Usage Guidelines
You can assign higher priority values (lower numerical values) to interfaces that you want selected first
and lower priority values (higher numerical values) that you want selected last. If all interfaces have the
same priority value, the multiple spanning tree (MST) puts the interface with the lowest interface number
in the forwarding state and blocks other interfaces.

instance-id
Range of spanning-tree instances. You can specify a single instance, a range of
instances separated by a hyphen, or a series of instances separated by a comma. The
range is 0 to 4094.
instances separated by a hyphen, or a series of instances separated by a comma. The
