Detailed Description
Overview
The package DisableTCP-IPv6ChecksumOffload.zip (ZIP file) contains the following:
- Technical Brief (DisableTCP-IPv6ChecksumOffloadTechBrief_Rev1.0.pdf)
- Windows* PowerShell* script (DisableChecksumOffload.ps1)
Ensure that you have both items before proceeding.
Purpose
In some situations where a client machine is connected via some specific Optical Network Terminals (ONTs), and data is appended after the packet checksum, the network adapter can drop receive packets when using TCP-IPv6 Checksum Offload for receive traffic.
Products affected
All 1 GbE and 10 GbE Intel® Ethernet controllers and network adapters.
Recommended action
Download the file "DisableTCP-IPv6ChecksumOffload.zip" and follow the instructions in the "DisableTCP-IPv6ChecksumOffloadTechBrief_Rev1.0.pdf".
