Introduction
Product Overview
P r od u ct Over view
Gigabit Ethernet is a high-performance Ethernet networking solution for HP servers
and workstations.
The LAN adapters are data link adapters that support the IEEE 802.3z standard for
1000Base-SX operation over multimode fiber, and the IEEE 802.3ab standard for
1000Base-T operation over 4-pair Cat-5 or Cat-5E UTP copper wiring.
The Gigabit Ethernet intelligent adapters are designed to maximize host CPU efficiency
by performing functions such as TCP/IP checksum, interrupt coalescing, and byte
swapping. Bulk data transfers can be optimized with the use of Jumbo Frames; the large
9000 byte maximum transfer unit (MTU) improves system efficiency.
1000Base-T brings high bandwidth with 10, 100, and 1000 Mbps speeds, whch makes
more processing power available for applications. The tri-speed adapter supports
autonegotiation and autosensing. It operates in full-duplex mode at 10, 100, and 1000
Mbps or in half-duplex mode at 10 and 100 Mbps.
1000Base-SX supports full-duplex point-to-point or back-to-back (via switch to adapter
or adapter to adapter) operations only. The adapters do not support half-duplex and do
not speed negotiate (1000 Mbps operation only), but do perform autonegotiation for other
link parameters.
A6847A supports PCI only. Older 1000Base-SX adapters support HSC/PCI. 1000Base-T
supports PCI only.
The PCI adapters require a single slot in the host system and support all PCI bus
configurations: 32-bit, 33/66 MHz and 64-bit, 33/66 MHz. (Note: A6794A, A6847A, and
A6825A support 64-bit only.)

Configuring Gigabit Ethernet Parameters
Understanding the Gigabit Ethernet Parameters
Un d er sta n d in g th e Giga bit Eth er n et Pa r a m eter s
Several parameters can be configured using either the lanadmin(1M) command line
interface or the graphical user interface provided by the System Administration
parameters can be configured:
Gen er ic Pa r a m eter s

Eth er n et Sta tion Ad d r ess
The Gigabit Ethernet cards come preprogrammed with an Ethernet Station Address
in the read-only memory. This cannot be modified. However, the station address
actually used by the card for sending and receiving network packets, also known as
the MAC Address, can be set via lanadminor SAM.
Ma xim u m Tr a n sm ission Un it (MTU)
The MTU can be either the regular Ethernet MTU (1500 bytes) or the Jumbo Frame
MTU (9000 bytes). For 1000Base-T, jumbo frames can be configured only when the
link speed is 1000 Mbps.
Lin k Pa r a m eter s
•
Sp eed , Du p lexity, a n d Au ton egotia tion
While 1000Base-SX operates only at 1000 Mbps in full-duplex mode, 1000Base-T
operates at 10 or 100 Mbps in either half-duplex or full-duplex mode and also at 1000
Mbps in full-duplex mode.
The speed and duplexity of 1000Base-SX cannot be modified, but its ability to
autonegotiate can be turned on and off for other link parameters. Thus,
autonegotiation has no effect on the speed or duplexity of 1000Base-SX.
1000Base-T can be manually set to 10 or 100 Mbps but not 1000 Mbps. To achieve
gigabit speed, it must be allowed to autonegotiate with its link partner, and provided
the partner can autonegotiate, 1000Base-T will operate at the highest common speed
and duplexity. The following table summarizes the valid settings for 1000Base-T:

*When autonegotiation is on, 1000Base-T will autonegotiate with its link partner;
then, if its partner also autonegotiates and can attain a speed of 1000 Mbps,
1000Base-T will operate at 1000 Mpbs full-duplex (it is not designed to operate at
1000 Mbps half-duplex).
NOTE
Partners on a link must be configured to have the same setting, that is, either both
must autonegotiate or both must be set to the same manual setting. For example, if
the card is set to 100 Mbps full-duplex, the link partner must also be set to 100 Mbps
full-duplex. This will help ensure operation without degraded performance.
•
Receive flow con tr ol
Flow control allows use of flow control negotiation and sending and receiving of
pause frames. When the flow control parameter is on, the card receives and manages
pause frames sent by the link partner. When the flow control parameter is off, the
card will silently discard these pause frames. The card cannot be configured to send
pause frames.

