MST Port Configuration
Use the MST Port Configuration screen to configure and display Multiple Spanning Tree
(MST) settings on a specific port on the switch.
To configure MST port settings:
1. Select Switching STP Advanced MST Port Configuration.
The following screen displays:
Note: If no MST instances have been configured on the switch, the screen
displays a “No MSTs Available” message.
2. To view CST settings for an interface, click PORTS, LAGS, or All.
3. Select the check box next to the port or LAG to configure.
You can select multiple ports and LAGs to apply the same setting to the selected
interfaces. Select the check box in the heading row to apply the same settings to all
interfaces.
4. Configure the MST values for the selected ports or LAGs:
•Port Priority. The priority for a particular port within the selected MST instance. The
port priority is set in multiples of 16. If you specify a value that is not a multiple of 16,
the priority is automatically set to the next lowest priority that is a multiple of 16. For
example, if you set a value from 0 through 15, the priority is set to 0. If you specify a
number from 16 through 31, the priority is set to 16. The valid range is 0–240.
•Port Path Cost. Set the path cost to a new value for the specified port in the selected
MST instance. The valid range is 0–200000000. If you enter 0, the device
recalculates the path cost.
