Configuring and Troubleshooting Line Card Interfaces
Configuring the 1-Port Channelized OC-12/STM-4 (DS3) Line Card
The following procedure describes how to perform a basic controller configuration. After you verify that
the new line card is installed correctly, enter the privileged EXEC mode with the enable command. The
system prompts you for a password if one is required. Use the configure command to configure the
controller.
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-12/STM-4 (DS3) 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-12/STM-4 (DS3) line card. Press
the Enter key after each configuration step unless otherwise noted.
Step 1 Enter global configuration mode by entering configure terminal at the privileged EXEC prompt:
Router# configure terminal
Router(config)#
Step 2 Enter controller configuration mode by entering the controller OC-12 slot/port global configuration
command and specify the router slot number and port number:
Router(config)# controller OC12 1/0
Router(config-controller)#
Step 3 Set the clock source by entering the clock source controller configuration command and specify line or
internal:
Router(config-controller)# [no] clock source {line | internal}
Router(config-controller)#
Use the no form of this command to restore the default value, line.
Step 4 To change the OC-12 controller payload scrambling:
Router(config-controller)# [no] scramble
Router(config-controller)#
