Specifying the MST Configuration Revision Number

You configure the revision number on the bridge. For two or more bridges to be in the same MST region,

they must have the identical MST name, VLAN-to-instance mapping, and MST revision number.

Procedure

PurposeCommand or Action

Enters configuration mode.switch# configure terminal

Step 1

Enters MST configuration submode.switch(config)# spanning-tree mst

configuration

Step 2

Specifies the revision number for the MST region.

The range is from 0 to 65535, and the default

value is 0.

switch(config-mst)# revision version

Step 3

This example shows how to configure the revision number of the MSTI region for 5:

switch# configure terminal

switch(config)# spanning-tree mst configuration

switch(config-mst)# revision 5

Specifying the Configuration on an MST Region

For two or more switches to be in the same MST region, they must have the same VLAN-to-instance mapping,

the same configuration revision number, and the same MST name.

A region can have one member or multiple members with the same MST configuration; each member must

be capable of processing IEEE 802.1w RSTP BPDUs. There is no limit to the number of MST regions in a

network, but each region can support only up to 65 MST instances. You can assign a VLAN to only one MST

instance at a time.

Procedure

PurposeCommand or Action

Enters configuration mode.switch# configure terminal

Step 1

Enters MST configuration submode.switch(config)# spanning-tree

mst configuration

Step 2

Maps VLANs to an MST instance as follows:switch(config-mst)# instance

instance-id vlan vlan-range

Step 3

•

For instance-id , the range is from 1 to 4094.

•

For vlan vlan-range , the range is from 1 to 4094.
