Edge server QoS RRS feed

  • Question

  • Hi,

    we want to enable QoS on Edge server,  Since our internet broadband is limited.

    we did try some change on the servers, but got no luck.

    the DSCP value still 0 as below:

    we already set the DSCP on client site (lync client) via group policy. But the edge server's dscp value still 0.

    btw, in our router, we did set :

    class-map Voice
     match dscp ef


    we want to know what value need to set on skype server site in this case? 46 ?

    we want to make all skype traffic via edge have QoS, no matter audio or video..

    thanks !!!!

  • Hi Jerry,

    For the Audio Policy, you need to set the DSCP value to 46, and for the Video Policy, you need to set the value to 34 (you do not have to use a DSCP value of 34. The only requirement is that you use a different DSCP value for video than you used for audio). About this, you could refer to the official document to find more details about Configuring a Quality of Service policy for your A/V Edge Server.

    In addition, you could refer to the following blog to find more details about the DSCP value and the port ranges. 

    Best Regards,
