Finding un-used Ports on CatOS, and IOS.

Hi, all. I had a quick question about finding unused ports in switches. Unused meaning ports that have not received any traffic in say 30 days.

Besides doing a manual baseline of ports, looking every day etc. Or sending SNMP "port down" messages to CiscoWorks then munching through the data. Is there a command either in CatOS, or in IOS that will let you look at the last time the port saw traffic? Or went down, in a nice format?

If you are using IOS, there are certain outputs for the "show interface" command like "Last input 00:00:13, output 00:00:05" . Wondering if it is related to what you want.
