Command Usage
This command defines the priority for the use of an interfa ce in the mul tiple
spanning-tree. If the path cost for all interf ac es o n a swit ch are the sa m e, t he
interface with the highest priority (that is, lowest value) will be con figured as
an active link in the spanning tree.
Where more than one interface is assigned the highes t priorit y, the interfa ce
with lowest numeric identifier will be enabled.
