values. Using the Specific setting, a user-defined value can be entered. The
path cost is used when establishing the active topology of the network. Lower
path cost ports are chosen as forwarding ports in favor of higher path cost
ports. Valid values are in the range 1 to 200000000.

identical port cost. (See above).
