NIC Offload Features
Description
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.
NOTE: Windows 2000 does not allow IPSec offloads and TCP Segmentation offloads for the same session. Though all offload types may
be enabled, TCP Segmentation offloading does not occur during an IPSec session.
IP and TCP Checksum Offload
802.1P Packet Priority Offload
Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the checksum
calculation of TCP/IP and UDP/IP packets.
Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the insertion of
the 802.1Q tag header into the packet.
For more information on enabling and disabling offloads for Windows 2000, see
Remote Wake-Up
Remote Wake-Up provides the ability to remotely power-on a network computer for after-
hours administration. When the PC is in sleep mode (standby state) and receives a wake-
up packet (Magic Packet frame) through the LAN, the NIC turns on the power to the PC.
Remote Wake-Up also requires using a desktop management application that is able to
generate a Magic Packet Remote Wake-Up signal.
If the computer complies with PCI 2.2, Remote Wake-Up is automatically enabled through
the PCI bus.
NOTE: The 3CR990-FX-97 NIC supports only STANDBY state.
Remote Wake-Up Requirements
The following conditions are required to use Remote Wake-Up:
I Management application that supports Remote Wake-Up
I BIOS that supports Remote Wake-Up
I PCI 2.2-compliant bus 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, refer to
the computer documentation or consult the computer manufacturer.
Remote Wake-Up and Multiple NIC Installations
To use multiple NICs as Remote Wake-Up NICs in the same computer, the computer must
have a power supply that can support multiple Remote Wake-Up devices.
Refer to your computer documentation if you are unsure whether your computer power
supply can accommodate more than one Remote Wake-Up device.

Introduction
Integrated Boot ROM with Managed PC Boot Agent (MBA)
The Managed PC Boot Agent (MBA) software adds management capabilities to the NIC
by enabling the computer to boot from a network server, rather than from the computer’s
local drive. MBA is compliant with the Preboot Execution Environment (PXE) specification.
This preboot support allows you to use management applications to perform various tasks
remotely. For example, you can:
I Install and configure a new computer that has never been connected to the network.
I Upgrade software.
I Configure or reconfigure multiple systems simultaneously.
I Scan for viruses.
I Back up hard drives and perform disaster recovery tasks.
For information on configuring the MBA to boot from the network, see “Configuring the
For detailed information on the MBA, refer to the 3Com Managed PC Boot Agent User
Guide, located with the MBA software on the 3Com EtherCD.
Desktop Management Interface (DMI) 2.0
Desktop Management Interface (DMI) is a network-management standard that is widely
accepted for managing Intel-based computers.
DMI 2.0 enables managed computers and net computers to report details about
themselves and their peripheral devices across the network to a DMI 2.0-compliant
management application.
The 3Com DMI Agent allows any DMI management application to access information
such as:
I NIC driver location, version, and size
I Packets-sent statistics
I Cyclic Redundancy Check (CRC) receive errors
A network administrator can then use this type of information to remotely configure and
manage a client or server computer.
The 3Com DMI Agent consists of a DMI browser with the following components:
I DMI service layer
I DMI agent
I GUI installer
I NDIS drivers
For detailed information about the 3Com DMI Agent, refer to the 3Com DMI Agent User
Guide included with the DMI software on the EtherCD. For information about installing
the 3Com DMI Agent and downloading the 3Com DMI Agent User Guide, see

3CR990-FX-97 NIC Features
Remote Control
The 3CR990-FX-97 NIC can also receive commands via Remote Control and Management
Protocol (RMCP). This feature is also specified in the ASF specification and lets network
administrators troubleshoot and resolve system issues across the network. Commands include:
I Power on
I Power off
I Reboot
I Reboot from an alternative device (for example: MBA, CD-ROM, and so forth)
Both monitoring alerts and sending commands are available in the system console
through the 3Com Remote System Alert Manager. This management plug-in is available
for HP OpenView Network Node Manager, Microsoft Systems Management Server, and
Intel LANDesk Client Manager.
Keep-Alive
The 3CR990-FX-97 NIC can also transmit a workgroup keep-alive packet periodically
while the computer is in a sleep state. This packet prevents the computer workstation
address from being aged-out of switch router tables.
Hot Plug NIC Installation
If your computer supports PCI hot plug specifications, you can add a new 3Com NIC or
remove and replace a 3Com NIC without turning off power to the computer. Hot plug
NIC installation allows you to expand connections without taking the computer out of
service. It makes troubleshooting faster and easier because you do not need to wait for
the computer to reboot.
For instructions on performing a hot plug NIC installation, refer to your computer
documentation.
Flow Control Features
The 3CR990-FX-97 NIC uses 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.
7
1
Introduction
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.
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 XP, Windows 2000,
Windows NT 4.0, Windows Millennium Edition (Windows Me), Windows 98, or Windows 95.

