DESCRIPTION


The Disable-NetAdapterChecksumOffload cmdlet disables the selected checksum offloads on the network adapter. When specified, IPv4, TCPv4, and TCPv6 checksums can be
disabled. If none of these parameters are passed into this cmdlet, then by default all of the checksums for this adapter are disabled. 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 disables the various checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4, and UDPv6. Note: Disabling checksum offload will also disable
other stateless offloading including Receive Side Scaling (RSS), Receive Segment Coalescing (RSC) and Large Send Offload (LSO).
