May be packet fields (traffic from TRex) associated with pipe, tc, and queues are not randomized, so traffic is only going to specific scheduler queues. Please refer documentation to know offsets of packet fields.

But it only can pass 1Mbps. Why? And I set the subport 0 speed limit of 200 Kbps, it can pass about 666 Kbps, why? Has anyone helped explain why speed limits are ineffective? Subport 0: Rate = 200000 bytes/second Token bucket size = 1000000 bytes Traffic class rate: TC0 = 200000, TC1 = 200000, TC2 = 200000, TC3 = 200000 bytes/second TC period = 10 milliseconds Total-Tx : 20.02 Mbps Total-Rx : 667.15 Kbps
