration boot
process. One master-enabled stack member is elected as Master, and the
other master-enabled stack member is selected as Master Backup, according
to the following decision process:
• A master is selected from the set of the two Master-enabled units. Priority
is given to the lowest unit ID, but also takes into account the amount of
time the unit is UP (Up Time) as follows:

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
– When a master-enabled unit is inserted to a running stack, (or when
Master and Backup master both start at the same time), they
exchange each other’s UP TIME (the time since they powered up). If
the time difference is smaller than 10 minutes, the unit with the
lowest unit ID is elected; otherwise, the unit with the longest UP time
is elected.
– If a Master-enabled unit (with ID 1 or 2) is inserted into an
operational stack, it will be elected as a backup master.
– If a Master unit and/or a backup Master unit is removed from the
stack and the user wishes to configure one of the slave units
(numbered 3-8) to be a Master backup, the user must reset the unit’s
ID. This can be done as follows:
• If there is a Master-enabled unit in the stack: Do -switch n
renumber 2 (through CLI or GUI). This makes the nth unit a
master-enabled unit.
• If there is no Master-enabled unit in the stack: Press the reset
button on the unit to be master-enabled, and assign it a unit ID=
1 using the boot menu.
• The user can force a master-enabled unit to be the master unit of the
stack, even if the master election process did not select it. This is done by
switching over to the backup unit.
NOTE: Two stacking member are considered the same age if they were
inserted within a ten minute interval, for example, if Unit 2 is inserted in the
first minute of a ten-minute cycle, and Unit 1 is inserted in fifth minute of the
same cycle, the units are considered to be the same age.
NOTE: If two stack members are discovered to have the same Unit ID, only
the older unit is included in the stack. The stack continues to function and a
message is sent notifying that a unit failed to join the stack.
The Stack Master and the Master Backup maintain a Warm Standby. The
Warm Standby ensures that the Master Backup takes over for the Stack
Master if a failover occurs, so that the stack continues to operate normally.
During the Warm Standby, the Master and the Master Backup are
synchronized with the static configuration. When the Stacking Master is
configured, it must synchronize the Master Backup. The dynamic Dell PowerConnect 55xx Systems User Guide 53

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
configuration is not saved, for example, dynamically-learned MAC addresses
are not saved, but dynamic information is learned quickly and automatically
by network traffic.
Switching from the Master to the Master Backup
The Master Backup replaces the Stack Master if one or more of the following
events occur:
• The Stack Master fails or is removed from the stack.
• Links from the Stack Master to the stacking members fails.
• User performs soft switchover via the Web interface or the CLI.
Switching between the Stack Master and the Master Backup results in limited
service loss. Dynamic tables are relearned if a failure occurs. The Running
Configuration file is synchronized between Stack Master and the Master
Backup, and continues running on the Master Backup.
Replacing Stacking Members
If a unit is removed from the stack, and replaced with a unit with the same
unit ID, the stack member is configured with the original unit configuration.
Otherwise, if the new unit has either more or fewer ports than the previous
unit, the results depend on the device type of the new and original units, as
defined in Table 4-1:
Table 4-1. Port Configurations when Replacing Units

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Loading Software onto Stack Members
Software can be downloaded to all units simultaneously, or to the master unit
alone. If software is only loaded to the master unit, when new software is
selected, and the Master is rebooted, the Master updates the software on the
remaining units.
In this way, all units in the stack run the same software version.
Rebooting the Stack
Whenever a reboot occurs, topology discovery is performed, and the Master
learns all units IDs in the stack.
Configuration files are changed only through explicit user configuration, and
are not automatically modified when units are added, removed or reassigned
unit IDs.
Each time the system reboots, the Startup Configuration file in the Master
unit is used to configure the stack.
Managing Configuration Files on the Stack
The Startup Configuration and Running Configuration file are stored on the
stack master.
Each port in the stack is referenced in the configuration files by its port type
and unit ID/0/port number, for example "gi1/0/24", which means Giga port 24
on unit 1 (the middle 0 is reserved for future use).
Configuration files are managed from the Stack Master, including:
• Saving to flash memory

Connecting the Switch to the Terminal
The switch is configured and monitored through a terminal desktop system
that runs terminal emulation software. The switch connects to the terminal
through the console port.
To connect the switch to a terminal:
1 Connect an RS-232 cable to a VT100-compatible terminal or the serial
connector of a desktop system running terminal emulation software.
2 Connect the RS-232 cable to the switch console port on the front panel of
the switch (see Figure 5-1) using an 8-pin RJ-45 male connector.

Booting the Switch
After the local terminal is connected, turn on power. The switch then goes
through power-on self-test (POST). POST runs every time the switch is
started and checks hardware components, to determine if the switch is
operational before completely booting. If the system detects a critical
problem, the boot process stops. If POST passes successfully, a valid
executable image is loaded into RAM. POST messages are displayed on the
terminal and indicate test success or failure.
The boot process runs for approximately 40-45seconds.
When the boot process completes, the following LEDs are lit, as shown in
Figure 5-2:

Configuring the Stack
The switch is always considered to be a stack of switches even if the stack only
contains a single switch. If there is more than one switch in the stack, each
switch must be configured individually. See "Assigning Unit IDs" on page 50
for instructions on how to configure the stack.
Configuration Using the Setup Wizard
The Setup Wizard guides you through the initial switch configuration to get
the system up and running as quickly as possible. Note that you can skip the
Setup Wizard and configure the switch manually through the CLI.
The Setup Wizard configures the following fields:
• SNMP Community String and SNMP Management System IP address
(optional)
• Username and password
• Management switch IP address
• IP subnet mask
• Default gateway IP address
NOTE: The Setup Wizard assumes the following:
• The PowerConnect switch was never configured before and is in the same
state as when you received it.
• The PowerConnect switch booted successfully.
• The console connection is established and the console prompt is displayed on
the screen of a VT100 terminal switch.
Connect the Master unit to a terminal. You can identify the Master unit by
the illuminated Master LED on the front panel of the switch (see Figure 3-2).
To configure the system using the Setup Wizard:

Using the CLI
This section provides some general information for using the CLI.
For a complete description of CLI commands, refer to the Dell
PowerConnect 55xx Systems CLI Reference Guide.
Command Mode Overview
The CLI is divided into command modes, each with a specific command set.
Entering a question mark at the terminal prompt displays a list of commands
available for that particular command mode.
In each mode, a specific command is used to navigate from one mode to
another.
These modes are described below.
User EXEC Mode
During CLI session initialization, the CLI is in User EXEC mode. Only a
limited subset of commands is available in User EXEC mode. This level is
reserved for tasks that do not change the terminal configuration and is used
to access configuration sub-systems.
After logging into the device, User EXEC command mode is enabled. The
user-level prompt consists of the host name followed by the angle bracket
(>). For example: console>
NOTE: The default host name is console unless it has been modified during
initial configuration.
The User EXEC commands enable connecting to remote devices, changing
terminal settings on a temporary basis, performing basic tests, and listing
system information.
To list the User EXEC commands, enter a question mark at the command
prompt.
To enter the next level, Privileged EXEC mode, a password is required (if
configured).
Privileged EXEC Mode
Privileged EXEC mode provides access to the device global configuration. Dell PowerConnect 55xx Systems User Guide 69
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGAdvanced Configuration.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Privileged access can be protected, to prevent unauthorized access and to
secure operating parameters. Passwords are displayed on the screen, and are
case-sensitive.
NOTE: The enable command is only necessary if you login with privilege level less
than 15.
To access and list the Privileged EXEC mode commands:
1 At the prompt type enable and press .
2 When a password prompt displays, enter the password and press
.
The Privileged EXEC mode prompt displays as the device host name
followed by #. For example: console#
To list the Privileged EXEC commands, type a question mark at the
command prompt.
To return from Privileged EXEC mode to User EXEC mode, type disable
and press .
The following example illustrates accessing privileged EXEC mode and then
returning to the User EXEC mode:
Use the exit command to return to a previous mode.
To configure the device, enter the next level, Global Configuration mode.
Global Configuration Mode
The Global Configuration mode manages device configuration on a global
level. Global Configuration commands apply to system features, rather than a
specific protocol or interface.

To access Global Configuration mode, at the Privileged EXEC Mode prompt,
type configure and press . The Global Configuration mode displays
as the device host name followed by (config) and the pound sign #.
To list the Global Configuration commands, enter a question mark at the
command prompt.
The following example illustrates how to access Global Configuration mode
and return back to the Privileged EXEC mode:
Interface Configuration Mode
The Interface Configuration mode configures the device at the physical
interface level (port, VLAN, or LAG). Interface commands that require
subcommands have another level, called the Subinterface Configuration
mode. A password is not required to access this level.
The following example, places the CLI in Interface Configuration mode on
port 1/0/1. The sntp command is then applied to that port.
To run a command in a mode, which does not contain it, use do before the
command, as in the following example:
console# configure
console(configure)#
console#
console# configure
console(config)# exit
console#
console# configure
console(config)# interface gi1/0/1

Accessing the Device Through the CLI
You can manage the device using CLI commands, over a direct connection to
the terminal console, or via a Telnet connection.
Direct Connection
Connect the device to the console and enter the CLI commands upon
receiving a prompt.
Telnet Connection
Telnet is a terminal emulation TCP/IP protocol. RS-232 terminals can be
virtually connected to the local device through a TCP/IP protocol network.
Telnet is an alternative to a local login terminal, where a remote login is
required.
The device supports up to four simultaneous Telnet sessions. All CLI
commands can be used over a Telnet session.
If access is via a Telnet connection, ensure that the device has an IP address
and that software has been downloaded to the device.
To start a Telnet session:
1 Select Start > Run.
The Run window opens.
2 Type cmd.
The cmd window opens.
3 In the cmd window, type Telnet .
The Telnet session begins.72 Dell PowerConnect 55xx Systems User Guide

Retrieving an IP Address
Receiving an IP Address from a DHCP Server
When using the DHCP protocol to retrieve an IP address, the device acts as a
DHCP client. When the device is reset, the DHCP command is saved in the
configuration file, but the IP address is not.
To retrieve an IP address from a DHCP server, perform the following steps:
1 Select and connect any port to a DHCP server or to a subnet that has a
DHCP server on it.
2 Type the following commands to use the selected port for receiving the IP
address.
a Assigning dynamic IP Addresses on a port:
b Assigning a dynamic IP Addresses on a VLAN:
The interface receives the IP address automatically.

FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGAdvanced Configuration.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
3 To verify the IP address, type show ip interface at the system prompt, as
shown in the following example.
When configuring/receiving IP addresses through DHCP and BOOTP (an
older version of DHCP), the configuration received from these servers
includes the IP address and may include the subnet mask and default
gateway.
NOTE: It is not necessary to delete the device configuration to retrieve an IP
address from the DHCP server.
NOTE: When copying configuration files, avoid using a configuration file that
contains an instruction to enable DHCP on an interface that connects to the same
DHCP server, or to one with an identical configuration. In this instance, the device
retrieves the new configuration file and boots from it. The device then enables
DHCP, as instructed in the new configuration file, and the DHCP instructs it to reload
the same file.
NOTE: If you configure a DHCP IP address, this address is dynamically retrieved,
and the ip address dhcp command is saved in the configuration file. In the event of
master failure, the backup will again attempt to retrieve a DHCP address. This could
result in one of the following:
• The same IP address may be assigned.
• A different IP address may be assigned, which could result in loss of
connectivity to the management station.
• The DHCP server may be down, which would result in IP address retrieval
failure, and possible loss of connectivity to the management station.
Receiving an IP Address From a BOOTP Server
The standard BOOTP protocol is supported and enables the device to
automatically download its IP host configuration from any standard BOOTP
server in the network. In this case, the device acts as a BOOTP client.

To retrieve an IP address from a BOOTP server:
1 Select and connect any port to a BOOTP server or subnet containing such
a server.
2 At the system prompt, enter the delete startup configuration command to
delete the Startup Configuration from flash.
The device reboots with no configuration and in 60 seconds starts sending
BOOTP requests. The device receives the IP address automatically.
NOTE: When the device reboot begins, any input at the ASCII terminal or keyboard
automatically cancels the BOOTP process before completion and the device does
not receive an IP address from the BOOTP server.
The following example illustrates the process:
To display the IP address, enter the show ip interface command.
The device is now configured with an IP address.

Security Management and Password
Configuration
System security is handled through the Authentication, Authorization, and
Accounting (AAA) mechanism that manages user access rights, privileges,
and management methods. AAA uses both local and remote user databases.
Data encryption is handled through the SSH mechanism.
Passwords can be configured for the following services:
• Terminal
• Telnet
• SSH
• HTTP
• HTTPS
NOTE: When creating a user name, the default priority is 1, which provides access
but not configuration rights. A priority of 15 must be set to enable access and
configuration rights to the device. Although user names can be assigned privilege
level 15 without a password, it is recommended to always assign a password. If
there is no specified password, privileged users can access the Web interface with
any password.
NOTE: Passwords can be secured by using password management commands to
force aging out of passwords, or expiration of passwords. For more information, see
"Management Security" on page 261.
Initial Configuration and Password Recovery
The system is delivered without a default password, and all passwords must be
defined by the user. If a user-defined password is lost, a password recovery
procedure can be invoked from the Startup menu. This procedure is
applicable for the local terminal only and enables a single access to the device
from the local terminal with no password entered.
The full mode of password recovery mechanism can be enabled/disabled
through the CLI (service password-recovery command).
This affects password recovery in the following way:
• Enabled: When the password-recovery mechanism is invoked, one-time
access to the device without a password is enabled and all configuration
and user files are retained.76 Dell PowerConnect 55xx Systems User Guide

Software Download
This section contains instructions for downloading device software (system
and boot images) through a TFTP server or USB port. The TFTP server must
be configured before downloading the software.
Software Auto Synch in Stack
When several units are stacked, they must all run the same software version.
When a new slave device is inserted into the stack, it is first checked for
compatibility (meaning that the master can run firmware upgrade/downgrade
to the slave unit), and if found compatible, its boot and image software
versions are automatically updated with the Master’s. If the slave is found not
compatible, it is shutdown.
A SYSLOG message is sent when a master synchronizes a slave's software.
System Image Download
When the device boots, it decompresses the system image from the flash
memory area and runs it. When a new image is downloaded, it is saved in the
other area allocated for the other system image copy.
On the next boot, the device decompresses and runs the image from the
currently active system image.
A system image can be downloaded through a USB port or a TFTP server.
To download the system image from a TFTP server, ensure that an IP address
is configured on one of the device ports and pings can be sent to the TFTP
server. In addition, ensure that the file to be downloaded is saved on the
TFTP server.
To download a system image through the USB port or TFTP server:
1 Enter the show version command, to verify which software version is
currently running on the device. The following is an example of the

Port Security
Network security can be enhanced by limiting access on a port to users with
specific MAC addresses. The MAC addresses can be dynamically learned, or
they can be statically configured.
Port security has the following modes:
• Classic Lock — Locked port security monitors both received and learned
packets that are received on specific ports. Access to the locked port is
limited to users with specific MAC addresses. These addresses are either
manually defined on the port, or learned on that port before it was locked.
• Limited Dynamic Lock — When a packet is received on a locked port,
and the packet’s source MAC address is not tied to that port (either it was
learned on a different port, or it is unknown to the system), a protection
mechanism, which provides various options is invoked. Unauthorized
packets arriving to a locked port are either:
– Forwarded
– Discarded with no trap
– Discarded with a trap
– The port is shutdown
Locked port security enables storing a list of MAC addresses in the
configuration file. The MAC addresses are restored when the device is reset.
Disabled ports can be activated from the Port Configuration page. Dell PowerConnect 55xx Systems User Guide 99

• Limited Dynamic Lock — Locks the port by deleting the
dynamic MAC addresses associated with the port. The port learns
up to the maximum addresses allowed on the port. Both
relearning and aging MAC addresses are enabled.
– Max Entries (0-128) — Enter the maximum number of MAC
addresses that can be learned on the port. The Max Entries field is
enabled only if Locked is selected in the Set Port field, and the
Limited Dynamic Lock mode is selected in Learning Mode field.
– Action on Violation — Select the action to be applied to packets
arriving on a locked port. The possible options are:
• Discard — Discard the packets from any unlearned source.
• Forward — Forward the packets from an unknown source,
without learning the MAC address.
• Shutdown — Discard the packet from any unlearned source, and
shut down the port. Ports remain shutdown until they are
reactivated, or the device is reset.

ACLs
This section describes Access Control Lists (ACLs), which enable defining
classification actions and rules for specific ingress or egress ports.
It contains the following topics:
• ACL Overview
• MAC-Based ACLs
• MAC-Based ACEs
• IPv4-Based ACLs
• IPv4-Based ACEs
• IPv6-Based ACLs
• IPv6-Based ACEs
ACL Overview
Access Control Lists (ACLs) enable network managers to define classification
actions and rules for specific ingress or egress ports. Packets entering an
ingress or egress port, with an active ACL, are either admitted or denied entry.
If entry is denied, the ingress or egress port may be disabled, for example, a
network administrator defines an ACL rule that states that port number 20
can receive TCP packets, however, if a UDP packet is received, the packet is
dropped.
ACLs are composed of Access Control Entries (ACEs) that are rules that
determine traffic classifications. Each ACE is a single rule, and up to 256
rules may be defined on each ACL, and up to 3000 rules globally.
Rules are not only used for user configuration purposes, they are also used for
features like DHCP Snooping, Protocol Group VLAN and iSCSI, so that not
all 3000 rules are available for ACEs. It is expected that there will be at least
2000 rules available. If there are fewer rules available, this may be due to
DHCP Snooping or iSCSI optimization. Reduce the number of entries in
DHCP Snooping or reduce the max number of TCP connections in the iSCSI
configuration in order to free rules for ACEs.
The following types of ACLs can be defined:
• MAC-based ACL — Examines Layer 2 fields only
• IPv4-based ACL —Examines the Layer 3 layer of IPv4 frames104 Dell PowerConnect 55xx Systems User Guide

ACL Binding
When an ACL is bound to an interface, all the rules that have been defined
for the ACL are applied to that interface. Whenever an ACL is assigned on a
port or LAG, flows from that ingress or egress interface that do not match the
ACL, are matched to the default rule, which is to Drop unmatched packets.
To change the default action for unmatched packets to an action other than
Drop, do the following:
• Add an additional ACE to the ACL with "Any" in all fields
• Set its action other than Drop
• Set the priority to the lowest in the ACL.
To bind ACLs to interfaces:

Time Range
Time ranges can be defined and associated with an QoS ACL, so that it is
applied only during that time range.
There are two types of time ranges:
• Absolute —This type of time range begins on a specific date or
immediately and ends on a specific date or extends infinitely. It is created
in the Time Range pages. A recurring element can be added to it.
• Recurring — This is a time range element that is added to an absolute
range, and begins and ends on a recurring basis. It is defined in the Time
Range Recurrence pages.
If a time range includes both absolute and recurring ranges, the ACL is
activated only if both absolute start time and the recurring time range have
been reached. The ACL is deactivated when either of the time ranges is
reached.
The switch supports a maximum of 10 absolute time ranges.
All time specifications are interpreted as local time (Daylight Savings Time
does not affect this).
To ensure that the time range entries take effect at the desired times, the
system time must be set. For more information on setting the system time,
see "Time Synchronization" on page 169.
A possible use for this feature is to limit access of computers to the network
only during business hours, after which they are locked, and access to the rest
of the network is blocked.128 Dell PowerConnect 55xx Systems User Guide

