VIP-NET-M28A Network Switch - USER MANUAL
VERSION 1.0
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.