CAUTION
These features are for advanced users. If you set these parameters and you do not
understand what they do, you may have unpredictable results. It is recommended to use
the default settings.
When the card transmits or receives a frame, the system must be notified of the event. If
the card interrupts the system for each transmitted and received frame, the result is a
high degree of processor overhead. To prevent that, Gigabit Ethernet provides a feature
called Interrupt Coalescence. Effective use of this feature can reduce system overhead
and improve performance.
Interrupt Coalescence essentially means that the card interrupts the system after
sending or receiving a few frames. The number of frames after which the card interrupts
the processor can be tuned independently for both send and receive. The tuning can be
specified via two parameters each for send and receive, so that there are four parameters

transmit (or receive) before interrupting and the other specifies the number of system
clock ticks that must elapse before interrupting.
The four tuning parameters are summarized in the following table.

Configuring Gigabit Ethernet Parameters
Using the lanadmin Tool with Gigabit Ethernet
Usin g th e la n a d m in Tool w ith Giga bit Eth er n et
This section explains the options available in lanadminto support the Gigabit Ethernet
driver and how to use them. The lanadmin(1M)tool is used to display and set
parameters, as specified by the following commands:
NOTE
When your system is rebooted, settings that were made via the lanadmin(1M)command
will be lost. To retain configuration settings permanently in the configuration file
(/etc/rc.config.d/hpgelanconfor /etc/rc.config.d/hpigelanconf), use the SAM
utility or manually edit the configuration file.
To display the card’s station address, execute:
$ lanadmin -a nmid/ppa
To set the card’s station address, execute:
$ lanadmin -A station_addr nmid/ppa
where nmid is the Network Management Identifier (NMID) (for HP-UX 10.20) and ppa
is the Card Instance Number (also known as physical point of attachment or PPA) (for
HP-UX 11.0 and later). Both the NMID and PPA may be obtained from the lanscan(1M)
output.
To display the MTU, execute:
$ lanadmin -m nmid/ppa
To set the MTU, execute:
$ lanadmin -M mtu_size nmid/ppa
On HP-UX 10.20, the setting of the MTU should be followed by configuring the interface
with the appropriate IP address using ifconfig(1M). See the ifconfigman page for
details. The change in MTU should be verified, on all HP-UX operating systems, by
executing:
$ netstat -rn
To display link parameters, execute:
$ lanadmin -x option nmid/ppa
To set link parameters, execute:
$ lanadmin -X option nmid/ppa
where optionspecifies the operation to be carried out.

A characterization of the problem. Describe the events leading up to and including
the problem. Attempt to describe the source and symptoms of the problem.
Your characterization should include: HP-UX commands; communication subsystem
commands; job streams; result codes and messages; and data that can reproduce the
problem. You should also provide a network map with the host name, IP/Internet
address, and station address of each system connected with the HP system.
Illustrate as clearly as possible the context of any message(s). Prepare copies of
information displayed at the system console and user terminal.
•
Obtain the version, update, and fix information for all software. For example, to
check the version number, execute:
what /stand/vmunix | grep gelanor the swlistcommand and look for
GigEther-00 (for gelan on HP-UX 11i and later)
or
what /stand/vmunix | grep igelanor the swlistcommand and look for
GigEther-01 (for igelan on HP-UX 11i and later).
To check the version of your kernel, execute uname -r.
This allows HP to determine if the problem is already known and if the correct
software is installed at your site.
•
Prepare copies of the /etc/hosts, /etc/rc.config.d/hpgelanconf(or
hpigelanconf), and /etc/rc.config.d/netconffiles.
•
•
•
Execute the dmesgcommand and record messages about the status of the card.
Execute the lanscan -vcommand and record the output.
Execute the displaycommand of the lanadmin diagnostic on the Gigabit Ethernet
interface and record the output.

•
Record the troubleshooting flowchart number where you are unable to resolve the
problem.
Record all error messages and numbers that appear at the user terminal and the
system console.
Save all network log files:
/var/adm/nettl.LOG00 and nettl. LOG01

Troubleshooting Overview
Tr ou blesh ootin g Over view
As with any troubleshooting, a systematic approach is helpful. The following table and
flowcharts provide a logical sequence of steps to follow when troubleshooting Gigabit
Ethernet. Using the diagnostic flowcharts, identify whether the problem is with Gigabit
Ethernet or any of the connections to the switch, or whether it is in some other part of
the network, verify your assumptions and, if it is limited to Gigabit Ethernet software or
hardware, correct the problem.
NOTE
To help ensure operation without degraded performance, make sure that both link
partners are set to autonegotiate, or, if using manual settings, that each side is set to the
same speed and duplexity.
If you cannot solve the problem on your own, call your HP representative. Use the
guidelines at the end of Chapter 3 to help you effectively communicate what is wrong.
The Gigabit Ethernet products use diagnostic tools compatible with the HP LAN Link
product.

