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.

Examples

EXAMPLE 1

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

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

EXAMPLE 2

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

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.

Required Parameters

-InputObject

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type:CimInstance[]
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False
-InterfaceDescription

Specifies the network adapter interface description. 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.

Type:String[]
Aliases:ifDesc
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:True
-Name

Specifies the name of the network adapter.

Type:String[]
Aliases:ifAlias, InterfaceAlias
Position:1
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:True

Optional Parameters

-AsJob

ps_cimcommon_asjob

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-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-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-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.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-IpIPv4Enabled

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.

Type:Direction
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-NoRestart

Specifies that the network adapter is not restarted as part of running this cmdlet. Note: Many advanced properties require restarting the network adapter before the new settings take effect.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-TcpIPv4Enabled

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.

Type:Direction
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-TcpIPv6Enabled

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.

Type:Direction
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ThrottleLimit

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.

Type:Int32
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-UdpIPv4Enabled

Specifies the direction of the UDP 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.

Type:Direction
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-UdpIPv6Enabled

Specifies the direction of the UDP 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.

Type:Direction
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-WhatIf

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

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapter ChecksumOffloadSettingData[]
