4.17.7 MSTI Port Configuration
This section 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.
By clicking on Get we get the below display for the selected MSTI
Figure 4-134: MSTI Port Configuration
Table 4-128: MSTI Port Configuration Parameters
The switch port number of the corresponding STP CIST (and MSTI) port.
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.
Controls the port priority.
This can be used to control priority of ports having identical port cost. (See above).
Get: Click to retrieve settings for a specific MSTI.
Save: Click to save changes
Reset: Click to undo any changes made locally and revert to previously saved values.
