The switch port number of the logical STP port.
Controls whether STP is enabled on this switch 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).
Operational flag describing whether the port is connecting directly to edge devices.
(No Bridges attached). Transition to the forwarding state is faster for edge ports
(having operEdge true) than for other ports. The value of this flag is based on
AdminEdge and AutoEdge fields. This flag is displayed as Edge in Monitor->Spanning
Tree -> STP Detailed Bridge Status.
Controls whether the operEdge flag should start as set or cleared. (The initial
operEdge state when a port is initialized).
Controls whether the bridge should enable automatic edge detection on the bridge
CIST port configurations, and possibly change them as
ports.
