Multiple Instance Spanning-Tree Operation

Overview

The switches covered in this guide, use the IEEE 802.1s Multiple Spanning
Tree Protocol (MSTP) standard.

Parameters
Enabling/Disabling MSTP Spanning Tree
Operation
Enabling an Entire MST Region at Once
Without spanning tree, having more than one active path between a pair of
nodes causes loops in the network, which can result in duplication of mes-
sages, leading to a "broadcast storm" that can bring down the network.
