MST Configuration.

To configure an MST instance:

To add an MST instance, configure the MST values and click Add:

MST ID - Specify the ID of the MST to create. Valid values for this are between 1 and 
4094. This is only visible when the select option of the MST ID select box is selected.

Priority - Specifies the bridge priority value for the MST. When switches or bridges 

are running STP, each is assigned a priority. After exchanging BPDUs, the switch with 
the lowest priority value becomes the root bridge. The bridge priority is a multiple of 
4096. If you specify a priority that is not a multiple of 4096, the priority is automatically 
set to the next lowest priority that is a multiple of 4096. For example, if the priority is 
attempted to be set to any value between 0 and 4095, it will be set to 0. The default 
priority is 32768.The valid range is 0–61440.

VLAN ID - This gives a combo box of each VLAN on the switch. These can be 

selected or unselected for re-configuring the association of VLANs to MST instances.

To delete an MST instance, select the check box next to the instance and click Delete.

To modify an MST instance, select the check box next to the instance to configure, update 
the values, and click Apply. You can select multiple check boxes to apply the same setting 
to all selected ports.

Click Cancel to cancel the configuration on the screen and reset the data on the screen to 
the latest value of the switch.
