Use the no form of this command to revert to the default setting. spanning-tree mst INSTANCE-ID {cost COST | port-priority PRIORITY} no spanning-tree mst INSTANCE-ID {cost | port-priority} Parameters INSTANCE-ID cost COST port-priority PRIORITY Specifies the MSTP instance identifier. Specifies the path cost for an instance. This value must be between 1 and 200000000. Specifies the port priority for an instance. This value must be between 0 and 240 in increments of 16. Default The cost is defined based on the port speed. The faster the speed is, the smaller cost value it is. MST always uses long path cost. The port priority is 128. 321
