Description
The switch port number of the corresponding STP CIST (and MSTI) port.
Controls the path cost incurred by the port. The Auto setting will set the path cost
as appropriate by the physical link speed, using the 802.1D recommended
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.
Controls the port priority. This can be used to control priority of ports having
identical port cost.
