Configuring Multiple Spanning Tree

Multiple Spanning Tree Protocol

(MSTP) provides differing load balancing scenarios. For example, while port A is

blocked in one STP instance, the same port can be placed in the

Forwarding

state

in another STP instance.

This section contains the following topics:

•

Defining MSTP Properties

•

Defining MSTP Interfaces

•

Defining MSTP Instance Mappings

•

Defining MSTP Instance Settings

Defining MSTP Properties

The

MSTP Page

contains information for defining global MSTP settings, including region names, MSTP revisions,

and maximum hops.

To define MSTP:

Click

Layer 2 > MSTP

. The

MSTP Page

opens:
