Parameters

-AppPathNameMatchCondition: Specifies the name by which an application is run in Windows Server® 2012, such as application.exe or %ProgramFiles%\application.exe.
-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-CimSession: Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm: Prompts you for confirmation before running the cmdlet.
-DSCPAction: Specifies the differentiated services code point (DSCP) value. A valid DSCP value is in the range between 0 and 63. In addition, users can enter -1 to remove the DSCP setting from the policy.
-IPDstPortEndMatchCondition: Specifies the last port in a range of destination ports to be used to match the network traffic. This parameter must be used in conjunction with the *IPDstPortStartMatchCondition* parameter. The value of this parameter also must be larger than the value of the *IPDstPortStartMatchCondition* parameter.
-IPDstPortMatchCondition: Specifies the exact destination port to be used to match the network traffic. The filter of a QoS policy can be based on either a single port or a range of ports. To specify a single destination port, use this parameter. To specify a range of destination ports, use both the *IPDstPortStartMatchCondition* and the *IPDstPortEndMatchCondition* parameters.
-IPDstPortStartMatchCondition: Specifies the first port in a range of destination ports to be used to match the network traffic. This parameter must be used in conjunction with the *IPDstPortEndMatchCondition* parameter. The value of this parameter also must be smaller than the value of the *IPDstPortEndMatchCondition* parameter.
-IPDstPrefixMatchCondition: Specifies the destination IP address, optionally with a network prefix, such as 1.2.3.4, 3ffe:ffff::1, 192.168.1.0/24, or fe80::1234/48.
-IPPortMatchCondition: Specifies the port to be used to match the network traffic, it can be either source port or destination port. If either the source port or the destination port in a packet matches the value of this parameter, then the QoS policy will apply to the packet. Usually this is a well-known port that a client uses to communicate with a server. With this parameter specified, the same QoS policy can be configured on both the clients and the servers and apply to the traffic in both directions. For example, specifying this parameter value to 80 matches HTTP traffic sent by both HTTP clients and HTTP servers.

Prerequisites

Windows with the NetQos module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.

Examples

Example 1: Update a QoS policy to apply to outgoing traffic from a domain-joined adapter

Set-NetQosPolicy -Name "SMB Policy" -NetworkProfile Domain

This command updates the QoS policy named SMB Policy so that it only applies to traffic that is outgoing from a domain-joined network adapter. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
