Detailed Description

The Disable-NetAdapterQos cmdlet disables quality of service (QoS) on a network adapter. The QoS features, which include bandwidth allocation and priority based flow control, are specified in the IEEE data center bridging (DCB) standard. When QoS is disabled, the computer will not send to the network adapter any configuration for the QoS features. This cmdlet does not stop the network adapter from setting up configurations and utilizing the hardware QoS capabilities.

A network adapter that supports DCB is typically known as a converged network adapter. It supports both storage and networking functionalities. In some use cases the DCB must be enabled to support the storage functionalities. If DCB on a network adapter is disabled from the point of view of a computer, then it may still be functioning on the network adapter.

-CimSession<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.

-IncludeHidden

Indicates that the cmdlet includes both visible and hidden network adapters in the operation. By default only visible network adapters are included. If a wildcard character is used in identifying a network adapter and this parameter has been specified, then the wildcard string is matched against both hidden and visible network adapters.

-InterfaceDescription<String[]>

Specifies an array of network adapter interface descriptions. For a physical network adapter this is typically the name of the vendor of the network adapter followed by a part number and description, such as Contoso 12345 Gigabit Network Device.

-NoRestart

Indicates that the cmdlet does not restart the network adapter after completing the operation. Many advanced properties require restarting the network adapter before the new settings take effect.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

<CommonParameters>

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapterQosSettingData[]

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
    The input object is a list of network adapter objects, such as output from the Get-NetAdapter cmdlet.


Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.Management.Infrastructure.CimInstance# ROOT/StandardCimv2/MSFT_NetAdapterQosSettingData

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
    The output object contains QoS capabilities and configurations on a network adapter. The output object is returned only when PassThru parameter is specified.


Examples

Example 1: Disable QoS on all network adapters

This command disables QoS on all network adapters and restarts the network adapters.


PS C:\> Disable-NetAdapterQos –Name "*"

Example 2: Disable QoS on a specified network adapter

This command disables QoS on a network adapter named Ethernet 2 and restarts the network adapter.


 

PS C:\> Disable-NetAdapterQos –Name "Ethernet 2"

Example 3: Get all network adapters that support QoS and disable them

The first command gets all network adapters that support QoS and stores the result in the variable named $NetAdapterQoS1.

The second command disables all network adapters that are stored in the $NetAdapterQoS1 and restarts them.


 

PS C:\> $NetAdapterQoS1 = Get-NetAdapterQos –Name "*"
PS C:\> Disable-NetAdapterQos –InputObject $NetAdapterQoS1
