MST ID. Specify the ID of the MST to create. Valid values for this are between 1 and 
4094.

Priority. Specifiy 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 is set to 0. The default priority 
is 32768.The valid range is 0–61440.

unselected for reconfiguring the association of VLANs to MST instances.
