Spanning Tree Protocol - Bay Networks BayStack 303 User Manual

The BayStack 303 switch can be used as a desktop switch to provide 100 Mb/s
connections to the server and network center and to give dedicated 10 Mb/s
connections to up to 23 users instead of shared 10 Mb/s connections (see

Spanning Tree Protocol

The Spanning Tree Protocol is a technique based on the IEEE 802.1d standard that
detects and eliminates logical loops in a bridged or switched network. When
multiple paths exist, the Spanning Tree Algorithm configures the network so that a
bridge/switch uses only the most efficient path. If that path fails, the protocol
automatically reconfigures the network to make another path become active,
sustaining network operations.
