AutoEdge
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.
Restricted Role
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.
Restricted TCN
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.
BPDU Guard
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.
Point-to-Point
Controls whether the port connects to a point-to-point LAN rather than to 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.
