3.
Importing
the
device
information
into
the

ANM

database

to

add

the
device

into

the

Devices

table.
See
the

“Importing

Network

Devices

into

ANM”

section

on

pa

ge

5-10 .
4.
After
importing

a
module
host

device,

such

as

a

Catalyst

6500

series

chassis,

you

can

add

ACE
modules
and

CSMs

into

the

ANM

database.

See

the

“Importing

ACE

Modules

after

the

Host

Chassis
has
been

Imported”

section

on

page

5-16

or

the

“Importing

CSM

Devices

after

the

Host

Chassis

has
been
Imported”

section

on

page

5-19 .
5.
After
you

start

a

discovery

job,

you

can

monitor

its

status.

See

the
“Monitoring
IP

Discovery

Status”
section
on

page

5-33 .
ANM
offers

multiple

ways

to

accomplish

some

of

these

steps.

For

example,

you

can

either

run

a
discovery
job

to

identify

the

available

chassis,

and

then

choose

the

ones

to

import,

or

you

can

import

a
specific
chassis

into

the

ANM

database.
To
add

a

chassis

without

running

discovery,

see

the

“Importing

Cisco

IOS

Host

Chassis

and

Chassis
Modules”
section

on

page

5-11 .
See
the

Supported

Devices

Table

for

Cisco

Application

Networking

Manager

for

more

information

about
the
devices

that

ANM

supports.

Preparing
Devices

for

IP

Discovery
This
section

describes

how

to

prepare

your

Cisco

devices

for

IP

Discovery

by

enabling

SSH

and

Telnet
on
each

device

and

by

configuring

device

SSH

and

Telnet

credentials

though

ANM.

These

tasks

enable
ANM
to

communicate

with

the

devices

and

collect

data

from

them.
Caution
IP
Discovery

sends

unencrpyted

cr

edentials

(Telnet
and
SNMP)

to

all

devices

on

the

specified
subnet
who
respond

to

the

associated

ports.

This

is

a

potential

security

risk

because

credentials

are

broadcast
out
to

one

or

more

networks.

IP

Discovery

may

also

find

devices

that

cannot

be

imported

or

may

not

be
able
t

o

locate

devices

that

could

be

imported.
Guidelines
and

Restrictions
Network
latency

can

prevent

ANM

from

establishing

a

communication

link

with

a

device

that

you

want
to
import.

When

ANM

is

providing

the

device

with

the

device

credentials

(username

and

password),

by
default
it

waits

two

seconds

after

providing

the

device

username

for

the

password

prompt

to

appear.

The
link
times

out

when

it

takes

longer

than

two

seconds

for

the

next

prompt

to

appear.

For

information

about
possible
causes

of

network

latency

that

can

create

this

issue

and

how

to

adjust

the

ANM

timeout

value,
see
the

“Modifying

the

ANM

Timeout

Setting

to

Compensate

for

Network

Latency”

section

on

page

5-9 .
Before
You

Begin
Ensure
that

you

have

enabled

SSH

and

Telnet

in

your

Cisco

network

devices

by

performing

the

tasks
described
in

the

following

sections:

•
Enabling
SSH

or

Telnet
Access
on

Ca

talyst

6500

Series
Switches
and

Cisco
7600
Series

Routers,
