Configuring the PA-T3 Interfaces 8-9
Shutting Down an Interface
The example that follows is for Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200
series routers:
Router# show interfaces serial 1/0
Serial 1/0 is administratively down, line protocol is down
Hardware is M1T-T3 pa
[display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a VIP2, use the
show interfaces serial slot/port adapter/interface command to display the specific
interface, or use the show interfaces command, without variables, to display the status of
all interfaces in the system.
The example that follows is for a VIP2:
Router# show interfaces serial 1/1/0
Serial 1/1/0 is administratively down, line protocol is down
Hardware is cyBus PODS3 Serial
[display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a
Catalyst RSM/VIP2, use the show interfaces serial port adapter/interface command to
display the specific interface, or use the show interfaces command, without variables, to
display the status of all interfaces in the system.
The example that follows is for a Catalyst RSM/VIP2:
Router# show interfaces serial 1/0
Serial 1/0 is administratively down, line protocol is down
Hardware is cyBus PODS3 Serial
[display text omitted]
Step 8 Reenable the interfaces. To do so, repeat the previous steps, but use the no shutdown
command in Step 4, and then write the new configuration to memory as follows.
The example that follows is for the Cisco 7100 series, Cisco 7200 series, or
Cisco uBR7200 series routers:
Router(config)# interface serial 1/0
Router(config-if)# no shutdown
Ctrl-Z
Router#
Router# copy running-config startup-config
[OK]
Router# show interfaces serial 1/0
Serial 1/0 is up, line protocol is up
Hardware is M1T-T3 pa
