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 to not accept configurations from a remote device, the computer sends 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 enables 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, you can use 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 through 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.
Examples
Example 1: Enable QoS on the specified network adapter
PS C:\> Enable-NetAdapterQos -Name "DCBNIC1"
This command enables QoS on a network adapter named DCBNIC1 and restarts the network adapter.
Example 2: Enable QoS on all network adapters that support QoS
This command 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 command 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
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.

-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
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.

Outputs
CimInstance
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.
