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
the lowest numeric identifier will be enabled.