Port-Based Authentication Overview
Port-based authentication enables authenticating system users on a per-port
basis via an external server. Only authenticated and approved system users
can transmit and receive data. Ports are authenticated via the RADIUS server
using the Extensible Authentication Protocol (EAP). Port Authentication
includes:
• Authenticators — Specifies the device port that is authenticated before
permitting system access.
• Supplicants — Specifies the host connected to the authenticated port hat
is requesting to access the system services.
• Authentication Server — Specifies the external server, for example, a
RADIUS server, which performs authentication on behalf of the
authenticator, and indicates whether the supplicant is authorized to access
system services.
Port-based authentication creates two access states:
• Controlled Access — Permits communication between the supplicant and
the system, if the supplicant is authorized.
• Uncontrolled Access — Permits uncontrolled communication, regardless
of the port authorization state.Dell PowerConnect 55xx Systems User Guide 133

The device supports Port Based Authentication via RADIUS servers.
Dot1x Overview
Dot1x is an IEEE standard for port-based network access control. The Dot1x
framework enables a device (the supplicant) to request port access from a
remote device (authenticator) to which it is connected. The supplicant is
permitted to send data to the port only after it is authenticated and
authorized. If it is not authenticated and authorized, the authenticator
discards the supplicant data, unless the data is sent to a Guest VLAN and/or
non-authenticated VLANs.
Authentication of the supplicant is performed by an external RADIUS server
through the authenticator. The authenticator monitors the results of the
authentication.
In the Dot1x standard, a device can be a supplicant and an authenticator at a
port, simultaneously requesting and granting port access. However, this
device can only act as an authenticator, and does not take on the role of a
supplicant.
The following varieties of Dot1x exist:
• Single session Dot1x:
– A1—Single-session/Single Host — In this mode, the switch, as an
authenticator, supports a single Dot1x session, and grants permission
to use the port to an authorized supplicant. All other access requests,
made by other devices received from the same port, are denied until
the authorized supplicant is no longer using the port, or the access
request is to an unauthenticated or guest VLAN.
– Single-session/Multiple Hosts—This follows the Dot1x standard. In
this mode, the switch, as an authenticator, enables any device to use a
port, as long as it has been granted permission as a supplicant at the
port.
• Multi-Session Dot1x—Every device (supplicant) connecting to a port
must be authenticated and authorized by the switch (authenticator),
separately in a different Dot1x session. This is the only mode that supports
Dynamic VLAN Assignment (DVA).134 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Dynamic VLAN Assignment (DVA)
Dynamic VLAN Assignment (DVA) is also referred to as RADIUS VLAN
Assignment in this guide. When a port is in Multiple Session mode and is
DVA-enabled, the switch automatically adds the port as an untagged member
of the VLAN that is assigned by the RADIUS server during the authentication
process. The switch classifies untagged packets to the assigned VLAN if the
packets originated from the devices or ports that are authenticated and
authorized.
For a device to be authenticated and authorized at a DVA-enabled port:
• The RADIUS server must authenticate the device and dynamically assign
a VLAN to the device.
• The assigned VLAN must not be the default VLAN and must have been
created on the switch.
• The switch must not be configured to use both a DVA and a MAC-based
VLAN group.
• A RADIUS server must support DVA with RADIUS attributes tunnel-type
(64) = VLAN (13), tunnel-media-type (65) = 802 (6), and tunnel-privategroup-id = a VLAN ID.
Dynamic Policy/ACL Assignment
The Dynamic Policy/ACL Assignment feature enables specifying a userdefined ACL or policy in the RADIUS server. After a successful
authentication, the user is assigned that ACL.
Authentication Methods
The possible authentication methods are:
• Dot1x — The switch supports this authentication mechanism, as
described in the standard, to authenticate and authorize Dot1x
supplicants.
• MAC-based — The switch can be configured to use this method to
authenticate and authorize devices that do not support Dot1x. The switch
emulates the supplicant role on behalf of the non-Dot1x-capable devices,
and uses the MAC address of the devices as the username and password,
when communicating with the RADIUS servers. MAC addresses for Dell PowerConnect 55xx Systems User Guide 135
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxU_Switching_NetworkSecurity.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
username and password must be entered in lower case and with no
delimiting characters (for example: aaccbb55ccff). To use MAC-based
authentication at a port:
– A Guest VLAN must be defined.
– The port must be Guest-VLAN-enabled.
– The packets from the first supplicant, at the port before it is
authorized, must be untagged.
You can configure a port to use Dot1x only, MAC-based only, or Dot1x and
MAC-based authentication. If a port is configured to use both Dot1x and
MAC-based authentication, a Dot1x supplicant has precedence over a
non-Dot1x device. The Dot1x supplicant preempts an authorized, but
non-Dot1x device, at a port that is configured with a single session.
Unauthenticated VLAN and Guest VLANs
Unauthenticated VLANs and Guest VLANs provide access to services that do
not require the subscribing devices or ports to be Dot1x or MAC-Based
authenticated and authorized.
An unauthenticated VLAN is a VLAN that allows access by authorized and
unauthorized devices or ports. You can configure one or more VLAN to be
unauthenticated in the VLAN Membership pages in "VLANs" on page 466.
An unauthenticated VLAN has the following characteristics:
• It must be a static VLAN, and cannot be the Guest VLAN or the default
VLAN.
• The VLAN’s member ports must be manually configured as tagged
members.
• The member ports must be trunk and/or general ports. An access port
cannot be member of an unauthenticated VLAN.
The Guest VLAN, if configured, is a static VLAN with the following
characteristics.
• It must be manually defined from an existing, static VLAN.
• It is automatically available only to unauthorized devices, or to ports of
devices that are connected and Guest VLAN enabled. 136 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxU_Switching_NetworkSecurity.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• If a port is Guest-VLAN-enabled, the switch automatically adds the port as
an untagged member of the Guest VLAN when the port is not authorized,
and removes the port from the Guest VLAN when the first supplicant of
the port is authorized.
• The Guest VLAN cannot be used as both the Voice VLAN and an
unauthenticated VLAN.
The switch also uses the Guest VLAN for authentication at ports configured
with Multiple Session mode and MAC-based authentication. Therefore, you
must configure a Guest VLAN before you can use the MAC-based
authentication mode.
For authentication to function, it must be activated both globally, in the PortBased Authentication Global page and individually on each port, in the PortBased Authentication Interface Settings pages.
Monitoring Mode
Monitoring mode enables providing users who fail authentication with
limited network access. This enables these users to correct the reason that the
authentication failed.
The following are the main aspects of this feature:
• Enables successful authentications using the returned RADIUS
information
• Provides a mechanism to report unsuccessful authentications without
negative repercussions to the user due to administrator errors
• Accurately reports the data received from the successful and nonsuccessful operations so that appropriate changes to problem areas may be
made.
The Dot1x monitoring activation command includes a special VLAN that is
used when there is no access interface configuration present and the client(s)
unsuccessfully authenticates. These clients are placed in the special VLAN.
For users that unsuccessfully authenticate during re-authentication process,
but already have existing VLANs configured, the failure to authenticate does
not put them in a disabled state but places them back to the existing
configuration.Dell PowerConnect 55xx Systems User Guide 137

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Authorized — Places the interface into an authorized state
without being authenticated. The interface resends and receives
normal traffic without client port-based authentication.
• Unauthorized — Denies the selected interface system access by
moving the interface into unauthorized state. The device cannot
provide authentication services to the client through the
interface.
– Current Interface Control — Displays the current port authorization
state.
– Authentication Type — Select the type of authentication on the port.
The possible options are:
• 802.1x Only — 802.1X authentication is the only authentication
method performed on the port.
• MAC Only — Port is authenticated, based on the supplicant
MAC address. Only eight MAC-based authentications can be
used on the port.
• 802.1x & MAC — Both 802.1X and MAC-based authentication
are performed on the switch. The 802.1X authentication takes
precedence.
NOTE: For MAC authentication to succeed, the RADIUS server supplicant
username and password must be the supplicant MAC address. The MAC
address must be in lower case letters and entered without the “:” or “-”
separators; for example: 0020aa00bbcc.
– Dynamic VLAN Assignment — Enable/disable dynamic VLAN
assignment for this port. This feature enables you to automatically
assign users to VLANs during the RADIUS server authentication.
When a user is authenticated by the RADIUS server, the user is
automatically joined to the VLAN configured on a RADIUS server.
• Port Lock and Port Monitor should be disabled when DVA is
enabled.
• Dynamic VLAN Assignment (DVA) can occur only if a RADIUS
server is configured, and port authentication is enabled and set to
802.1x multi-session mode.
• If the RADIUS Accept Message does not contain the supplicant’s
VLAN, the supplicant is rejected.142 Dell PowerConnect 55xx Systems User Guide

• Authenticated ports are added to the supplicant VLAN as
untagged.
• Authenticated ports remain unauthenticated VLAN and Guest
VLAN members. Static VLAN configuration is not applied to the
port.
• The following list of VLANs cannot participate in DVA: an
Unauthenticated VLAN, a Dynamic VLAN that was created by
GVRP, a Voice VLAN, a Default VLAN and a Guest VLAN.
• Delete the supplicant VLAN while the supplicant is logged in.
The supplicant is authorized during the next re-authentication if
this supplicant VLAN is re-created, or a new VLAN is configured
on the RADIUS server.
NOTE: DVA provides the same functionality as the MAC to VLAN Assignment
feature, but does so in a standard way. Therefore, when DVA is available,
MAC to VLAN Assignment is not available.

The following is an example of the CLI commands:
Power over Ethernet
A Power over Ethernet (PoE) switch is a type of PSE (Power Sourcing
Equipment) that delivers electrical power to connected Powered Devices
(PDs) over existing copper cables, without interfering with the network
traffic, updating the physical network or modifying the network
infrastructure.
Using PoE eliminates the need to:
• Place all network devices next to power sources.
• Deploy double-cabling systems, significantly decreasing installation costs.
PoE can be used in any network that deploys relatively low-powered devices
connected to the Ethernet LAN. PDs are devices that receive power from the
PowerConnect power supplies, such as:
• IP phones

SNTP Overview
The switch supports the Simple Network Time Protocol (SNTP), which
provides accurate network switch clock time synchronization of up to 100
milliseconds. The implementation of SNTP is based on SNTPv4 (RFC 2030).
SNTP is a simple and lighter version of NTP, and can be used when the
ultimate performance of the full NTP implementation, described in
RFC-1305, is not required. SNTP operates with NTP, thus an SNTP client
can work with both SNTP and NTP servers.
The switch operates only as a client, and cannot provide time services to other
systems.
SNTP Server Types
The switch can accept time information from the following server types:
• Unicast
Polling for Unicast information is used for polling a server whose IP
address is known. This is the preferred method for synchronizing device
time, as it is most secure.
Up to eight SNTP servers can be defined.
If this method is selected, SNTP information is accepted only from SNTP
servers defined in the SNTP Servers page.
Time levels T1 - T4 (see the "Algorithm for Selecting Designated SNTP
Server" on page 180 section) are used to determine from which server time
information is accepted.
If Unicast polling is not enabled or if no servers are defined on the device,
the device accepts time information from any SNTP server of the type that
is enabled, which responds.
• Anycast
Polling for Anycast information is used when the SNTP server’s IP address
is not defined or it cannot be reached. If this method is enabled, time
information can be received from any SNTP server on the network. The Dell PowerConnect 55xx Systems User Guide 179
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
device time and date are synchronized when it proactively requests
synchronization information.
Anycast polling to get time information is preferable to Broadcast polling,
because it is more secure.
Time levels T3 and T4 are used to determine from which server time
information is accepted.
• Broadcast
Broadcast information is used if receiving Broadcast packets has been
enabled, and one of the following situations occurs:
– The SNTP server IP address has not been defined.
– Several time-information packets are received and the Broadcast time
is best according to the algorithm defined in "Algorithm for Selecting
Designated SNTP Server" on page 180.
Broadcast is the least secure method of receiving time, because it is both
unsecured and the time information was not specifically requested by the
device. Anycast is also unsecured, but time-information packets are only
accepted if they were requested.
Stratums
Each SNTP server is characterized by stratums, which define the accuracy of
its clock. The stratum is the distance, in terms of NTP hops, from the most
authoritative time server. The lower the stratum (where zero is the lowest),
the more accurate the clock. The switch accepts time from stratum 1 and
above.
The following provides examples of clocks from various stratums:
• Stratum 0 — A real time clock is used as the time source, for example, a
GPS system.
• Stratum 1 — A server that is directly linked to a Stratum 0 time source is
used.
• Stratum 2 — The time source is distanced from the Stratum 1 server over
a network path, for example, a Stratum 2 server receives the time over a
network link, via NTP, from a Stratum 1 server.180 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Algorithm for Selecting Designated SNTP Server
Messages received from SNTP servers are logged, until there are three
responding servers, or the timer expires. In any event, when the third message
is received, the timer expires.
A server is selected to be the “designated server” according to the following
criteria:
• The stratum (the distance in terms of NTP hops from the best
authoritative time servers) is considered, and the server with the best
(lowest) stratum is selected.
• If there is a tie in stratums, packets from servers defined on the device are
preferred to Anycast packets, which in turn are preferred to Broadcast
packets.
• If multiple servers pass the above criteria, then the server that sent the first
(earliest) time packet is chosen.
If a better server is discovered later, it is selected to be the “designated server”
at that time.
Polling
You can configure the system to acquire time information in the following
ways:
• Enable polling — Time information is requested every polling interval.
• Do not enable polling — Time information is received when the system is
brought up and every time that a topological change is made to the
Running Configuration file, for example when an SNTP Unicast server is
added.
This is configured by the user in the SNTP Global Settings page.
On power up, when the switch sends a request and there is no reply, it issues
another request (three retries at most) after 20 seconds of waiting.
If no SNTP server is found, the process is invoked every “poll interval” (set in
the SNTP Global Settings page), and a management trap is triggered.
Authentication
You can require that SNTP servers be authenticated, although this is not
mandatory (see the SNTP Authentication pages). Dell PowerConnect 55xx Systems User Guide 181
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
MD5 (Message Digest 5) Authentication safeguards device synchronization
paths to SNTP servers. MD5 is an algorithm that produces a 128-bit hash
value. MD5 is a variation of MD4, and increases MD4 security.
MD5 both verifies the integrity of the communication and authenticates the
origin of the communication.
Global Settings (Clock Source)
System time can be set manually, or it may be received from an external
SNTP server. You if wish to set the system time manually, you do not to use
the Global Settings page, because the default is manual (local) system time.

It contains the following topics:
• System Log Overview
• Global Parameters
• RAM Log
• Log File (in Flash)
• Login History
• Remote Log Server
System Log Overview
System logs record events and report errors or informational messages. Some
aspects of system logging can be configured, as described below. When you
configure system logging, the configuration applies to all units in the stack.
Some events are automatically logged, such as hardware problems. You may
enable/disable logging the following types of events:
• Authentication Events in the Global Parameters page
• Copy File Events in the Global Parameters page
• Management Access Events in the Global Parameters page
• Login History in the Login History page
Event messages have a unique format, as per the System Logs (SYSLOG)
protocol recommended message format for all error reporting, for example,
SYSLOG and local device reporting messages are assigned a severity code,
and include a message mnemonic that identifies the source application
generating the message.
Messages may be filtered, based on their urgency or relevancy.
Events may be logged to the following destinations:
• Console
• Logging buffer (RAM)— Messages are stored in a cyclical file buffer.
When the maximum number of messages is reached, messages are written
starting at the beginning of the buffer (overwriting the old messages). 196 Dell PowerConnect 55xx Systems User Guide

Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Logs stored on the Logging buffer are deleted when the device is reset.
• Logging file (flash) — Messages are stored in flash memory. When the
buffer is full, messages are written starting at the beginning of the memory
block (overwriting the old messages).
• SYSLOG Server — Messages are sent to a remote server. This is useful for
central and remote management and to provide more space for storage of
messages. Up-to eight SYSLOG servers can be defined in the Remote
Log Server Settings pages.
You can select where to send logging messages according to their severity.
Each of the severity level can be directed to the console, RAM log, flash log
file or SYSLOG server or to any combination of these destinations.
Global Parameters
Use the Global Parameters page to enable/disable logging for the following

– Emergency — If the device is down or not functioning properly, an
emergency log message is saved to the specified logging location.
– Alert — An alert log is saved if there is a serious device malfunction,
for example, all device features are down.
– Critical — A critical log is saved if a critical device malfunction
occurs, for example, two device ports are not functioning, while the
rest of the device ports remain functional.
– Error — A device error has occurred, for example, a single port is
offline.
– Warning — The lowest level of a device warning. The device is
functioning, but an operational problem has occurred.
– Notice — Provides device information to which you might have to
respond.
– Informational — Provides device information to which you do not
have to respond.

