Parameter Set: ByInstanceID
Get-NetAdapterRsc -InterfaceDescription <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-IncludeHidden] [-IPv4FailureReason <FailureReason[]> ] [-IPv4OperationalState <Boolean[]> ] [-IPv6FailureReason <FailureReason[]> ] [-IPv6OperationalState <Boolean[]> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The Get-NetAdapterRsc cmdlet gets network adapters that support receive segment coalescing (RSC). RSC takes multiple packets received within the same interrupt period and combines the packets into a single large package to be processed by the network stack. This reduces the processing overhead for incoming packets and reduces the number of processor cycles that are used, leading to better scalability.

-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.

-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<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.

-IPv4FailureReason<FailureReason[]>

Specifies the reason that RSC may not be working on IPv4 traffic.

The acceptable values for this parameter are:

-- NoFailure
-- NicPropertyDisabled
-- WFPCompatibility
-- NDISCompatibility
-- ForwardingEnabled
-- NetOffloadGlobalDisabled

-IPv6FailureReason<FailureReason[]>

Returns the reason that of RSC may not be working on IPv6 traffic.

The acceptable values for this parameter are:

-- NoFailure
-- NicPropertyDisabled
-- WFPCompatibility
-- NDISCompatibility
-- ForwardingEnabled
-- NetOffloadGlobalDisabled

If RSC is desired, then the following actions can be taken:

-- NicPropertyDisabled: Run the Enable-NetAdapterRsc cmdlet to enable RSC on the specified network adapter.
-- WFPCompatibility: Disable the WFP filters.
-- NDISCompatibility: Upgrade to an NDIS 6.30 driver.
-- ForwardingEnabled: Disable forwarding.
-- NetOffloadGlobalDisabled: Run the Set-NetOffloadGlobalSetting cmdlet with the ReceiveSegmentCoalescing parameter set to Enabled.

-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: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • None

Outputs

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

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

    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: Get the RSC properties for the specified network adapter

This command gets the RSC properties of the network adapter named MyAdapter.


PS C:\> Get-NetAdapterRsc –Name "MyAdapter"

Example 2: Get all RSC capable network adapters

This command gets all of the RSC capable network adapters.


PS C:\> Get-NetAdapterRsc –Name "*"

Example 3: Get all RSC capable network adapters that have RSC enabled

This command gets all of the RSC capable network adapters that have RSC enabled.


PS C:\> Get-NetAdapterRsc –Name "*" | Where-Object -FilterScript { $_.Enabled }
