I tried Pagp, Lacp and the only thing I didnt try was "mode on". I am not attempting VSS but I was only attempting to create a simple portchannel trunk between the distribution pair. The portchannel didnt want to bundle with no matter what I did on the config and I am perplexed what I am forgetting or do not know. Please help.
