Show connected (up) interfaces on cisco devices

Question

Is there any way to show a total count of interfaces that are in status "up" on a cisco router?

The purpose is to let a script go through all routers and show a summarization count of "up" interfaces.

Answer 1

You can show all interfaces that are up by:

show interfaces status | include connected

Then your script can count them.

The show interfaces status cli command shows you all interfaces. The interfaces that are "up" are in the connected state. The | include connected shows only the lines of the output that contain the word "connected".

Newer Cisco IOS contain a count parameter that can count lines which match a regex. This is not available on all IOS versions.

Answer 2

You may also use these commands:

sh ip int bri | include up
sh int des | include up
