DSCP tag is not working on desktop sharing ( Teams - Microsoft )

[Mestapha]

Hello , 

i'm new to this forum so im looking forward to you help, im trying to apply a Qos tag on my desktop sharing traffic .

using traffic shapping rules .

1st  2nd and 3th rule seems to be working fine ( checked via packet capture ) - they're tagging audio, video and screen sharing traffic .

The 4th rule is the one that im having problems with all am seeing is a dscp  cs3 tagged to the IP packets however this tag is not configurd nowhere .

you can see screenshot of my configuration as well as the packet capture .

traffic goes from the user ---> AP----> MX .
caprture taken on the MX ( internet port )

model : MX100

thank you in advanced for you help .

you are matching on destination ip or port. but your wireshark info shows other destination ip and port

Hello ,

thank you for your comment , actually ports from 50040 to 50059 are matching in the third screenshot .

that is the one that im having issue with .

the're showing as CS3 tag but in the traffic shaping rules i configured them to be tagged on AF21.

looking forward to your reply .
