path-cost
Specifies the cost of a port to the root bridge. The range is 1 to

Description
Use this command to specify the cost of a port to the root bridge. This cost
is combined with the costs of the other ports in the path to the root bridge,
to determine the total path cost. For MSTP, this command only applies to
the path cost for CIST. The lower the numeric value, the higher the priority
of a path. The range is 1 to 200000000. The default depends on the port
speed.
To return a port to the default value, use the no version of this command,
NO SPANNING-TREE PATH-COST.
