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 se t, 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.
Point-to-Point
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.
