Channelized and Electrical Interface Line Card Installation and Configuration

Configuring and Troubleshooting Line Card Interfaces

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

in the format slot/port. For example, the slot/port address of an interface on an 1-port channelized

OC-48/STM-16 ISE line card installed in line card slot 2 and port 0 is 2/0. Even if the card contains only

one port, you must use the slot/port notation.

Use the following procedure to configure the 1-port channelized OC-48/STM-16 ISE or 4-port

channelized OC-12/STM-4 ISE line card. Press the Enter key after each configuration step unless

otherwise noted.

Step 1 Enter the configure controller EXEC command to enter global configuration mode as follows:

router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Step 2 Select the controller:

router(config)# controller sonet 5/0

Step 3 Use the no shutdown interface command to change the shutdown state of the interface to up and enable

the interface:

router(config-controller)# no shut

Step 4 Add any other configuration subcommands required to enable routing protocols and adjust the interface

characteristics.

Step 5 Enter exit to exit configuration mode:

router(config-controller)# exit

router(config)# exit

router#

Step 6 Write the new configuration to nonvolatile random access memory (NVRAM) by using the copy

running-config startup-config command:

router# copy running-config startup-config

[OK]

router#

The default controller configuration parameters for the 1-port channelized OC-48/STM-16 ISE and

4-port channelized OC-12/STM-4 ISE line cards are listed in Table 25.
