Quality of Service (QoS) DSCP Marking is used to determine traffic classification for network data. This can be used to determine which network traffic requires higher bandwidth, has a higher priority, and more likely to drop packets.
The default Zoom DSCP marking values are 56 for audio, 40 for video, and 40 for signaling. You can update audio and video values to allow a network administrator to adjust the priority for Zoom traffic on their network.
Note: For the Zoom desktop client and Zoom Rooms for PC, you must run Zoom as an administrator to support custom DSCP markings.
If your organization deploys Zoom via an MSI installation, the MSI must be re-deployed after configuring the DSCP markings. If the DSCP markings are ever changed, the MSI will need to be re-deployed.
To enable and configure the DSCP marking values for all members of your organization:
- Sign into the Zoom web portal as an administrator with the privilege to edit Account settings, and click Account Settings.
- Navigate to the In Meeting (Advanced) options on the Meeting tab and verify that the setting is enabled.
If the setting is disabled, click the Status toggle to enable it. If a verification dialog displays, choose Turn On to verify the change.
- (Optional) If you want to make this setting mandatory for all users in your account, click the lock icon, and then click Lock to confirm the setting.
