DESCRIPTION

The Set-NetAdapterSriov cmdlet sets the Single-Root I/O Virtualization (SR-IOV) properties of the network adapter. The properties include the

number of virtual functions, the number of virtual ports (VPorts), and the number of queue pairs for default and non-default VPorts. The enabled

state of SR-IOV can also be set with the cmdlet.



The network adapter for these actions can be specified with the adapter name, interface description, or piped as an input object.





PARAMETERS

-AsJob [<SwitchParameter>]

ps_cimcommon_asjob



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Enabled <Boolean>

Indicates whether SR-IOV is enabled on the network adapter. If set to $True, then SR-IOV is Enabled. If set to $False, then SR-IOV is Disabled.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-IncludeHidden [<SwitchParameter>]

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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-InputObject <CimInstance[]>

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.



Required? true

Position? named

Default value

Accept pipeline input? true (ByValue)

Accept wildcard characters? false



-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.



The network adapter can be selected using the Name parameter, this parameter, or piped in using the InputObject parameter.



Required? true

Position? named

Default value

Accept pipeline input? true (ByPropertyName)

Accept wildcard characters? true



-Name <String[]>

Specifies an array of network adapter names.



The network adapter can be selected using this parameter, the InterfaceDescription parameter, or piped in using the InputObject parameter.



Required? true

Position? 1

Default value

Accept pipeline input? true (ByPropertyName)

Accept wildcard characters? true



-NoRestart [<SwitchParameter>]

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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-NumVFs <UInt32>

Specifies the number of virtual functions that the network adapter exposes for SR-IOV. This is the maximum number of virtual functions that

Windows Server 2012 and later allocates on this network adapter.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-PassThru [<SwitchParameter>]

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



-WhatIf [<SwitchParameter>]

Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs. The cmdlet is not run.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapterSriovSettingData[]



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

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapterSriovSettingData



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 will have the updated SR-IOV settings.





Example 1: Set the number of virtual functions on the specified network adapter



PS C:\\>Set-NetAdapterSriov -Name "Ethernet 2" -NumVFs 31



This command sets the number of virtual functions available to 31 on the network adapter named Ethernet 2.





Example 2: Set the number of virtual functions and VPorts on the specified network adapter



PS C:\\>Set-NetAdapterSriov -Name "Ethernet 2" -NumVFs 31 -VPorts 64 -NumQueuePairsForDefaultVPort 2 -NumQueuePairsForNonDefaultVPort 2



This command sets the number of virtual functions to 31 and the total number of VPorts to 64. This results in 31 virtual functions and 32 virtual

machine queues (VMQ), plus 1 used by the physical function. Since the number of queue pair is set to 2 for both default and non-default ports, the

total number of queue pairs used is 128.
