Shutting Down an Interface
PA-T3 Serial Port Adapter Installation and Configuration
8-8
Step 4 Enter the shutdown command as follows:
Router(config-if)# shutdown
Step 5 To shut down additional interfaces, enter the slot/port address (or slot/port
address/interface port for a VIP2) 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.
The example that follows is for the Cisco 7100 series, Cisco 7200 series, or
Cisco uBR7200 series routers:
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#
The example that follows is for a VIP2:
Router(config-if)# interface serial 1/1/0
Router(config-if)# shutdown
Router(config-if)# interface serial 1/1/1
Router(config-if)# shutdown
Ctrl-Z
Router#
The example that follows is for a Catalyst RSM/VIP2:
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#
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 on the
Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers, 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.
Cisco 7120 interface, followed by the type
(serial) and port adapter
number/interface port number
Router(config)# interface serial 3/0
Cisco 7140 interface, followed by the type
(serial) and port adapter
number/interface port number
Router(config)# interface serial 4/0
