IP

Address and

Subnetwork

Mask

(IP only)

In order for SNMP to run properly, every device

in

the

network

must

have

a

unique

IP

address and subnetwork mask. In

a

classical

IP

subnetwork,

you

must

use

the

SET

DEVICE

IP_ADDRESS

command to

assign

a

unique IP

address and

subnetwork mask

to

the

6416SW

For

example,

the

following

command

sets a

unique

IP address

for

a

Classical

IP

over

ATM

subnetwork

on

the

6416SW

and

a

subnetwork

mask

for

an ATM

class

C device:

￿ONcoreATM> set device ip_address atm 195.44.45.48 FF.FF.FF.

[ENTER]

The subnetwork mask is specific

for

each

type

of

Internet class. In general, the

subnetwork mask is the group of

common characters to the left of the IP address.

(These characters are also called the network

ID.)

The

host

address

is

the

group

of

unique

characters to

the

right

of

the

IP

address.

The following command sets the subnetwork mask for an ATM class B device:

￿ONcoreATM> set device ip_address atm 195.44.45.48 FF.FF. . [ENTER]
