Provide as much detail as you can - if you're using hw flow control, whether both links act this way at the same time or independently, and so-on. Problems like this often boil down to a very small and seemingly insignificant detail. I currently have ixgbe on the operating table for adding X550 support, so I can take a look at this; however I don't have your type of switches available to me so LACP-specific testing is something I can't do for you. /dale
