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 [display text omitted]
