Product and Software: This article applies to Aruba controllers except 800 and 200 and to ArubaOS 3.4 and later. Yes, a LACP configuration automatically inherits the properties of a port channel. Set up the port channel first so that when you add the interfaces they are configured as you want them in the port channel. Either way, when you aggregate any ports, Aruba recommends that you use the serial port of the controller to do the configuration, just in case you make an error. Here is a snippet of LACP configuration (not necessarily in order):
