Modifying Advanced Properties  > TCP/UDP Checksum Offload (IPv4)

TCP/UDP Checksum Offload (IPv4)

The TCP/UDP Checksum Offload (IPv4) function enables the adapter to compute the checksum of transmitting IPv4 packets and verify the checksum of receiving IPv4 packets, taking load off from the CPU.

To modify the TCP/UDP Checksum Offload (IPv4) setting, do the following:

1. Access the Device Manager on your operating system.

See Accessing Advanced Properties.

2. Select TCP/UDP Checksum Offload (IPv4) in the Property box.

The TCP/UDP Checksum Offload (IPv4) page is displayed as shown in Figure 60.

Rx & Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv4) function for both receiving and transmitting IPv4 packets. This is the default setting.

Disabled — Disables the TCP/UDP Checksum Offload (IPv4) function for both receiving and transmitting.

Rx Enabled — Enables the TCP/UDP Checksum Offload (IPv4) function only for receiving IPv4 packets.

Tx Enabled — Enables the TCP/UDP Checksum Offload (IPv4) function only for transmitting IPv4 packets.
