Command Usage
This command defines the priority for the use of a port in the
Spanning Tree Algorithm. If the path cost for all ports on a switch are
the same, the port with the highest priority (that is, lowest value) will
be configured as an active link in the spanning tree.
Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled.
