Parameter 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

ports. Valid values are in the range 1 to 200000000.
