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.
Label
Description
Port
The switch port number of the corresponding STP CIST (and MSTI) port.
Path Cost
Controls the path cost incurred by the port. The Auto setting will set the path cost as
appropriate by the physical link speed, using the 802.1D recommended values. Using
the Specific setting, a user-defined value can be entered. The path cost is used when
establishing the active topology of the network. Lower path cost ports are chosen as
forwarding ports in favor of higher path cost ports. Valid values are in the range 1 to
200000000.
Priority
Controls the port priority. This can be used to control priority of ports having identical
port cost. (See above).
