Configuring and Troubleshooting Line Card Interfaces
Use the no form of this command to remove scrambling. The default value is scrambling.
Step 5 To change the OC-12 controller loopback mode:
Router(config-controller)# [no] loopback {line | internal}
Router(config-controller)#
Use the no form of this command to remove the loop.
Step 6 To change the shutdown state to up and enable the controller, enter the no shutdown controller
configuration command:
Router(config-controller)# [no] shutdown
Router(config-controller)#
The no shutdown command passes an enable command to the 1-port channelized OC-12/STM-4 (DS3)
line card. It also causes the line card to configure itself based on the previous configuration commands
sent.
Table 27 shows the default OC-12 controller configuration of a 1-port channelized OC-12/STM-4 (DS3)
line card in a Cisco 12000 Series Router.
Configuring the 2-Port Channelized OC-3/STM-1 (DS1/E1) 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 2-port channelized
OC-3/STM-1 (DS1/E1) 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 2-port channelized OC-3/STM-1 (DS1/E1) line card. Press
the Enter key after each configuration step unless otherwise noted.
Step 1 Enter configuration mode and specify that the console terminal will be the source of the configuration
subcommands:
Router# configure terminal
Router(config)#
