Ingress DSCP marking isn't supported on EX4200.

You need to classify (into a FC) on ingress, and rewrite on egress. You can
use a simple fixed classifier on ingress but packet marking/rewrite is only
performed on egress.

Example of a fixed classifier:

# set class-of-service interfaces ge-0/1/0 unit 0 forwarding-class