IP Addressing
This section describes how to configure IP addresses on the switch, and
contains the following topics:
• IP Addressing Overview
• IPv4 Interface Parameters
• DHCP IPv4 Interface
• IPv4 Static Routing
• IPv6 Interfaces
• IPv6 Default Gateway
• ISATAP Tunnel
• IPv6 Neighbors
• IPv6 Routes Table
• Domain Name System
• Default Domain Names
• Host Name Mapping
• ARP
• UDP Relay
IP Addressing Overview
The device functions as an IPv6-compliant host, as well as an IPv4-host (also
known as dual stack). This enables device operation in a pure-IPv6 network,
as well as in a combined IPv4/IPv6 network.
Difference Between IPv4 and IPv6 Addressing
The primary difference between IPv4 to IPv6 is the length of network
addresses. IPv6 addresses are 128 bits, whereas IPv4 addresses are 32 bits.
Thus, IPv6 addresses enable the use of many more unique addresses.
The 128-bit IPv6 address format is divided into eight groups of four
hexadecimal digits. Abbreviation of this format by replacing a group of zeros
with double colons (::) is acceptable. IPv6 address representation can be
further simplified by suppressing the leading zeros.210 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
All IPv6 address formats are acceptable, yet for display purposes, the system
displays the most abbreviated form, which replaces groups of zeros with
double colons and removes the leading zeros.
IPv6 Prefixes
While Unicast IPv6 addresses written with their prefix lengths are permitted,
in practice their prefix lengths are always 64 bits, and therefore are not
required to be expressed. Any prefix that is less than 64 bits is a route or
address range that summarizes a portion of the IPv6 address space.
For every assignment of an IP address to an interface, the system runs the
Duplicate Address Detection (DAD) algorithm to ensure uniqueness.
An intermediary transition mechanism is required for IPv6-only nodes to
communicate with IPv6 nodes over an IPv4 infrastructure. The tunneling
mechanism implemented is the Intra-Site Automatic Tunnel Addressing
Protocol (ISATAP). This protocol treats the IPv4 network as a virtual IPv6
local-link, with each IPv4 address mapped to a Link Local IPv6 address.
IPv4 Interface Parameters
You can assign IP addresses to the interface in the following ways:
• Manual Assignment — Described below
• DHCP Server Assignment — Described in "DHCP IPv4 Interface" on
page 214
Multiple IP addresses can be configured in the IPv4 Interface Parameters
pages. These IP addresses can be assigned to a port, LAG, or VLAN interface.
When an IP address is assigned, it is checked for uniqueness in the following
way:
• A gratuitous ARP request is sent three times every three seconds.
• If after (3+1)*3 = 12 seconds the switch has not received the ARP
response, the IP address is considered to be unique.
• During the procedure the switch has to reply to gratuitous ARP and probe
ARP requests with the validated IP address.Dell PowerConnect 55xx Systems User Guide 211
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
The IP address is assigned even if the above validation procedure concludes
that the IP address in question is not unique, but a SYSLOG message is
generated.
In addition to the above validation procedure every time a switch receives an
ARP request with a sender IP address that is equal to its IP address defined on
the input interface it sends a SYSLOG message informing of IP duplication,
containing the sender IP and MAC addresses, from the received ARP
message.
To assign an IP address to an interface, and to define subnets to which traffic

DHCP IPv4 Interface
The switch can operate in the following ways:
• It can function as a DHCP client that obtains its own IP from a DHCP
server, as described in this section
• It can function as a DHCP server that allocates IP addresses to other
devices, as described in "DHCP Server" on page 297
When the interface is configured as a DHCP client, it keeps requesting an IP
address from the DHCP server, until it receives one. It then sends Address
Resolution Protocol (ARP) packets to confirm the uniqueness of the IP
address. If the ARP response shows that the IP address is in use, the switch
sends a DHCPDECLINE message to the DHCP server, and sends another
DHCPDISCOVER packet that restarts the process.
IP address collisions occur when the same IP address is used in the same IP
subnet by more than one device. Address collisions require administrative
actions on the DHCP server and/or the devices that collide.
Up to 32 interfaces (ports, LAGs, and/or VLAN) on the switch can be
configured with a static or dynamic IP address. The IP subnets to which these
IP addresses belong are known as directly connected/attached IP subnets.
The IP address assignment rules for the switch are as follows:
• If the IP address on the switch is changed, the switch issues gratuitous
ARP packets to the corresponding VLAN, to check IP address collisions.
• When a client must renew its lease, prior to its expiration date, a
DHCPREQUEST message is sent.
• A specific interface can have either a static IP address or a dynamic IP
address, but not both.Dell PowerConnect 55xx Systems User Guide 215

• Link Local — The IP address is link local; non-routable and can
be used for communication on the same network only. A Link
Local address has a prefix of 'FE80'.
• Global Unicast — The IP address is a globally unique IPv6
Unicast address; visible and reachable from different subnets.
• Global Anycast — The IP address is a globally unique IPv6
Anycast address; visible and reachable from different subnets.
– IPv6 Address — Enter the IPv6 address assigned to the interface. The
address must be a valid IPv6 address, specified in hexadecimal using
16-bit values between colons. An example of an IPv6 address is
2031:0:130F:0:0:9C0:876A:130D and the compressed version is
represented as 2031:0:130F::9C0:876A:130D. Up to five IPv6
addresses (not including Link Local addresses) can be set per
interface, with the limitation of up to128 addresses per system.
– Prefix Length — For global Unicast or Anycast, enter the length of the
IPv6 prefix. The length is a decimal value that indicates how many of
the high-order contiguous bits of the address comprise the prefix (the
network portion of the address). The Prefix field is applicable only on a
static IPv6 address defined as a Global IPv6 address.
– EUI-64 — For global Unicast or Anycast, check to use the EUI-64

Use the IPv6 Default Gateway pages to configure and view the default IPv6
router addresses. This list contains routers that are candidates to become the
switch default router for non-local traffic. The switch randomly selects a
router from the list. The switch supports one static IPv6 default router.
Dynamic default routers are routers that have sent router advertisements to

The following are examples of these CLI command:
ISATAP Tunnel
To deliver IPv6 addresses in an IPv4 network, a tunneling process must be
defined that encapsulates IPv6 packets in IPv4 packets.
The Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an IPv6
transition mechanism that is used to transmit IPv6 packets between
dual-stack nodes (nodes that can accept both IPv4 and IPv6 addresses) on top
of an IPv4 network.
When enabling ISATAP on a tunnel interface, an explicit IPv4 address is
configured as the tunnel source, or an automatic mode exists, where the
lowest IPv4 address is assigned to an IP interface. This source IPv4 address is
used for setting the tunnel interface identifier according to ISATAP
addressing conventions. When a tunnel interface is enabled for ISATAP, the
tunnel source must be set for the interface in order for the interface to
become active.
An ISATAP address is represented using the [64-bit prefix]:0:5EFE:w.x.y.z,
where 5EFE is the ISATAP identifier and w.x.y.z is a public or private IPv4
address. Thus, a Link Local address will be represented as FE80::5EFE:w.x.y.z

After the last IPv4 address is removed from the interface, the ISATAP IP
interface state becomes inactive and is represented as Down, however the
Admin state remains Enabled.
When defining tunneling, note the following:
• An IPv6 Link Local address is assigned to the ISATAP interface. The initial
IP address is assigned to the interface, and the interface state becomes
Active.
• If an ISATAP interface is active, the ISATAP router IPv4 address is resolved
via DNS by using ISATAP-to-IPv4 mapping. If the ISATAP DNS record is
not resolved, the ISATAP host name-to-address mapping is searched in the
host name cache.
• When an ISATAP router IPv4 address is not resolved via the DNS process,
the status of the ISATAP IP interface remains Active. The system does not
have a default gateway for ISATAP traffic until the DNS procedure is
resolved.
• In order for an ISATAP Tunnel to work properly over an IPv4 network, an
ISATAP router is must be set up.Dell PowerConnect 55xx Systems User Guide 231

• Telnet (CLI over Telnet sessions)
• Secure Telnet
• Web (HTTP)
• Secure Web (HTTPS, Using SSL)
• SNMP 262 Dell PowerConnect 55xx Systems User Guide

This means, for example, that the set of managers allowed via Telnet may be
different than the set of Web-based managers which is, in turn, may be
different than the set of secure-web based managers, and so on.
A specific management access method may be completely disabled by
denying all user access to it (e.g. denying all users access to CLI/Telnet
management effectively disables CLI/Telnet as an available management
interface to the system).
By default, management access to the system, through all methods, is
enabled over all interfaces.
NOTE: If you enable management access through a physical port, all VLANs and
IP interfaces on that port will be acceptable management traffic sources. If you
enable management access through a VLAN, all ports and IP interfaces on that
VLAN will be acceptable. If specific IP address(es) are specified, only traffic from
the specified IP addresses on the appropriate ports will be accepted.
Access Profiles Rules
Each management access profile is composed of at least one rule, which acts
as a filter, and defines the device management method, interface type, source
IP address, network mask, and the device management access action.
Users can be blocked or permitted management access.
Rule priority sets the order in which the rules are implemented. Assigning an
access profile to an interface denies access via other interfaces. If an access
profile is not assigned to any interface, the device can be accessed by all
interfaces.
A total of 256 rules can be defined for all Management Access profiles.
To add rules to existing access profiles, see "Profile Rules" on page 266.Dell PowerConnect 55xx Systems User Guide 263

Authentication Profiles
In addition to access profiles, you can configure authentication for
management access methods, such as SSH, console, Telnet, HTTP, and
HTTPS.
User authentication can occur:
• Locally
• Via an external server, such as a TACACS+ or a RADIUS server
User authentication occurs in the order that the methods are selected, for
example, if both the Local and RADIUS options are selected, the user is
authenticated first locally. If the local user database is empty, the user is
authenticated via the RADIUS server.
If an error occurs during the authentication, the next selected method is
used.
If an authentication method fails, or the user has an insufficient privilege
level, the user is denied access to the switch. The switch then stops, does not
continue, and does not attempt to use the next authentication method.
If a privilege level is redefined, the user must also be re-defined.
User authentication can also be set to None, in which case no authentication
is performed.
The process of configuring authentication for management access methods is
divided into the following stages:
• Create an authentication profile, as described below
• Assign an authentication profile to a management method, as described in

Password aging starts immediately after password management is enabled.
However it is only effective if system time on the device is taken from an
SNTP server. Passwords expire according to the user-defined expiration
date/time. Ten days prior to password expiration, the device displays a
password expiration warning message.
After the password has expired, users can log in a few additional times.
During the remaining logins, an additional warning message displays
informing the user that the password must be changed. If the password is not
changed, users are locked out of the system, and can only log in using the
console. Password warnings are logged in the SYSLOG file.

The DHCP server can allocate IP addresses in the following modes:
• Static Allocation — The hardware address of a host is manually mapped
to an IP address.
• Permanent Allocation — An IP address sent to the client through a
standard request-reply mechanism, is owned by that client permanently
(unless changes in the network environment/connections take place, for
any reason).
• Dynamic Allocation — A client obtains a leased IP address for a specified
period of time. The IP address is revoked at the end of this period, and the
client must request another IP address. 298 Dell PowerConnect 55xx Systems User Guide

DHCP Server Properties
If the device is configured to act as a DHCP server, pinging capability can be
enabled. The DHCP server pings an IP address in the address pool before
assigning that IP address to a requesting client. If the ping is unanswered, the
DHCP server assumes that the address is not in use and assigns the address to
the client.
To configure the device as a DHCP server:

• Network Mask — Check and enter the pool’s network mask.
• Prefix Length — Check and enter the number of bits that
comprise the address prefix.
– Address Pool Start — Enter the first IP address in the range of the
network pool.
– Address Pool End — Enter the last IP address in the range of the
network pool.
– Lease Duration — Enter the amount of time a DHCP client can use
an IP address from this pool. The total lease duration is 4294967295
seconds, i.e. 49710.2696 days. Thus a lease of 49710 days, 0 hours, 0
minutes and 0 seconds is a legal value, while a lease of 49710 days, 23
hours, 59 minutes and 59 seconds results in an Out of Range alert.
• Days — The duration of the lease in number of days. The range is
0 to 49710 days.
• Hours — The number of hours in the lease. A days value must be
supplied before an hours value can be added.
• Minutes — The number of minutes in the lease. A days value and
an hours value must be added before a minutes value can be
added.
• Infinite — The duration of the lease is unlimited.
– Default Router — Enter the default router for the DHCP client.
– Domain Name Server — Enter the DNS server available to the DHCP
client.
– Domain Name — Enter the domain name for a DHCP client. The
domain name may contain up to 32 characters.
– NetBIOS WINS Server — Enter the NetBIOS WINS name server
available to a DHCP client.
– NetBIOS Node Type — Select how to resolve the NetBIOS name.

• Peer-to-Peer — Point-to-point communications with a NetBIOS
name server are used to register and resolve computer names to IP
addresses.
• Mixed — A combination of b-node and p-node communications
is used to register and resolve NetBIOS names. M-node first uses
b-node; then, if necessary, p-node. M-node is typically not the best
choice for larger networks because its preference for b-node
Broadcasts increases network traffic.
• Hybrid — A hybrid combination of b-node and p-node is used.
When configured to use h-node, a computer always tries p-node
first and uses b-node only if p-node fails. This is the default.
– SNTP Server — Enter the IP address of the time server for the DHCP
client.
– Next Server — Enter the IP address of the next server in the boot
process of a DHCP client. If the next server in the boot process is not
configured, the DHCP server uses inbound interface helper addresses
as boot servers.

SNMP
This section describes the Simple Network Management Protocol (SNMP)
for managing network devices.
It contains the following topics:
• SNMP Overview
• SNMP Global Settings
• SNMP Views
• SNMP Access Control (Groups)
• SNMP User Security Model (Users)
• SNMP Communities
• SNMP Notification Filters
• SNMP Notification Recipients
SNMP Overview
The switch supports the SNMPv1, SNMPv2 and SNMPv3.
SNMP v1 and v2
The SNMP agent maintains a list of variables that are used to manage the
switch. These variables are stored in the Management Information Base
(MIB) from which they may be presented. The SNMP agent defines the MIB
specification format, as well as the format used to access the information over
the network. Access rights to the SNMP agents are controlled by access
strings.
SNMPv1 and v2 are enabled by default.
SNMP v3
In addition to the features provided by SNMPv1 and SNMPv2, SNMPv3
applies access control and a new trap mechanism to SNMPv1 and SNMPv2
PDUs. In addition, a User Security Model (USM) can be defined, which
includes:
• Authentication — Provides data integrity and data origin authentication. Dell PowerConnect 55xx Systems User Guide 315
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Privacy — Protects against disclosure of message content. Cipher BlockChaining (CBC) is used for encryption. Either authentication alone can
be enabled on an SNMP message, or both authentication and privacy can
be enabled on an SNMP message. However privacy cannot be enabled
without authentication.
• Timeliness — Protects against message delay or message redundancy. The
SNMP agent compares incoming message to the message time
information.
• Key Management — Defines key generation, updates, and use.
The switch supports SNMP notification filters, based on Object IDs (OIDs),
which are used by the system to manage switch features.
Authentication or Privacy Keys are modified in the User Security Model
(USM).
SNMPv3 can only be enabled if the Local Engine ID is enabled.
SNMP Access Rights
Access rights in SNMP are managed in the following ways:
• SNMPv1 and SNMPv2 — Communities
The community name is a password sent by the SNMP management
station to the device for authentication purposes.
A community string is transmitted along with the SNMPv1,v2 frames, but
neither the frames nor the community string are encrypted. Since
SNMPv1 and SNMPv2 are not encrypted, they are not secure.
Communities can be associated with views or groups, and they are defined
in the Community pages.
• SNMPv3 — Users and Groups
SNMP v3 works with users instead of communities. The users belong to
groups that have access rights assigned to them. Users are defined in the
User Security Model pages
SNMPv3 provides two security mechanisms:
– Authentication — The switch checks that the SNMP user is an
authorized system administrator. This is done for each and every
frame. 316 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
– Privacy — SNMP frames can carry encrypted data.
These mechanisms can be combined to provide three levels of security:
– No security
– Authentication
– Authentication and Privacy. Note that for both authentication and
privacy to be enabled, two groups with the same name, one with
authentication and one with privacy, must be created.
A group is a label for a combination of attributes that determines whether
members have read, write, and/or notify privileges. Users can be associated
with a group. A group is operational only when it is associated with an
SNMP user.
Model OIDs
The following are the switch model Object IDs (OIDs):
SNMP Global Settings
The Engine ID is used by SNMPv3 entities to uniquely identify themselves.
An SNMP agent is considered an authoritative SNMP engine. This means
that the agent responds to incoming messages (Get, GetNext, GetBulk, Set),
and sends Trap messages to a manager. The agent's local information is
encapsulated in fields in the message.
Each SNMP agent maintains local information that is used in SNMPv3
message exchanges (not relevant for SNMPv1 or SNMPv2). The default
SNMP Engine ID is comprised of the enterprise number and the default
MAC address. The SNMP engine ID must be unique for the administrative
domain, so that no two devices in a network have the same engine ID.

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
The local information is stored in four read-only MIB variables:
snmpEngineId, snmpEngineBoots, snmpEngineTime, and
snmpEngineMaxMessageSize.
To configure SNMP:
1 Click System > SNMP > Global Parameters in the tree view to display
the Global Parameters page.
Figure 9-47. Global Parameters
The global parameters are displayed.
2 Enter the fields:
– Local Engine ID (10-64 Hex Characters) — Check and enter the
local device engine ID. The field value is a hexadecimal string. Each
byte in hexadecimal character strings is two hexadecimal digits. Each
byte can be separated by a period or a colon. The Engine ID must be
defined before SNMPv3 is enabled.
For stacked devices, verify that the Engine ID is unique for the
administrative domain. This prevents two devices in a network from
having the same Engine ID. 318 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
– Use Default — Check to use the device-generated Engine ID. The
default Engine ID is based on the device MAC address, and is defined
per standard as:
• First 4 octets — First bit = 1, the rest is IANA Enterprise number
= 674.
• Fifth octet — Set to 3 to indicate the MAC address that follows.
• Last 6 octets — MAC address of the device.
– SNMP Notifications — Enable/disable the switch sending SNMP
notifications.

SNMP Access Control (Groups)
For ease of use, users may be assigned to groups. In this way, it is possible to
assign feature access rights to an entire group, instead of assigning them
individually to users. Users are created in the User Security Model pages.
Groups can be defined in any version of SNMP, but only SNMPv3 groups can
be assigned authentication methods.
To add an SNMP group, and assign it access control privileges:

The following is an example of the CLI commands:
SNMP User Security Model (Users)
An SNMP user is defined by the following:
• Login credentials (username, password, and authentication method)
• Context and scope in which the user operates
• Association with a group
• Engine ID
SNMP user login credentials are verified using a local database.
After a user is authenticated, it takes on the attributes of its group, and can
then access the views permitted to this group. A user can only be a member of
a single group.
Before you create an SNMPv3 user, create an SNMPv3 group in the Access
Control pages.
When the configuration file is saved, SNMP communities/users are not
saved. This means that if you configure another device with this
configuration file, you must define the SNMP communities/users on that
device.

SNMP Notification Recipients
An SNMP notification is a trap message, sent from the switch to the SNMP
management station, indicating that a certain event has occurred, such as a
link up or down.
Trap receivers, also known as notification recipients, are network nodes to
which trap messages are sent by the switch.
A trap receiver entry contains the IP address of the node and the SNMP
credentials corresponding to the version that will be included in the trap
message. When an event arises that requires a trap message to be sent, it is
sent to every node listed in the trap receiver list.
Some messages are of an informational nature and are called "informs"
instead of traps.

