Defining Multiple STP

Multiple Spanning Tree (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. The Multiple STP Properties Page contains information for defining global MSTP settings, including region names, MSTP revisions, and maximum hops.

To define MSTP:

1.Click Layer 2 > Multiple STP > Properties. The Multiple STP Properties Page opens:

Figure 70. Multiple STP Properties Page

The Multiple STP Properties Page contains the following fields:

Region Name User-defined STP region name.

Revision — An unsigned 16-bit number that identifies the revision of the current MSTP configuration. The revision number is required as part of the MSTP configuration. The possible field range is 0-65535.

Max Hops — Specifies the total number of hops that occur in a specific region before the BPDU is discarded. Once the BPDU is discarded, the port information is aged out. The possible field range is 1-40. The field default is 20 hops.

IST Master — Identifies the Spanning Tree Master instance. The IST Master is the specified instance root. The IST Master identifies the Bridge priority and the MAC address.

2.Define the relevant fields.
