For layer 2 make sure the trunking encapsulation is the same on the
interfaces in the group and the port-channelx interface. Make sure that the
lacp/pagp modes are compatible on the physical interfaces. I'm sure that
someone has a better method, but I'd start by making sure the trunks on the
physical interfaces come up first. Then create the etherchannel.
