Chapter 5: Setting Advanced Properties

For Windows 2008 R2, Windows 7, and Windows Vista systems, access the Device Manger for your operating system:

ˆTo access the Device Manager window in Windows 2008 R2 or Windows 7, see “Selecting the Device Manager in Windows 2008 R2 and Windows 7” on page 44.

ˆTo access the Windows Vista Device Manager, see “Selecting the Device Manager in Windows Vista” on page 46.

2.From the Advanced tab under Property, select Interrupt Moderation. For an example of the Advanced tab, see Figure 21 on page 56.

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

ˆEnabled

ˆDisabled

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 as described in “LEDs” on page 18.

IPSec Offload Traditionally, IPSec has been used for remote connections, but this feature has moved into the Local Area Network (LAN) to secure local network traffic against eavesdropping.

Vista’s Next Generation TCP/IP stack provides APIs for accessing brackets to allow advanced granularity to filter both inbound and outbound traffic.This was not possible with Microsoft’s XP Operating system. In addition, Vista’s security management now closely ties the firewall and IPSec features together by using a snap-in called Windows Firewall with Advanced Security. The onboard encryption engine on an AT-29xx Series adapter off-loads this task to the network controller instead of the host CPU, thereby freeing the host CPU for other important tasks. The off- loading feature is unique in the industry and enables you to set tight security efficiently within your network at a minimal cost.

Microsoft’s Technet website, www.technet.microsoft.com, offers several technical publications and online seminars that describe Vista’s advanced IPSec and Firewall features as well as their implementation. These topics are beyond the scope of this chapter. Instead, Allied Telesis recommends that you consult Technet for additional information.

By default, the IPSec Offload property is set to Disabled.
