Label Description
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.

4.5 Fast Recovery
Fast recovery mode can be set to connect multiple ports to one or more switches. IGPS-9084GP with fast recovery mode will pro-
vide redundant links. Fast recovery mode supports 12 priorities. Only the first priority will be the active port, and the other ports
with different priorities will be backup ports.
