9 Installing and Configuring Data Encryption Offloads The 3CR990B NIC performs data encryption processing offloads in Windows 2003, Windows XP, and Windows 2000. The 3CR990B NIC does not encrypt the data itself: the operating system performs that function. Encryption processing is handled entirely by the NIC. The NIC enables true end-to-end network security at the data capacity of the connected network cable, without sacrificing performance.
9 Installing and Configuring Data Encryption Offloads Configuring IPSec in Windows 2003, Windows XP, and Windows 2000 The 3CR990B NIC accelerates IP security (IPSec) data encryption from supported operating systems that provide this offload capability. This feature is currently available in the Windows 2003, Windows XP, and Windows 2000 operating systems.

10 Installing 3Com Advanced Server Features for Windows This chapter explains the following tasks for a computer running Windows 2003, Windows XP, Windows 2000, or Windows NT 4.0 with the 3Com 10/100 Secure (3CR990B) NIC installed. NOTE: Windows 98 does not support the advanced server features.
10 Installing 3Com Advanced Server Features for Windows Load Balancing Load balancing maximizes bandwidth at the server through the use of multiple parallel resilient server links (RSLs) that share the network load as shown in the next figure. An RSL consists of two or more NICs that form a virtual NIC. Each virtual NIC has multiple physical NICs bound to it, forming a group. Each NIC in a group uses the same protocols and frame types. One NIC is designated the primary NIC and the others secondary NICs.
Server Features Using Other NICs VLANs A virtual LAN (VLAN) is a group of location-independent and topology-independent devices that communicate as if they were on the same physical LAN. Network devices on different LAN segments and of different media types can be members of the same VLAN. Membership in a VLAN is determined by a VLAN tag that is transmitted with the Ethernet frame for use by a switch.
10 Installing 3Com Advanced Server Features for Windows Installing 3Com Advanced Server Software Follow these steps to install 3Com Advanced Server (DynamicAccess) software: 1 Make sure that the NIC and the network driver are properly installed in your computer. 2 Start Windows. 3 Insert the 3Com Installation CD in the CD-ROM drive. The Welcome screen appears. 4 Click NIC Software. 5 Click DynamicAccess technologies. 6 Click Install DynamicAccess software.
Planning the Configuration Configuring Groups and VLANs 3Com Advanced Server technology features allow you to configure load balancing groups and virtual LANs (VLANs). The following 3Com Advanced Server technology features are available for NIC groups in Windows: • Load balancing • RSL failover • Multiple VLANs The examples in this section illustrate typical actions you might take in the course of maintaining a 3Com Advanced Server configuration in Windows.
10 Installing 3Com Advanced Server Features for Windows • The following guidelines apply to groups under Windows 2003, Windows XP, and Windows 2000: 802.1p Support Property—The value of the Windows 802.1p support property must be the same for all NICs in a group. For example, if this property is enabled for the primary NIC, it must also be enabled for all other NICs in the group.
Creating a Group Windows 2003, Windows XP, and Windows 2000 Access 3Com Advanced Server server features through the Windows Network and Dial-up Connections window as follows: 1 Log in to Windows with administrator privileges. 2 Launch the Windows Network and Dial-up Connections window. 3 Select a Local Area Connection icon. 4 Click the right mouse button and select Properties. The Local Area Connections Properties window appears. 5 Click the General tab.
10 Installing 3Com Advanced Server Features for Windows To disable all load balancing—Clear the Receive Load Balance Enabled and the Transmit Load Balance Enabled check boxes. 5 Click OK. The name of the new NIC group appears in the Load Balancing/RSL Groups list box. Adding NICs to a Group 1 Click the Load Balance/RSL tab. 2 In the Load Balance/RSL window: • Select a group from the Load Balancing/RSL Groups list. • Select a NIC from the Network Interface Cards list. 3 Click Add NIC.
Changing an IP Address Changing an IP Address If another device is using a bidirectional load balancing group's dedicated IP address, you must change either the other device’s IP address or that of the load balancing group. Use the appropriate procedure below: Changing the Other Device’s IP Address After you change the other device's address, restart receive load balancing as follows: 1 In the Load Balancing/RSL window, select the group that had the duplicate address. 2 Click Properties.
10 Installing 3Com Advanced Server Features for Windows Saving the Configuration To save and exit, click OK. To exit without saving the configuration, click Cancel. Disabling Load Balancing for a Group Follow these steps to disable load balancing for a group: 1 Click the Load Balance/RSL tab. 2 In the Load Balance/RSL window: • Select a group from the Load Balancing/RSL Groups list. • Click Properties.
Displaying NIC Properties Displaying NIC Properties Follow these steps to display NIC properties: 1 Click the Load Balance/RSL tab. 2 In the Load Balance/RSL window, select a NIC. 3 Click Properties. The NIC Properties window appears, showing the properties of the selected NIC. Displaying Group Properties Follow these steps to display group properties: 1 Click the Load Balance/RSL tab. 2 In the Load Balance/RSL window, select a group in the Load Balancing/RSL Groups list box. 3 Click Properties.
10 Installing 3Com Advanced Server Features for Windows Changing Windows 2003, Windows XP, and Windows 2000 Property Settings If you receive warnings about inconsistent property settings (for example, the 802.1p Support property) while creating a group, use the following procedure to change a NIC property: 1 Right-click the My Computer icon and select Properties from the menu. 2 Click the Hardware tab, then click Device Manager. 3 Double-click Network Adapters.
Enabling Offloads • IP and TCP Checksum Offload—reduced CPU utilization by allowing the NIC to perform the checksum calculation of TCP/IP and UDP/IP packets. • 802.1p Packet Priority Offload—reduces CPU utilization by allowing the NIC to perform the insertion of the 802.1Q tag header into the packet. Enabling Offloads Windows 2003 and Windows 2000 provide the capability to individually enable or disable each of the four offload features. (The default setting for these features is enabled.
10 Installing 3Com Advanced Server Features for Windows Configuring Offloads for a Group of Different NICs Your computer may contain a combination of installed NICs (including one or more 3CR990Bs with varying offload capabilities). If you have a mix of dissimilar NICs configured in a group, then 3Com DynamicAccess Advanced Server software supports only those offload functions that are supported by all the NICs in the group.
11 Configuring the NIC This chapter describes how to configure the 3Com 10/100 Secure (3CR990B) NIC. NOTE: Before you change the NIC configuration settings, contact your system administrator. Default NIC Settings The table below lists the configuration settings for the NIC. The default setting is shown in bold in the Settings column. Option Description Settings NetBoot ROM Provides the ability to boot a computer over the network.
11 Configuring the NIC Option Description Settings Media Type Determines the type of media your network is using. • Auto Select allows the NIC to automatically select the Media Type for you. • If you set the NIC Duplex setting to Auto Select, the Media Type is automatically set to Auto Select. • If you set the NIC Duplex setting manually, you must set the Media Type setting manually.
