Command Usage
• This command defines the priority for the use of an interface in the multiple spanning-tree. If
the path cost for all interfaces on a switch are the same, the interface with the highest priority
(that is, lowest value) will be configured as an active link in the spanning tree.
• Where more than one interface is assigned the highest priority, the interface with lowest
numeric identifier will be enabled.
Example
Console(config)#interface Ethernet 1/5
Console(config-if)#spanning-tree mst 1 port-priority 0