Execute telnet(1M)to a remote host. If successful, stop.
If not successful, try to establish an ftp to a remote host. Unlike telnet, ftp does not
use a pseudoterminal (pty) driver on your system. This will determine if pty is why
telnet failed. If ftp is successful, call your HP representative to determine why you
have a problem with pty.
•
•
If ftp fails, check to see if TCP is configured on both hosts by verifying the
/etc/protocolsfile. Telnet and ftp work at transport layer and require TCP. If TCP
is not configured, configure now and repeat Transport Level Test.
If TCP is installed on both hosts, telnet to another host and/or use netstat(1M)to
check for lost packets. If network is congested, you may need to reconfigure network.
If network congestion is not the cause, more detailed network diagnostics are
required. In either case, call your HP representative.

Cabling Requirements
Ca blin g Requ ir em en ts
Connectors on LAN cards adhere to appropriate standards agreed upon by various
standards bodies and are widely available. The 1000Base-SX port is compatible with the
IEEE 802.3z standard and uses a single duplex SC connector. The 1000Base-T port is
compatible with the IEEE 802.3ab standard and uses an RJ -45 connector.
Incorrectly wired or installed cabling is the most common cause of communications
problems for local area networks. HP recommends that you work with a qualified cable
installer for assistance in your cabling requirements. The following tables summarize
cabling requirements:

the Installing and Administering LAN/ 9000
Software manual for detailed information about
network addressing.
Nod e: Any point in a network where services are
provided or communications channels are
interconnected. A node could be a workstation or a
server processor.
O
IP Ad d r ess: See Internet Address.
On lin e Ad d ition /Rep la cem en t (OLA/R): The
ability of a PCI I/O card to be added or replaced
without the need to shut down or reboot the system.
For instructions on how to perform OLA/R, refer to
Configuring HP-UX For Peripherals.
L
LAN: See Local Area Network.
Loca l Ar ea Netw or k (LAN): A data
communications system that allows a number of
independent devices to communicate with each
other.
P
P CI: Peripheral Component Interconnect.
Pa ck et: A sequence of binary digits that is
transmitted as a unit in a computer network. A
packet usually contains control information plus
data.
Loca l Netw or k : The network to which a node is
directly attached.
M
P h ysica l Poin t of Atta ch m en t: A unique number
assigned to each network interface, distinct from
NMID.
Ma jor Nu m ber : Unique value that identifies an
individual hardware device.
Ma xim u m Tr a n sm ission Un it (MTU): Largest
amount of data that can be transmitted through that
interface. This value does not include the LLC or
MAC headers.
P MTU: Path MTU
P PA: See Physical Point of Attachment
P r otocol: A specification for coding messages
Mbp s: Megabits per second
MBp s: Megabytes per second
MTU: See Maximum Transmission Unit

exchanged between two communications processes.
R
RJ -45: The name for the connector type used with
UTP cabling.
S
Netw or k In ter fa ce: A communication path
through which messages can be sent and received. A
hardware network interface has a hardware device
associated with it, such as a LAN or FDDI card. A
software network interface does not include a
hardware device, for example, the loopback
interface. For every IP address instance, there must
be one network interface configured.
Su bn etw or k : Small discrete physical networks
connected via gateways which share the same
network address space. Refer to Installing and
Administering LAN/ 9000 Software for detailed
information about subnetworks and subnet
addressing.
Su bn et m a sk : 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
Netw or k Ma n a gem en t Id en tifier (NMID): A
unique ID assigned by the system for the network
management of each network interface.
NMID: See Network Management Identifier

Administering LAN/ 9000 Software for detailed
information about subnet masks.
Sw itch : 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 or 100
Mbps) while others allow port speeds to be
configured or autonegotiated.
T
Top ology: The physical and logical geometry
governing placement of nodes in a computer
network. Also, the layout of the transmission
medium for a network.
U
Un sh ield ed Tw isted Pa ir : A data cable type
consisting of pairs of wires twisted together without
an electrically shielding jacket.