Using Windows Offload Features
This chapter provides instructions for enabling offloads in a Windows 2000 environment.
It also describes configuring IPSec offloads in a Windows 2000 environment.
The 3CR990-FX-97 NIC supports offload features for Windows 2000 and Windows XP in
an IP environment. The offload features are designed to enhance the Windows operating
system capabilities by off-loading key TCP/IP networking and security tasks from the
operating system:
NIC Offload Features
Description
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.
NOTE: Windows 2000 does not allow IPSec offloads and TCP Segmentation offloads for the same session. Though all offload types may
be enabled, TCP Segmentation offloading does not occur during an IPSec session.
IP and TCP Checksum Offload
802.1P Packet Priority Offload
Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the checksum
calculation of TCP/IP and UDP/IP packets.
Reduces CPU utilization by allowing the 3XP processor on the NIC to perform the insertion of
the 802.1Q tag header into the packet.
For more information on enabling and disabling offloads for Windows 2000, see
Enabling Offloads
Windows 2000 provides the capability to individually enable or disable each of the four
offload features. (The default setting for these features is enabled.)
To enable or disable individual offload settings in Windows 2000:
1 Right-click the My Network Places desktop icon and select Properties.
The Network and Dial-up Connections screen appears.
2 Right-click the Local Area Connection icon and select Properties.
The Local Area Connection Properties screen appears.
3 Click Configure.
The 3Com NIC screen appears.
4 Click the Advanced tab.
5 Select Enable Offloads in the Property list box.
6 Select the appropriate value in the Value entry box (shown in the following table) for
the desired offload state.
7 Close all open windows.

Configuring Offloads for a Group of Different NICs
Your computer may contain a combination of installed NICs (including one or more 3Com
3CR990-FX-97 NICs 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.
For example, if you have created a group consisting of a 3CR990-FX-97 NIC and another
NIC that does not have any offload capabilities, then the group does not support any
offloads.
In another example, if you have a group of three NICs with two supporting TCP
Checksum, TCP Segmentation, and IPSec offloads, and one supporting only IPSec, then
the group supports only IPSec offloads.
If you add a NIC to an existing group, and that NIC has offload capabilities that differ from
those of the group, then you must reconfigure the group: that is, you must delete the
group, recreate the group, and restart the computer. (If you do not delete and recreate the
group, the Advanced Server software does not bind to the NIC.)
Similarly, if you replace a NIC that has been configured as part of a group with another
NIC that has different offload capabilities, then you must reconfigure the group.
In addition, if you disable or enable any offloads for a group through the Windows 2000
Advanced tab, then you must reconfigure the group.
Configuring IPSec Offloads
The 3CR990-FX-97 NIC performs data-encryption-processing offloads in Windows 2000
and Windows XP environments. The 3CR990-FX-97 NIC does not actually encrypt the
data: the operating system performs that function.
Encryption processing is handled entirely by the 3XP processor on the NIC. The 3XP
processor enables true end-to-end network security at the data capacity of the connected
network cable without sacrificing performance.
Internet Protocol Security (IPSec) is a framework of open standards for ensuring secure
private communications over IP networks. IPSec ensures confidentiality, integrity, access
control, and authenticity of data communications across a public IP network.
32
Configuring IPSec Offloads
Offloading Encryption Processing
You can configure any two (or more) computers running Windows 2000 or Windows XP
to perform IPSec encryption by changing the Local Security Setting in the operating
system. With most non-3CR990-FX-97 NICs, all the IPSec processing is done by the host
central processing unit (CPU), which significantly diminishes CPU performance. The
3CR990-FX-97 NIC can offload all the encryption processing from the host CPU, thereby
freeing the CPU to work on other tasks. The data-encryption offload capability of the
3CR990-FX-97 NIC is enabled at the factory.
For any two or more computers running operating systems other than Windows 2000 or
Windows XP (that is, Windows 95/98/Me/NT), IPSec encryption is provided by third-party
applications. The 3CR990-FX-97 NIC does not provide IPSec encryption offloading for
those operating systems.
Auto-Selecting Basic or Strong Encryption Processing
The 3CR990-FX-97 NIC provides Data Encryption Standard (DES) 56-bit basic encryption
processing and 3DES (3DES 168-bit) strong encryption processing. DES and 3DES are IPSec
bulk encryption algorithms for coding data. DES encrypts 64-bit data blocks using a 56-bit
key. DES can be applied in several modes. 3DES (Triple DES) achieves a higher level of
security by encrypting the data three times using DES with three different, unrelated keys.
3DES is also known as 168-bit data encryption.
There is no need to configure the 3CR990-FX-97 NIC to establish a particular encryption
setting: the NIC auto-selects the strongest encryption setting based on the data
encryption setting of the partner (receiving or sending) node. If the partner node has a
3DES encryption setting, the NIC automatically processes data encryption using the 3DES
standard; if the partner node has a DES encryption setting, the NIC automatically
processes data encryption using the DES standard; if the partner node has no encryption
setting, the NIC automatically processes data in unencrypted form.
Configuring IPSec for Windows 2000
The 3CR990-FX-97 NIC accelerates IP security (IPSec) data encryption from supported
operating systems that provide this offload capability. This feature is currently available in
the Windows 2000 and Windows XP operating systems.
IPSec primarily consists of two parts:
I encryption/decryption
I authentication
To send or receive encrypted data in a PC running Windows 2000 with a
3CR990-FX-97 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.

