Controls whether the operEdge flag should start as being set or cleared. (The
initial operEdge state when a port is initialized).
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 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.
