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.



Required? true

Position? named

Default value

Accept pipeline input? true (ByPropertyName)

Accept wildcard characters? true



-IpIPv4 [<SwitchParameter>]

Indicates that this cmdlet enables checksum offload for IPv4 traffic.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Name <String[]>

Specifies an array of network adapter names.



Required? true

Position? 1

Default value

Accept pipeline input? true (ByPropertyName)

Accept wildcard characters? true



-NoRestart [<SwitchParameter>]

Indicates that the cmdlet does not restart the network adapter after completing the operation. Many advanced properties require restarting the

network adapter before the new settings take effect.



Required? false

Position? named

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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-TcpIPv4 [<SwitchParameter>]

Indicates that the cmdlet enables checksum offload for TCP IPv4 traffic.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-TcpIPv6 [<SwitchParameter>]

Indicates that the cmdlet enables checksum offload for TCP IPv6 traffic.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-UdpIPv4 [<SwitchParameter>]

Indicates that the cmdlet enables checksum offload for UDP IPv4 traffic.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-UdpIPv6 [<SwitchParameter>]

Indicates that the cmdlet enables checksum offload for UDP IPv6 traffic.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



-WhatIf [<SwitchParameter>]

Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs. The cmdlet is not run.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see
