MST Configuration

For MST to work between two switches the following has to be the same:

1. Name
2. Revision Number
3. Instance to VLAN Mapping

Switch(config)# spanning-tree mode mst

Switch(config)# spanning-tree mst configuration

Switch(config-mst)# name <instance-name>

Switch(config-mst)# revision <revision-number>

Switch(config-mst)# instance <instance-id> vlan <vlan-list>

Switch(config)# spanning-tree mst <instance-id> root [primary | secondary] diameter <diameter>

Switch(config)# spanning-tree mst <instance-id> priority <bridge-priority>

Switch(config-if)# spanning-tree mst <instance-id> cost <cost>

Switch(config-if)# spanning-tree mst <instance-id> port-priority <port-priority>

Switch(config)# spanning-tree mst <instance-id> mst hello-time <seconds>

Switch(config)# spanning-tree mst <instance-id> mst forward-time <seconds>

Switch(config)# spanning-tree mst <instance-id> mst max-age <seconds>
