Large Send

Offload Property

Normally, the protocol stack performs TCP segmentation. When you
enable the Large Send Offload property, the network adapter does the
TCP segmentation. There are several Large Send Offload properties to
choose from, depending on the TCP/IP version you are using on your PC.
You can select IPV4, IPV4 version 2, or IPv6 version 2. By default, the
Large Send Offload Property is disabled.

To change the Large Send Offload property, do the following:

1. Access the Device Manger for your operating system.

To access the Windows XP Device Manager, see “Selecting the
Device Manager Window” on page 47
.

To access the Windows Vista Device Manager, see “Selecting the
Device Manager” on page 39.

To access the Windows 7 Device Manager, see “Selecting the
Device Manager Window” on page 54
.

2. Click the Advanced tab.

The Advanced tab is shown in Figure 31 on page 64.

3. From the Property list on the Advanced tab, select one of the following:

Large Send Offload (IPv4)

Large Send Offload v2 (IPv4)

Large Send Offload v2 (IPv6)

4. From the Value list on the Advanced tab, select one of the following:

Enable - Enables the Large Send Offload property.

Disable - Disables the Large Send Offload property. This is the
default.

5. Click OK.

6. If prompted to restart your computer, click Yes.

Although it is not necessary to reboot the system for new adapter
properties to take effect, rebooting is recommended to reinitialize all
registers.

7. Verify that the port LED operates as described in “Physical

Description” on page 20.
