Configuring 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. When network topology allows, faster convergence may be possible. The
Rapid Spanning Tree Protocol (RSTP) detects and uses of network topologies that provide faster
convergence of the spanning tree, without creating forwarding loops.
RSTP has the following different port states:
• Disabled
• Learning
• Discarding
• Forwarding
Rapid Spanning Tree is enabled on the STP Global Settings page. To open the Rapid Spanning
Tree (RSTP) page, click Switch Spanning Tree Rapid Spanning Tree in the tree view.
