By default, port priority is 32,768.

After the above configuration, execute the display command in any view to 
display the running of the link aggregation configuration, and to verify the effect 
of the configuration.

In user view, execute the reset command to clear statistics on the LACP-enabled 
port, and the debugging command to enable LACP debugging.

Switch A connects switch B with three aggregation ports, numbered as 
Ethernet2/1/1 to Ethernet2/1/3, so that incoming/outgoing load can be balanced 
among the member ports.
