A method of determining an Ethernet LAN switch topology including the steps of a) establishing a communications link between a network management server and a switch in an Ethernet LAN, thereby defining the switch as a root switch, b) identifying each of a plurality of switches attached to the Ethernet LAN, the each of the plurality of switches includes at least one identifiable port, c) generating a mapping of each of the switches, the mapping including a list for each of the ports of the switches that each of the ports sees, d) eliminating from the mapping each upwardly looking one of the ports, e) identifying in the mapping at least one leaf connected to at least one of the ports, f) maintaining in a topological mapping at least one relationship between the leaves and the ports connected to the leaves, g) eliminating from the list for each of the ports each of the leaves that each of the ports sees, and h) repeating steps e)-g) until all of the leaves are identified.
