Detailed Description
The Enable-NetAdapterSriov cmdlet enables Single-Root I/O Virtualization (SR-IOV) on the network adapter. SR-IOV enables network traffic to by-pass the software switch layer of the Hyper-V virtualization stack. As a result, the I/O overhead in the software emulation layer is diminished and can achieve network performance that is nearly the same performance as in non-virtualized environments. SR-IOV can only be used if enabled on the network adapter.

-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[]>
Specifies the network adapter interface description. 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
.

-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 (https://go.microsoft.com/fwlink/p/?LinkID=113216).
Inputs
The input type is the type of the objects that you can pipe to the cmdlet.
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
The output type is the type of the objects that the cmdlet emits.
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.
Examples
EXAMPLE 1
This example enables SR-IOV for the network adapter named Ethernet 1 and restarts the network adapter.
PS C:\> Enable-NetAdapterSriov -Name "Ethernet 1"
EXAMPLE 2
This example enables SR-IOV for the network adapter with the description Contoso 12345 Gigabit Network Device and restarts the network adapter.
PS C:\> Enable-NetAdapterSriov -InterfaceDescription "Contoso 12345 Gigabit Network Device"
EXAMPLE 3
This example inputs the network adapter object into this cmdlet.
PS C:\> $netAdapter = Get-NetAdapter -Name "Ethernet 2"
PS C:\> Enable-NetAdapterSriov –InputObject $netAdapter
This is a version of the cmdlet that selects the network adapter and pipes the network adapter object into this cmdlet.
PS C:\> Get-NetAdapter -Name "Ethernet 2" | Enable-NetAdapterSriov
