Defining Rapid
Spanning Tree
While Classic STP 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.
The Global System LAG information displays the same field information
as the ports, but represent the LAG RSTP information.

The
RSTP Summary Page
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.
