no spanning-tree mst instance_id port-priority
• instance_id - Instance identifier of the spanning tree.
(Range: 1-4094, no leading zeroes)
• priority - Priority for an interface. (Range: 0-240 in steps of 16)

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.
