◆ 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.
