The only thing I can think of is to look at the CAM table if there have been any macadress visible for a specific port.
A tool that use that type of information is the CW2000 - LMS bundle. Campus Manager - UserTracking functionality. It creates a table where you have macaddress,IP address,port,device, last seen etc...
in the same row.
Great to see input from you all and it seems very effective also.
But to make it more effective ,would like add one more point as use of any software for port audit will not make sense because mac address get refreshed in 20 sec which get cleared from Mac address table of all the switch port which is not in used and this activity get done trough ARP protocol.
Thank you all very much and correct me if I am wrong any point of time.
Does Cisco have any management software for monitoring port usage? I.E. which ports have/have not been logged in on during a given time period?
If you want to see the port usage traffic try configure the switch with SNMP with some server running with software like PRTG or MRTG with which you can see the whole switch individual port bandwidth usage.
Hope to Help !!
