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. (See above).
