create switch trunk=name port=ports
[select=macsrc|macboth]
Parameters
trunk Specifies the name of the trunk. The name can be up
to 10 alphanumeric characters. No spaces or special

port Specifies the ports of the trunk. A trunk can have up

select Specifies the load distribution method. Options are:

ports of the trunk and the load distribution method.
