Thanks for pointing this out.

Is a fixed classifier supported on a vlan interface?

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
best-effort

Cheers,
Dale

[j-nsp] Reset DSCP on ingress (again)

[Victor Sudakov]

Dear Colleagues,

Sorry for repeating the question.

What is the easiest method of resetting the dscp value in incoming
packets when the incoming port is configured for "family ethernet-switching"?

If the port were in "family inet", I would use the firewall, but the
"family ethernet-switching" firewall does not seem to have a means to
set dscp.

Thanks a lot in advance.

The device is EX4200-24T, 12.3R6.6
