Configuring the Interfaces
Configuring the Interfaces
After you verify that the new 6T3 line card is installed correctly (the STATUS LED goes on), use the
privileged-level configure command to configure the new interfaces. Have the following information
available:
•

•
•
•
If you installed a new 6T3 line card or if you want to change the configuration of an existing interface,
you must enter configuration mode to configure the new interfaces. If you replaced a 6T3 line card that
was previously configured, the system recognizes the new interfaces and brings each of them up in their
existing configuration.
For a summary of the configuration options available and instructions for configuring interfaces on a
6T3 line card, refer to the appropriate configuration publications listed in the
section on page
You execute configuration commands from the privileged level of the EXEC command interpreter,
which usually requires password access. Contact your system administrator, if necessary, to obtain
password access. (See the
explanation of the privileged level of the EXEC.)

Shutting Down an Interface
Before you remove an interface that you will not replace, or replace line cards, use the shutdown
command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or
reconfigured interface processor. When you shut down an interface, it is designated administratively
down in the show command displays.
Follow these steps to shut down an interface:
Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the
Step 1
the EXEC Command Interpreter" section on page 4-1
Step 2
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the
source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Shut down interfaces by entering the interface serial subcommand (followed by the interface address
Step 3
of the interface), and then enter the shutdown command.
