3CR990 NICS

NIC Overview
The 3CR990 network interface cards (NICs) represent a new generation of secure,
intelligent client NICs with an on-board RISC processor (3XP processor). 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.

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:

I
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:
I

Backing up hard drives automatically.
I
For more information on the management features supported by 3C990 NICs,
access the 3Com World Wide Web site
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:
I
BIOS that supports Remote Wake-Up (power management capability)
5-volt standby power supply unit rated at a minimum of 375 mA
I
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,

CHAPTER 2: 3CR990 NICS
Desktop Desktop Management Interface (DMI) is a network management standard that
Management Interface 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:
I
I

I
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 Softw are,
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.

IP SECURITY
6
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:
Encryption Encryption
Type
Level
medium
high
Description
AH
Authentication only
Authentication and encryption
ESP
Custom
varies
This provides encryption and an extra authentication that includes
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.
Creating a
Security Policy
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.

Troubleshooting a
Netw ork Connection
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).

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 wires 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 are 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.

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.

This section provides information about various network cable standards and
descriptions of those standards for EtherLink 10/100 PCI NICs.
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.
Tw isted-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 Tw isted-Pair The following table shows the five categories of unshielded twisted-pair cable as
Cable Categories defined by the EIA/TIA.
Category
Use
1
2
3
Traditional telephone cable.
Data transmissions up to 4 MHz.
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
5
Voice and data transmission up to 33 MHz. The cable normally has four pairs
of wire. This grade of UTP is not common.
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

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.

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.
