The Chassis/Fex discovery policy now has a backplane speed selection option, 40G or 4x10G. I assume this coresponds to the breakout port function, but I have not found any good guidance on this as of yet. What is the function of this selection? When should it be configured? Is it the case that if you intend to use the breakout function on the 40G ports, you must set the backplane speed to 4x10G and no longer have 40G connectivity available?
Thanks,
Mark
