Installing and Configuring 10/100Base-TX/9000
Introduction
Introduction
The HP-PB 10/100Base-TX/9000 product provides the means for
interfacing various types of HP 9000 Series 800 computers to either a
10Base-T or 100Base-TX network. Refer to the Release Notes for the list
of supported systems.
100Base-TX is a subset of 100Base-T networking defined by the IEEE
802.3u-1995 standard. 100Base-TX provides 100 Mbit/s data
transmission over category 5 unshielded twisted-pair (UTP) cable. Two
pairs of wires in the cable are used--one wire pair is for receiving data,
and one wire pair is for transmitting data. The same card port that
supports 100Base-TX operation can also support 10Base-T operation.
IEEE 802.3u 100Base-TX LANs have topologies very similar to 10Base-T
LANs; however certain aspects of the topology such as the maximum
permitted cable lengths are more stringent for 100Base-TX than for
10Base-T. The category 5 UTP cable used in 100Base-TX networks
between devices such as an HP computer and a 100Base-TX hub must be
less than 100 meters long.
For more information on network topologies and associated specifications
for 100Base-TX networking, refer to the IEEE 802.3u specification. Also,
a useful practical reference is Fast Ethernet, Dawn of a New Network by
Howard W. Johnson (published 1996 by Prentice Hall PTR, Upper Saddle
River, New Jersey 07458. Phone 800-382-3419. The ISBN number is
0-13-352643-7).
Announcements
There are no changes in the way the HP-PB 10/100Base-TX/9000 LAN
card works for this release. As of June 1999, the product has a new
product number: A3495A. This release supports the ability to change
speed and duplex mode in the System Admin Manager (SAM). This
release also provides upport for MTU size setting/resetting using
lanadmin -[m|M|R].

Compatibility and Installation Requirements
Compatibility and Installation Requirements
Following are the compatibility requirements of the HP-PB
10/100Base-TX/9000:
• The HP-PB 10/100Base-TX/9000 card supports autonegotiation and
autosensing. You should not normally need to manually configure the
speed, autonegotiation, or duplex mode of the card. If your switch does
not support autonegotiation but is set to full-duplex mode, there may
be a mismatch between the card and the switch, because the card
defaults to half-duplex for switches that do not support
autonegotiation. You can determine what the card is set to using
lanadmin -x and reset it if necessary using lanadmin -X. See
“Manual Speed and Duplex Mode Configuration” for details.
• Both full- and half-duplex modes are supported. Ensure that your
hub or switch is set to the desired duplex mode.
• The HP-PB 10/100Base-TX/9000 LAN software is for use with only
the following protocols: TCP/IP, UDP/IP, ARPA, NFS, and Advanced
Server/9000.

Compatibility and Installation Requirements
Manual Speed and Duplex Mode
Configuration
Because the HP-PB 10/100Base-TX/9000 card supports autonegotiation,
you should not normally need to manually set the duplex mode.
Sometimes you may need to manually set the duplex mode of the
card--for example, if the switch is operating at full duplex but does not
autonegotiate. Because the card defaults to half-duplex when
autonegotiation is turned off, this could cause a mismatch between the
card and switch (at either 10 or100 Mbits/s). To fix this, use the
lanadmin -X command as described later in this section.
The CSMA/CD media access method used in IEEE 802.3u-1995 is
inherently a half-duplex mechanism. That is, at any one time, there can
be only one sender of data on the link segment. It is not possible for
devices on either end of the link segment to transmit simultaneously.
Since Category 5 UTP contains multiple pairs of wires, it is possible to
have devices on both ends of a link segment sending data to each other
simultaneously. This is known as full-duplex operation. While the details
of full-duplex operation are not currently defined by IEEE 802.3u-1995
(full-duplex mode essentially involves “turning off” the CSMA/CD access
method which is the foundation of IEEE 802.3), the autonegotiation
mechanism defined in IEEE 802.3u-1995 allows devices to advertise and
configure themselves to operate in a full-duplex mode which is
essentially vendor-specific. Devices that do not support autonegotiation
can sometimes be manually configured to operate in full-duplex mode.
Full-duplex mode is most commonly found in, and indeed only makes
sense for, switches rather than hubs. It may be found in either 10 Mbit/s
or 100 Mbit/s switch devices. Full-duplex mode may provide a
throughput advantage under some circumstances, the degree of the
advantage is application-dependent.
The HP-PB 10/100Base-TX card supports both half and full-duplex
operation.
Ensure that the speed, duplex mode, and autonegotiation of the
associated switch are configure the same as on the HP-PB
10/100Base-TX card. If the switch supports autonegotiation on the ports
connected to the cards, this should be enabled as explained in the section
in this release note called “Autonegotiation and Autosensing.”

