Detailed Description

The Set-NetAdapterVmq cmdlet sets the virtual machine queue (VMQ) properties of the network adapter. VMQ is a scaling networking technology for Hyper-V switch that improves network throughput by distributing processing of network traffic for multiple virtual machines (VMs) among multiple processors. A thorough familiarity with VMQ and dynamic VMQ is highly recommended before changing any default values with this cmdlet.

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.

-BaseProcessorGroup<UInt16>

Specifies the processor group to be used by VMQ. Support for systems that have more than 64 logical processors is based on the concept of a processor group, which is a static set of up to 64 logical processors. Processor groups are numbered starting with 0. Computers with fewer than 64 logical processors always have a single group, Group 0.

-BaseProcessorNumber<Byte>

Specifies the starting processor to be used within the processor group for VMQ. Support for systems that have more than 64 logical processors is based on the concept of a processor group, which is a static set of up to 64 logical processors. Processor groups are numbered starting with 0. Computers with fewer than 64 logical processors always have a single group, Group 0. A logical processor is identified by a group number, using the BaseProcessorGroup parameter, and a group-relative processor number, using this parameter.

-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_NetAdapterVmqSettingData[]

    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.


Outputs

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

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

    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.


Examples

EXAMPLE 1

This example enables VMQ on the network adapter named MyAdapter. Note: The Enable-NetAdapterVmq cmdlet is the preferred cmdlet to perform this operation.


PS C:\> Set-NetAdapterVmq –Name MyAdapter -Enabled $True
