Bridging: Loop detection using the MAC address move

When a MAC address appears in a different physical interface or within a different unit of the same physical interface and if this behavior occurs frequently, it is considered a MAC move. Configuration errors in the Layer 2 network can force traffic into never ending circular paths. Once there are loops in the Layer 2 network, one of the symptoms is frequent MAC moves. This feature explains how to use those frequent MAC moves to rectify the problem.
