Configure the priority of the switch in the instance.
instance-id
:
Specify the instance ID, the valid values ranges from 1 to 8.
pri
:
Specify the priority of the switch. The valid values are from 0 to 61440, which are divisible
by 4096, and the default value is 32768. The switch with the lower value has the higher
priority, and the switch with the highest priority will be elected as the root bridge in the desired
instance.
