Detailed Description

The Enable-NetAdapterQos cmdlet enables quality of service (QoS) on a network adapter. The QoS features, which include traffic class bandwidth allocation and priority based flow control, are specified in the IEEE data center bridging (DCB) standard. When QoS is enabled and the computer is configured not to accept configurations from a remote device, the computer will send to the network adapter the user-generated configurations for the QoS features. For more information about the configuring the computer not to accept configurations from a remote device, see the Set-NetQosDcbxSetting cmdlet. Otherwise, the network adapter will enable the QoS features based on either the factory default configurations or what it receives from the remote device.

To configure traffic class bandwidth allocation and priority based flow control on the computer, users can run the New-NetQosTrafficClass and the Enable-NetQosFlowControl cmdlets.

Some switches expect end stations, such as computers running Windows Server® 2012 or later, to accept configurations from the switches. If the switches detect a mismatched configuration via the data center bridging exchange (DCBX) protocol, then the switches disable the DCB functionalities. To overcome this limitation, users can disable DCBX on either the switches or the network adapters and manually configure the features on either end.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-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

Specifies both visible and hidden network adapters should be included. 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[]>

-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: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. 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 the PassThru parameter is specified.


Examples

EXAMPLE 1

This example enables QoS on a network adapter named DCBNIC1 and restarts the network adapter.


PS C:\> Enable-NetAdapterQos –Name "DCBNIC1"

EXAMPLE 2

 

This example gets all network adapters that support QoS, enables QoS on all of them, and restarts the network adapter.


PS C:\> $netadapter1 = Get-NetAdapterQos –Name *
PS C:\> Enable-NetAdapterQos –InputObject $netadapter1

 

This is a version of the cmdlet that gets all network adapters that support QoS and enables QoS on all of them via the pipeline, then restarts the network adapter.


PS C:\> Get-NetAdapterQos –Name * | Enable-NetAdapterQos
