Should i disable ipv4 checksum offload

Additionally, follow these steps:. To apply the Receive-Side Scaling settings, a reboot is required. To check if it is enabled, you can run the same command as for Receive-Side Scaling in an elevated command prompt:.

To disable it, run this command in an elevated command prompt:. Afterwards, reboot the machine to apply the changes. Some cluster applications require TCP Offload Engine to be enabled on each cluster node or replica for proper functionality.

As such, it is recommended not to edit any TCP Offload Engine settings for servers that are nodes or replicas in a clustered environment without first consulting the cluster application documentation. If the cluster documentation clearly confirms TCP Offload Engine settings can be changed without any negative effects, then proceed with the changes after creating a plan to roll back the changes if needed. If the NIC teaming documentation clearly confirms TCP Offload Engine settings can be changed without any negative effects, then proceed with the changes after creating a plan to roll back the changes if needed.

Generally, packet processing is more efficient with Interrupt Moderation enabled. High performance or low latency applications may need to evaluate the impact of disabling or reducing Interrupt Moderation.

Jumbo frames is a NIC and network feature that allows an application to send frames that are much larger than the default bytes. Typically the limit on jumbo frames is about bytes but may be smaller. This new offload works with Jumbo Frame settings to ensure encapsulated traffic doesn't require segmentation between the host and the adjacent switch. Receive Segment Coalescing, also known as Large Receive Offload, is a NIC feature that takes packets that are part of the same stream that arrives between network interrupts and coalesces them into a single packet before delivering them to the operating system.
