Cisco Systems PA-4T manual Enter the shutdown command as follows

Shutting Down an Interface

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be 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 For a Cisco 7200 series, Cisco uBR7200 series, or Cisco 7100 series router, specify the

slot/port address of the first interface that you want shut down by entering the subcommand interface, followed by the type (serial) and slot/port (port adapter slot number/0). The example that follows is for a port adapter in slot 1:

Router(config)# interface serial 1/0

For a VIP2, specify the slot/port address of the first interface that you want shut down by entering the subcommand interface, followed by the type (serial) and slot/port (interface processor slot number/0). The example that follows is for a VIP2 in interface processor slot 3:

Router(config)# interface serial 3/0

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) or enter end to exit configuration mode and return to the EXEC command interpreter prompt.

For a Cisco 7100 series, Cisco 7200 series or Cisco uBR7200 series router, use the following example:

Router(config-if)#interface serial 1/0

Router(config-if)# shutdown

Router(config-if)#interface serial 1/1

Router(config-if)# shutdown

Ctrl-Z

Router#

For a VIP2, use the following example:

Router(config-if)#interface serial 3/0

Router(config-if)# shutdown

Router(config-if)#interface serial 3/0

Router(config-if)# shutdown

Ctrl-Z

Router#

Step 6 Write the new configuration to memory as follows:

Router# copy running-config startup-config

[OK]

Router#

The system displays an OK message when the configuration has been stored.

Step 7 Verify that new interfaces are now in the correct state (shutdown). To do so, use the show interfaces serial 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.
