threshold
A
range

i

n

which

you

expect

your

network

to

perform.

If

a


threshold

is

exceeded

or

goes
below

the
expected
bounds,

you

examine

the

areas

for

potential

problems.

You

can

create

thresholds

for

a

specific
device.
traceroute
A
diagnostic
tool
that

helps

you

understand

why

ping

fails
or

why

applications

time

out.

Using

it,

you
can
vi

ew

each

hop

(or

gat

eway)

on

the

route

t

o

your

device

and

how

long

each

took.

U
URI
Uniform
Resource

Identifier.

Type

of

formatted
identifier
that

encapsulates

the

name
of
an

Internet
object,
and

labels

it

with

an

identification

of

the

name

space,

thus

producing

a

member

of

the

universal

of

names

in

and

of

addresses

referring

to

registered

protocols

or

[RFC

user
role
A
mechanism

for

granting

access

to

features

and
functionality
to

a
user
account.

The
Cisco

Application
Networking
Manager

includes

four

predefined

roles:

System

Administrator,

Server

Manager,

Network
Manager,
and

Service

Provider

Customer.
V
virtual
context
A
concept

that

allows

users

to

partition
an

ACE

into

multiple

virtual

devices.

Each

virtual

context
contains
its

own

set

of

policies,

interfaces,

resources,

and

administrators,

allowing

administrators

to
more
efficiently

manage

system

resources

and

services.
There
are

two

types

of

contexts;

the

Admin

context

and

a

user

context.

The

Admin

context

is

the

default
context
that

the

ACE

provides.

The

Admin

context,

which

contains

the

basic

settings

for

each

virtual
device
or

context,

allows

a

user

to

configure

and

manage

all

contexts.

When

a

user

logs

into

the

Admin
context,
he

or

she

has

full

system

administrator

access

to

the

entire

ACE

and

all

contexts

and

objects
within
it.

The

Admin

context

provides

access

to

network-wide

resources,

for

example,

a

syslog

server
or
context

configuration

server.

All

global

commands

for

ACE

settings,

contexts,

resource

classes,

and
so
on,

are

available

only

in

the

Admin

context.
A
user

context,

which

is

created

by

a

user,

has

access

to

the

resources

in

which

the

context

was

created.
For
example,

a

user

context

that

was

created

by

an

administrator

while

in

Admin

context,

by

default,
has
access

to

all

resources

in

an

ACE

device.

Any

user

created

by

someone

in

a

user-defined

context,
only
has

access

to

the

resources

within

that

context.

In

a

ddition,

roles

are

assigned

to

users,

which
determine
the

commands

and

resources

that

are

available

to

that

user.
VLAN
Virtual
LAN.

Group

of

devices

on

one

or

more

LANs

that

are

configured

(using

management
software)
so
that

they

can

communicate

as

if

they

were

attached

to

the

same

wire,

when

in

fact

they

are

located
on
a

number

of

different

LAN

segments.

Because

VLANs

are

based

on

logical

instead

of

physical
connections,
they

are

extremely

flexible.

virtual
server
A
virtual

server

represents

groups

of

real

servers

and

are

associated

with

a

real

server

farm.
