Figure 3-4.4: The STP CIST Port Configuration
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 (see above).
AdminEdge:
Controls whether the operEdge flag should start as set or cleared (the
initial operEdge state when a port is initialized).
