Spanning Tree Protocol and Configuration
The
♦Network loop detection and prevention. There should only be one path between any two stations on the network. If there is more than one path, packets will be forwarded in loops forever. The spanning tree protocol detects any looping paths, and selects the path with the lowest path cost as the active path, while blocking other paths and using them as backups.
♦Automatic topology reconfiguration. If a path for which there is a backup path fails, the backup path will be automatically activated, and the spanning tree protocol will automatically reconfigure the network topology.
STP parameters are mainly used to determine the root bridge and root ports on the network. If there is a loop in the network, data packets will go through the root bridge. If the bridge has several ports, then the root port will be used to pass data packets to the root bridge.
STP settings are complex, so you probably want to leave these default parameter values as they are. If you really need to modify their values, please refer to the following discussion.
