ABSTRACT:
In one embodiment of the invention, a method for detecting a network loop problem in a network, includes: selecting a known static address of a selected device which should normally be detected at not more than one port of a downstream device; determining if the static address is detected in more than one port in a downstream device, wherein the current downstream device includes a first port which normally detects the known static address and a second port; if the static address is detected at the second port of the current downstream device, then determining the connection to the second port and if the connection to the second port is a leaf, then identifying the leaf as a misbehaving node, and if the connection to the second port is not a leaf, then evaluating a next downstream device.
