CIST Aggregated/ Normal Port Configuration
Setting Description
Port The switch port number of the logical STP port.
STP Enabled Controls whether STP is enabled on this switch port.
Path Cost
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.
Priority
Controls the port priority. This can be used to control priority of ports having
identical port cost.
