DESCRIPTION


The Enable-NetAdapterChecksumOffload cmdlet enables checksum offloads on the network adapter. When specified IPv4, TCPv4, or TCPv6 can be enabled in the transmit, rec
eive, or both directions. By default all checksums are enabled in both directions. Physical network adapters have various checksum offloads in which the checksum calc
ulations occur in the network adapter and not in the main processor. This reduces processor utilization and can increase network throughput. This cmdlet enables the v
arious checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4, and UDPv6. Checksum offloading is also required for other stateless offloads to work including
receive side scaling (RSS), receive segment coalescing (RSC), and large send offload (LSO).