Using Windows Offload Features
The following table shows the available levels of encryption:
Encryption

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, refer to the Microsoft documentation about
creating IPSec flows.

The process you use to create and enable a security policy depends on your network
environment requirements. The following is an example of one approach to creating a

NOTE: To upgrade the NetWare driver, you must create installation diskettes from
the EtherCD that accompanied this product. Use these diskettes to install the
Netware driver. See “Creating Installation Diskettes” on page 11.
NetWare Driver Installation Requirements
Before you install software, verify that the installed NICs are functional or change their
configuration settings by running DOS diagnostics. Use the 3C99XCFG.EXE program
located on the EtherCD.
The instructions in this section describe how to set up a sample server configuration.
Setting up your own configuration may require a slightly different sequence of tasks and
different numbers of NICs.
If you are installing the software during the installation of the network operating system,
For a list of additional installation requirements, see “Installation Requirements” on
Netware Packet Receive Buffers
Follow these installation guidelines for packet receive buffers:
I The driver requires 200 packet receive buffers for each installed NIC.
I You must increase the minimum and maximum packet receive buffers values by 200
for each installed NIC.
For example, if you install two NICs, increase the parameters in the STARTUP.NCF file
by 400 as follows:
Before installing NICs
SET MINIMUM PACKET RECEIVE BUFFERS = 1000
SET MAXIMUM PACKET RECEIVE BUFFERS = 2500
SET MINIMUM PACKET RECEIVE BUFFERS = 1400
SET MAXIMUM PACKET RECEIVE BUFFERS = 2900

