Spanning Tree -> Rapid Spanning Tree
While Classic Spanning Tree guarantees preventing L2 forwarding loops in a general network
topology, convergence can take up to 30-60 seconds. The convergence time is considered too long
for many applications. Faster convergence can often be obtained by using the Rapid Spanning Tree
Protocol (RSTP).
RSTP has the following different port states: Disabled, Learning, Discarding, and Forwarding. You
can enable Rapid Spanning Tree is enabled on the STP Global Settings page.
