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
SSE-G2252(config)#interface Ethernet 1/5
SSE-G2252(config-if)#spanning-tree mst 1 port-priority 0
SSE-G2252(config-if)#
