Hi. I am tried to add another traffic class to the showcase by updating relevant parameters such as source, sink apps, another class type and mac queue object etc. However, it is not working. The sub queue for the third class is not containing any packets and the gate and transmission statistics are also not being updated. I can share the code if you want. Any suggestions?

I am struggling with the same issue. Did you already find a solution?

[ahmed3009]

Yes. Look closely at the pcp values. They need to be set as IEEE standard. https://en.wikipedia.org/wiki/IEEE_P802.1p for reference

Thank for the hint! But finally the mapping Table 8-5 "Recommended priority to traffic class mappings" in the IEEE802.1Q-2018 has led me to the solution

I also encountered the same problem, after I added the audio stream, the audio stream has no data and no histogram, how did you solve it

[ahmed3009]

@paixingxing-1 As mentioned above, you need to look at the PCP values (Table 8-5 "Recommended priority to traffic class mappings") of the classes that you are setting. If they are incorrect, all audio stream packets will continue to go to the same video stream class.

Yes I used the same resource. I just couldn't remember the link to the table you mentioned.
