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.
