Mac address tracing or detection on a cisco network

By mariner792005 ·
I work in the networking department of my university and we have had a few students have their laptops stolen. i was wondering if there was any way to do a mac address detection across all our switches on campus and have them give us an alert if the mac shows up anywere on campus. is there a tool or command set for the switches that would allow us to do this.

One app and possibly "MAC Address Notification Trap" feature

Digging around in Catalyst 3750 docs, it looks like maybe you can do that with the following feature:

"MAC Address Notification Traps"

MAC address notification enables you to track users on a network by storing the MAC address activity on the switch. Whenever the switch learns or removes a MAC address, an SNMP notification can be generated and sent to the NMS. If you have many users coming and going from the network, you can set a trap interval time to bundle the notification traps and reduce network traffic. The MAC notification history table stores the MAC address activity for each hardware port for which the trap is enabled. MAC address notifications are generated for dynamic and secure MAC addresses; events are not generated for self addresses, multicast addresses, or other static addresses.
