RSTP Port Settings
While the classic spanning tree prevents Layer 2 forwarding loops in a general
network topology, convergence can take between 30-60 seconds. This time may
delay detecting possible loops, and propagating status topology changes. Rapid
Spanning Tree Protocol (RSTP) detects and uses network topologies that allow a
faster STP convergence without creating forwarding loops.
To define RSTP on interfaces:
STEP 1 Click Spanning Tree > RSTP Port Settings. The RSTP Port Settings Screen opens.