File Management
This section describes how to manage device firmware (image files) and
configuration files.
It contains the following topics:
• File Management Overview
• Auto-Update/Configuration Feature
• File Download
• File Upload
• Active Images
• Copy Files
• File System
File Management Overview
This section describes the system files found in the system and how they can
be updated (downloaded) and backed up (uploaded).
System Files
The following system files are maintained on the system:
• Startup Configuration File — Files with extension .text. These files
contain the commands required to configure the device at startup or after
reboot. The Startup Configuration file is created from the Running
Configuration file, or can be created from another file.
• Running Configuration File — Files with extension .text. These files
contain all Startup Configuration file commands, as well as all commands
entered during the current session. After the device is powered down or
rebooted, all commands stored in the Running Configuration file are lost.
During the startup process, all commands in the Startup Configuration
file are copied to the Running Configuration file, and applied to the
device.
During the session, new configuration commands are added to the
Running Configuration file. To update the Startup Configuration file with
these configuration commands, the Running Configuration file must first
be copied to the Startup Configuration file before powering down the 338 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
device. This can be done manually in the Copy Files page or see "AutoUpdate/Configuration Feature" on page 338 for more information about
how to perform this automatically.
• Image Files—Files with extension .ros. System file images are saved in two
flash files called Image 1 and Image 2. The active image contains the
active copy, while the other image contains a backup copy. The device
boots and runs from the active image. If the active image is corrupted, the
system automatically boots from the non-active image. This is a safety
feature for faults occurring during the software upgrade process.
Downloading/Uploading System Files
System files can be manually loaded from (downloaded) or copied to
(uploaded) a TFTP server or a USB drive. This can be done in one of the
following ways:
• Manually—System files can be downloaded using the File Download page
and uploaded using the File Upload page.
• Automatically (Auto Update/Configuration)—System files can be
downloaded automatically, as follows:
– Auto-Configuration—If the Auto-Configure feature is enabled (in the
Auto Update of Configuration/Image File page), the Startup
Configuration file (in various conditions described below) might be
automatically updated after reboot.
– Auto-Update—If the Firmware Auto-Update feature is enabled in the
Auto Update of Configuration/Image File page, the image file is might
be automatically updated (in various conditions described below).
Auto-Update/Configuration Feature
The Auto-Update/Configuration feature enables initial configuration of the
device and upgrading of the firmware through an automatic process, which
enables the administrator to ensure that the configuration/firmware of all the
devices in the network is up-to-date. Dell PowerConnect 55xx Systems User Guide 339
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
The required configuration files/images are stored on a USB key or TFTP
server, and these are downloaded to all the devices in the network when the
device boots up instead of booting from a local startup configuration file.
Auto-Update/Configuration also enables quick installation of new devices on
the network, since an out-of-box device can be configured to retrieve its
configuration file from the network/USB, allowing instant access to it from
the administrator's management station and up-to-date configuration on the
device.
NOTE: If Auto-Update is performed through the USB port, in addition to upgrading
the Startup Configuration and image file, a new IP address can also be assigned
to the device. See "Setup Files" on page 339 below.
Setup Files
In addition to placing configuration and image files on the USB key, the USB
key might also contain a setup file, which is a file with a .setup extension.
Setup File Contents
A setup file contains one or more lines. Each line contains some or all of the
following fields:
• MAC Address—This indicates to which device the line applies. In this
way, a single setup file can be used for multiple devices.
• New IP Address—The new IP address to be assigned to the device.
• New IP Address Mask—The IP address mask to be applied to the new IP
address assigned to the device.
• Configuration File Name—Name of the configuration file to be used as
the Startup Configuration.
• Image File Name—Name of the image file to be loaded on device.
• Flag—Indicates the status of the line. The following values can be used in
this field:
– In-Use—This line has already been applied. It is no longer a candidate
for future use.
– Invalid—The line is invalid, do not use.
– Blank—There is no value for the flag field. This line is a candidate to
be applied to the device.340 Dell PowerConnect 55xx Systems User Guide

Triggering the Auto-Update/Configuration Process
When the Auto-Update/Configuration feature is enabled (in the Auto
Update of Configuration/Image File page), the device automatically attempts
to download a new image or configuration file (under certain circumstances)
using one of the following processes:
• The Auto-Update process is triggered from the USB drive if a USB key in
the USB drive is found.
• The Auto-Configuration process is triggered from the USB drive after the
Auto-Update process completed and the device was rebooted (if a new
image file was loaded), and if the following conditions are fulfilled:
– There is a USB key in the USB drive.
– Force Configuration Download at Next Startup has been enabled by
the boot host dhcp command, or the Startup Configuration file is
empty.
See "Performing Auto-Update from a USB Drive" on page 343.
• The Auto-Update from a TFTP server is triggered if the following
conditions are fulfilled:
– The conditions for a USB Auto-Update are not fulfilled.
– An IP address of a TFTP server is received from a DHCP server.
– A file name is received from DHCP server.
• The Auto-Configuration from a TFTP server is triggered if the following
conditions are fulfilled:
– The conditions for USB Auto-Configuration are not fulfilled.
– The switch as DHCP client received a configuration file name or a
TFTP URL.
– Force Configuration Download at Next Startup enabled by the boot
host dhcp command, or, the Startup Configuration file is empty.
See "Preparations for Using Auto Configuration from a TFTP Server" on
page 345.
NOTES:
• DHCP client never triggers the Auto-Update process from a TFTP server
after attempting (whether successfully or not) to auto-update/configure
configuration/image file from the USB drive. Dell PowerConnect 55xx Systems User Guide 343

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• If the auto process involved setting the IP address of the device from the
setup file, the auto process from the TFTP server can be triggered.
• If the USB drive contains a setup file, but that setup file does not include a
line that can be used for the current device, the DHCP client is able to
trigger the Auto-Update process from TFTP (because the USB process
never started at all).
Automatic DHCP IP Interface Assignment
The user can manually define a DHCP interface in the DHCP IPv4 page.
If the user does not do this, the switch automatically creates a DHCP
interface on the VLAN with the lowest VLAN ID that does not have an IP
address defined on it after boot if both of the following conditions are
fulfilled:
• There is no DHCP IP interface.
• There is a VLAN without an IP address.
Preparations for Using Auto Update/Configuration from a USB Drive
Before Auto-Update/Configuration from a USB drive can be performed, the
following steps must be performed:
1. Enable Auto-Update/Configuration in the Auto Update of
Configuration/Image File page.
2. (Optional) Create a line in the setup file for this device containing the
required options and load it on the USB key.
3. Load configuration/image files on the USB key as required.
4. Insert the USB key in the USB drive and reboot the device.
Performing Auto-Update from a USB Drive
When Auto-Update is initiated from a USB drive, the following steps are
performed:
1. Locate the correct setup file—The USB drive is searched for a setup file.
One of the following can occur:
– Setup file is not found—The root folder of the USB is searched for an
image files (with .ros extension).
• The image file with the most recent version is loaded into the
image file if the versions are different.344 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• If a new image file was loaded, the device is rebooted.
• The USB drive is searched for a configuration file (.text
extension). If there is more than one configuration file, the file
named powerconnect.text is loaded (if it is not found the process
is stopped).
– One or more setup files are found—If a single setup file is found, it is
used; if several files are found, the file powerconnect.setup is used. If
no setup file with this name is found, the process is stopped.
2. Find the line in the setup file relevant to the device—When the correct
setup file is found, it is searched for a line relevant to the device, as
follows:
– The setup file is searched for a line with format A or B in which there
is a match to the device's MAC address. If such line is found, and its
format is valid (the field is empty), the line is applied.
– If no line for the specific device was found, the setup file is searched
for valid lines with formats C or D. The first line found is applied.
3. Apply the correct line—When the correct line in the setup file is found,
it is applied, as follows:
– If the line contains an IP address and IP mask, the IP address is
configured on the default VLAN.
– If the line contains an image file and its version differs from the
current image file version, the USB image file is loaded and the switch
is rebooted.
– If a new image file was loaded, it is loaded onto all units in the stack.
– If the line contains a configuration file, the configuration file is
appended to running configuration file.
4. Mark the flag in the applied line—When the line is applied (successfully
or not), its flag is set, as follows:
– If the line contains an IP address and IP mask (format C or D), the IP
address is configured on the default VLAN and the line is marked as
"in-use". This ensures that the line is not used for another device.
– If the line was not applied successfully, for one of the following
reasons, the line is marked as "invalid" and a SYSLOG message is sent.Dell PowerConnect 55xx Systems User Guide 345
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• The configuration file specified by the line does not exist on the
USB key or is corrupted.
• The image file specified by the line does not exist on the USB key
or is corrupted.
– If parsing of the line failed for some other reason, the line is ignored
and a SYSLOG message is sent.
NOTE: When both Auto-Update and Auto-Configuration are performed, the image
file is loaded first, the device is booted and then the configuration file is loaded.
Preparations for Using Auto Configuration from a TFTP Server
The Auto-Update/Configuration feature enables configuring the device from
a configuration file found on the TFTP server.
Two methods may be used:
• One-file Read, described in "Auto Configuration (One File Read Method)"
on page 345. This method is used if a configuration file is found on the
TFTP server.
• Multi-file Read, described in "Auto Configuration (Multi File Read
Method)" on page 346. This method is used if a configuration file name is
not found on the DHCP server, or the configuration file is not found on
the TFTP server.
Auto Configuration (One File Read Method)
This method requires the following preparations on the DHCP and TFTP
servers:
• TFTP Server
Place a configuration file, for example config.txt in the main directory.
This file can be created by copying a configuration file from a device.
When the device is booted this becomes the Running configuration file.
• DHCP Server
– Configure the DHCP server with option 67 and the name of the
configuration file on the TFTP server (for example, config.txt).
– Configure the DHCP server with option -20 or 66. This is the IP
address of the TFTP server.346 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSystemConfig.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Device - On the device, one of the following cases may exist:
– If Configuration Auto-Config is selected, the device is configured
with the configuration file on the TFTP server only if the Startup
configuration file is empty.
– If Force Configuration Download at Next Startup is selected, the
device is configured with the configuration file on the TFTP server
whether the Startup configuration file is not empty or not.
Auto Configuration (Multi File Read Method)
If the one-file method has failed and the TFTP Server IP address has been
provided by the DHCP Server, the switch applies the multi-file method to
download the configuration file. The following steps are performed by the
switch:
• The switch gets the hostname, as described below.
– If the hostname was provided by the DHCP server, this hostname is
used.
– If the hostname has not been provided by a DHCP server, and if the
user has configured the sysName variable, its value is used as a
hostname.
– If neither of the above occurred, the switch uses the fp-net.cfg
Filename List on the TFTP server. Each file in this list is a text file
containing commands, each of which:
• Occupies one line.
• Has the following format: ip host hostname ip-addr. Each line
maps an IP address to a hostname. When the switch identifies its
own IP address in this list, the hostname associated with it is used.
• The switch tries to download a configuration file with the following names:
– hostname-config
– hostname.cfg if the previous file does not exist
– host.cfg if the previous files do not existDell PowerConnect 55xx Systems User Guide 347

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Preparations for Firmware Image Download from TFTP
The image file download consists of the following steps:
• The switch downloads the Indirect Image File and extracts from it the
name of the image file.
Note: If the size of the image name bigger than 160 octets only the first
160 octets will be used
• If the image file version differs from the current image file version, then
the image file is loaded and the switch is rebooted.
The preparations on the DHCP and TFTP servers require the following:
• TFTP Server
– Create a sub directory in the main directory. Place a software image
file in it.
– Create an indirect file that contains a path and the name of the
software version (for example indirect-contax.txt that contains
contax\contax-version.ros).
– Copy this file to the TFTP server’s main directory
• DHCP Server
– Configure the DHCP server with option -20 or 66. This is the IP
address of the TFTP server.
– Configure the DHCP server with option 125. Enter the following
information:
• A2-02-00-00 — Enterprise Number 674 (Dell PowerConnet 55xx
value). It should be written from right to left. 674=02 a2
• 15 — Data Length
• 01 — Sub option code 1 (Dell PowerConnet 55xx value)
• 13 — Sub option length
• Conversion of the file name (in the above example: conversion of
indirect-contax.txt from ASCII to HEX - 69-6E-64-69-72-65-63-

Auto Update Configuration through the GUI
To set the auto update and configuration parameters:
. NOTE: For the automatic options in this page to work the following must be
implemented:
• Since Auto-Config depends on retrieving information from a DHCP server, the
startup configuration needs to include a DHCP IP interface. The device is
defined as a DHCP client, as described in "DHCP IPv4 Interface" on page 214.
After reboot, this command is not saved in the Startup configuration.
• Preparations described above must be completed on the DHCP server and
TFTP servers.

• Unit Identification (Location)
Stack Management Overview
A stack consists of up to eight units, with support for up to 400 network ports.
Unit 1 usually acts as the stack master and Unit 2 is the backup master. All
other units act as slaves.
The entire stack, without regard to the stack topology or the number of units
in the stack, can be managed as a single switch.
For more information about stacking, see "Stacking Overview" on page 45.
The stacking pages described in this section enable the following actions:
• Switching from the Master unit to the Backup Master unit
• Changing unit IDs
• Viewing hardware and software versions on each unit
• Resetting either a unit or all the units in the stack
• Setting the Location LED on a unit(s)

sFlow
This section describes sFlow monitoring of traffic.
It contains the following sections:
• sFlow Overview
• Workflow
• sFlow Receiver Settings
• sFlow Interface Settings
• sFlow Statistics
sFlow Overview
The sFlow feature enables collecting statistics using the sFlow sampling
technology, based on sFlow V5.
This sampling technology is embedded within switches and routers. It
provides the ability to continuously monitor traffic flows on some or all the
interfaces, simultaneously.
The sFlow monitoring system consists of an sFlow agent (embedded in a
switch or router or in a stand alone probe) and a central data collector, known
as the sFlow receiver.
The sFlow agent uses sampling technology to capture traffic and statistics
from the device it is monitoring. sFlow datagrams are used to forward the
sampled traffic and statistics to an sFlow receiver for analysis.
sFlow V5 defines:
• How traffic is monitored.
• The sFlow MIB that controls the sFlow agent.
• The format of the sample data used by the sFlow agent when forwarding
data to a central data collector. The device provides support for two types
of sFlow sampling: flow sampling and counters sampling. The following
counters sampling is performed according to sFlow V5 (if supported by
the interface):
– Generic interface counters (RFC 2233)
– Ethernet interface counters (RFC 2358)376 Dell PowerConnect 55xx Systems User Guide

Workflow
By default, flow and counter sampling are disabled.
To enable sFlow sampling:
1 Set the IP address of a receiver (also known as a collector) for sFlow
statistics. Use the sFlow Receivers Settings page for this.
2 Enable flow and/or counter sampling, direct the samples to a receiving
interface, and configure the average sampling rate. Use the sFlow
Interface Settings pages for this.

Overview
This section includes a description of port features and describes the
following:
• Auto-Negotiation
• MDI/MDIX
• Flow Control
• Back Pressure
• Port Default Settings
Auto-Negotiation
Auto-negotiation enables automatic detection of speed, duplex mode and
flow control on all switching 10/100/1000BaseT ports. Auto-negotiation is
enabled on all ports by default.
Auto-negotiation is a mechanism established between two link partners to
enable a port to advertise its transmission rate, duplex mode and flow control
abilities to its partner. Both ports then operate at the highest common
denominator.
If connecting a Network Interface Card (NIC) that does not support autonegotiation or is not set to auto-negotiation, both the device switching port
and the NIC must be manually set to the same speed and duplex mode.
If the station, on the other side of the link, attempts to auto-negotiate with a
device 100BaseT port that is configured to full duplex, the auto-negotiation
results in the station attempting to operate in half duplex.
MDI/MDIX
The device supports auto-detection of straight-through and crossed cables on
all 10/100/1000BaseT ports. This feature is part of auto-negotiation and is
enabled when Auto-negotiation is enabled.
When the MDI/MDIX (Media Dependent Interface with Crossover) is
enabled, the automatic correction of errors in cable selection is possible, thus
making the distinction between a straight-through cable and a crossover cable 386 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
irrelevant. The standard wiring for end stations is known as MDI (Media
Dependent Interface), and the standard wiring for hubs and switches is known
as MDIX.
Flow Control
The device supports 802.3x flow control for ports configured to Full Duplex
mode. By default, this feature is enabled on all ports, and it can be disabled
per port.
Flow control creates a lossless link with no packet loss. The flow control
mechanism enables the receiving side to signal to the transmitting side that
transmission must temporarily be halted to prevent buffer overflow. This
signaling is done by sending PAUSE frames. The ports that receives pause
frames stops transmitting traffic.
Flow control on the device works in Receive-Only mode, meaning that the
interfaces with enabled flow control receive PAUSE frames, but do not send
them.
When flow control is enabled, the system buffers are allocated per port so
that if the buffers of one port are consumed, other ports will still have their
free buffers.
Back Pressure
The device supports back pressure for ports configured to Half Duplex mode.
By default, this feature is disabled, and it can be enabled per port. The
back-pressure mechanism prevents the sender from transmitting additional
traffic temporarily. The receiver may occupy a link so it becomes unavailable
for additional traffic.

Green Ethernet Configuration
Green Ethernet is a name of a set of features that are designed to reduce the
power consumption of a device, and so make it environmentally friendly.
The Green Ethernet feature reduces overall power usage in the following
ways:
• Energy Efficient Ethernet — When using EEE, systems on both sides of
the link can disable portions of their functionality and save power during
periods of low link utilization. EEE is a hardware feature that is enabled by
default, and is transparent to users. This feature is defined per port,
regardless of their LAG membership.
• Short-Reach Mode — Power usage is adjusted to the actual cable length.
In this mode, the VCT (Virtual Cable Tester) length test is performed to
measure cable length. If the cable is shorter than a predetermined length,
the switch reduces the power used to send frames over the cable, thus
saving energy. This mode is only supported on RJ45 ports.
Power savings and current power consumption in Short Reach mode can
be monitored. The total amount of saved energy can be viewed as a
percentage of the power that would have been consumed by the physical
interfaces had they not been running in Green Ethernet mode.Dell PowerConnect 55xx Systems User Guide 391

Protected Ports
Protected Port Overview
Protected ports provide Layer 2 isolation between interfaces (Ethernet ports
and LAGs) that share the same Broadcast domain (VLAN) with other
interfaces. This can be used to set up a group of ports that receive similar
services.
A protected port does not forward traffic (Unicast, Multicast, or Broadcast) to
any other protected port on the same switch.
A community is a group of protected ports. Protected ports within the same
community can forward traffic to each other.
The following types of ports can be defined:
• Protected Port — Can send traffic only to uplink ports.
• Community Port — A protected port that is associated with a community.
It can send traffic to other protected ports in the same community and to
uplink ports.
• Uplink Port — An uplink port is an unprotected port that can send traffic
to any port.
• Isolated Port — A protected port that does not belong to a community.
Port Protection is independent of all other features and configuration
settings. Two protected ports in a common VLAN cannot communicate with
each other.
Protected Port Restrictions
The following restrictions apply to protected ports:
• When a protected port is placed in a LAG, it loses its protected port
attribute and takes upon itself the LAG's protection attributes. When the
port is removed from the LAG, its attributes are re-applied.
• Mirrored traffic is not subject to protected ports rules.
• Routing is not affected by the protected port forwarding rule, so that if a
packet enters a protected port, it can be routed by the device to another
protected port.Dell PowerConnect 55xx Systems User Guide 395

Port Profile
Port profiles provide a convenient way to save and share a port configuration.
When a port profile, which is a set of CLI commands having a unique name,
is applied to a port, the CLI commands contained within the profile (macro)
are executed and added to the Running Configuration file.
Port profiles can be applied to a specific interface, a range of interfaces, or
globally.
There are two types of port profiles:
• User Defined — Enables the user to bundle configurations, as a port
profile, and then apply it to one or more interfaces at a time. Up to 20
user-defined macros can be supported. These can only be defined through
CLI commands.
• Built-In — Pre-defined macros that cannot be changed or deleted. The
device includes the following built-in macros:
– Global
– Desktop
– Phone
– Switch
– Router
– Wireless Configuration
Before a built-in profile can be applied to an interface, the global profile must
be applied. The global profile enables QoS Advanced mode, sets Advanced
mode parameters, CoS to queue mapping, and DSCP to queue mapping and
defines certain standard ACLs. Use the CLI command show parser macro
name profile-global to display the Global profile contents.398 Dell PowerConnect 55xx Systems User Guide

The remaining fields on this page are display-only, and describe the port
configuration of the profile. The following fields are described:
Port Security fields:
– Mode — Learning mode. The possible options are:
• Classic Lock — Locks the port using the classic lock mechanism.
The port is immediately locked, regardless of the number of
addresses that have already been learned.
• Limited Dynamic Lock — Locks the port by deleting the
dynamic MAC addresses associated with the port. The port learns
up to the maximum addresses allowed on the port. Both
relearning and aging MAC addresses are enabled.
– Max Entries — Displays the maximum number of MAC addresses
that can be learned on the port.
– Action on Violation — Action to be applied to packets arriving on a
locked port. The possible options are:
• Discard — Discard the packets from any unlearned source.
• Forward — Forward the packets from an unknown source,
without learning the MAC address.
• Shutdown — Discard the packet from any unlearned source, and
shut down the port. Ports remain shutdown until they are
reactivated, or the device is reset.
Spanning Tree fields:
– Point-to-Point Admin Status — Displays whether a point-to-point
links is established. The possible options are:
• Enable — Enables the device to establish a point-to-point link, or
specifies for the device to automatically establish a point-to-point
link. To establish communications over a point-to-point link, the
originating PPP first sends Link Control Protocol (LCP) packets
to configure and test the data link. After a link is established and
optional facilities are negotiated as needed by the LCP, the
originating PPP sends Network Control Protocols (NCP) packets
to select and configure one or more network layer protocols. 400 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
When each of the chosen network layer protocols has been
configured, packets from each network layer protocol can be sent
over the link. The link remains configured for communications
until explicit LCP or NCP packets close the link, or until some
external event occurs. This is the actual switch port link type. It
may differ from the administrative state.
• Disable — Disables point-to-point link.
• Auto — The device automatically establishes a point-to-point
link.
– Fast Link — Displays whether Fast Link mode is enabled for the port.
If this is enabled, the Port State is automatically placed in the
Forwarding statewhen the port is up.
– BPDU Guard — Displays whether BPDU Guard is enabled on the
port.
Miscellaneous fields:
– Policy Name — Displays the name of a policy if one is defined on the
port.
– Auto Negotiation — Displays whether auto-negotiation is enabled on
the port. Auto-Negotiation enables a port to advertise its transmission

Storm Control
When Broadcast, Multicast, or Unknown Unicast frames are received, they
are duplicated, and a copy is sent to all possible egress ports. This means that
in practice, they are sent to all ports belonging to the relevant VLAN. In this
way, one ingress frame is turned into many, creating the potential for a storm.
Storm protection provides the ability to limit the number of frames entering
the switch, and to define the types of frames that are counted towards this
limit.
When a threshold (limit) is configured on the device, the port discards traffic
when that threshold is reached. The port remains blocked until the traffic rate
drops below this threshold. It then resumes normal forwarding.