13
Installing and Configuring 10/100Base-TX/9000
Compatibility and Installation Requirements
To list the current speed and duplex mode of the HP-PB
10/100Base-TX/9000 card, use the -x option (NOTE: lowercase x) of the
lanadmin command. Determine the speed and duplex mode of your hub
or switch before performing manual configuration as follows:
lanadmin -x ppa (HP-UX 10.30 or 11.0)
lanadmin -x nmid (HP-UX 10.20)
To manually set the duplex mode of the interface, install one of the
patches above and then use the -X option of lanadmin as follows:
lanadmin -X mode ppa (on HP-UX 10.30 and 11.0)
lanadmin -X mode nmid (on HP-UX 10.20)
where
:mode can be any one of the following strings (and the fd or hd are
case-insensitive):
10fd =10 full-duplex
10hd =10 half-duplex
100fd =100 full-duplex
100hd =100 half-duplex
and
lanadmin -X auto_on ppa (turns autonegotiation on for HP-UX 10.30
and 11.0)
lanadmin -X auto_on nmid (turns autonegotiation on for HP-UX 10.20)
The ppa is the physical point of attachment on HP-UX 10.30 or 11.0. On
HP-UX 10.20, use the nmid or Network Management ID of the card. You
can get the ppa (nmid) from the output of the lanscan command.
Example:
If the ppa (nmid on HP-UX 10.20) of the 100Base-TX interface is 5, the
command to set the card to 10Mbits/s and full-duplex mode would be:
lanadmin -X 10fd 5
After issuing the lanadmin -X, you must wait at least 11 seconds before
attempting to use the specified network interface.
If you want the duplex mode setting to be effective in all subsequent
reboots, you must enter the information in the following file:
/etc/rc.config.d/hpBasetconf
14
Chapter 1
Installing and Configuring 10/100Base-TX/9000
Compatibility and Installation Requirements
Manually configuring the speed or duplex setting of a switch port on
some switches may disable that switch port from doing autonegotiation.
Verify that both the card and the switch port are operating in the same
speed and duplex mode as desired.
If you use manual configuration to change the card to a different speed
and duplex mode, you may need to turn autonegotiation on first before
the manual setting takes place.
Mismatches between the speed, autonegotiation, or duplex mode of the
card and switch will cause incorrect operation.
Specific items for each installed 10/100Base-TX interface card can be
configured by creating an array of variables, where each array index
corresponds to one interface card; refer to the existing contents of the
hpBasetconf file for more detail. For each 10/100Base-TX interface card
whose duplex mode is to be set, entries of the following form must be
made in the hpBasetconf file:
HP_BaseT_INTERFACE_NAME[n]=NameUnit
HP_BaseT_SPEED[n]= [10HD 10FD 100HD 100FD auto_on]
NameUnit is the name of the interface to be configured, which can be
determined from the output of the lanscan command. n is the array
index which should start at 0 but which itself bears no relation to specific
interfaces.
For example, if the name of the 10/100Base-TX interface to configure as
shown by lanscan is lan3, and this is the only interface to be configured,
the entries in the hpBasetconf file to “permanently” configure this
interface to full duplex mode across system reboots would be:
HP_BaseT_INTERFACE_NAME[0]=lan3
HP_BaseT_SPEED[0]=[10FD 100FD auto_on]
If there were a second 10/100Base-TX interface with the name of lan4 on
the system whose duplex mode were also to be “permanently” configured
to full-duplex, the additional entries in the hpBasetconf file would be:
HP_BaseT_INTERFACE_NAME[1]=lan4
HP_BaseT_SPEED[1]=[10FD 100FD auto_on]
To determine the current duplex mode of the card, use the -x option of
the lanadmin command as explained earlier.

