I am currently in the process of auditing network ports in a certain vlan to see if they need to stay in use or not. Is there any way (show command)that I can reliably tell if the port is in use still? I check the counters and the status of the interface, but those are only good for the last five minutes, and the machine connected could be off or something. Is there any way I can check when data was last sent on an interface?
Sorry if this is confusing. The switches I am auditing are running:
IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I9S-M), Version 12.1(19)EW1, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)
