MST Configuration

Use this command to group VLANs into spanning tree instances. MSTP

generates a unique spanning tree for each instance. This provides

multiple pathways across the network, thereby balancing the traffic

load, preventing wide-scale disruption when a bridge node in a single

instance fails, and allowing for faster convergence of a new topology for

the failed instance.

By default all VLANs are assigned to the Internal Spanning Tree

(MSTI 0) that connects all bridges and LANs within the MST region. This

switch supports up to 32 instances. You should try to group VLANs

which cover the same general area of your network. However,

remember that you must configure all bridges within the same MSTI

instance (on each bridge) with the same set of VLANs. Also, note that

RSTP treats each MSTI region as a single node, connecting all regions

to the Common Spanning Tree.

Console(config-mstp)#mst 1 vlan 2-5

Console(config-mstp)#

This command configures the name for the multiple spanning tree region in

which this switch is located. Use the no form to clear the name.

MST Configuration

The MST region name and revision number

designate a unique MST region. A bridge (i.e., spanning-tree compliant

device such as this switch) can only belong to one MST region. And all

bridges in the same region must be configured with the same MST
