DESCRIPTION
The Enable-NetAdapterChecksumOffload cmdlet enables checksum offloads on the network adapter. When specified IPv4, TCPv4, or TCPv6 can be enabled
in transmission, receive, or both directions. By default all checksums are enabled in both directions. 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 enables the various checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4,
and UDPv6. Checksum offloading is also required for other stateless offloads to work including receive side scaling (RSS), receive segment
coalescing (RSC), and large send offload (LSO).
PARAMETERS
-AsJob [<SwitchParameter>]
ps_cimcommon_asjob
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-IncludeHidden [<SwitchParameter>]
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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-InputObject <CimInstance[]>
Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
Required? true
Position? named
Default value
Accept pipeline input? true (ByValue)
Accept wildcard characters? false
-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.

network adapter before the new settings take effect.
Required? false

Default value
Accept pipeline input? false
Accept wildcard characters? false
-PassThru [<SwitchParameter>]
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-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.
