cleared. (The initial operEdge state when a port is
initialized).
Auto Edge 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 affect 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.
After finished the above settings, click Apply to save the configuration. The settings will
take effect.
