A Cisco 12000 Series Router identifies an interface address by its line card slot number and port number,

in the format slot/port. The ATM interfaces on the line card are numbered starting from 0: a one-port

card has only port 0, while a four-port card has ports 0 to 3. For example, the slot/port address of the first

ATM interface on a ATM line card installed in line card slot 2 is 2/0.

Before you can use the configure command, you must enter the privileged level of the EXEC command

interpreter with the enable command. The router will prompt you for a password if one is set.

Use the following procedure to configure the ATM line card. Press the Return key after each

configuration step unless otherwise noted.

Step 1

Confirm that the router recognizes the card by entering the show version command:

Router# show version

Step 2

Check the status of each port by entering the show interface command:

Router# show interface

Step 3

Enter configuration mode by entering the configure terminal command and specify that the console

terminal will be the source of the configuration subcommands:

Router# configure terminal

Step 4

At the prompt, specify the new ATM interface to configure by entering the interface command, followed

by the type (atm) and slot/port (line card slot number/port number).

For example, to configure port 3 of an ATM line card in interface processor slot 1, enter the interface

atm command as follows:

Router(config)# interface atm 1/3

Assign an IP address and subnet mask to the interface with the ip address configuration subcommand,

Step 5

as in the following example:

Router(config-if)# ip address 10.1.2.3 255.255.255.0

Configure a permanent virtual circuit (PVC), as in the following example:

Step 6

Router(config-if)# pvc 1/17

Note

Change the shutdown state to up and enable the interface by entering the no shutdown command:

Step 7

Router(config-if)# no shutdown

The no shutdown command passes an enable command to the ATM line card, which then begins

segmentation and reassembly (SAR) operations. It also causes the line card to configure itself based on

the most recent configuration commands received by the line card.

Note

OL-13004-01

For traffic to flow successfully, PVCs must use the same numbers on both ends of the link.

Add any other configuration subcommands required to complete this specific configuration.
