We want to use these cards for a TAP solution. The traffic is captured through passive optical splitters connected to several 10G links. From the splitters the traffic is then forwarded via a breakout cable to the XL710-QDA2 card. We are interested only in received traffic. Is there a way to capture the traffic on both 40G ports using breakout cables on all 2x4x10G or 2x40G mode in order to use all physical links (8x10G or 2x40G)? I know that on 40G ports there is a 66B encoding and the frames are sent in round robin on the 4 pairs of fiber of the MPO connector. But is it possible to implement in software a method such that to bypass this encoding and capture the traffic on 4x10G breakout on each of the 2 40G ports while the card is in 2x40G mode (thus avoiding the 4 MACs limitation)?
