WebLoop guard. NOTE: This feature is different from STP loop protection. A loop in a layer-2 network results in broadcast storms that have far-reaching and unwanted effects. Loop guard helps to prevent loops. When loop guard is enabled on a switch port, the port monitors its subtending network for any downstream loops.
