Command Usage
The Spanning Tree Algorithm (STA) can be used to detect and disable
network loops, and to provide backup links between switches, bridges or
routers. This allows the switch to interact with other bridging devices (that is,
an STA-compliant switch, bridge or router) in your network to ensure that only
one route exists between any two stations on the network, and provide backup
links which automatically take over when a primary link goes down.
