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.
