Rapid Spanning Tree

While classic spanning tree prevents Layer 2 forwarding loops on a general
network topology, convergence can take from 30 to 60 seconds. This delay
provides time to detect possible loops, and propagate status changes.
Rapid Spanning Tree Protocol (RSTP) detects and uses network topologies
that enable a faster convergence of the spanning tree, without creating
forwarding loops.
To configure RSTP:
1 Click Switching > Spanning Tree > Rapid Spanning Tree in the tree view
to display the Rapid Spanning Tree: Summary page.
