Creating and Editing a QoS Policy

Applies To: Windows 7, Windows Server 2008 R2

To create or edit a QoS policy, use the Group Policy Management Console (GPMC). When you edit a Group Policy object (GPO), you can find QoS policies in Computer Configuration\Policies\Windows Settings or User Configuration\Policies\Windows Settings in the Group Policy Management Editor. QoS policies created in Computer Configuration apply to computers regardless of who is logged on. QoS policies created in User Configuration apply to a user session regardless of the computer being used. For more information, see Windows Server Group Policy (http://go.microsoft.com/fwlink/?LinkID=116313).

When you create a new QoS policy, wizard pages guide you through the policy configuration. When you edit a QoS policy, tabs corresponding to these wizard pages enable you to change settings.

Policy Profile tab (Wizard page 1)

 

Item Details

Policy name

Type a name for the QoS policy that uniquely identifies the policy.

Specify DSCP value

Select the check box to enable DSCP marking, and then type a DSCP value between 0 and 63.

Specify throttle rate

Select the check box to enable throttling for outbound traffic, and then specify a value greater than 1 in either kilobytes per second (KBps) or megabytes per second (MBps).

Application Name or URL tab (Wizard page 2)

 

Item Details

All applications

Default. Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic, regardless of application.

Only applications with this executable name

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic only for the application you specify. The executable file name must end with the .exe file name extension. You can include the path with the application name, and the path can include environment variables (for example, %ProgramFiles%\My Application Path\MyApp.exe or c:\program files\my application path\myapp.exe). The application path cannot include a symbolic link.

Only HTTP server applications responding to requests from this URL

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic that is responding to a specified URL. HTTP and HTTPS URLs are supported. The URL can include wildcard characters and can specify a host name and port number. Select the Include subdirectories and files check box to apply the traffic management settings to all subdirectories and files of the URL.

IP Addresses tab (Wizard page 3)

 

Item Details

Any source IP address

Default. Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic, regardless of the source IP address of the traffic.

Only for the following source IP address or prefix

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic from a source IP address that you specify. You can specify the IP address in any of these formats:

  • An Internet Protocol version 4 (IPv4) address, such as 1.2.3.4. If this address is of link-local scope or is defined by RFC 1918, it must use the prefix length notation.

  • An IPv4 address prefix using network prefix length notation, such as 192.168.1.0/24.

  • An Internet Protocol version 6 (IPv6) address, such as 3ffe:ffff::1. If this address is of link-local scope or site-local scope, it must use the prefix length notation.

  • An IPv6 address prefix, such as fe80::1234/48.

Any destination IP address

Default. Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic, regardless of the source IP address of the traffic.

Only for the following destination IP address or prefix

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic bound for a destination IP address that you specify. You can specify the IP address in any of these formats:

  • An IPv4 address, such as 1.2.3.4. If this address is of link-local scope or is defined by RFC 1918, it must use the prefix length notation.

  • An IPv4 address prefix using network prefix length notation, such as 192.168.1.0/24.

  • An IPv6 address, such as 3ffe:ffff::1. If this address is of link-local scope or site-local scope, it must use the prefix length notation.

  • An IPv6 address prefix, such as fe80::1234/48.

Protocols and Ports tab (Wizard page 4)

 

Item Detail

Select the protocol this QoS policy applies to:

Choose to apply the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound TCP traffic, UDP traffic, or both.

From any source port

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic, regardless of the source port number of the traffic.

From this source port number or range

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) only to traffic with the source port number or range you specify. You can type a port number between 1 and 65535 or a port range, in the format of "Low:High," where Low and High represent the lower bounds and upper bounds of the port range, inclusively. Low and High each must be a number between 1 and 65535. No space is allowed between the colon (:) character and the numbers.

To any destination port

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) to outbound traffic, regardless of the destination port number of the traffic.

To this destination port number or range

Applies the DSCP value and throttle rate specified on the Policy Profile tab (Wizard page 1) only to traffic with the destination port number or range you specify. You can type a port number between 1 and 65535 or a port range, in the format of "Low:High," where Low and High represent the lower bounds and upper bounds of the port range, inclusively. Low and High each must be a number between 1 and 65535. No space is allowed between the colon (:) character and the numbers.
