This command defines the priority for the use of an interface in the

multiple spanning-tree. If the path cost for all interfaces on a switch are

the same, the interface with the highest priority (that is, lowest value)

will be configured as an active link in the spanning tree.

Where more than one interface is assigned the highest priority, the

interface with lowest numeric identifier will be enabled.