Port Mirroring
Switches usually only forward frames to relevant ports. To monitor traffic,
either for information gathering, such as statistical analysis, or for
troubleshooting higher-layer protocol operation, the Mirroring feature
forwards frames to a monitoring port.
Mirroring provides the ability to specify that a desired destination (target)
port will receive a copy of all traffic passing through designated source ports.
The frames arriving at the destination port are copies of the frames passing
through the source port at ingress, prior to any switch action.
It is possible to specify several source ports to be monitored by a single target
port. However, in this case, the traffic sent to the target port is placed in the
target port's queues on a first come, first served basis, and any excess traffic is
silently discarded. This may mean that the traffic actually seen by any device
attached to the target port is an arbitrarily selected subset of the actual traffic
going through the source ports.
Port mirroring is only relevant to physical ports. Therefore, if you want a LAG
to function as the source of a port mirroring session, the member ports must
be individually specified as sources.
Up to four sources can be mirrored. This can be any combination of four
individual ports.
Before configuring Port Mirroring, note the following:
• Monitored ports cannot operate faster than the monitoring port.
• All Rx/Tx packets should be monitored to the same port.
Destination Port Restrictions
The following restrictions apply to destination ports:
• Destination ports cannot be configured as source ports.
• Destination ports cannot be a member of a LAG.
• IP interfaces cannot be configured on the destination port.
• GVRP cannot be enabled on the destination port.
• The destination port cannot be a member of a VLAN.
• Only one destination port can be defined.418 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSwitching_Ports.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• All QoS/CoS rules that apply to the destination port, as an egress, such as
traffic shaping, are suspended for the duration of the mirroring session.
Any such settings, configured on the port during the mirroring session,
take effect only after the port is no longer a destination port for a
mirroring session.
• Ingress mirrored packets may arrive at the ingress port either with an
802.1q tag or without. When the packets are mirrored to a port analyzer,
they should be transmitted as they are received on the ingress port.
However, in the device, the packet is transmitted out of the port analyzer
as always tagged or always untagged (user configurable), regardless of the
input encapsulation.
Source Port Restrictions
The following restrictions apply to ports specified as source ports:
• Source ports cannot be a member of a LAG.
• Source ports cannot be configured as a destination port.
• Up to four source ports can be mirrored.
NOTE: When a port is set to be a target port for a port-mirroring session, all normal
operations on it are suspended. This includes Spanning Tree and LACP. All currently
active protocols and services on that port are suspended.Dell PowerConnect 55xx Systems User Guide 419

Overview
MAC addresses, associated with ports, are stored in the Static Address or the
Dynamic Address tables. Packets, addressed to a destination stored in one of
these tables, are forwarded to the associated port.
MAC addresses are dynamically learned when packets arrive at the device.
Addresses are associated with ports by learning the source address of the
frame. Frames, addressed to a destination MAC address that is not associated
with any port, are flooded to all ports of the relevant VLAN. In order to
prevent the bridging table from overflowing, dynamic MAC addresses, from
which no traffic is seen for a certain period, are erased.
Static addresses are manually entered into the table.424 Dell PowerConnect 55xx Systems User Guide

Dynamic Addresses
The Dynamic Address Table contains the MAC addresses acquired by
monitoring the source addresses of traffic entering the switch. When the
destination address for inbound traffic is found in the database, the packets
intended for that address are forwarded directly to the associated port.
Otherwise, the traffic is flooded to all ports in the VLAN of the frame.
To prevent the table from overflowing and to make room for new addresses,
an address is deleted from the table if no traffic is received from a dynamic
MAC address for a certain period. This period of time is called the aging
interval.

GARP Overview
Generic Attribute Registration Protocol (GARP) is a general-purpose protocol
that registers network connectivity or membership-style information. GARP
defines a set of devices interested in a given network attribute, such as VLAN
or Multicast address.
The Generic Attribute Registration Protocol (GARP) provides a generic
framework whereby devices in a bridged LAN, such as end stations and
switches, can register and de-register attribute values, such as VLAN
Identifiers, with each other. In doing so, these attributes are propagated to
devices in the bridged LAN, and these devices form a reachability tree that is
a subset of an active topology. GARP defines the architecture, rules of
operation, state machines and variables for the registration and deregistration
of attribute values.
When configuring GARP, ensure the following:
• The leave time must be greater than or equal to three times the join time.
• The leave-all time must be greater than the leave time.
• Set the same GARP timer values on all Layer 2-connected devices. If the
GARP timers are set differently on the Layer 2-connected devices, GARP
application does not operate successfully.432 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Spanning Tree Protocol Overview
Spanning Tree Protocol (STP) provides tree topography for any bridge
arrangement. STP eliminates loops by providing a unique path between end
stations on a network.
Loops occur when alternate routes exist between hosts. Loops, in an extended
network, can cause bridges to forward traffic indefinitely, resulting in packets
not arriving at their destination, increased traffic, and reduced network
efficiency.
The device supports the following Spanning Tree versions:
• Classic STP — Provides a single path between end stations, avoiding and
eliminating loops. For more information on configuring Classic STP, see
"Global Settings" on page 437.
• Rapid STP (RSTP) — Provides faster convergence of the spanning tree
than Classic STP. RSTP is most effective when the network topology is
naturally tree-structured, and therefore faster convergence might be
possible. RSTP is enabled by default.
Although Classic STP is guaranteed to prevent Layer 2 forwarding loops, in
a general network topology, there might be an unacceptable delay before
convergence. This means that before convergence, each bridge or switch in
the network must decide if it should actively forward traffic or not, on each
of its ports.
For more information on configuring Rapid STP, see "Rapid Spanning
Tree" on page 450.
• Multiple STP (MSTP) — MSTP is based on RSTP. It detects Layer 2
loops, and attempts to mitigate them by preventing the involved port from
transmitting traffic.
Since loops exist on a per-Layer 2-domain basis, a situation can occur
where there is a loop in VLAN A and no loop in VLAN B. If both VLANs
are on Port X, and STP wants to mitigate the loop, it stops traffic on the
entire port, including VLAN B traffic, where there is no need to stop
traffic.
Multiple Spanning Tree Protocol (MSTP) solves this problem by enabling
several STP instances, so that it is possible to detect and mitigate loops
separately in each instance. By associating instances to VLANs, each 436 Dell PowerConnect 55xx Systems User Guide

instance is associated with the Layer 2 domain on which it performs loop
detection and mitigation. This enables a port to be stopped in one
instance, such as traffic from VLAN A that is causing a loop, while traffic
can remain active in another domain where no loop was seen, such as on
VLAN B.
MSTP provides full connectivity for packets allocated to any VLAN, and
transmits packets assigned to various VLANs, through different multiple
spanning tree (MST) regions.
MST regions act as a single bridge.

Rapid Spanning Tree
While classic spanning tree prevents Layer 2 forwarding loops on a general
network topology, convergence can take from 30 to 60 seconds. This delay
provides time to detect possible loops, and propagate status changes.
Rapid Spanning Tree Protocol (RSTP) detects and uses network topologies
that enable a faster convergence of the spanning tree, without creating
forwarding loops.

established, or permits the device to establish a point-to-point link.
The possible options are:
• Enable — Enables the device to establish a point-to-point link, or
specifies for the device to automatically establish a point-to-point
link. To establish communications over a point-to-point link, the
originating PPP first sends Link Control Protocol (LCP) packets
to configure and test the data link. After a link is established and
optional facilities are negotiated as needed by the LCP, the
originating PPP sends Network Control Protocols (NCP) packets

test. This discovers whether the link partner using STP still exists, and
if so whether it has migrated to RSTP or MSTP. If it still exists as an
STP link, the device continues to communicate with it by using STP.
Otherwise, if it has been migrated to RSTP or MSTP, the device
communicates with it using RSTP or MSTP, respectively.

MSTP Overview
MSTP maps VLANs into STP instances, using various load balancing
scenarios. As a result of this partitioning into instances, if port A is blocked in
one STP instance, the same port can be placed in the Forwarding State in
another STP instance.
In addition, packets assigned to various VLANs are transmitted along
different paths within Multiple Spanning Trees Regions (MST Regions).
Regions are one or more Multiple Spanning Tree bridges by which frames can
be transmitted.

Virtual LAN Overview
A VLAN is a switched network that is logically segmented on an
organizational basis, by functions, project teams, or applications rather than
on a physical or geographical basis. For example, all workstations and servers
used by a particular workgroup team can be connected to the same VLAN,
regardless of their physical connections to the network, or the fact that they
might be intermingled with other teams. Reconfiguration of the network can
be done through software rather than by physically unplugging and moving
devices or wires.
A VLAN can be thought of as a Broadcast domain that exists within a defined
set of switches. A VLAN consists of a number of end systems, either hosts or
network equipment (such as bridges and routers), connected by a single
bridging domain. The bridging domain is supported on various pieces of
network equipment; for example, LAN switches that operate bridging
protocols between them with a separate bridge group for each VLAN.
VLANs are created to provide the segmentation services traditionally
provided by routers in LAN configurations. VLANs address scalability,
security, and network management. Routers in VLAN topologies provide
broadcast filtering, security, address summarization, and traffic flow
management.
None of the switches, within a defined group, will bridge any frames, not even
broadcast frames, between two VLANs. 468 Dell PowerConnect 55xx Systems User Guide

Frame Flow
Figure 14-1 describes the flow of VLAN frames from the Ingress port to the
Egress port:
Figure 14-1. Frame Flow Through a VLAN
When a frame is received, it must be assigned a VLAN. VLAN assignment is
accomplished by the following steps:
1 If the frame contains a VLAN tag, that tag is used, otherwise the frame is
classified by the port's default VLAN (PVID), if it is defined.
2 After classification, the frame may pass (if enabled) through ingress
filtering, where the frame is dropped if the frame's VLAN ID is not one of
the VLANs to which the ingress port belongs.
3 A forwarding decision is made, as a function of the VLAN ID and the
destination MAC address.
4 The egress rules define whether the frame is to be sent as tagged or
untagged.
Special-case VLANs
VLAN#1 and VLAN#4095 are special-case VLANs:
• VLAN1 — Defined as the default VLAN, and may only be used as a Ports
Default VLAN ID (PVID). This means that if the VLAN, whose VID is the
current port's PVID, is deleted from the port (or from the system), that
port's PVID is set to 1. VLAN#1 cannot be deleted from the system.
• VLAN #4095 — Defined (according to standard and industry practice) as
the "discard" VLAN. A frame classified to this VLAN is silently dropped.

QinQ Tagging
QinQ tagging enables you to add an additional tag to previously-tagged
packets. The added tag provides a VLAN ID to each customer, which ensures
private and segregated network traffic. The VLAN ID tag is assigned to a
customer port in the service provider network. The designated port then
provides additional services to the packets with the double-tags. This enables
administrators to expand service to VLAN users.
Port Modes
Ports participating in Layer 2 switching may be classified as:
• Access Ports
Ports set to Access mode belong to a single VLAN, whose VID is the
currently set PVID (default =1). These ports accept all untagged frames,
and all frames tagged with the VID, currently set as the port's PVID. All
traffic is sent untagged. If the VLAN, whose VID is set as the current PVID
of the port, is deleted from the system, or deleted from the port, the port's
PVID will be set to 1, meaning that the port will be made a member of
VLAN#1, the default VLAN.
Ingress filtering is always enabled for ports in Access mode.
Setting an Access port’s PVID to 4095 effectively shuts it down, as no
frames will be transferred in either direction.
Access mode ports are intended to connect end-stations to the system,
especially when the end-stations are incapable of generating VLAN tags.
• Trunk Ports
Ports set to Trunk mode may belong to multiple VLANs. The default
VLAN membership of a trunk port is all VLANs (1-4094). A PVID must be
set on the port (it can be a non-existing VLAN). Trunk ports accept tagged
and untagged frames. Untagged frames will be classified to the VLAN
whose VLAN ID (VID) is configured as the port’s PVID.
Frames, sent from the port in the VLAN, whose VID is the current PVID,
are sent untagged. Frames sent in all other VLANs active on the port are
sent tagged.470 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSwitching_VLAN.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Ingress filtering is always enabled on Trunk-mode ports. Incoming frames
will undergo ingress filtering, and if correctly tagged, (tagged with a VID of
one of the VLANs to which the port currently belongs) are admitted.
The default PVID is 1 (the default VLAN). If another VID is configured as
the port’s PVID, and the corresponding VLAN is deleted from the port or
from the system, the port’s PVID reverts to 1, meaning that the port is
made a member of the default VLAN.
Setting a trunk-port’s PVID to 4095 limits traffic to tagged frames.
Incoming untagged frames are silently discarded, and no frames are sent
untagged.
Trunk-mode ports are intended for switch-to-switch links, where traffic is
usually tagged.
• General Ports
Ports set to General mode may be members of multiple VLANs. Each of
these VLANs may be configured to be tagged or untagged. This setting
applies to transmitted frames. Incoming untagged frames are classified
into the VLAN whose VID is the currently configured PVID.
Ingress filtering may be disabled on General ports. Ingress filtering is
enabled by default.
• Promiscuous Ports
A promiscuous port can communicate with all ports of the same Private
VLAN (PVLAN), including the isolated ports of the same PVLAN.
• Isolated
An isolated port has complete Layer 2 isolation from the other ports within
the same PVLAN, but not from the promiscuous ports. Isolated ports can
communicate with promiscuous ports.
In the factory default configuration, all ports are designated as Access ports,
and are associated with the default VLAN.Dell PowerConnect 55xx Systems User Guide 471

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Acceptable Frame Type
The acceptable frame type can be set on a port to accept all frames (tagged
and untagged), tagged only, or untagged only. This setting takes precedence
over all other settings, so that if the acceptable frame type is tagged only,
incoming untagged frames are silently discarded, even if the port has a valid
PVID.472 Dell PowerConnect 55xx Systems User Guide

Protocol Groups
Protocol groups are based on protocol-based VLANs.
Protocol-based VLANs
Untagged frames received on a VLAN-aware switch can be classified by
methods others than source port, such as data-link-layer protocol
identification. This classification method is referred to as protocol-based
VLANs.
Protocol-based VLANs are useful for isolating Layer 2 traffic of various Layer
3 protocols. If, for example, a switch serves IP stations and IPX stations that
communicate with a single VLAN-unaware server, without using
protocol-based VLANs, all the Layer 2 Broadcast traffic would reach all the
stations. With protocol-based VLANs, the switch can forward incoming
traffic from the server to stations in a specific VLAN only.
Protocol-based VLANs are only available on General ports.
Classification rules are set on a per-port basis, and may be sensitive to the
frame's encapsulation. The default encapsulation assumed is Ethernet.
On each port, a user can define associations between groups of data-link layer
protocols and ports. For each group/port combination, the user may set the
VLAN to which frames incoming on that port will be classified if they belong
to any of the protocols in the group.
Several protocol-groups may be associated to a single port, and a protocol
group may be assigned to multiple ports, if so desired.
It is not guaranteed that the VLAN to which the frame is classified exists in
the system, or is active on that port.
Restrictions
The following frames (packet) types are supported: Ethernet, RFC 1042, and
LLC Other.
There may be dependencies between protocols and encapsulations, and
specifying one protocol may automatically add additional protocols to the

Similarly, there may be implied dependencies between encapsulations, so that
specifying an encapsulation implies defining the protocol group for related
encapsulations. An example of this is specifying the Ethernet encapsulation,
even by default, implies IEEE802 encapsulation, as per RFC 1042.
The following standards are relevant:
• IEEE802.1V defines VLAN assignment by protocol type.
• IETF RFC 10-2 defines a standard for the transmission of IP datagrams
over IEEE 802 Networks
Defining Protocol Groups
Define protocol groups in two steps:
1 Define a protocol group by assigning one or more protocols to the group
and giving it a protocol-group ID (any integer), using the Protocol Group
pages.
2 Associate the group with a desired VLAN classification, per port, using the
Protocol Port pages.486 Dell PowerConnect 55xx Systems User Guide

GVRP Parameters
GARP VLAN Registration Protocol (GVRP) is provided for automatic
distribution of VLAN membership information among VLAN-aware bridges.
GVRP enables VLAN-aware bridges to automatically learn VLANs-to-bridgeports mapping, without having to individually configure each bridge and
register VLAN membership.
To ensure the correct operation of the GVRP protocol, it is advised to set the
maximum number of GVRP VLANs equal to a value which significantly
exceeds:
– The number of all static VLANs both currently configured and
expected to be configured.
– The number of all dynamic VLANs participating in GVRP, both
currently configured (initial number of dynamic GVRP VLANs is 128)
and expected to be configured.
To set GVRP parameters:

Private VLAN
Private VLANs (PVLANs) provide Layer 2 isolation between ports that share
the same Broadcast domain, or in other words, they create a
point-to-multipoint Broadcast domain. The ports can be located anywhere in
the Layer 2 network, as opposed to protected ports which must be in the same
stack.
The switch ports can be members of a Private VLAN (PVLAN) in the
following membership types:
• Promiscuous ports that can communicate with all ports of the same
PVLAN, including the isolated ports of the same PVLAN.
• Isolated ports that have complete Layer 2-isolation from the other ports
within the same PVLAN, but not from the promiscuous ports. Isolated
ports can communicate with promiscuous ports.
The PVLAN entity is implemented by allocating the following VLANs per PVLAN:
• Primary VLAN: Carries traffic from promiscuous ports.
• Isolated VLAN: Carries traffic from isolated ports.Dell PowerConnect 55xx Systems User Guide 495

