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. 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>]
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 the cmdlet disables IPv4 checksum offloading.
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 disables TCP IPv4 checksum offloading.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-TcpIPv6 [<SwitchParameter>]
Indicates that the cmdlet disables TCP IPv6 checksum offloading.
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 disables UDP IPv4 checksum offloading.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-UdpIPv6 [<SwitchParameter>]
Indicates that the cmdlet disables UDP IPv6 checksum offloading.
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
