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 influencing the spanning tree active topology, possibly because
those bridges are not under the full control of the administrator. This
feature is also know 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 trees active
topology as a result of persistent incorrectly 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 is the physical link state for the attached LANs transitions
frequently.
Point2Point
Controls whether the port connects to a point-to-point LAN rather than 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.

MSTI Ports
This page allows the user to inspect the current STP MSTI port configurations, and possibly change them as well. A
MSTI port is a virtual port, which is instantiated separately for each active CIST (physical) port for each MSTI
instance configured and applicable for the port. The MSTI instance must be selected before displaying actual MSTI
port configuration options.
This page contains MSTI port settings for physical and aggregated ports. The aggregation settings are stack global.
