3CR990 NICS

NIC Overview The 3CR990 network interface cards (NICs) repr esent a new generation of secure,

intelligent client NICs with an on-board RISC processor (3XP pr ocessor). The RISC processor is designed to optimize system and network performance. Optimization occurs by ofﬂoading key networking and security tasks even when running bandwidth-intensive applications such as voice, video, imaging, and Internet and intranet applications. These NICs connect your PCI-compliant PC to a 10 Mbps or 100 Mbps Ethernet network and provide advanced features for high performance and secure transactions.

The 3CR990 NICs provide up to 3DES (Data Encryption Standard 168-bit) encryption. Encryption processing is handled entirely by the RISC processor and the encryption chip that reside on the 3CR990 NICs.

The onboard encryption chip enables true end-to-end network security (IPSec) at the data capacity of the connected network cable (wire speed), without sacriﬁcing performance.

3XP processor

3CR990 NICs support up to 168-bit (3DES) encryption

NIC Features The 3CR990 NICs provide these features for supported IP and IPX environments:

■ Integrated Boot ROM

■ Remote Wake-Up

■ Desktop Management Interface (DMI)

■ DHCP server prevention

■ Broadcast storm limitation

■ Ofﬂine diagnostics

Integrated Boot ROM Managed PC Boot Agent (MBA) software provides the multiprotocol preboot

ﬁrmware and tools. MBA adds management capabilities to the NIC by enabling the PC to boot from a network server, rather than from its local drive. 3CR990 NICs have an integrated boot ROM already installed on the NIC.

For information on conﬁguring and using the MBA, see the Managed PC Boot Agent (MBA) User Guide located on the EtherCD. Navigate the following path: CD ROM drive letter \ Installs \ Mba \ Manual, and then double-click 3ComGuide.exe to unzip the compressed user guide ﬁle.

NIC Features 17

MBA preboot support allows you to use management applications to perform tasks such as:

■ Installing and conﬁguring a new PC that has never been connected to

the network.

■ Upgrading software.

■ Scanning for viruses.

■ Performing 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 tasks such as:

■ Reconﬁguring multiple systems at once.

■ Backing up hard drives automatically.

For more information on the management features supported by 3C990 NICs, access the 3Com World Wide Web site

Go to: http://www

.3com.com/managedpc.

Remote Wake-Up Remote Wake-Up provides the ability to remotely power-up a network PC.

When the PC is in sleep mode and receives a wake-up packet (Magic Packet frame) through the LAN, the NIC turns on the power to the PC. To use the Remote Wake-Up feature, a desktop management application is also required that is able to generate a Magic Packet Remote Wake-Up signal.

NOTE: The 3CR990 NICs provide a network connection with or without the Remote Wake-Up cable installed.

Your PC or server must be either 2.1 or 2.2 PCI speciﬁcation-compliant to use Remote Wake-Up. A PC that meets the PCI 2.1 speciﬁcation uses the 3-pin Remote Wake-Up connector on the PC motherboard. A PC that meets the PCI 2.2 speciﬁcation uses the PCI bus on the motherboard to handle Remote Wake-Up. (A 3-pin connector is not provided on the motherboard.)

Additionally, to support Remote Wake-Up, a PC must have a:

■ BIOS that supports Remote Wake-Up (power management capability)

■ 5-volt standby power supply unit rated at a minimum of 375 mA

If you are unsure whether your PC meets the requirements listed above, refer to your PC documentation or contact your PC manufacturer. For more information on Remote Wake-Up, including a list of PCs that currently support this feature, access the 3Com World Wide Web site

Go to: http://www

.3com.com/partners/acpi.

18 CHAPTER 2: 3CR990 NICS

Desktop

Management Interface

Desktop Management Interface (DMI) is a network management standard that is widely accepted for managing Intel-based computers. The 3Com DMI Agent allows any DMI management application to access information such as the NIC driver location, version, and size; packets sent statistics; crc receive errors; and much more.

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.

Broadcast Storm Limitation

Broadcast throttling is implemented on both the transmit and receive data streams. The user can specify a transmit broadcast threshold as a percentage of the transmit bandwidth. The adapter monitors each data stream and discards any broadcast or multicast packets that exceed this limit.

To install DMI, on the EtherCD Welcome screen, click NIC Software,

DynamicAccess Technology, and Install 3Com DMI Agent now.

Ofﬂine Diagnostics This product provides ofﬂine diagnostics programs for conﬁguring, testing,

and troubleshooting 3CR990 NICs. The conﬁguration program within the DOS diagnostics program is used for a PC running Windows 2000, Windows NT 3.51, or DOS. The 3Com NIC diagnostics program (3Com NIC Doctor) is a windows-based program used for a PC running Windows 98, Windows 95, or Windows NT 4.0.

