The first command gets the state of checksum offload properties from the network adapter named MyAdapter and stores the result in the variable named $NetworkAdapterC01. PS C:\> $NetworkAdapterC01.ChecksumOffloadHardwareCapabilities Example 2: Get the checksum offload properties of the specified network adapter and display them PS C:\> $NetworkAdapterC01 = Get-NetAdapterChecksumOffload -Name "MyAdapter" If no files are specified, the cksum command reads standard input. The cksum command reads the files specified by the File parameter and calculates a 32-bit checksum Cyclic Redundancy Check (CRC) and the byte count for each file. This command gets the state of checksum offload properties of the network adapter named MyAdapter. Displays the checksum and byte count of a file. Examples Example 1: Get the checksum offload properties of the specified network adapter PS C:\> Get-NetAdapterChecksumOffload -Name "MyAdapter" This cmdlet gets the various checksum offload settings, including IPv4, TCPv4, TCPv6, UDPv4, and UDPv6.
Before the TCP/IP transport passes a NETPACKET structure to the client driver, it specifies the checksum information associated with the NETPACKET in a NETPACKETCHECKSUM packet extension. This reduces processor utilization and can increase network throughput. NetAdapterCx supports offloading TCP/IP checksum tasks at run time. Physical network adapters have various checksum offloads in which the checksum calculations occur in the network adapter and not in the main processor. The Get-NetAdapterChecksumOffload cmdlet gets the various checksum offload settings. Move the file that you want to check the checksum value for to the same directory as the one you extracted the File Checksum Integrity Verifier utility to and then run the following command to run the check. In this article Syntax Get-Net Adapter Checksum Offload Open Command Prompt and use the cd command to move to the folder you extracted the tool to. Gets the various checksum offload settings from network adapters that support these checksum offloads.
