Updating the
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 Advanced tab:
For Windows Server 2003 Operating systems, see “Selecting the
Advanced Tab in Windows Server 2003 or Windows XP” on
page 58.
For Windows 7 Operating systems, see “Selecting the Advanced
Tab in Windows 7” on page 61.
For Windows Vista Operating systems, see “Selecting the
Advanced Tab in Windows Vista” on page 63.
The Advanced tab is shown in Figure 30 on page 60.
2. From the Property list on the Advanced tab, select one of the following:
IPv4 Large Send Offload
IPv6 Large Send Offload
3. 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.
4. Click OK.
5. 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.
6. Verify that the port LED operates correctly. See one of the following
