MST priority is used in selecting the root bridge and alternate bridge of

the specified instance. The device with the highest priority (i.e., lowest

numerical value) becomes the MSTI root device. However, if all devices

have the same priority, the device with the lowest MAC address will

then become the root device.

You can set this switch to act as the MSTI root device by specifying a

priority of 0, or as the MSTI alternate device by specifying a priority of

16384.
