I am trying to set QoS values on an MX200 endpoint to AF41 (decimal 34) for audio/video packets. I entered the values in the GUI and it saved OK. A sniffer trace shows the packets still marked as Best Effort DSCP=0. I tried a system restart from the maintenance tab but no help. Command line seems to show the correct values:
*c xConfiguration Network 1 QoS Mode: Diffserv
*c xConfiguration Network 1 QoS Diffserv Audio: 34
*c xConfiguration Network 1 QoS Diffserv Data: 22
*c xConfiguration Network 1 QoS Diffserv Signalling: 26
*c xConfiguration Network 1 QoS Diffserv Video: 34
- Software version:TC18.104.22.1680662
Anybody run into this issue?

Have you verified that the switchport is trusting DSCP?
That's where I'd look first; a switch that has QoS activated, but is not configured to Trust DSCP from the codec port, will remark all packets as DSCP 0.
