Event ID 16713 — Advanced QoS Settings

  • Article

Applies To: Windows Server 2008

Advanced Quality of Service (QoS) settings provide additional controls for IT administrators to manage computer network use and DSCP markings. Advanced QoS settings apply only at the computer level, whereas QoS policies can be applied at both the computer and user levels.

Event Details

Product: Windows Operating System
ID: 16713
Source: Tcpip
Version: 6.0
Symbolic Name: EVENT_EQOS_ERROR_SETTING_APP_MARKING
Message: QoS failed to read or set the DSCP marking override setting, error code: "%2".

Resolve

Correct DSCP marking override setting

DSCP marking override restricts the ability of applications to specify, or "mark," DSCP values other than those specified in QoS policies. By specifying that applications are allowed to set DSCP values, applications can set non-zero DSCP values. By specifying Ignored, applications that use QoS application programming interfaces (APIs) will have their DSCP values set to zero, and only QoS policies can set DSCP values. By default, computers running Windows Vista and Windows Server 2008 allow applications to specify DSCP values; applications and devices that do not use the QoS APIs are not overridden.

You must be logged on as an administrator or belong to the Administrators group to complete this procedure.

To set DSCP marking override:

  1. Click Start, point to All Programs, click Accessories, right-click Command Prompt, click Run as administrator, click Continue, type gpedit, and then press ENTER.
  2. In Group Policy Management Editor, click Local Computer Policy, click Windows Settings, right-click Policy-based QoS, and then click Advanced QoS Settings.
  3. In DSCP marking override, select Allowed or Ignored according to your policy preference, and then click OK.

Note: You can use Group Policy Management Console to change these settings on more than one computer.
