Spanning Tree Protocol Overview

STP is a bridge-based mechanism for providing fault tolerance on networks.

STP allows you to implement parallel paths for network traffic and to ensure that redundant paths are:

Disabled when the main paths are operational.
Enabled if the main path fails.

Note

STP and ESRP cannot be configured on the same VLAN simultaneously.

Note

If you are transitioning from EOS to ExtremeXOS, please note that ExtremeXOS blocks on a more granular (VLAN) level, instead of at the port level as EOS does.
