IPv4 Checksum Offload

This setting allows the adapter to compute the IPv4 checksum of incoming and outgoing packets. This feature enhances IPv4 receive and transmit performance and reduces CPU utilization.

With Offloading off, the operating system verifies the IPv4 checksum.

With Offloading on, the adapter completes the verification (on RX) and computation (on TX) for the operating system.

To change this setting in Intel® PROSet:

This setting is found on the Advanced tab of the device’s Device Manager property sheet or in the Adapter Settings panel in Intel® PROSet Adapter Configuration Utility (Intel® PROSet ACU).

To change this setting in Windows PowerShell*, use the Set-IntelNetAdapterSetting cmdlet. For example:

Set-IntelNetAdapterSetting -Name "<adapter_name>" -DisplayName "IPv4 Checksum Offload"
-DisplayValue "Tx Enabled"

Possible values for this setting are:

  • Disabled

  • RX Enabled

  • TX Enabled

  • RX & TX Enabled
