While Classic STP prevents 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. The Global System LAG 
information displays the same field information as the ports, but represents the LAG RSTP 
information.

To define RSTP on the device:

1. Click Switching > STP > Advanced > RSTP. The Rapid STP screen displays:

The Rapid STP screen contains the following fields:

•

Interface – Displays the port or LAG on which Rapid STP is enabled.

•

Role – Displays the port role assigned by the STP algorithm to provide to STP paths. The 
possible field values are:

–

Root – Provides the lowest cost path to forward packets to the root switch.

–

Designated – The port or LAG through which the designated switch is attached to the 
LAN.

–

Alternate – Provides an alternate path to the root switch from the root interface.
