Microsoft Teams QOS : Enabling Windows DSCP Marking in Wireshark Tool

Hello All

Hope everyone is doing good 

In the below article,  we saw the how to implement  Quality of Service (QoS) in Microsoft Teams and Troubleshooting process using NETMON tool

 https://cloudmonkeys20.blogspot.com/2024/01/quality-of-service-qos-in-microsoft.html

However this article, will talks about the same process of QOS implementation  and do the troubleshooting with wireshark tool this time


Both netmon and wireshark are  networking tool to analyse the network traffic and Packets

Open Wireshark, first we need to add DSCP to the columns.  So right click on the column and select “Column Preferences”



Click on the “+” button at the bottom and this creates a new field.  Add the following

  • Double click the name filed and call DSCP
  • Change the Type to “Custom”
  • Double click the name field and type ip.dsfield.dscp
  • Field occurrence = 0

Select “ok”


Make sure you can see the “DSCP” in the columns



I hope , this would be helpful to someone who use wireshark tool for MS Teams QOS troubleshooting. Happy Learning 😃
