Command Usage
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.