Windows 2000 Ofﬂoad Features

Additionally, the 3CR990 NICs support windows 2000 ofﬂoad features in an IP environment. The 3CR990 NIC Windows 2000 ofﬂoad features are designed to enhance the Windows 2000 operating system capabilities by ofﬂoading 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.

■ TCP Segmentation Ofﬂoad—reduces CPU utilization by allowing the

3XP processor on the NIC to perform segmentation of TCP packets

■ IP and TCP checksum Ofﬂoad—reduced CPU utilization by allowing the

3XP processor on 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

3XP processor on the NIC to perform the insertion of the 802.1Q tag

header into the packet

from loading.) Example:

server -na

2 Issue the load command for the NIC LAN driver without a slot parameter.

Example:

load c:\nwserver\3c99x.lan

3 NetWare will list the valid slot number(s) for the NIC, depending on how many

NICs are installed. The values appearing in the list are the slot values that you should use.

Example: After you issue the command, a message appears. At the end of the message,

additional text similar to the following appears:

Total of 2 3C99x PCI adapter card(s) found. Supported slot values are 2,3. Slot:2

IP SECURITY

Overview The 3CR990 NICs accelerate IP security (IPSec) data encryption from supported

operating systems that provide this ofﬂoad capability. This feature is currently

available in the Microsoft Windows 2000 operating system.

IPSec consists of two parts: encryption/decryption and authentication. To send

or receive encrypted data in a PC running Windows 2000 with a 3CR990 NIC

installed, you must ﬁrst create a security policy, and then enable encryption on

the NIC. The security policy establishes and deﬁnes how encrypted network trafﬁc

between your PC and a speciﬁed server occurs.

Authentication enables the receiver to verify the sender of a packet by adding key

ﬁelds to a packet without altering the packet data content.

The following table shows the available levels of encryption:

Creating a Security Policy

Encryption Type

AH medium Authentication only ESP high Authentication and encryption Custom varies This provides encryption and an extra authentication that includes

The process you use to create and enable a security policy will depend on your

network environment requirements. The following is an example of one approach

to creating a security policy.

NOTE: You must complete all of the sequences in this section to establish and enable a security policy for transmitting and receiving encrypted data over the network.

Encryption Level

Description

the IP header. Custom allows you to select options for both AH and ESP, such as

MD%/SHA-1 and DES/3DES. And you can select the rate at which new keys are negotiated.

Microsoft uses IKE key exchange to renew keys every x seconds or y bytes. However, this practice is computationally very high in overhead. Some users may set these values low and have frequent key updates. Users more concerned with performance will set these values higher.

For more information, see the Microsoft documentation about creating IPSec flows.

When working with 10BASE-T or 100BASE-TX cabling, concentrators, and NICs from different vendors, it is possible to connect everything but still have no network communication.

To narrow the range of possible causes of common network connection problems:

1 Determine whether your equipment complies with the 10BASE-T or

100BASE-TX standard. This is particularly important for data concentrators (hubs or repeaters).

.knowledgebase.3com.com.

64 CHAPTER 9: TROUBLESHOOTING

2 Connect a straight-through cable from the PC to the hub.

The hub performs an internal crossover so that the signal can go from TD+ to RD+ and TD– to RD–. When you look at an RJ-45 connector from the front (that is, the opposite side from where the wir es enter the connector), pin 1 is identiﬁed on the right side when the metal contacts are facing up.

3 Make sure that the TD+ and TD– wires ar e twisted together, and that the RD+ and

RD– are twisted together. Using wires from opposing pairs can cause signals to be lost.

Troubleshooting Hubs A crossover cable can be used to identify the type of failure when hub

performance or connectivity is in question. To use a crossover cable:

1 Connect a ﬁle server and a client PC back-to-back with a crossover cable to verify

that the NIC and network operating system are properly conﬁgured.

2 To make a crossover cable, connect TD+ to RD+ and TD– to RD–.

The cable performs the crossover that is usually performed by the hub.

Cabling Pinouts The following illustration compares the cabling pinouts for straight-through and

crossover cables.

If the ﬁle server and client PC function together as a small network, then either the existing cabling or the hub is failing.

When a crossover cable is used, the LED on the NIC functions differently than it would under normal operating conditions. For example, with a correct crossover connection, the LED lights, whereas with a straight-through connection, the LED does not light. If you make a crossover cable and the polarity is mismatched (that is, TD+ to RD– instead of TD+ to RD+), the LED blinks.

