AdminEdge
Configures the operEdge flag to start as set or cleared.(the initial
operEdge state when a port is initialized).
AutoEdge
Check to enable the bridge to detect edges at the bridge port
automatically. This allows
operEdge
to be derived from whether BPDUs
are received on the port or not.
Restricted Role
When enabled, the port will not be selected as root port for 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, spanning trees will lose connectivity. It can be set by a
network administrator to prevent bridges outside a core region of the
network from influencing the active spanning tree topology because
those bridges are not under the full control of the administrator. This
feature is also known as Root Guard.
Restricted TCN
When enabled, the port will not propagate received topology change
notifications and topology changes to other ports. If set, it will cause
temporary disconnection after changes in an active spanning trees
topology as a result of persistent incorrectly learned station location
information. It is set by a network administrator to prevent bridges
outside a core region of the network from causing address flushing in
that region because those bridges are not under the full control of the
administrator or is the physical link state for the attached LANs
transitions frequently.
Point2Point
Configures whether the port connects to a point-to-point LAN rather than
a shared medium. This can be configured automatically or set to true or
false manually. Transiting to forwarding state is faster for point-to-point
LANs than for shared media.

values.
4.5 Fast Recovery
Fast recovery mode can be set to connect multiple ports to one or more switches. The device
with fast recovery mode will provide redundant links. Fast recovery mode supports 24 priorities.
Only the first priority will be the active port, and the other ports with different priorities will be
backup ports.
