Abstract

The switch port at which traffic associated with a specified media access control (MAC) address originates is searched for in a local area network (LAN). One or more switches receive a broadcast discovery message on a LAN subnet. Each switch determines whether the MAC address identified by the discovery message is associated with one of its ports. If the switch determines that the MAC address is associated with one of its ports, then the switch determines whether that port defines an edge of a searchable space. If the switch determines that that port defines an edge of the searchable space, then the switch issues a response message identifying the switch and the port.
