STP MSTI Port Configuration
Click the Edit button to display the STP MSTI Port Configuration page.
This page lets you view and configure the current STP MSTI port configurations.
An MSTI port is a virtual port, which is instantiated separately for each active CIST (physical) port for each MSTI
instance configured on and applicable to 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.
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 1 ‐ 200000000.