Voice VLAN
The Voice VLAN feature enables you to enhance VoIP service by configuring
ports to carry IP-voice traffic from IP phones on a specific VLAN. This VLAN
is configured with a QoS profile that ensures high voice quality.
Equipment, such as VOIP phones, transmits IP traffic with a pre-configured
Organizational Unique Identifier (OUI) prefix in the source MAC address.
This enables the switch to dynamically identify ports connected to the VoIP
equipment and automatically add these ports to the Voice VLAN.
IP phones use one of the following modes, both of which are supported by the
device:
• Use only tagged packets for all communications.
• Initially use untagged packets while retrieving the initial IP address
through DHCP. Then the phone uses the Voice VLAN and starts sending
tagged VoIP packets.
Non-VoIP traffic is dropped from the Voice VLAN when the device is in Auto
Voice VLAN secured mode.
The Voice VLAN feature also provides QoS actions to VoIP, ensuring that the
quality of voice does not deteriorate if the IP traffic is received unevenly.
To summarize, when Voice VLAN is enabled and configured, and VoIP
equipment is connected to one of the switch ports, the VoIP traffic triggers
the switch’s Voice VLAN feature to add this port to the Voice VLAN (a VLAN
that usually carries only voice traffic), and to assign traffic from this port a
specific QoS profile, ensuring high voice quality.
The device supports a single voice VLAN. Dell PowerConnect 55xx Systems User Guide 499

Link Aggregation Overview
Link Aggregation optimizes port usage by linking a group of ports together to
form a single LAG (aggregated group). Aggregating ports multiplies the
bandwidth between the devices, increases port flexibility, and provides link
redundancy.
The device supports the following types of LAGs:
• Static LAGs — Manually-configured LAGs.
• Link Aggregation Control Protocol (LACP) LAGs — LACP LAGs
negotiate aggregating a port’s links with other LACP ports located on a
different device. If the other device ports are also LACP ports, the devices
establishes a LAG between them.
When you aggregate ports, the ports and LAG must fulfill the following
conditions:
• All ports within a LAG must be the same media type.
• A VLAN is not configured on the port.
• The port is not assigned to another LAG.
• Auto-negotiation mode is not configured on the port.
• The port is in full-duplex mode.
• All ports in the LAG have the same ingress filtering and tagged modes.
• All ports in the LAG have the same back pressure and flow control modes.
• All ports in the LAG have the same priority.
• All ports in the LAG have the same transceiver type.
• The device supports up to 32 LAGs, and eight ports in each LAG.
• Ports can be configured as LACP ports only if the ports are not part of a
previously configured LAG.510 Dell PowerConnect 55xx Systems User Guide

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Ports added to a LAG lose their individual port configuration. When ports are
removed from the LAG, the original port configuration is applied to the ports.
The device uses a hash function to assign packets to a LAG member. The
hash function statistically load-balances the aggregated link members. The
device considers an Aggregated Link to be a single logical port.
Aggregate ports can be linked into link-aggregation port-groups. Each group
comprises ports with the same speed, set to full-duplex operations.
Ports in a LAG can contain different media types if the ports are operating at
the same speed. Aggregated links can be manually or automatically
configured by enabling LACP on the relevant links.Dell PowerConnect 55xx Systems User Guide 511

LACP Parameters
To define LACP LAGs, configure LACP global and port parameters, such as
LACP system priority, timeout, and port priority.
With all factors equal, when the LAG is configured with more candidate ports
than the maximum number of active ports allowed, the switch activates the
highest priority candidate ports from the dynamic LAG.

LAG Membership
Each device supports up to 32 LAGs per system, and eight ports per LAG.
When you add a port to a LAG, the port acquires the LAG’s properties. If the
port cannot be configured with the LAG’s properties, it is not added to the
LAG and an error message is generated.
If the first port joining the LAG cannot be configured with the LAG settings,
the port is added to the LAG, using the port default settings, and an error
message is generated. Since this is the only port in the LAG, the entire LAG
operates with the port’s settings, instead of the LAG’s defined settings.
To assign ports to LAGs:

Multicast Support Overview
Multicast forwarding enables a single packet to be forwarded to multiple
destinations. Layer 2 Multicast service is based on a Layer 2 device receiving a
single packet addressed to a specific Multicast address. Multicast forwarding
creates copies of the packet, and transmits the packets to the relevant ports.
There are two types of Multicast groups:
• Registered Multicast Group — When traffic addressed to a registered
Multicast group is received, it is handled according to its entry in the
Multicast Filtering Database and forwarded only to the registered
ports.
• Unregistered Multicast Group — If traffic addressed to an
unregistered Multicast group is received, it is handled by a special
entry in the Multicast Filtering Database. The default setting of this is
to flood all such traffic (traffic in unregistered Multicast groups).
The device supports:
• Forwarding L2 Multicast Packets — Forwards Layer 2 Multicast
packets. Layer 2 Multicast filtering is enabled by default, and is not
user-configurable.
• Filtering L2 Multicast Packets — Forwards Layer 2 packets to
interfaces. If Multicast filtering is disabled, Multicast packets are
flooded to all relevant ports.
NOTE: The system supports Multicast filtering for 256 Multicast groups.
Layer 2 Switching
Layer 2 switching forwards Multicast packets to all relevant VLAN ports by
default, managing the packet as a single Multicast transmission. While
Multicast traffic forwarding is effective, it is not optimal, as irrelevant ports
also receive the Multicast packets. The excess packets cause increased
network traffic. Multicast forwarding filters enable forwarding of Layer 2
packets to a subset of ports instead of to all ports.518 Dell PowerConnect 55xx Systems User Guide

IGMP
Internet Group Multicast Protocol (IGMP) adds IGMP packets to Multicast
traffic. When IGMP Snooping is enabled globally, all IGMP packets are
forwarded to the CPU. The CPU analyzes the incoming packets and
determines:
• Which ports want to join which Multicast groups.
• Which ports have Multicast routers generating IGMP queries.
• What routing protocols are forwarding packets and Multicast traffic.
Ports requesting to join a specific Multicast group issue an IGMP report,
specifying that the Multicast group is accepting members. This results in the
creation of an entry in the Multicast filtering database. Dell PowerConnect 55xx Systems User Guide 519

IGMP Snooping
IGMP Snooping can be enabled globally, as described in the Global
Parameters page. It can also be enabled per VLAN to support selective IPv4
Multicast forwarding. In this case, Bridge Multicast filtering must also be
enabled.
By default, a Layer 2 switch forwards Multicast frames to all ports of the
relevant VLAN, essentially treating the frame as if it were a Broadcast. When
IGMP Snooping is enabled per VLAN, the switch forwards Multicast frames
to ports that have registered as Multicast clients in the VLAN.
NOTE: The switch supports IGMP Snooping only on static VLANs. It does not
support IGMP Snooping on dynamic VLANs.528 Dell PowerConnect 55xx Systems User Guide

The IGMP Snooping Querier is used to support a Layer 2 Multicast domain
of snooping switches in the absence of a Multicast router, for example, where
Multicast content is provided by a local server, but the router (if one exists)
on that network does not support Multicast.
There should only be a single IGMP Querier in a Layer 2 Multicast domain.
The switch supports standards-based IGMP Querier election when more than
one IGMP Querier is present in the domain.
The speed of IGMP Querier activity should be aligned with the IGMPsnooping-enabled switches. Queries should be sent at a rate that is aligned to
the snooping table aging time. If queries are sent at a rate lower than the
aging time, the subscriber cannot receive the Multicast packets.

Unregistered Multicast
Multicast frames are generally forwarded to all ports in the VLAN. If IGMP
Snooping is enabled, the device learns about the existence of Multicast
groups and tracks which ports have joined what Multicast group.
Multicast groups can also be statically enabled. This enables the device to
forward the Multicast frames (from a registered Multicast group) only to
ports that are registered to that Multicast group.
Traffic from unregistered Multicast groups, which are the groups that are not
known to the device, can either be filtered or forwarded. After a port has been
set to Forwarding/Filtering, its configuration is valid for any VLAN of which it
is a member (or will be a member of).
To set the action for unregistered Multicast groups on a port:

Multicast TV VLAN
This section describes the Multicast TV VLAN feature.
It contains the following sections:
• Multicast TV VLAN Overview
• Multicast TV VLAN Membership
• Multicast TV VLAN Mapping
Multicast TV VLAN Overview
The Multicast TV VLAN feature provides the ability to supply Multicast
transmissions to Layer 2-isolated subscribers, without replicating the
Multicast transmissions for all subscriber VLANs. The subscribers are the
only receivers of the Multicast transmissions.
• A Multicast TV VLAN can be defined for an Access port (a port that is
in Access mode for VLAN membership).
• All static VLANs are permitted to be a Multicast-TV VLAN.
• The configuration is performed per port.
One or more IP Multicast address groups can be associated with a Multicast
VLAN. The source port must belong to the Multicast VLAN. Source and
receiver ports do not have to be members of the same VLAN.
An end port is defined as a receiver port for the Multicast VLAN. Receiving
ports can belong to a single user VLAN and additionally to one Multicast
VLAN. The receiver port can be an access member in any VLAN, but not in
the defined Multicast VLAN. In Multicast VLAN, the receiver port can only
receive traffic and not send traffic on it. Receivers of same Multicast VLAN
are isolated in different User (Access port) VLANs and therefore isolated from
each other.
If a Multicast-TV VLAN is defined on an access port, then:
• The access port joins the Multicast-TV VLAN.

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
LLDP Overview
The Link Layer Discovery Protocol (LLDP) enables network managers to
troubleshoot and enhance network management by discovering and
maintaining network topologies over multi-vendor environments. LLDP
discovers network neighbors by standardizing methods for network devices to
advertise themselves to other systems, and to store discovered information.
Discovery information includes:
• Device identification
• Device capabilities
• Device configuration
The advertising device transmits multiple advertisement message sets in a
single LAN packet. The multiple advertisement message sets are sent in the
packet’s Type Length Value (TLV) field.
LLDP devices must support chassis and port ID advertisements, as well as
system name, system ID, system description, and system capability
advertisements.
LLDP Media Endpoint Discovery (LLDP-MED) increases network flexibility
by enabling various IP systems to co-exist on a single network, and provides
the following features:
• Detailed network topology information, including information on which
devices are located on the network and where the devices are located, for
example, which IP phone is connect to which port, which software is
running on which switch, and which port is connected to which device.
• Automatic deployment of policies over networks for:
– QoS Policies
– Voice VLANs
• Emergency Call Service (E-911) via IP phone location information.
• Troubleshooting information. LLDP MED sends network managers alerts
for:
– Port speed and duplex mode conflicts
– QoS policy misconfigurations542 Dell PowerConnect 55xx Systems User Guide

LLDP Port Settings
LLDP configuration of a port includes activating LLDP notification on it,
and selecting the optional TLVs that will be sent in the LLDP PDU, in
addition to the mandatory ones.
By setting these properties, it is possible to provide additional types of
information to those network devices that support the LLDP.
To configure LLDP per port:

MED Network Policy
An LLDP-MED network policy is a set of configuration settings that is
identified by a network policy number. Policies are loaded into LLDP-MED
TLVs, and sent to devices connected to the switch. A network policy instructs
the connected device as to how to send traffic, for example, a policy can be
created for VoIP phones that instructs them to:
• Send voice traffic on VLAN 10
• Tag voice traffic with DSCP=63
• Transmit data-traffic to the switch (from the PC connected to the switch
through the VoIP phone) without modification to traffic sent by the PC
(typically, Untagged).
For network policies to be implemented, they must be created and then
associated with ports.
Before policies are defined, the administrator must create the VLANs, and
configure memberships in the VLANs, based on the specification in the
LLDP-MED network policies. 550 Dell PowerConnect 55xx Systems User Guide

Dynamic ARP Inspection Overview
ARP Inspection eliminates man-in-the-middle attacks, where false ARP
packets are inserted into the subnet. ARP requests and responses are
inspected, and their MAC-address-to-IP-address binding is checked according
to the ARP Inspection List defined by the user (in the Dynamic ARP
Inspection List and Dynamic ARP Inspection Entries pages). If the packet’s IP
address was not found in the ARP Inspection List, and DHCP Snooping is
enabled for a VLAN, a search of the DHCP Snooping database is performed.
See "How DHCP Snooping Works" on page 573 for an explanation of the
DHCP Snooping database. If the IP address is found the packet is valid, and is
forwarded.
Packets with invalid ARP Inspection bindings are logged and dropped.
Ports are classified as follows:
• Trusted — Packets are not inspected.
• Untrusted —Packets are inspected as described above.
The following additional validation checks may be configured by the user:
• Source MAC — Compares the packet’s source MAC address in the
Ethernet header against the sender’s MAC address in the ARP request.
This check is performed on both ARP requests and responses.
• Destination MAC — Compares the packet’s destination MAC address in
the Ethernet header against the destination interface’s MAC address. This
check is performed for ARP responses.
• IP Addresses — Compares the ARP body for invalid and unexpected IP
addresses. Addresses include 0.0.0.0, 255.255.255.255, and all IP Multicast
addresses. 562 Dell PowerConnect 55xx Systems User Guide

DHCP Snooping
This section describes DHCP snooping.
It contains the following topics:
• DHCP Snooping Overview
• Global Parameters
• VLAN Settings
• Trusted Interfaces
• Snooping Binding Database
DHCP Snooping Overview
DHCP snooping expands network security by providing layer security
between untrusted interfaces and DHCP servers. By enabling DHCP
snooping, network administrators can differentiate between trusted interfaces
connected to end-users or DHCP Servers, and untrusted interfaces located
beyond the network firewall.
How DHCP Snooping Works
DHCP snooping filters untrusted messages, and stores these messages in a
database. Interfaces are untrusted if the packet is received from an interface
outside the network, or from an interface beyond the network firewall.
Trusted interfaces receive packets only from within the network or the
network firewall.
The DHCP Snooping Binding database contains the untrusted interfaces’
MAC address, IP address, Lease Time, VLAN ID, and interface information.
Table 19-1 describes how DHCP packets are handled when DHCP snooping
is enabled on an interface.

As shown in Table 19-1, the DHCP Snooping Binding database is updated by
interception of DHCPACK, DHCPDECLINE and DHCPRELEASE packets,
and is stored in non-volatile memory.
Even if a port is down, its entries are not deleted.
NOTE: Only DHCP requests on untrusted ports are maintained in the Binding
database.
Limitations
The following limitations apply:
• Enabling DHCP snooping uses TCAM resources.
• The switch writes changes to the binding database only when the switch
system clock is synchronized with SNTP.
• The switch does not update the Binding database when a station moves to
another interface.
Global Parameters
Use the Global Parameters page to:
• Enable/disable DHCP snooping globally.
• Determine whether to forward or filter DHCP packets received from
untrusted interfaces, whose source MAC address and the DHCP client
MAC address do not match.
• Determine whether to forward or filter DHCP packets, received from
untrusted interfaces, with option-82 information.

DHCP Relay
This section describes DHCP relay.
It contains the following topics:
• DHCP Relay Overview
• Option 82
• Global Settings
• Interface Settings
DHCP Relay Overview
The device can act as a DHCP Relay agent that listens for DHCP messages,
and relays them between DHCP servers and clients, which reside in different
VLANs or IP subnets.
This functionality is intended to be used when the client ingress VLAN is
different than the VLAN on which DHCP servers are connected.
The switch can relay DHCP messages received from its IPv4 interfaces to one
or more configured DHCP servers. The switch puts the IPv4 address into the
message giaddr before relaying it to the servers. It uses the switch’s IPv4
address of the interface where the message is received. The switch uses the
giaddr from the response to determine how to forward the response back to
the DHCP client.
DHCP Relay must be enabled globally and per VLAN. Dell PowerConnect 55xx Systems User Guide 587
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSwitching_DHCP.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Option 82 Overview
The relay agent information option (Option 82) in the DHCP protocol
enables a DHCP relay agent to send additional client information when
requesting an IP address. Option 82 specifies the relaying switch's MAC
address, the port identifier, and the VLAN that forwarded the packet.
Both DHCP snooping and DHCP relay can insert option 82 into traversing
packets.
DHCP snooping with option 82 insertion provides transparent Layer 2 relay
agent functionality when the DHCP server is on the same VLAN as the
clients.
Limitations
The following limitations exist for DHCP Relay:
• It is not supported on IPv6.
• It is not relayed to servers on the client’s VLAN.
• Packets that have option-82 information, added by other devices, are
discarded.
• It does not support Option 82 on non-VLAN interfaces.
• It can be enabled only on a VLAN/Port/LAG that has an IP address defined
on it.588 Dell PowerConnect 55xx Systems User Guide

Optimizing iSCSI Overview
The Internet Small Computer System Interface (iSCSI) is an IP-based
storage networking standard for linking data storage facilities. By carrying
SCSI commands over IP networks, iSCSI is used to facilitate data transfers
over intranets, and to manage storage over long distances.
iSCSI can be used to transmit data over local area networks (LANs), wide area
networks (WANs), or the Internet, and can enable location-independent data
storage and retrieval.
Unlike traditional Fiber channels, which requires special-purpose cabling,
iSCSI can be run over long distances, using existing network infrastructure.
The protocol enables clients (called initiators) to send SCSI commands
(CDBs) to SCSI storage devices (targets) on remote servers. This enables
organizations to consolidate storage into data center storage arrays, while
providing hosts (such as database and web servers) with the illusion of
locally-attached disks.
The targets listen on a well-known TCP port (or any other TCP port that has
been explicitly specified) for incoming connections. The login process is
started when the initiator establishes a TCP connection to the desired target,
through the TCP port that was explicitly specified.
The group of iSCSI TCP connections that link an initiator with a target is
called an iSCSI session.
When you connect an EqualLogic device to the switch, and iSCSI
optimization is enabled, the switch automatically recognizes the port to
which the EqualLogic equipment is connected to, and configures the STP
Mode to RSTP to support fast network convergence.
Optimizing iSCSI
iSCSI optimization provides the following features:
• Ability to assign a specific QoS profile to the iSCSI flows
• Display of iSCSI session details (connections, initiator, target, and so on)
• Identification of (self-discovered) iSCSI sessions
• Identification of iSCSI session termination
• Identification of non-active iSCSI sessions596 Dell PowerConnect 55xx Systems User Guide

Limitations
The following limitations exist:
• All iSCSI connections receive the relevant QoS, regardless of whether they
are being monitored or not. If, for example, a feature was disabled for some
period and was enabled again, it is possible that there are iSCSI TCP
connections that were established during this period of time. These cannot
be monitored, because all relevant information was already passed at the
beginning of the session. But these unidentified sessions will still be
assigned to iSCSI QoS.
• The maximum number of iSCSI TCP connections, which is also the
default setting, is 1K. This can be changed after reset.
• The number of iSCSI connections affects other system features.
iSCSI-aware, DHCP Snooping, and ACL rules all use the TCAM system
resource. If the number of iSCSI connections has been increased, the
other application rules (DHCP Snooping or ACL) can be removed after
reset.
• If the target uses redirect messages upon the initiator request, and, as a
result, the initiator opens a connection to a different target, the new target
must be configured as part of the general configuration.
• Only iSCSI flows to targets that use the iSCSI well-known port or other
explicit user-defined configuration are assigned QoS.
• The aging configuration works for each connection. The mechanism
checks connection activities in a group of 28 TCP iSCSI connections,
within the aging time. In the worst case, when the maximum number of
1K TCP connections are monitored and are not terminated gracefully, the
mechanism causes inaccuracy, namely, the last 28 TCP iSCSI connections
are aged out after (1K/28)*aging-time.
• In general, the greater the number of ungracefully terminated iSCSI TCP
connections, the greater the inaccuracy is. Not all iSCSI TCP connections
are monitored for aging at the same time. Sessions, whose associated TCP
connections are not being currently monitored, will show unchanged aging
time.
• Encryption (Ipsec) must not be applied on iSCSI traffic, otherwise a QoS
profile will not be assigned to iSCSI.
• iSCSI optimization does not work with IP fragmented frames.Dell PowerConnect 55xx Systems User Guide 597
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGSwitching_iscsi.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
• Each session supports at most four TCP connections. If a new TCP
connection of an already opened iSCSI session arrives, and there are
already four TCP connections, the new connection replaces the oldest one,
within this specific iSCSI session.
• A short flow interruption, caused by STP topology change or
administrative port-down action, might cause the TCP connection to
reinitiate without closing the iSCSI session. If the actual iSCSI session
used only one TCP connection, the reinitiated one will be added to the
monitoring table, for an aging-time period. After that, it is removed from
the list.598 Dell PowerConnect 55xx Systems User Guide

Global Parameters
Use the Global Parameters page to enable iSCSI and to set iSCSI QoS frame
priority. You may also enable Remark to change the DSCP or CoS user
priority field in the packet. In the QoS Properties pages, you can then set the
queuing to strict priority or WRR, and map the CoS or DSCP to the desired
queue in the CoS to Queue or DSCP to Queue pages.
To enable iSCSI and set its QoS parameters:
1 Click System > iSCSI Optimization > Global Parameters in the tree
view to display the Global Parameters page.
Figure 20-1. Global Parameters
2 Enter the fields:
– iSCSI Status — Enable/disable iSCSI optimization.
– iSCSI COS Status — Enable/disable the Class of Service profile to
apply to iSCSI flows.
– Classification — Select whether the priority of iSCSI packets is
determined by CoS or DSCP. Check the classification, and select the
desired value.
– Remark — Enable/disable whether iSCSI frames will be remarked
with the CoS or DSCP value.Dell PowerConnect 55xx Systems User Guide 599

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
– iSCSI Aging Time — Enter how long the device will wait, after the
last received frame of an iSCSI session, before deleting the session
from the list.
Enabling iSCSI automatically enables Jumbo frames and enables Flow
Control on all interfaces. Jumbo frames are only enabled after copying the
Running configuration to the Startup configuration and resetting the device
(the Flow Control changes are effective immediately).

