You can simply use "sh interface" then you will get the result of the interface status. If it show "up up" then it means the interface is active. For further prove the interface is working, you have to ping to the remote end IP address (e.g. "ping x.x.x.x"). If you can successful ping, then the interface is active and working.
You could also pop IP Accounting on the interface and do a "sh ip accouting" to see IP's talking and bytes moved. Or if you're after a bit more detail, then you could put on nbar protocol discovery to see what's going on in there.
Agreed to use IP accounting will show the bytes move, I could like to share that it will spend lots of CPU process. If there is high througput at the IP accounting enabled interface, it will cause high CPU utilization.
