Configuring the Interfaces
Shutting Down an Interface
Before you remove an interface that you will not replace, or replace port adapters, 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:
Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using
the EXEC Command Interpreter" section for instructions.)
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)#
Step 3 Shut down interfaces by entering the interface pos subcommand (followed by the interface address of
the interface), and then enter the shutdown command.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or
exit to exit the configuration mode and return to the EXEC command interpreter.
Table 4-2 shows the shutdown command syntax for the supported platforms.
