1 INTRODUCTION Overview This chapter describes the following 3Com® EtherLink® 10/100 Mbps PCI network interface card (NIC) models from the 3CR990 NIC family.
CHAPTER 1: INTRODUCTION Onboard 3XP Processor The 3CR990 NIC represents a new generation of secure, intelligent client NICs with an onboard RISC processor (3XP processor). The 3XP processor is designed to optimize system and network performance. The NIC off-loads key networking and security tasks from the host PC CPU (central processing unit) to the 3XP processor, even when running bandwidth-intensive applications such as voice, video, imaging, and Internet and intranet applications.
3CR990 NIC Features 15 High Encryption Pack for Windows 2000 The Windows 2000 High Encryption Pack allows you to enhance your system with the highest available encryption level (168-bit). You can download the High Encryption Pack from the following Microsoft World Wide Web site: http://www.microsoft.com/WINDOWS2000/downloads /recommended/encryption/default.asp The Windows 2000 High Encryption Pack is eligible for export from the U.S. to all customers worldwide, except to U.S. embargoed destinations.
CHAPTER 1: INTRODUCTION Figure 1 The 3CR990 NIC Supports Up to 168-bit (3DES) Encryption Encryption chip Remote Wake-Up (RWU) connector TX D ATA ACT 10 L 100 N K 3XP Processor The 3CR990 NIC provides these features for supported IP and IPX environments: ■ Advanced Server Features (for 3CR990 server NICs only)—Improved network performance, management, and control: ■ Load Balancing ■ Self-Healing Drivers ■ Failover ■ VLANs ■ Traffic Prioritization ■ Remote Wake-Up—Lets you power-on a computer remotel
3CR990 NIC Features ■ ■ ■ 17 across the network to a DMI 2.0-compliant management application. Remote System Alerts (heartbeat packets)—Can signal a possible computer power loss or theft. Hot Plug NIC Installation—Lets you add a new NIC or remove and replace a NIC without turning off power to the computer. Offline Diagnostics—Provides offline diagnostics programs for configuring, testing, and troubleshooting NICs.
CHAPTER 1: INTRODUCTION Load Balancing Load balancing maximizes bandwidth at the server through the use of multiple parallel resilient server links (RSLs) that share the network load. 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.
3CR990 NIC Features 19 failed NIC. The failover behavior of secondary NICs depends on how you set load balancing: ■ In a transmit load balancing arrangement, the primary NIC is the only one that receives packets. If the primary NIC fails, a secondary NIC assumes the configuration profile, network traffic, and active status of the failed primary NIC. ■ In a bidirectional load balancing arrangement, all NICs receive packets.
CHAPTER 1: INTRODUCTION 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. With VLANs, you can define a network according to: ■ Organizational groups—For example, you can have one VLAN for the Marketing department and one for the Finance department. ■ Application groups—For example, you can have one VLAN for e-mail users and one for multimedia users.
3CR990 NIC Features 21 For detailed information on DynamicAccess technology products, go to: http://www.3com.com/dynamicaccess Server Features Using Other NICs One foreign NIC (one that is not a 3Com EtherLink Server NIC) is allowed in one group per server.
CHAPTER 1: INTRODUCTION ■ PCI 2.2-compliant bus or a 3-pin Remote Wake-Up connector on the computer motherboard and a 5-volt standby power supply unit rated at a minimum of 375 milliamperes If you are unsure whether your computer meets the requirements listed above, see the computer documentation or contact the computer manufacturer. For more information on Remote Wake-Up, including a list of computers that currently support this feature, go to: http://www.3com.
3CR990 NIC Features ■ ■ ■ 23 Configure or reconfigure multiple systems simultaneously. Scan for viruses. Back-up hard drives and perform disaster recovery tasks. In addition to firmware, MBA has a complete set of tools, utilities, and pre-OS software that enables network administrators to perform such tasks as: ■ Reconfiguring multiple systems at once. ■ Backing up hard drives automatically.
CHAPTER 1: INTRODUCTION The 3Com DMI Agent consists of a DMI browser with the following components: ■ DMI service layer ■ DMI agent ■ GUI installer ■ NDIS drivers DHCP Server Prevention This feature prevents the PC from acting like a DHCP server. All receive packets are passed through a DHCP filter and are discarded if they are deemed to be destined for the DHCP process. Remote System Alerts The NIC can be configured to continuously transmit a packet to an alert target management station.
DynamicAccess LAN Agent 25 Offline Diagnostics The NIC software includes offline diagnostics programs for configuring, testing, and troubleshooting NICs. The configuration program within the DOS diagnostics program is used for a PC running DOS or NetWare. The 3Com NIC diagnostics program (3Com NIC Doctor) is a windows-based program used for a PC running Windows 2000, Windows NT 4.0, Windows 98, or Windows 95.
CHAPTER 1: INTRODUCTION Windows 2000 Offload Features Additionally, the 3CR990 NIC supports Windows 2000 offload features in an IP environment. The Windows 2000 offload features are designed to enhance the Windows 2000 operating system capabilities by off loading key TCP/IP networking and security tasks from the Windows 2000 operating system: ■ IPSec Offload—reduces CPU utilization by allowing the 3XP processor and a crypto chip on the NIC to perform data encryption operations.

CHAPTER 5: INSTALLING NETWARE CLIENT AND SERVER DRIVERS Maintaining Groups DynamicAccess technology server features allow you to configure load balancing groups. The load balancing features are described in Advanced Server Features on page 17.
Maintaining Groups ■ ■ ■ 105 Decide whether groups are to perform load balancing: ■ Load balancing groups provide failover and share the network load. ■ Resilient server link groups provide failover, but do not share the network load. ■ If you plan to form load balancing/failover groups, do not enable TCP/IP checksum offload. To use bidirectional load balancing, you must assign a dedicated IP address for each load balancing group. This address must be unique (not used elsewhere on the network).
CHAPTER 5: INSTALLING NETWARE CLIENT AND SERVER DRIVERS Figure 7 AUTOEXEC.NCF File for One Group of Three NICs load se load lbrsl ;Define primary NIC slot-frame instances load 3c990 slot=10001 frame=ethernet_802.2 name=p1_802.2 load 3c990 slot=10001 frame=ethernet_ii name=p1_ii ;Define secondary NIC load 3c990 slot=10002 load 3c990 slot=10002 load 3c990 slot=10003 load 3c990 slot=10003 slot-frame instances frame=ethernet_802.2 name=p2_802.2 frame=ethernet_ii name=p2_ii frame=ethernet_802.
Maintaining Groups 107 server links, use the LB option. To specify a resilient server link group without load balancing, use the RSL option. For the LBRSL GROUP command syntax, see Server Feature Commands on page 108. 3 Reboot the server. The sample AUTOEXEC.NCF file in Figure 8 shows one group of three NICs and one group of two NICs. The primary NIC in slot 10001 is bound to two secondary NICs in slot 10002 and slot 10003. The primary NIC in slot 10004 is bound to the secondary NIC in slot 10005.
CHAPTER 5: INSTALLING NETWARE CLIENT AND SERVER DRIVERS Server Feature Commands DynamicAccess server feature commands for NetWare can be used to create sophisticated configurations of groups and for troubleshooting. You can enter them at the NetWare command line or add them to the appropriate NCF file. The commands are summarized below. As shown in the examples, all commands are preceded by the keyword lbrsl.
Maintaining Groups Syntax 109 lbrsl display status [pri_slot] where: pri_slot is the PCI slot number of the primary NIC in the group for which information is to be displayed.
