What is the purpose of the command "clear trunk 3/13 1006-1023"? I think it prevents those vlans from crossing the trunk but why would you want to eliminate those specific vlans?
Does the order matter? should the "set trunk 3/13 auto negotiate 1-1005,1024-4094" be entered before the "clear trunk 3/13 1006-1023"?
Also do I need to disable portfast on these ports?
Conifguring and testing next week.
Thanks

LACP is IEEE, PAGP is Cisco-proprietary. If it is ON then it doesn't negotiate either protocol. For practical purposes, that's the difference. So if you have a non-Cisco switch and you want to run etherchannel from it, you have to either run LACP or set it to on.
Cisco chooses PAGP by default. I suspect the channel showing up under PAGP is because that's the default protocol for the port if it was negotiating, which it isn't. If that's working now I would just do the same thing again.
