Interface Processor Installation Procedures
Shutting Down an Interface
If you are installing a new interface processor or replacing an existing interface processor, proceed to
the “Removing an Interface Processor” section on page 24.
If you are removing an interface processor that you will not replace, or replacing an interface processor
component, we recommend you 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.
Use the following standard procedure to shut down any interface:
Step 1 Enter the privileged level of the EXEC command interpreter. (Refer to the “Using the EXEC Command
Interpreter” section on page 28 for instructions.)
Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be
the source of configuration subcommands as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 3 Specify the slot/port address of the first interface that you want to shut down by entering the
subcommand interface type slot/port, where the type is serial, ethernet, and so forth, and slot/port is
the interface processor slot followed by the port number to be shut down.
Following is an example for the first interface port on an interface processor in interface processor slot 0:
Router(config)# interface type 0/0
Step 4 Enter the shutdown command as follows:
Router(config-if)# shutdown
Step 5 To shut down additional interfaces, enter the slot/port address of each additional interface followed by
the shutdown command. When you have entered all the interfaces to be shut down, press Ctrl-Z (hold
down the Control key while you press Z) to exit configuration mode and return to the EXEC command
interpreter prompt, as follows:
Router(config-if)# interface type 0/1
Router(config-if)# shutdown
Router(config-if)# interface type 0/2
Router(config-if)# shutdown
Ctrl-Z
Step 6 Write the new configuration to nonvolatile random access memory (NVRAM) as follows:
Router# copy running-config startup-config
[OK]
Router#
The system displays an OK message when the configuration has been stored.
Step 7 To verify that new interfaces are now in the correct state (shut down), use the show interface type
slot/port command to display the specific interface, or use the show interfaces command, without
variables, to display the status of all interfaces in the system.
Router# show interface type 0/0
(additional displayed text omitted from this example)
Type 1/0 is administratively down, line protocol is down