The QoS feature is used to optimize network performance. It provides
classification of incoming traffic into traffic classes, based on one or more
attributes, including:
– Device configuration
– Ingress interface
– Packet contents
QoS includes the following features:
• Traffic Classification — Classifies each incoming packet, as belonging to
a specific traffic flow, based on the packet contents and/or interface. The
classification is done by an ACL (Access Control List), and only traffic
that meets the ACL criteria is subject to classification.
• Assignment to Hardware Queues — Assigns incoming packets to
forwarding queues. Packets are sent to a particular queue for handling as a
function of the traffic class to which they belong.
• Other Traffic Class-Handling Attribute — Applies QoS mechanisms to
various classes, including bandwidth management.
QoS Modes
A single QoS mode is selected and applies to all interfaces in the system. The
modes are:
• Basic Mode — Class of Service (CoS).
– Traffic is divided into classes that determine how it is treated. All
traffic in a class is treated with the same QoS action. The QoS action
for the class of traffic determines the egress queue on the egress port,
based on the indicated QoS value in the incoming frame.
The QoS value in the incoming frame is:
• Layer 2 Packets — VLAN Priority Tag (VPT) 802.1p value
• Layer 3 IPv4 Frames — Differentiated Service Code Point
(DSCP) value
• Layer 3 IPv6 Frames —Traffic Class (TC) value
When operating in Basic mode, the switch trusts this
externally-assigned QoS value. 652 Dell PowerConnect 55xx Systems User Guide
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Contax\sources\CxUGQoS.fm
DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
This is the default QoS mode.
• Advanced Mode — Per-flow Quality of Service (QoS).
In Advanced mode, a per-flow QoS consists of a class map and a policer:
– A class map defines the kind of traffic in a flow, and contains one or
more ACLs. Packets that match the ACLs belong to the flow.
– A policer applies the configured QoS to a flow. The QoS configuration
of a flow may consist of the egress queue, the DSCP or CoS value, and
actions on out-of-profile (excess) traffic.
• Disable Mode (QoS is not enabled)
In this mode, all traffic is mapped to a single best-effort queue, so that no
type of traffic is prioritized over another.
Only a single mode can be active at a time. When the system is configured to
work in QoS Advanced mode, settings for QoS Basic mode are not active and
vice versa.
When the QoS mode is changed, the following occurs:
• When changing from Advanced mode to any other mode, policy profile
definitions and class maps are deleted. ACLs, which are bonded directly to
interfaces, remain bonded.
• When changing from Basic mode to Advanced mode, the QoS Trust mode
configuration in Basic mode is not retained.
• When disabling QoS, the shaper and queue setting (WRR/SP bandwidth
settings) are reset to default values.
All other user configurations remain intact.Dell PowerConnect 55xx Systems User Guide 653

Configuring QoS Properties Using CLI Commands
The following table summarizes the CLI commands for configuring fields in
the QoS Properties: Summary page.
The following is an example of the CLI command:
Queue
The switch supports eight queues for each interface. Queue number eight is
the highest priority queue. Queue number one is the lowest priority queue.
Traffic Limitation Methods
There are two ways of determining how traffic in queues is handled, Strict
Priority and Weighted Round Robin (WRR):
• Strict Priority — Egress traffic from the highest-priority queue is
transmitted first. Traffic from the lower queues is processed only after the
highest queue has been transmitted, thus providing the highest level of
priority of traffic to the lowest-numbered queue.
• Weighted Round Robin (WRR) — In WRR mode, the number of packets
sent from the queue is proportional to the weight of the queue (the higher
the weight, the more frames are sent). For example, if all eight queues are
WRR and the default weights are used, queue 1 receives 1/15 of the
bandwidth (assuming all queues are saturated and there is congestion),
queue 2 receives 2/15, queue 3 receives 4/15, and queue 8 receives 8/15 of
the bandwidth. The type of WRR algorithm used in the device is not the
standard Deficit WRR (DWRR), but rather Shaped Deficit WRR
(SDWRR).

DELL CONFIDENTIAL – PRELIMINARY 3/11/13 - FOR PROOF ONLY
Combination of WRR and Strict Priority
The priority for handling traffic can be selected for each queue. When the
queuing mode is Weighted Round Robin for all queues, queues are serviced
according to their weights. If all queues are assigned strict priority, queues are
serviced according to that order.
The following is true if some queues are assigned strict priority and others are
assigned WRR:
• If one queue is assigned strict priority, all higher queues are also assigned
strict priority. Conversely, if a queue is assigned a WRR weight, all lower
queues must also have a WRR weight assigned to them.
• In the above case, traffic for the strict priority queues is always sent before
traffic from the WRR queues. Traffic from the WRR queues is forwarded
only after the strict priority queues have been emptied. The relative
portion from each WRR queue depends on its weight.658 Dell PowerConnect 55xx Systems User Guide

QoS Basic Mode
This section describes QoS Basic mode.
It contains the following topics:
• Basic Mode Overview
• Workflow to Configure Basic Mode
• Global Settings
• DSCP Rewrite
• Interface Settings
Basic Mode Overview
In QoS Basic mode, a specific domain in the network can be defined as
trusted. Within that domain, packets are marked with CoS priority and/or
DSCP values, to signal the type of service they require. Nodes within the
domain use these fields to assign the packet to a specific output queue. The
initial packet classification and marking of these fields is done in the ingress
of the trusted domain.
Workflow to Configure Basic Mode
To configure Basic QoS mode, perform the following:
1 Select Basic mode for the system in the QoS Mode page.
2 Select the trust-behavior in the Global Settings page.
3 If there is any port that, as an exception, should not trust the incoming
CoS mark, disable the QoS state on that port in the Interface Settings
pages.
If a port is disabled without trusted mode, all its ingress packets are
forwarded in best effort. It is recommended that you disable the trusted
mode at the ports where the CoS and/or DSCP values in the incoming
packets are not trustworthy. Otherwise, performance in the network might
be negatively affected.
4 If you selected DSCP Rewrite in the Global Settings page, set the DSCP
in/out values in the DSCP Rewrite page.670 Dell PowerConnect 55xx Systems User Guide

• CoS — Traffic is mapped to queues, based on the VPT field in the
VLAN tag, or based on the per-port default CoS value (if there is
no VLAN tag on the incoming packet). The mapping of the VPT
to queue can be configured in the CoS to Queue page.
• DSCP — All IP traffic is mapped to queues, based on the DSCP
field in the IP header. The mapping of the DSCP to queue is
configured in the DSCP to Queue page.
– Always Rewrite DSCP — Check to always rewrite the DSCP values in
the incoming packets with the new values set in the DSCP to Queue

DSCP Rewrite
Use the DSCP Rewrite page to rewrite the DSCP tags for incoming traffic,
when different DSCP values are used in the incoming and outgoing domains.
Changing the DSCP value used in one domain to the DSCP value used in the
other domain preserves the priority of traffic used in the first domain.
As an example, assume that there are three levels of service: Silver, Gold, and
Platinum. The DSCP incoming values used to mark these levels are 10, 20,
and 30 respectively. If this traffic is forwarded to another service provider that
has the same three levels of service, but uses DSCP values 16, 24, and 48, the
values set in the DSCP Rewrite page are used to change the incoming values
to the outgoing values.

QoS Advanced Mode
This section describes QoS Advanced mode.
It contains the following topics:
• Advanced Mode Overview
• Workflow to Configure Advanced QoS Mode
• DSCP Mapping
• Class Mapping
• QoS Policers
• Policy Binding
Advanced Mode Overview
In Advanced mode, the switch uses policies to support per-flow QoS. A policy
and its components have the following characteristics and relationships:
• A policy contains one or more class maps.
• A class map defines a flow with one or more associated ACLs. Packets that
match the ACL rules (ACEs) in a class map with Permit (forward) action,
belong to the same flow, and are subject to the same quality of service
action. A policy can contain one or more flows, each with a user-defined
QoS action.
• The QoS of a class map (flow) may be enforced by the associated policer.
There are two type of policers, as described in "Defining Class Mapping
Using CLI Commands" on page 684.
• Per-flow QoS actions are applied to flows by binding the policy maps to the
desired ports. A policy map and its class maps can be bound to one or more
ports, but each port is bound with, at the most, one policy map.
The following points should be considered:
• An ACL can be configured to one or more class maps, regardless of
policies.
• A class map can belong to only one policy map.
• When a class map, using a single policer, is bound to multiple ports, each
port has its own instance of the policer. Each instance applies the QoS
actions on the class map (flow) at a port independent of each other.Dell PowerConnect 55xx Systems User Guide 679

• If you bind a policy map to more than one port and one of its classes
contains a single policer, all policy map rules will be multiplied per port
(using up more TCAM resources).
• An aggregate policer applies the QoS to all of its flows in aggregation,
regardless of policies and ports.
Advanced QoS settings consist of the following elements:
• Rules — All frames matching a single group of rules are considered to be a
flow.
• Actions — To be applied to frames in each flow that match the rules.
– Policers — See "Single Policers" on page 689
– Aggregate Policers — "Aggregate Policers" on page 687
– Trust —"Interface Settings" on page 674, "Policy Class Maps" on
page 692
– Set DSCP/CoS — "Policy Class Maps" on page 692
– Set Queue — "DSCP Mapping" on page 680
• Binding — Combination of rules and actions that are bound to one or
more interfaces.
Workflow to Configure Advanced QoS Mode
To configure Advanced QoS mode, perform the following:
1 Select Advanced mode for the system in the QoS Mode page.
2 If external DSCP values are different from those used on incoming
packets, map the external values to internal values in the DSCP Rewrite
page.
3 Create ACLs, as described in "Network Security" on page 97.
4 When ACLs are defined, create class maps and associate the ACLs with
them in the Class Mapping pages.
5 Create a policy map in the Policy Class Maps pages, and associate the
policy map with one or more class maps. Specify the QoS action, if needed,
for example by assigning a policer to a class map, when you associate the
class map to the policy.680 Dell PowerConnect 55xx Systems User Guide

a Single Policer — Create a policy that associates a class map with a
single policer in the Policy Table pages and the Class Mapping pages.
Within the policy, define the single policer.
b Aggregate Policer — Create a QoS action for each flow. This action
sends all matching frames to the same policer (aggregate policer),
defined in the Aggregate Policer pages. Create a policy that associates
a class map with the aggregate policer in the Policy Table pages.
6 Bind the policy to an interface in the Policy Binding pages.
DSCP Mapping
When a policer is assigned to a class map (flow), you can specify the action to
take when the amount of traffic in the flow(s) exceeds the QoS-specified
limits. The portion of the traffic that causes the flow to exceed its QoS limit
is referred to as out-of-profile packets.
If the exceed action is Remark DSCP (as opposed to Drop), the switch
rewrites the original DSCP value of the out-of-profile IP packets to a new
value, based on the values entered in the DSCP Mapping page. The switch
uses the new values to assign resources and egress queues to these packets.
The switch physically replaces the original DSCP value in the out-of-profile
packets with the new DSCP value.
To use the Remark DSCP exceed action, set the DSCP Out value in the
DSCP Mapping page. Otherwise the action is null, because the DSCP value
in the packet is rewritten to the original DSCP value, set by factory default.Dell PowerConnect 55xx Systems User Guide 681

Configuring DSCP Mapping Using CLI Commands
The following table summarizes the CLI commands for setting the fields in
the DSCP Mapping page.
The following is an example of the CLI commands:
Class Mapping
A Class Map defines a traffic flow associated with ACL(s). A MAC-based
ACL, IP-based ACL, and an IPv6-based ACL can be combined into a class
map. Class maps are configured to match packet criteria on a match-all or
match-any basis. They are matched to packets on a first-fit basis, meaning
that the action associated with the first-matched class map is the action
performed by the system. Packets that match the same class map belong to
the same flow.
There are two possible types of matching:
• match-all — Traffic matches class map if it matches IP/IPV6 and MAC
ACLs
• match-any — Traffic matches class map if it matches at least one of the
ACLs
If a more complex set of rules is needed, several class maps can be grouped
into a super-group called a policy (see "Defining Class Mapping Using CLI
Commands" on page 684).

QoS Policers Overview
The rate of traffic that matches a pre-defined set of rules can be measured,
and limits, such as limiting the rate of file-transfer traffic that is allowed on a
port, can be enforced.
This is done by using the ACLs in the class map(s) to match the desired
pattern of traffic, and by using a policer to apply QoS on the matching traffic.
A policer is configured with a QoS specification. There are two kinds of
policers:
• Single Policer — A single policer applies the QoS to a single class map,
and to a single flow, based on the policer's QoS specification. When a class
map, using a single policer, is bound to multiple ports, each port has its
own instance of the single policer; each applying the QoS on the class map
(flow) at ports that are otherwise independent of each other. A single
policer is created in the Policy Table and Policy Class Maps pages.
• Aggregate Policer — An aggregate policer applies QoS to one or more class
maps, and to one or more flows. An aggregation policer can support class
maps from various policies. An aggregate policer applies QoS to all its
flow(s) in aggregation, regardless of policies and ports. An aggregate policer
is created in the Aggregate Policer pages.
An aggregate policer is defined if the policer is to be shared with more than
one class.
Each policer is defined with its own QoS specification, and is composed of a
combination of the following parameters:
• Committed Information Rate (CIR) — A maximum allowed rate of
traffic, measured in Kbps.
• Committed Burst Size (CBS) — An amount of traffic, measured in bytes,
which is allowed to pass as a temporary burst, even if it is above the
defined maximum rate.
• Exceed Action — An action to be applied to frames that are over the limits
(called out-of-profile traffic). These frames can be forwarded as is,
dropped, or forwarded, after rewriting their DSCP value with a value that
marks them as lower-priority frames for all subsequent handling within the
device.
A policer is assigned to a class map when a class map is added to a policy.Dell PowerConnect 55xx Systems User Guide 687

Policy Binding
After policies are created, they must be bound to interfaces (ports or
LAGs).When a policy is bound to a specific interface, it becomes active on it
(subject to time range restrictions). Only one policy can be active on a single
interface, but a single policy can be bound to more than one interface.
When a policy is bound to an interface, it filters and applies QoS to ingress
traffic that belongs to the flows defined in the policy. The policy does not
apply to traffic egress to the same port.
To edit a policy, it must first be removed (unbound) from all those ports to
which it is bound.

Installation
Overview
This guide describes how to install and run the PowerConnect 5500 series
switches. For more information, see the Dell PowerConnect 5500 Series User
Guide, available on your Documentation CD, or check the Dell Support
website at support.dell.com/manuals for the latest updates on documentation
and software.
In this document, the word "switch" refers to either a single switch or a group
of stacked switches.
For a complete description of the PowerConnect 5500 series switch, see the
Dell PowerConnect 5500 Series User Guide, available on your Documentation
CD.
NOTE: Even though the graphics in this guide show the Dell PowerConnect 5524P
device, the instructions are the same for all models.
Site Preparation
PowerConnect 5500 series switches can be mounted in a standard 48.26-cm
(19-inch) equipment rack or placed on a tabletop. Before installing the unit,
verify that the chosen location for installation meets the following site
requirements:
• Power —
– The unit is installed near an easily accessible 100-240 VAC, 50-60 Hz
outlet.
– If a Redundant Power Supply (RPS) or a Modular Power Supply
(MPS) is being used, check that it is easily accessible.
• Clearance — There is adequate frontal clearance for operator access.
Allow clearance for cabling, power connections, and ventilation.
ContaxGS.book Page 5 Friday, August 20, 2010 1:53 PM6 Installation
• Cabling — The cabling is routed to avoid sources of electrical noise, such
as radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures.
• Ambient Requirements — The ambient unit operating temperature range
is 0 to 45ºC (32 to 113ºF) at a relative humidity of 10% to 90%, noncondensing.
Unpacking
Package Contents
While unpacking the switch, ensure that the following items are included:
• Switch
• AC power cable
• RS-232 cable with a male 8-pin RJ-45 connector
• Self-adhesive rubber pads
• Rack-mount kit for rack installation
• Documentation CD
Unpacking the Switch
NOTE: Before unpacking the switch, inspect the package and immediately report
any evidence of damage.
To unpack the switch:
1 Place the box on a clean flat surface.
2 Open the box or remove the box top.
3 Carefully remove the switch from the box and place it on a secure and
clean surface.
4 Remove all packing material.
5 Inspect the switch and accessories for damage. Report any damage
immediately to the dealer.
ContaxGS.book Page 6 Friday, August 20, 2010 1:53 PMInstallation 7
Installing the Switch
The PowerConnect 5500 Series switches can be:
• Installed on a rack
• Placed on a flat surface
Installing in a Rack
CAUTION: Disconnect all cables from the unit before mounting the switch in a
rack or cabinet.
CAUTION: When mounting multiple switches into a rack, mount the switches
from the bottom up.
To install the switch in a rack:
1 Place the supplied rack-mounting bracket on one side of the switch,
ensuring that the mounting holes on the switch line up to the mounting
holes on the rack-mounting bracket.
Figure 1-1 illustrates where to mount the brackets.
Figure 1-1. Bracket Installation for Rack Mounting
2 Insert the supplied screws into the rack-mounting holes and tighten with a
screwdriver.
ContaxGS.book Page 7 Friday, August 20, 2010 1:53 PM8 Installation
3 Repeat the process for the rack-mounting bracket on the other side of the
switch.
4 Insert the unit into the 48.26-cm (19-inch) rack, ensuring that the
rack-mounting holes on the switch line up to the mounting holes on the
rack.
5 Secure the unit to the rack with the rack screws (not provided). Fasten the
lower pair of screws before the upper pair of screws. Ensure that the
ventilation holes are not obstructed.
Installing on a Flat Surface
Install the switch on a flat surface if it is not installed on a rack. The surface
must be able to support the weight of the switch and the switch cables.
To install the switch on a flat surface:
1 Attach the self-adhesive rubber pads on each marked location on the
bottom of the chassis.
2 Set the switch on a flat surface, leaving 5.08 cm (2 inches) on each side
and 12.7 cm (5 inches) at the back.
3 Ensure that the switch has proper ventilation.
Connecting the Switch to Power Supplies
Each switch in the stack must be connected to an AC power supply.
The power connectors are positioned on the back panel. Connecting a
Redundant Power Supply (RPS) or Modular Power Supply (MPS) is optional,
but recommended. The RPS or MPS connector is on the back panel of the
switch. The RPS is used for non-PoE switches and MPS is used for PoE
switches.

