Thanks Mitchell,
I did test them individually and they came up fine - I also have another MLX
talking to a CES using a 2 x 1GE LAG just fine (with 5.4c on the CES and 5.4B
on the MLX). I pulled this one apart and turned it into a static LAG which
worked. Our local Brocade folks will try and recreate this in the lab next
week.
Thanks all for the responses!
