MSTP Overview

MSTP maps VLANs into STP instances, using various load balancing

scenarios. As a result of this partitioning into instances, if port A is blocked in

one STP instance, the same port can be placed in the Forwarding State in

another STP instance.
In addition, packets assigned to various VLANs are transmitted along

different paths within Multiple Spanning Trees Regions (MST Regions).

Regions are one or more Multiple Spanning Tree bridges by which frames can

be transmitted.

1 Click Switching > Spanning Tree > MSTP Properties in the tree view to

Region Name (1-32 Characters) — Enter the user-defined MSTP

region name.