ContaxGS.book Page 8 Friday, August 20, 2010 1:53 PMGetting Started Guide 9
Stacking
Overview
Each switch is a member in a stack, although the stack may consist of only a
single switch. Up to eight switches are supported per stack.
All stacks must have a Master unit, and may have a Master Backup unit. All
other switches are connected to the stack as members (slaves).
Stacking Switches
PowerConnect 5500 series switches use two HDMI 10G ports for stacking.
To connect the switches in the stack:
1 Insert one end of an HDMI cable into the left-hand HDMI port on the
switch at the top of the stack and the other end into the right-hand HDMI
port of the switch immediately below it.
2 Repeat this process until all switches are connected.
3 (Optional) Connect the left-hand HDMI port of the switch at the bottom
of the stack to the right-hand HDMI port of the switch at the top of the
stack. This step provides increased bandwidth and redundancy.

Unit ID Assignment
Each switch in the stack has a unique unit ID that defines the unit’s position
and function in the stack.
Figure 2-2 describes the stacking LEDs on the front panel of the switch.
Figure 2-2. Stacking LEDs on Front Panel
The Unit ID of each switch can be either automatically assigned or manually
assigned, as described below.
Automatic Assignment
When you power-up the stack, each switch is assigned a unique Unit ID. This
is displayed on the front panel of the switch, as shown in Figure 2-2.
The switch that is assigned Unit ID 1 is the Master unit, by default. The
switch that is assigned Unit ID 2 is the Master Backup unit.

ContaxGS.book Page 13 Friday, August 20, 2010 1:53 PM14 Configuring the Switch
Connecting the Switch to the Terminal
The switch is configured and monitored through a terminal desktop system
that runs terminal emulation software. The switch connects to the terminal
through the console port.
To connect the switch to a terminal:
1 Connect an RS-232 cable to a VT100-compatible terminal or the serial
connector of a desktop system running terminal emulation software.
2 Connect the RS-232 cable to the switch console port on the front panel of
the switch (see Figure 3-1) using an 8-pin RJ-45 male connector.
Figure 3-1. Front-Panel Console Port
3 Set the terminal emulation software as follows:
a Select the appropriate serial port to connect to the switch.
b Set the data rate to 9600 baud.
c Set the data format to 8 data bits, 1 stop bit, and no parity.
d Set Flow Control to none.
e Select VT100 for Emulation mode within your communication
software.
f Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that
the setting is for Terminal keys (not Windows keys).
NOTE: You can connect a console to the console port on any unit in the stack, but
stack management is performed only from the stack master (Unit ID 1 or 2).

Booting the Switch
After the local terminal is connected, turn on power. The switch then goes
through power-on self-test (POST). POST runs every time the switch is
started and checks hardware components, to determine if the switch is
operational before completely booting. If the system detects a critical
problem, the boot process stops. If POST passes successfully, a valid
executable image is loaded into RAM. POST messages are displayed on the
terminal and indicate test success or failure.
The boot process runs for approximately 40-45seconds.
When the boot process completes, the following LEDs are lit, as shown in
Figure 3-2:
• Power
• Status
• Fan (should be green)
• RPS (if it is being used)

Configuring the Stack
The switch is always considered to be a stack of switches even if the stack only
contains a single switch. If there is more than one switch in the stack, each
switch must be configured individually. See "Unit ID Assignment" for
instructions on how to configure the stack.
Configuration Using the Setup Wizard
The Setup Wizard guides you through the initial switch configuration to get
the system up and running as quickly as possible. Note that you can skip the
Setup Wizard and configure the switch manually through the CLI.
The Setup Wizard configures the following fields:
• SNMP Community String and SNMP Management System IP address
(optional)
• Username and password
• Management switch IP address
• IP subnet mask
• Default gateway IP address
NOTE: The Setup Wizard assumes the following:
• The PowerConnect switch was never configured before and is in the same
state as when you received it.
• The PowerConnect switch booted successfully.
• The console connection is established and the console prompt is displayed on
the screen of a VT100 terminal switch.
Connect the Master unit to a terminal. You can identify the Master unit by
the illuminated Master LED on the front panel of the switch (see Figure 2-2).
To configure the system using the Setup Wizard:
1 Obtain the following information from the network administrator:
• SNMP Community String and SNMP Management System IP
address (optional)
• Username and password
ContaxGS.book Page 16 Friday, August 20, 2010 1:53 PMConfiguring the Switch 17
• The IP address to be assigned to the VLAN 1 interface through which
the switch is to be managed (by default, every external and internal
port is a member of the VLAN 1)
• The IP subnet mask for the network
• The default gateway (next hop router) IP address for configuring the
default route
2 Boot the Master unit. The system automatically prompts you to use the
Setup Wizard.
The Setup Wizard displays the following information:

Chargement de la batterie
REMARQUE : Avec Dell™ ExpressCharge™, l'adaptateur secteur charge une batterie complètement déchargée
en 1 heure si l'ordinateur est éteint. La durée de chargement est plus longue lorsque l'ordinateur est sous tension.
Vous pouvez laisser la batterie dans l'ordinateur aussi longtemps que vous le souhaitez. Les circuits internes de la
batterie préviennent toute surcharge.
Lorsque vous branchez l'ordinateur sur une prise secteur ou que vous installez une batterie pendant que
l'ordinateur est branché sur une prise secteur, l'ordinateur vérifie le niveau de charge et la température de
la batterie. Au besoin, l'adaptateur secteur charge alors la batterie et maintient le niveau de charge.
Si la batterie est chaude parce qu'elle se trouvait dans l'ordinateur ou en raison de la température
extérieure, il est probable qu'elle ne se charge pas lorsque vous branchez l'ordinateur sur une prise
secteur.
Si le voyant clignote alternativement vert et orange, la batterie est trop chaude pour être chargée.
Débranchez l'ordinateur de la prise secteur et laissez refroidir l'ordinateur et la batterie jusqu'à ce qu'ils
atteignent la température ambiante. Branchez alors l'ordinateur sur une prise secteur et continuez à
charger la batterie.
Pour plus d'informations sur la résolution des problèmes liés à la batterie, reportez-vous à la section
« Problèmes d'alimentation » à la page 97.
Remplacement de la batterie
PRÉCAUTION : Avant d'exécuter ces procédures, éteignez votre ordinateur, débranchez l'adaptateur secteur de
la prise secteur et de l'ordinateur, débranchez le modem de la prise murale et de l'ordinateur et retirez les autres
câbles externes de l'ordinateur.42 Utilisation d'une batterie
AVIS : Vous devez retirer tous les câbles externes de l'ordinateur pour éviter d'endommager les connecteurs.
PRÉCAUTION : L'utilisation d'une batterie non compatible peut accroître le risque d'incendie ou d'explosion.
Ne remplacez la batterie que par une batterie compatible achetée auprès de Dell. La batterie est conçue pour
fonctionner avec votre ordinateur Dell™, n'utilisez pas la batterie d'un autre ordinateur.
AVIS : Si vous décidez de remplacer la batterie alors que l'ordinateur est en veille, vous disposez d'une minute
pour effectuer cette opération. Passé ce délai, l'ordinateur s'éteint et toutes les données non enregistrées sont
définitivement perdues.
Pour retirer la batterie :
1 Si l'ordinateur est connecté à une station d'accueil, déconnectez-le. Pour obtenir des instructions,
consultez la documentation qui accompagne la station d'accueil.
2 Assurez-vous que l'ordinateur est éteint ou en mode de gestion de l'alimentation.
3 Faites glisser en le maintenant le loquet de fermeture de la baie de la batterie, situé sous l'ordinateur,
puis retirez la batterie de la baie.
Pour remettre en place la batterie, suivez la procédure de retrait dans l'ordre inverse.
Stockage de la batterie
Retirez la batterie de l'ordinateur lorsque vous rangez ce dernier pendant une période prolongée. Sinon,
la batterie finira par se décharger. Après une longue période de stockage, rechargez complètement la
batterie avant de l'utiliser (reportez-vous à la section « Chargement de la batterie » à la page 41).

Pilotes
Qu'est-ce qu'un pilote ?
Un pilote est un programme qui contrôle un périphérique, une imprimante, une souris ou un clavier par
exemple. Tous les périphériques nécessitent un pilote.
Un pilote sert d'interprète entre le périphérique et tout autre programme qui l'utilise. Chaque
périphérique dispose de son propre jeu de commandes spécialisées que seul son pilote reconnaît.
Lorsque Dell livre l'ordinateur, les pilotes requis sont déjà installés—aucune installation ou configuration
supplémentaire n'est nécessaire.
AVIS : Le CD Drivers and Utilities peut contenir des pilotes pour des systèmes d'exploitation qui ne sont pas
installés sur votre ordinateur. Assurez-vous que vous installez les logiciels appropriés à votre système
d'exploitation.
De nombreux pilotes, tels que le pilote du clavier, sont fournis avec le système d'exploitation Microsoft®
Windows®. Vous devez installer des pilotes si vous :
• Mettez à jour votre système d'exploitation ;
• Réinstallez votre système d'exploitation ;
• Connectez ou installez un nouveau périphérique.
Identification des pilotes
Si vous rencontrez des difficultés avec un périphérique, identifiez le pilote à l'origine du problème et

Utilisation du programme de configuration du système
REMARQUE : Il se peut que votre système d'exploitation configure automatiquement la plupart des options
disponibles dans le programme de configuration ; les options que vous avez configurées à l'aide de ce
programme sont alors ignorées. Seule exception, l'option External Hot Key (Touche rapide externe), que vous
pouvez désactiver ou activer via le programme de configuration du système uniquement. Pour plus
d'informations sur la configuration des fonctions de votre système d'exploitation, reportez-vous au Centre
d'aide et de support Windows. Pour accéder au Centre d'aide et de support, reportez-vous à la page 14.
Les écrans de configuration du système affichent les informations sur la configuration courante et
les paramètres de votre ordinateur, par exemple :
• Configuration du système
• Paramètres de configuration de base des périphériques
• Paramètres de sécurité du système et mot de passe de disque dur
• Paramètres de gestion de l'alimentation
• Paramètres de configuration d'amorçage (démarrage) et d'affichage
• Paramètres de la station d'accueil
• Paramètres de contrôle sans fil
AVIS : Ne modifiez les paramètres du programme de configuration du système que si vous êtes un utilisateur
expérimenté en informatique ou si vous êtes assisté par un représentant du support technique de Dell.
Certaines modifications risquent de provoquer un mauvais fonctionnement de l'ordinateur.
Affichage de l'écran de configuration du système
1 Mettez votre ordinateur sous tension (ou redémarrez-le).
2 Lorsque le logo DELL™ apparaît, appuyez immédiatement sur . Si vous attendez trop
longtemps et que le logo Windows apparaît, attendez encore jusqu'à ce que le bureau Windows
s'affiche. Ensuite, arrêtez votre ordinateur et faites une nouvelle tentative.
Programme de configuration du système
L'écran de configuration du système se compose de trois fenêtres d'information. La fenêtre de
gauche contient une hiérarchie développable des catégories de contrôle. Si vous sélectionnez
(mettez en surbrillance) une catégorie (comme Système, Périphériques intégrés ou Vidéo) et que
vous appuyez sur , vous pouvez afficher ou masquer les sous-catégories connexes. La
fenêtre de droite contient des informations sur la catégorie ou sous-catégorie sélectionnée dans la
fenêtre de gauche. 166 Annexe
La fenêtre du bas vous indique comment contrôler les fonctions des touches du programme de
configuration du système. Utilisez ces touches pour sélectionner une catégorie, modifier les paramètres,
ou quitter le programme de configuration du système.
Options fréquemment utilisées
Certaines options nécessitent le redémarrage de l'ordinateur pour que les nouveaux paramètres entrent
en vigueur.
Modification de la séquence d'amorçage
La séquence d'amorçage, ou ordre de démarrage, indique à l'ordinateur où chercher pour trouver le logiciel
requis pour démarrer le système d'exploitation. Vous pouvez contrôler la séquence d'amorçage et
activer/désactiver les périphériques à l'aide de la page Ordre d'amorçage du programme de configuration
du système.
REMARQUE : Pour modifier la séquence d'amorçage sur une base ponctuelle, reportez-vous à la section
« Exécution d'un amorçage ponctuel » à la page 167.

notamment les suivants :
• Lecteur de disquette
• Unité de disque dur interne
• Périphérique de stockage USB
• Lecteur de CD/DVD/CD-RW
• Disque dur de la baie modulaire
REMARQUE : Seuls sont amorçables les périphériques précédés d'un numéro.
Pendant la procédure d'amorçage, l'ordinateur commence par le début de la liste, puis analyse chacun des
périphériques activés à la recherche des fichiers de démarrage du système d'exploitation. Lorsque les
fichiers ont été trouvés, l'ordinateur arrête la recherche et fait démarrer le système d'exploitation.
Pour définir les périphériques d'amorçage, sélectionnez (mettez en surbrillance) un périphérique en
appuyant sur les touches fléchées haut ou bas, puis activez ou désactivez le périphérique ou modifiez son
ordre dans la liste.
• Pour activer ou désactiver un périphérique, sélectionnez-le et appuyez sur la barre d'espacement. Les
éléments activés sont précédés d'un numéro ; ceux qui ne le sont pas ne sont pas précédés d'un
numéro.
• Pour modifier l'ordre d'un périphérique dans la liste, sélectionnez-le et appuyez sur (h) ou
(b) pour déplacer le périphérique vers le haut ou le bas.
Les modifications que vous apportez à la séquence d'amorçage sont prises en compte dès que vous les
enregistrez et que vous quittez le programme de configuration du système.Annexe 167
Exécution d'un amorçage ponctuel
Vous pouvez définir une séquence d'amorçage ponctuelle sans devoir passer par le programme de
configuration du système. (Vous pouvez également utiliser cette procédure pour initialiser Dell
Diagnostics sur la partition de l'utilitaire de diagnostics de votre disque dur.)
1 Arrêtez l'ordinateur à l'aide du menu Démarrer.
2 Connectez l'ordinateur à une prise secteur.
3 Allumez l'ordinateur. Lorsque le logo DELL apparaît, appuyez immédiatement sur . Si vous
attendez trop longtemps et que le logo Windows apparaît, attendez encore jusqu'à ce que le bureau
Windows s'affiche. Éteignez alors votre ordinateur et faites une nouvelle tentative.
4 Lorsque la liste des périphériques d'amorçage apparaît, sélectionnez celui que vous voulez utiliser pour
l'amorçage, puis appuyez sur .
L'ordinateur démarre à partir du périphérique sélectionné.
Au prochain redémarrage de l'ordinateur, l'ordre d'amorçage précédent sera restauré.
Nettoyage de votre ordinateur
PRÉCAUTION : Avant de commencer toute procédure de cette section, consultez et respectez les consignes de
sécurité du Guide d'information sur le produit.
Ordinateur, clavier et écran
PRÉCAUTION : Débranchez l'ordinateur de la prise électrique avant de le nettoyer. Retirez toute batterie
installée. Nettoyez votre ordinateur avec un chiffon doux humecté d'eau. N'utilisez pas de liquide ni d'aérosol
nettoyants, ceux-ci peuvent contenir des substances inflammables.
• Utilisez une bouteille d'air comprimé pour retirer la poussière entre les touches du clavier, ainsi que les
dépôts de poussière sur l'écran.
AVIS : Pour éviter d'endommager l'ordinateur ou l'écran, ne vaporisez pas de liquide de nettoyage directement sur
l'écran. Utilisez uniquement les produits conçus particulièrement pour le nettoyage d'écrans et suivez les
instructions fournies avec le produit.
• Utilisez un chiffon doux, non pelucheux, humecté d'eau ou un nettoyant d'écran. N'utilisez pas
d'alcool ni de nettoyant à base d'ammoniac. Essuyez l'écran doucement du centre vers les bords jusqu'à
ce qu'il soit propre et exempt de traces de doigt. Veillez à ne pas trop appuyer sur l'écran.
• Humectez un chiffon doux, non pelucheux, d'eau et essuyez l'ordinateur et le clavier. Veillez à ne pas
laisser l'eau du chiffon s'infiltrer entre la tablette tactile et le repose-mains qui l'entoure.
Tablette tactile
1 Arrêtez l'ordinateur et mettez-le hors tension. Reportez-vous à la section « Mise hors tension de
l'ordinateur » à la page 111.

l'entoure.
Lecteur de disquette
AVIS : N'essayez pas de nettoyer les têtes de lecture avec une tige de nettoyage. Vous risqueriez de déranger
accidentellement l'alignement des têtes et d'empêcher le fonctionnement du lecteur.
Nettoyez le lecteur de disquette à l'aide d'une trousse de nettoyage que vous trouverez dans le
commerce. Ces trousses comportent des disquettes prétraitées qui permettent d'enlever les dépôts
accumulés au cours d'une utilisation normale.
CD et DVD
AVIS : Utilisez toujours de l'air comprimé pour nettoyer la lentille du lecteur et suivez les instructions fournies avec
l'air comprimé. Ne touchez jamais la lentille qui se trouve à l'intérieur du lecteur.
Si vous avez des problèmes pendant la lecture de vos CD ou DVD (des sauts pendant la lecture par
exemple), nettoyez les disques.
1 Tenez le disque par son bord extérieur. Vous pouvez également toucher le bord intérieur de l'orifice
central.
AVIS : Pour éviter d'abîmer la surface, n'essuyez pas le disque par mouvement circulaire.
2 Avec un chiffon doux et non pelucheux, nettoyez doucement la partie inférieure du disque (côté sans
étiquette) en suivant une ligne droite depuis le centre jusqu'au bord extérieur.
Si la poussière ne part pas, utilisez de l'eau ou une solution diluée d'eau et de savon doux. Certains
produits vendus dans le commerce nettoient les disques et les protègent contre la poussière, les
empreintes et les rayures. Les produits de nettoyage pour CD peuvent également être utilisés sur les
DVD sans aucun risque.
