Description
The switch port number of the logical STP port.
Controls whether RSTP is enabled on this switch port,
of Managed Switch.
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. All means all ports will have one
specific setting.
Controls the port priority. This can be used to control priority of ports having
identical port cost. (See above).
Default: 128
Range: 0-240, in steps of 16
All means all ports will have one specific setting.
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 beeing set or cleared. (The
initial operEdge state when a port is initialized). All means all ports will have one
specific setting.
Controls whether the bridge should enable automatic edge detection on the
bridge port. This allows operEdge to be derived from whether BPDU's are
received on the port or not.
If enabled, causes the port not to be selected as Root Port for the CIST or any
MSTI, even if it has the best spanning tree priority vector. Such a port will be
selected as an Alternate Port after the Root Port has been selected. If set, it can
cause lack of spanning tree connectivity. It can be set by a network administrator
to prevent bridges external to a core region of the network influence the spanning
tree active topology, possibly because those bridges are not under the full control
of the administrator. This feature is also known as Root Guard.
If enabled, causes the port not to propagate received topology change
notifications and topology changes to other ports. If set it can cause temporary
loss of connectivity after changes in a spanning tree's active topology as a result
of persistently incorrect learned station location information. It is set by a network
