Get-NetAdapterSriovVf

Last Updated: 3/8/2017

SYNOPSIS

Displays the SR-IOV virtual function settings for a network adapter.

SYNTAX

ByName (Default)

Get-NetAdapterSriovVf [[-Name] <String[]>] [-SwitchID <UInt32[]>] [-FunctionID <UInt16[]>] [-IncludeHidden]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

ByInstanceID

Get-NetAdapterSriovVf -InterfaceDescription <String[]> [-SwitchID <UInt32[]>] [-FunctionID <UInt16[]>]
 [-IncludeHidden] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

DESCRIPTION

The Get-NetAdapterSriovVf cmdlet displays the Single-Root I/O Virtualization (SR-IOV) virtual function settings for a network adapter. By default a table of virtual function settings will be displayed that includes the virtual function identifier (ID), virtual function name, network adapter ID, and the current MAC address. Specifying a single virtual function displays that virtual function in more detail. Additional displayed fields include the permanent MAC address, requester ID, and virtual port (VPort) information.

The network adapter to use is specified by either the name of the network adapter, interface description of the network adapter, or the switch ID of the virtual switch bound to the SR-IOV network adapter.

EXAMPLES

Example 1: Get a list of virtual functions, virtual machines, and MAC addresses for the specified network adapter

PS C:\> Get-NetAdapterSriovVf -Name "Ethernet 1"

This command gets a list of the virtual functions with the virtual machine names and MAC addresses for the network adapter named Ethernet 1.

Example 2: Get a list of virtual functions, virtual machines, and MAC addresses for a network adapter bound to a virtual switch

PS C:\> Get-NetAdapterSriovVf -SwitchId 2

This command gets a list of the virtual functions with the virtual machine names and MAC addresses for the network adapter bound to virtual switch 2.

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.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-FunctionID

Specifies the virtual function ID number on the indicated network adapter to return more detailed information on the virtual function.

Type: UInt16[]
Parameter Sets: (All)
Aliases: VfID, Id

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: String[]
Parameter Sets: ByInstanceID
Aliases: ifDesc, InstanceID

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Name

Specifies an array of network adapter names.

Type: String[]
Parameter Sets: ByName
Aliases: ifAlias, InterfaceAlias

Required: False
Position: 0
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-SwitchID

Specifies the virtual switch ID that identifies the network adapter for one or more virtual functions as an array.

Type: UInt32[]
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ThrottleLimit

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.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

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

None

OUTPUTS

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

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.
