Chapter 7 Advanced Configuration for Compex SGX3226

7.1.2STP Bridge

Spanning-Tree Protocol defines a tree that spans all switches in an extended network. It forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.

Spanning-Tree Protocol operation is transparent to end stations, which are unaware whether they are connected to a single LAN segment or a switched LAN of multiple segments.

This section shows how configuration is done in Spanning Tree parameters.