Compatibility and Installation Requirements
Autonegotiation and Autosensing
Autonegotiation is a mechanism defined in the IEEE 802.3u specification
whereby devices sharing a link segment can exchange information and
automatically configure themselves to operate at the highest capability
mode shared between them.
Autonegotiation is like a rotary switch that automatically switches to the
correct technology such as 10Base-T or 100Base-TX or between half- and
full-duplex modes. Once the highest performance common mode is
determined, auto-negotiation passes control of the link to the
appropriate technology, sets the appropriate duplex mode, and then
becomes transparent until the link is broken.
Following is the IEEE 802.3u-defined hierarchy for resolving multiple
common abilities for a 10/100Base-TX card. The HP-PB
10/100Base-TX/9000 product provides the means for interfacing various
types of HP 9000 workstations to either a 10Base-T or 100Base-TX
network. 100Base-TX is a subset of 100Base-T networking defined by the
IEEE 802.3u-1995 standard. 100Base-TX provides 100 Mbit/s data
transmission over category 5 unshielded twisted-pair (UTP) cable. Two
pairs of wires in the cable are used—one wire pair is for receiving data,
and one wire pair is for transmitting data. The same card port that
supports 100Base-TX operation can also support 10Base-T operation.
• 100Base-TX half duplex
• 10Base-T full duplex
• 10Base-T half duplex
• 100Base-TX full duplex
For example, if both devices on the link support 10Base-T (half duplex)
and 100Base-TX (half duplex), autonegotiation at both ends will connect
the 100Base-TX (half duplex) instead of the 10Base-T (half duplex).
Most Fast Ethernet devices on the market today such as hubs and
switches do not support autonegotiation. Either the speed and duplex
mode of the device are fixed (as is usually the case with hubs), or they are
often manually configured at the desired speed and duplex (as is often
the case for switches). However, switches that support autonegotiation
are starting to be offered.
If the HP-PB 10/100Base-TX/9000 card is connected to a device, such as
16
Chapter 1
Installing and Configuring 10/100Base-TX/9000
Known Problems and Workarounds
a switch, that is autonegotiating, the HP-PB card will autonegotiate with
the device to mutually determine the highest possible speed and duplex
settings between them.
NOTE
If the HP-PB 10/100Base-TX/9000 card is connected to a device that
does not support autonegotiation or a device that has autonegotiation
disabled, the HP-PB card will autosense the speed of the link and set
itself accordingly. The duplex mode of the card will be set to
half-duplex in this case. If you want the card to operate in full-duplex
mode, you have to set it using the method described in “Manual Speed
and Duplex Mode Configuration.”
The HP-PB 10/100Base-TX card will sense when the connection between
itself and a hub or switch on the other end of a link has been broken. If a
connection is made to another (or the same) device, the autonegotiation
and autosensing process will be done again automatically.
Autonegotiation and autosensing are also done whenever the interface is
reset.
Known Problems and Workarounds
If your switch supports autonegotiation, you should not normally need to
set the duplex mode or the speed of the HP-PB 10/100Base-TX card.
Optionally, you can set the full- or half-duplex mode of the card by using
the lanadmin -X mode ppa (nmid) command as explained in “Manual
Speed and Duplex Mode Configuration” in this Release Note.
NOTE
You cannot set the mode of the card in SAM (the field in SAM that
contains the setting for full-duplex is ignored--it may show the MAC
address of the card but cannot be used for configuration).

What Happens During Card Initialization Sequence?
What Happens During Card Initialization
Sequence?
Following is an overview of the initialization sequence for the HPPB
10/100Base-TX card:
Initialization of an HP-PB 10/100Base-TX card happens during system
bootup only, and it is driven by the btlan1 driver for the card. The card
consists of two boards: the motherboard and the daughterboard.
Initialization is divided into two phases: initialization of the
motherboard and initialization of the daughterboard. The initialization
of each of these boards is further divided into the initialization of each of
the major programmable components on the boards. Initialization
consists of the following sequential tasks: identification of a component,
resetting a component, if applicable, and configuration.
Two LEDs on the card are related to the proper installation and
functioning of the card: the Power and Test LEDs. None of the
components on either of the boards is identifiable if the power does not
reach the card, in which case the Power LED on the card does not light.
The card might not be seated properly in this case. Even if the Power
LED is lit, some of the components could still fail to identify correctly if
the card is not properly seated or if the card is defective. In such a case
the initialization of that component fails to complete and the Test LED
on the card is lit. In one case, the component on the motherboard which
is responsible to drive the Test LED may be defective or may not be
reached due to the improper seating of the card in which case the
initialization aborts without lighting the Test LED. However, whenever
initialization fails, it prints a message on the console identifying the
failure. You can later retrieve initialization messages after the system is
fully booted up by using the dmesg command.
Finally, the driver tries to establish a good data link between the card
and the hub or switch. If there is no cable connection, or if the cable
connection is bad, or if the hub or switch is not compatible, that is, not
10Base-T or 100Base-TX capable, the Link LED will not be lit and either
10Base-T LED or 100Base-TX LED will be lit at random. In this
situation, the Test LED will not be lit. Also, a message indicating the
detection of a bad cable connection is printed on the console as well as
logged in NETTL logs.

