Spanning Tree | CIST Ports
AdminEdge
Controls whether the
operEdge
flag should start as set or cleared. (The initial
operEdge
state when a port is initialized).
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 is 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.
