Item
Controls whether the operEdge flag should start as set or cleared. (The initial
AdminEdge
operEdge state when a port is initialized).
Controls whether the bridge should enable automatic edge detection on the bridge
AutoEdge
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 is selected as an
Alternate Port after the Root Port has been selected. If set, it can cause lack of
Restricted Role
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
Restricted
learned station location information. It is set by a network administrator to prevent
TCN
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.
BPDU Guard
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 to a shared
medium. This can be automatically determined, or forced either true or false.
Point-to-Point
Transition to the forwarding state is faster for point-to-point LANs than for shared
media.
