Description
The switch port number of the logical STP port.
Controls if RSTP is enabled on this switch port.
Controls the path cost incurred by the port. The
path cost as appropriate by the physical link speed, using the 802.1D
recommended values. Using the
value can be entered. The path cost is used when establishing the
active topology of the network. Lower path cost ports can be chosen
as forwarding ports in favor of higher path cost ports. Valid values are
in the range of 1 to 200000000.
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
Controls whether the operEdge flag should start as set or cleared (the
initial operEdge state when a port is initialized).
Controls if the bridge should enable automatic edge detection on the
bridge port. This allows operEdge to be derived from BPDUs received
on the port.
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 a lack of spanning tree
connectivity. It can be set by a network administrator to prevent
bridges external to a core region of the network and 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 administrator to
prevent bridges external to a core region of the network, causing
address flushing in that region, possibly because those bridges are
not under the full control of the administrator or the physical link state
of the attached LANs transits frequently.
If enabled, causes the port to disable itself upon receiving valid
BPDU's. Contrary to the similar bridge setting, the port Edge status
does not effect this setting.
A port entering error-disabled state due to this setting is subject to the
bridge port error recovery setting as well.
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. Transitions to the forwarding state is faster
for point-to-point LANs than for shared media.
