Detailed Description

The Disable-NetAdapterChecksumOffload cmdlet disables the selected checksum offloads on the network adapter. When specified, IPv4, TCPv4, and TCPv6 checksums can be disabled. If none of these parameters are passed into this cmdlet, then by default all of the checksums for this adapter are disabled. Physical network adapters have various checksum offloads in which the checksum calculations occur in the network adapter and not in the main processor. This reduces processor utilization and can increase network throughput. This cmdlet disables the various checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4, and UDPv6. Note: Disabling checksum offload will also disable other stateless offloading including Receive Side Scaling (RSS), Receive Segment Coalescing (RSC) and Large Send Offload (LSO).

Parameters

-AsJob <SwitchParameter>

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 <SwitchParameter>

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.

-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.
