Cisco 7100 Series Routers—Example Output of the show interfaces Command
Following are examples of the show interfaces serial command from a Cisco 7120 series router. In these
examples, the eight serial interfaces (0 to 7) are on a port adapter in port adapter slot 3 of a Cisco 7120
series router; also, most of the status information for each interface is omitted. (Interfaces are
administratively shut down until you enable them.)
Router# show interfaces serial 3/0
Serial3/0 is up, line protocol is up
[Additional display text omitted from this example]
Router# show interfaces serial 3/1
Serial3/1 is up, line protocol is up
[Additional display text omitted from this example]
Router# show interfaces serial 3/2
Serial3/2 is up, line protocol is up
[Additional display text for remaining interfaces omitted]
Note
To use the show interfaces serial command with the Cisco 7140 series router, replace the interface
address arguments 3/0, 3/1, 3/2, 3/3, 3/4, 3/5, 3/6, and 3/7 with 4/0, 4/1, 4/2, 4/3, 4/4, 4/5, 4/6, and 4/7,
respectively.
Following is an example of the show interfaces serial command, which shows all of the information
specific to interface 0 on a PA-E3 installed in port adapter slot 3 of a Cisco 7120 series router:
