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.
Example
ecn330(config)# ecn port 1 spanning-tree port-priority 0