• Save all network log files. Make sure that ERROR and DISASTER
log classes are enabled when log files are collected.
Prepare the formatted output and a copy of the log file for your HP
representative to further analyze.
• Prepare a listing of the HP-UX I/O configuration you are using for
your HP representative to further analyze. Use the ioscan(1M)
command to help collect this information
• Try to determine the general area within the software where you
think the problem exists. Refer to the appropriate reference manual
and follow the guidelines on gathering information for that product.
• Document your interim, or “workaround,” solution. The cause of the
problem can sometimes be found by comparing the circumstances in
which it occurs with the circumstances in which it does not occur.
• Create copies of any Internet or 10/100Base-TX/9000 link trace files
that were active when the problem occurred for your HP
representative to further analyze.
• In the event of a system failure, a full memory dump must be
taken. Use the HP-UX utility savecore(1M) to save a core dump.

Troubleshooting Overview
Troubleshooting Overview
10/100Base-TX problems can be caused by problems in a variety of
hardware and software components. The problem impacting your system
may originate in another part of the 10/100Base-TX network.
As with any troubleshooting, a systematic approach is helpful. The
following two tables and the following flowcharts provide a logical
sequence of steps to follow when troubleshooting 10/100Base-TX/9000.
Using the diagnostic flowcharts provided in this chapter, identify
whether the problem is with 10/100Base-TX/9000 or any of the
connections to the hub or switch, or whether it is in some other part of
the network, verify your assumptions and, if it is limited to
10/100Base-TX/9000 software or hardware, correct the problem.
NOTE
To quickly isolate and diagnose 10/100Base-TX/9000 problems, follow the
steps in the troubleshooting flowcharts, beginning with Flowchart 1, and
stay with the flowcharts until the problems are resolved. Continue
sequentially through flowcharts 2, 3, 4, 5, 6, and 7, referring back to
flowchart 1 (ping) until you have corrected the problems.
If you cannot solve the problem on your own, contact your HP
representative. Use the guidelines at the end of chapter 3 to help you
effectively communicate what is wrong. T he 10/100Base-TX product
uses diagnostic tools compatible with the HP LAN/9000 Link product.
Table 4-1
Troubleshooting Information
Symptom
Corrective Action
The system does not recognize the
card; the HP-PB Test LED is off.
Ensure that the card is seated in the
system backplane. Check for boot-time
error messages by typing the dmesg
command at the HP-UX prompt.
Ensure that kernel contains driver by
issuing what command on kernel.

Troubleshooting 10/100Base-TX/9000
Troubleshooting Overview
Table 4-1
Troubleshooting Information
Symptom
Corrective Action
The card LEDs are okay, but you
can’t communicate with other
systems.
If the card LEDs appear to be okay:
1) Verify that the cable being used
complies with the IEEE 802.3u-1995
standard.
2) Ping the broadcast address for the
card, and check to see if the activity
light on the hub blinks. Other active
hosts must be connected to the hub or
else the activity light will not blink.
3) If the activity light on the hub does
not blink, and there are other active
hosts connected to the hub, open
another window and enter: netstat
-i 1
Try the broadcast ping again. The
transmitted packets counter should start
to increment. If the counter does not
increment, then there is an IP
configuration problem.
4) If the counter does increment, but the
activity light on the hub does not blink,
check the card’s activity light. If it is
blinking, the problem is likely with the
hub or connection to the hub. If the
activity light on the adapter is not
blinking, then there may be a problem
with the driver or the card. Contact HP.
Link LED off.

