Soku, Maybe there was a misunderstanding , the inbound traffic on fpc2's LAG was 4Gbps , and the outbound traffic was 27Gbps aprox. That outbound traffic enters by the fpc1 and fpc0. It's IMIX traffic, the average packet size is 1250Bytes (out) 200Bytes (in). I tried to see dropped packets with "show precl-eng 5 statistics " and "show mqchip 0 drop stats" at pfe shell but it's 0. Does it save historical data?
