How to tell if a port has not been used in a while

ITAdmin777

Hi folks,

In search of a way to find unused ports.  The caveat is that not all devices on turned on 24/7.....so found this command some time ago!

 show int | i proto.*notconnect|proto.*administratively down|Last in.* [6-9]w|Last in.*[0-9][0-9]w|[0-9]y|disabled|Last input never, output never, output hang never

I ran the above on a few of our switches and does provide "not connected port information". However can someone please decipher the above so I know what it all means?  please and thanks!

Also,  how can the syntax be altered for say 6 months? or even a year.

Trying to get our wiring closets under control.

Thanks in advance.
