DiffServ markings not applied

I’m using a virtual Spirent with a couple of chassis. I’ve created a very simple network, with a few devices and I’m generating bidirectional traffic between them. Traffic flows fine, but if I enable Diffserv markings as AF11, then I’m only seeing the traffic marked in one direction. In the other direction it is coming through as CS0, even though the configuration looks fine.

Both Chassis are running 5.11.9366 firmware with the stc test package, and both are using dpdk. I;m stumped. Any ideas?

To provide an update, the issue was not Spirent, its the configuration of our network. It was meant to be configured for Short-Pipe, and it was not. Fixing that obviously resolved the issue.