Installing and Configuring the NetWare Driver
Slot Numbers for Multiple NICs
If you are installing more than one NIC on a server, you must know which NIC corresponds
to a given PCI slot to connect a cable from the NIC to the appropriate port on the hub or
switch. You can correlate slots with physical NICs by the NIC MAC addresses. (The MAC
address is written on a bar code label on the top component side of the NIC.)
Obtaining Slot Numbers
The NetWare driver installation program requires you to enter a PCI slot number for each
NIC. In older versions of NetWare software, the term slot number referred to the physical
slot in which the NIC was installed in the server. Now, the slot number is a combination of
the bus number, bus type, and physical slot number. The value of a slot number can be
10001 or larger.
Follow this procedure to obtain slot numbers for a multi-NIC installation:
2 Follow the installation instructions in this chapter to load the EtherCD, copy the driver,
and load the driver.
3 In the NetWare Console, issue a CONFIG command.
4 Record the slot number listed for the installed NIC.
5 Install the second 3CR990-FX-97 NIC.
6 Follow the installation instructions in this chapter to install the driver on the second NIC.
Each time you load the driver, the CONFIG command displays the slot numbers for all
the 3CR990-FX-97 NICs in the system.
Installing the NetWare Driver
To install the NetWare driver:
1 Copy the MSM.NLM, ETHERTSM.NLM, and NBINLM files from the \NWSERVER
directory on the EtherCD to the directory on your hard drive where other NLM files
are located; or use the latest service pack from Novell.
NOTE: Copy the NLM files only if the versions existing on the server are older than
the versions supplied on the EtherCD.
The NLM file location is typically in the SYS:SYSTEM directory. You need a NetWare
client system to copy the NLM files to the server.
2 Copy the LAN driver file (3C99X.LAN) from the EtherCD to the same directory.
3 Add the following two lines to the AUTOEXEC.NCF file:
load sys:\system\3c99x.lan slot=<slot> NAME=<name>
FRAME=<frametype>
bind ipx to <name> net=<number>
NOTE: If you copy the NLM files to a different directory, you must specify the path
in the preceding LOAD statement.
4 Save and exit the file, and then reboot the server.

to the following format:
load 3C99X.LAN slot=<slot1> NAME=<name1> FRAME=<frametype1>
bind ipx to <name1> net=<net1>
load 3C99X.LAN slot=<slot2> NAME=<name2> FRAME=<frametype2>
bind ipx to <name2> net=<net2>
The values <slot1> and <slot2> are the numbers of the PCI slots in which the NICs are
physically installed. To view the numbers of these PCI slots, use the 3Com Configuration
and Diagnostic program for DOS. See “Verifying the PCI Slot Number” below
for instructions.
The values <name1> and <name2> are unique names assigned to each NIC by your
system administrator. The values <name1> and <name 2> must be different.
The frame parameters <frametype1> and <frametype2> can be one of the following:
I Ethernet_802.2
I Ethernet_802.3
I Ethernet_II
I Ethernet_SNAP
Make sure the frame type for the server and the workstation is the same. For example, if
the server uses Ethernet_802.2, the workstation must also use Ethernet_802.2.
The values <net1> and <net2> are unique numbers assigned by the system administrator
to each NIC. Make sure <net1> and <net2> are different numbers.
Refer to the appropriate Novell NetWare manuals for further information.
Verifying the PCI Slot Number
To verify the PCI slot number in which a NIC is installed:
1 Boot the NetWare server with the -na option.
This option prevents the AUTOEXEC.NCF file from loading. For example, enter:
server -na
2 Issue the load command for the NIC LAN driver without a slot parameter.
For example, enter:
load sys:\system\3c99x.lan

Installing the 3Com DMI Agent
This appendix explains how to install the 3Com Desktop Management Interface (DMI)
Agent on your PC. The 3Com DMI Agent allows any DMI-compatible browser or network
management application that supports DMI 2.0 to remotely manage and configure
advanced features of a 3CR990-FX-97 NIC.
NOTE: For detailed information about the 3Com DMI Agent, refer to the 3Com
DMI Agent User Guide included with the DMI Agent software on the EtherCD.
About the 3Com DMI Agent
The 3Com DMI Agent allows you to obtain basic NIC information, including:
I Node address
I MAC address
I Driver version
Additionally, depending on the features of your NIC, the 3Com DMI Agent allows you to
view and configure advanced NIC features, including:
I Managed PC Boot Agent (MBA) software
I Remote Wake-Up events
I Workgroup keep-alive packet
Each PC that contains a 3CR990-FX-97 NIC and the 3Com DMI Agent generates a
Management Information Format (MIF) file that contains information about the PC and
the NIC. DMI applications use the information from the MIF to manage the PC and
the NIC.
The content of the MIF is based on the capabilities of the NIC driver found in the PC. For
example, if a NIC with an MBA boot ROM is found, all groups related to the boot ROM
are included in the MIF for that particular NIC. This feature ensures that the network
management application does not receive irrelevant information for the NIC.
For a description of each MIF supported by the 3Com DMI Agent, refer to the 3Com DMI
Agent User Guide included with the 3Com DMI Agent software on the EtherCD.
