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 ethernet 1/5
Console(config-if)#spanning-tree mst 1 cost 50
Console(config-if)#
Console(config)#interface ethernet ethernet 1/5
Console(config-if)#spanning-tree mst 1 port-priority 0
Console(config-if)#
