Multiple Spanning Tree Protocol (MSTP) is used in various 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. The
Properties
page enables you to define the global MSTP settings.
To configure MSTP:
1. Set the STP Operation Mode to MSTP as described in the
Status and Global Settings
2. Define MSTP instances. Each MSTP instance calculates and builds a loop free
topology to bridge packets from the VLANs that map to the instance. Refer to
the Mapping VLANs to a MSTP Instance
3. Decide which MSTP instance will be active in what VLAN, and associate these
MSTP instances to VLAN(s) accordingly.
4. Configure the MSTP attributes by:
• Defining MSTP Properties
• Defining MSTP Instance Settings
—The port is in Forwarding mode. The port can forward
