Description The ID of a bridge port comprises port priority and port number.
When the path costs of all ports on a bridge are the same, the one with the lowest
port ID is more likely to be elected as the designated port. The process is as follows:
■ Compare the priorities of the ports on the bridge. The one with the lowest port
priority is elected as the designated port.
■ In case multiple ports on the bridge have the same priority, compare their port
numbers and elect the port with the lowest number as the designated port.
To identify the number of each port, execute the display bridge spanning
tree
command.
