Description
The Enable-NetAdapterChecksumOffload cmdlet enables checksum offloads on the network adapter. When specified IPv4, TCPv4, or TCPv6 can be enabled in the transmit, 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).
Examples
EXAMPLE 1
PS C:\>Enable-NetAdapterChecksumOffload -Name * -TcpIPv4 -UdpIPv4 -IpIPv4
This example enables all IPv4 checksum offloads on all visible network adapters and restarts the network adapters.
EXAMPLE 2
PS C:\>Enable-NetAdapterChecksumOffload -Name *
This example enables all checksum offloads on all visible network adapters and restarts the network adapters.
Parameters
-AsJob
ps_cimcommon_asjob
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
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[] |
Aliases: | Session |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
Type: | SwitchParameter |
Aliases: | cf |
Position: | Named |
Default value: | False |
Required: | 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 |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-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 |
Required: | True |
Accept pipeline input: | True |
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, InstanceID |
Position: | Named |
Default value: | None |
Required: | True |
Accept pipeline input: | True |
Accept wildcard characters: | False |
-IpIPv4
Enables checksum offload for IPv4 traffic.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Name
Specifies the name of the network adapter.
Type: | String[] |
Aliases: | ifAlias, InterfaceAlias |
Position: | 0 |
Default value: | None |
Required: | True |
Accept pipeline input: | True |
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 |
Required: | False |
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 |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-TcpIPv4
Enables checksum offload for TCP IPv4 traffic.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-TcpIPv6
Enables checksum offload for TCP IPv6 traffic.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
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 |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-UdpIPv4
Enables checksum offload for UDP IPv4 traffic.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-UdpIPv6
Enables checksum offload for UDP IPv6 traffic.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Type: | SwitchParameter |
Aliases: | wi |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