A.
Execute: ping to remote host.Using ping(1M), send
a message to the remote host to which you are having
problems connecting. For example:
ping spiff
B.
ping successful? A message is printed to stdout for
each ping packet returned by the remote host. If
packets are being returned, your system has network
level connectivity to the remote host. Note what
percentage of the total packets are lost, if any. Losing
ten percent or more may indicate the network or
remote host is extremely busy. You may also find it
useful to note the round-trip transmission times.
Periodically high transmission times may indicate that
the network or remote host is extremely busy.
Consistently high transmission times may indicate the
local host is extremely busy. If a message is not
returned after executing ping, ping is not successful.
Do Cntrl C to stop the ping output.
C.
Network unreachable? If yes, go to flowchart 3 to

D.
Loopback failed: Not an individual address. The
link level address is not correct. The first hexadecimal
digit has its high order bit set (if the value is equal to or
greater than 8, it is set). This means it is a multicast or
broadcast address, which is not allowed. The address
must be unique to one remote host. Go to F.

The official name for Fast
Ethernet.
100Base-TX: A specific
implementation of 100Base-T
designed to operate over Category
5 UTP cabling.
Alias: Name of the interface that
corresponds to a given Internet
address on a system. Refer to the
network map in appendix B for
example usage.
Autonegotiation: A mechanism
defined in IEEE 802.3u-1995
whereby devices sharing a link
segment can exchange data and
automatically configure
themselves to operate at the
highest capability mode shared
between them.The HP-PB
10/100Base-TX card supports
autonegotiation.
Autosensing: The ability of the
HP-PB 10/100Base-TX card to
detect a static speed of a hub or
switch and automatically configure
itself to operate accordingly. This
does not require the two-way
information exchange and
negotation process of full
autonegotiation.
CSMA/CD: Carrier sense multiple
access with collision detection. The
media access method implemented
in IEEE 802.3u-1995.
Card Instance Number: A
number that uniquely identifies a
device within a class. A class of

109
Full-Duplex Mode: A mode of
media utilization whereby data
can flow in both directions
simultaneously across the multiple
wire pairs of a physical link. While
full-duplex operation is not defined
per se in the IEEE 802.3u-1995
specification, the specification does
define a mechanism for this mode
to be autonegotiated between
devices on each end of a link.
Full-duplex mode is typically
found on switches. The HP-PB
10/100Base-TX card supports both
full- and half-duplex
communications.
Half-Duplex Mode: The media
utilization mode of IEEE
802.3u-1995 networks whereby
data can flow in only one direction
at a time across the multiple wire
pairs of a physical link.
Hardware Path: An identifier
assigned by the system according
to the physical location (slot) of the
card in the hardware backplane.
On Series 800 systems, the I/O
subsystem identifies each LAN
card by its hardware path.
Hostname: Name of system on
the network. Refer to the network
map in appendix B for example
usage.
110
Hub: A network interconnection
device that allows multiple devices
to share a single logical link
segment. Hubs are generally

CSMA/CD local area network,
which has been adopted by ANSI.
IEEE 802.3u-1995 network: A
10 or 100 megabit-per-second LAN,
specified in the IEEE 802.3u-1995
Standard for Local Area Networks.
It uses the Carrier Sense Multiple
Access/Collision Detection
(CSMA/CD) network access
method to give every node equal
access to the network.
Internet Address: The network
address of a computer node. This
address identifies both which
network the host is on and which
host it is. Refer to the Installing
and Administering LAN/9000

LAN/9000 Software manual for
detailed information about
subnetworks and subnet
addressing.
Subnet mask: A 32-bit mask
which, when AND'd with an
internet address, determines a
subnetwork address. When the
internet address is AND'd with the
subnet mask, the ones in the host
portion of the subnet mask will
“overwrite” the corresponding bits
of the host portion of the internet
address, resulting in the subnet
address. Refer to the Installing
and Administering LAN/9000
Software manual for detailed
information about subnet masks.
Switch: A network
interconnection device that allows
multiple connected senders and
receivers to communicate
simultaneously in contrast to a
hub (repeater) where only one
device can send at a time. Some
switches have fixed port speeds (10
