UDP Segmentation Offload (IPv4 and IPv6)

This setting allows the adapter to segment UDP packets with payloads up to 64K into valid Ethernet frames. Because the adapter hardware is able to complete data segmentation much faster than operating system software, this feature may improve transmission performance. In addition, the adapter may use fewer CPU resources.

With Offloading off, the operating system segments UDP packets into valid Ethernet frames.

With Offloading on, the adapter segments UDP packets for the operating system.

Note:

UDP Segmentation Offload requires:

  • Microsoft* Windows Server* 2019, Version 1903, or later

  • Linux* kernel 4.18, or later

To change this setting in Intel® PROSet:

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

Set-IntelNetAdapterSetting -Name "<adapter_name>" -DisplayName "UDP Segmentation
Offload (IPv4)" -DisplayValue "Enabled"

Possible values for this setting are:

  • Enabled

  • Disabled
