Discovering
and

Adding

a

Device

Does

Not

Work
After
IP

discovery

has

checked

t

he

network

and

made

a

l

ist

of

devices

of


each

t

ype,

t

he

device

i

mport
may
have

failed

when

you

tried

to

import

the

device.

The

device

import

may

not

have

worked

because
IP
discovery

uses

Telnet

and

SNMP

to

discover

potential

devices,

while

ANM

requires

SSH

to

import

a
device.
So

it

is

likely

that

IP

discovery

may

have

found

some

devices

that

cannot

be

imported

or

may

not
have
found

devices

that

could

be

imported.
To
update

the

device

so

that

it

can

be

imported

by

ANM,

see

the

“Preparing

Devices

for

Import”

section
on
page

5-4 .
To
add

the

device,

use

the

Config

>

Devices

>

Add

method.

For

detailed

procedures,

see

the

“Importing
Network
Devices

into

ANM”

section

on

page

5-10 .

Using

Diagnosing
network

system-related

problems

happen

i

n

can

consume

a

considerable
amount
of

time

and

lead

to

frustration

even

for

a

system

expert.

When

a

critical

problem

occurs

within
the
ANM

system

or

the

network

components

managed

by

the

ANM,

you

can

use

the

troubleshooting

and
diagnostics
tools

provided

by

the

Lifeline

feature

to

report

to

the

Cisco

support

line

and

generate

a
diagnostic
package.

Support

engineers

and

developers

can

subsequently

reconstruct

your

system

and
debug
the

problem

using

the

comprehensive

information

captured

in

the

lifeline.
