Detailed Description

The Set-NetAdapterChecksumOffload cmdlet sets the state of the checksum offload properties. The network adapter computes the checksums, therefore reducing processor utilization because the processor is not performing this computation. This cmdlet sets the various checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4, and UDPv6. This cmdlet enables a few types of checksums while disabling others. If only setting the enabled state, run the Enable-NetAdapterChecksumOffload or Disable-NetAdapterChecksumOffload 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.

-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

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.

-IpIPv4Enabled<Direction>

Specifies the direction of the IP traffic for IPv4. The acceptable values for this parameter are: Disabled, RxTxEnabled, RxEnabled, or TxEnabled. If RxEnabled or TxEnabled is selected, then the opposite direction (transmit or receive, respectively) is disabled. Such as if the state is RxEnabled, then checksum calculations for receive traffic is enabled and for transmit traffic is Disabled.

-TcpIPv4Enabled<Direction>

Specifies the direction of the TCP traffic for IPv4. The acceptable values for this parameter are: Disabled, RxTxEnabled, RxEnabled, or TxEnabled. If RxEnabled or TxEnabled is selected, then the opposite direction (transmit or receive, respectively) is disabled. Such as if the state is RxEnabled, then checksum calculations for receive traffic is enabled and for transmit traffic is Disabled.

Specifies the direction of the TCP traffic for IPv6. The acceptable values for this parameter are: Disabled, RxTxEnabled, RxEnabled, or TxEnabled. If RxEnabled or TxEnabled is selected, then the opposite direction (transmit or receive, respectively) is disabled. Such as if the state is RxEnabled, then checksum calculations for receive traffic is enabled and for transmit traffic is Disabled.

-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.

If RxEnabled or TxEnabled is selected, then the opposite direction (transmit or receive, respectively) is disabled. Such as if the state is RxEnabled, then checksum calculations for receive traffic is enabled and for transmit traffic is Disabled.

<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_NetAdapter ChecksumOffloadSettingData[]

    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_NetAdapter ChecksumOffloadSettingData[]

    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 the IPv4 checksum offload in both receive and transmit directions on all visible network adapters.


PS C:\> Set-NetAdapterChecksumOffload –Name * -IpIPv4Enabled RxTxEnabled

EXAMPLE 2

This example enables the IPv4 checksum, the UDPv4 and IPv4 checksum, and the TCPv4 and IPv4 checksum in both receive and transmit directions on the network adapter named MyAdapter.


PS C:\> Set-NetAdapterChecksumOffload –Name MyAdapter -IpIPv4Enabled RxTxEnabled -TcpIpv4Enabled RxTxEnabled -UdpIpv4Enabled RxTxEnabled
