ExtremeXOS supports rapid root failover for faster STP (Spanning Tree Protocol) failover recovery times in STP 802.1D mode. If the active root port link goes down, ExtremeXOS recalculates STP and elects a new root port. The rapid root failover feature allows the new root port to immediately begin forwarding, skipping the standard listening and learning phases. Rapid root failover occurs only when the link goes down and not when there is any other root port failure, such as missing BPDUs.
The default setting for this feature is disabled.
