STP

Feature Overview

The STP feature is a link management protocol that provides path redundancy while preventing

undesirable loops in the network that are created by multiple active paths between stations. The STP

feature enables you to form a loop-free network topology. Depending upon the path cost and the priority

of the ports and bridges, the STP selects a bridge as a root bridge and forms a loop-free logical topology,

which ensures a single path between any two-end stations.
