Description
Select port number for this drop down list.
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 whether the operEdge flag should start as beeing set or cleared. (The initial
operEdge state when a port is initialized).
Control whether a port explicitly configured as Edge will transmit and receive BPDUs.
Control whether a port explicitly configured as Edge will disable itself upon reception of a
BPDU.
The port will enter the error-disabled state, and will be removed from the active topology.
Controls whether the port connects to a point-to-point LAN rather than a shared medium.
This can be automatically determined, or forced either true or false. Transition to the
forwarding state is faster for point-to-point LANs than for shared media.
(This applies to physical ports only. Aggregations are always forced Point2Point).
If at any time the switch detects STP BPDUs, including Configuration or Topology Change
Notification BPDUs, it will automatically set the selected interface to forced STP-compatible
mode.
However, you can also use the Protocol Migration button to manually re-check the
appropriate BPDU format (RSTP or STP-compatible) to send on the selected interfaces.