Cabling Requirements The cable type, quality, distance, and connectors must comply with the

Electronic Industries Association/Telecommunications Industries Association (EIA/TIA) 568 Commercial Building Wiring Standard and the Technical Services Bulletin TSB38 standards.

Twisted-Pair Cable Twisted-pair cable consists of copper wires surrounded by an insulator. Two wires

are twisted together (the twisting prevents interference problems) to form a pair, and the pair forms a circuit that can transmit data. A cable is a bundle of one or more twisted pairs surrounded by an insulator.

Unshielded twisted pair (UTP) is the most commonly used type of twisted-pair cable. Shielded twisted pair (STP) provides protection against crosstalk. Twisted-pair cable is now commonly used in Ethernet, Fast Ethernet, and other network topologies.

Unshielded Twisted-Pair

Cable Categories

The following table shows the ﬁve categories of unshielded twisted-pair cable as deﬁned by the EIA/TIA.

Category Use

1 Traditional telephone cable. 2 Data transmissions up to 4 MHz. 3 Voice and data transmission up to 25 MHz. The cable typically has four pairs

of wires. Category 3 is the most common type of installed cable found in older corporate wiring schemes.

4 Voice and data transmission up to 33 MHz. The cable normally has four pairs

of wire. This grade of UTP is not common.

5 Voice and data transmission up to 125 MHz. The cable normally has four pairs

of copper wire and three twists per foot. Category 5 UTP is the most popular cable used in new installations.

10BASE-T Description 10BASE-T is the Institute of Electrical and Electronics Engineers (IEEE) 802.3

standard for Ethernet signaling over unshielded twisted-pair wire at 10Mbps. Ethernet, as the most widely used network protocol, uses 10BASE-T as its primary

cabling scheme. Ethernet characteristics include:

■ A data rate of 10 Mbps

■ A broadcast architecture

■ A speciﬁc media-access control (MAC) scheme

The 10BASE-T name indicates a signaling speed of 10 Mbps and twisted-pair wiring. Base stands for baseband, which denotes a technique for transmitting signals as direct-current pulses rather than modulating them onto separate carrier frequencies.

A wiring topology using 10BASE-T speciﬁes a wiring hub, cable arranged in a star conﬁguration, and unshielded twisted-pair cable. Each node has a separate cable run that must not exceed 328 ft. (100 meters) from the node to the hub.

100BASE-TX Description 100BASE-TX is the IEEE 802.3u standard for Fast Ethernet signaling over

Category 5 UTP or STP wire at 100Mbps. Based on an extension to the IEEE 802.3 Ethernet speciﬁcation, Fast Ethernet

characteristics include:

■ A data rate of 100 Mbps

■ A broadcast architecture

■ A speciﬁc media-access control (MAC) scheme

A wiring topology using 100BASE-TX speciﬁes a wiring hub, cable arranged in a star conﬁguration, and Category 5 UTP or STP wiring. Each node has a separate cable run that must not exceed 328 ft. (100 meters) from the node to the hub.

The following ﬁgure shows the pin layout for the RJ-45 connector socket on the NIC backplate.

68 APPENDIX A: SPECIFICATIONS

Flow Control The 3CR990 NICs utilize ﬂow control technology to throttle the incoming

data packet stream and prevent the loss of packets. IEEE 803.2x ﬂow control prevents the input buffers of a device from overﬂowing. By using pause frames to communicate buffer status between linked transmitting and receiving devices (transmitters and receivers). A receiver sends a pause frame to tell a transmitter to stop the transmission of data frames for a speciﬁed period, allowing the receiver’s input port buffers to empty before receiving new packets.

Pause Frames When a transmitter receives pause frames, it suspends transmission for the

speciﬁed period. When the receiver’s input buffers can store packets again, it can either send another pause frame to tell the transmitter to resume transmission, or wait for transmission to resume at the end of the speciﬁed period.

With asymmetric ﬂow control, only one of two linked devices can receive pause frames. With symmetric ﬂow control, both linked devices can send and receive pause frames.

Link Negotiation Related to ﬂow control is the auto-negotiation capability, in which linked devices

advertise their ﬂow control capabilities and automatically select the best common mode of communication.

Rare cases (for example, linking to a device that does not support auto-negotiation) may require that auto-negotiation be disabled on a port, thereby enabling forced link on that port. When forced link is enabled, linked devices must have matching ﬂow control capabilities. For example, a port that is set for forced link and reception ﬂow control can connect successfully only with a port that is set for forced link and transmission ﬂow control.
