Product description

The IBM® Netfinity® Gigabit Ethernet Adapter connects your PCI-compliant server or workstation to a Gigabit Ethernet network. The adapt er incorporates a technology that

transfers data at a maximum rate of one gigabit per second—10 times th e r a te of a Fast Ethernet adapter.

The Netfinity Gigabit Ethernet Adapte r tar gets the increase d congestion experienced at the backbone and ser ver in today’s networks, while providing a future upgr a de path for highend workstations that require more bandwidth than Fast Ethernet can provide.

The following items are i ncl uded in your option package:

• Netfinity Gigabit Ethernet Adapter CD with device driver software and documentation.

• The IBM Netfinity Gig abit Ethe rnet Adapter in a n anti-sta tic ba g (use d for prote cting the adapter when stored or shipped). Keep the adapter in the packaging until you are ready to install it.

If any of these items are missing or damaged, contact your resel ler. Keep your original packing material; it might be required if you need to return your adapter.

The Netfinity Gigabit Ethernet Adapter supports the following features:

• Full-duplex Gigabit Ethernet interface (IEEE 802.3-1999)

• Jumbo Frame su pport (optional 9,000 byte frames for server-to-server traffi c)

• VLANs: up to 64 VLANs per adapter using IEEE 802.1Q-1998 tagg ing

• Compatibility with existing Ethernet and Fast Ethernet equipment

• Standard Ethernet frame size (up to 1,518 by te s)

• Supports 32 multicast addresses

• Adapter failover to an Intel

82559 LAN on Motherboard (LOM)

• Adaptive interrupt frequency (maximizes network throughput; adapts to traffic load)

• Dual DMA channels

• 33/66 MHz, 32-bit or 64-bit PCI bus master with adaptive DMA

• PCI Local Bus Rev 2.2 compliant: 17.3 cm x 10.7 cm (6.8 in. x 4.2 in.)

• ASIC with on-chip MAC and dual RISC processors

Key protocols and interfaces

The Netfinity Gigabit Et herne t Ada pt er is compati ble with ex istin g Eth erne t equip men t assuming standard Ethernet minimum and maximum frame size (64 to 1518 bytes), frame format, and compliance with the following standards and protocols:

• Gigabit Ethernet (IEEE 802.3-1999)

• Logical Link Control (IEEE 802.2)

• Flow Control (IEEE 802.3x)

Jumbo Frames support

When sending Ethernet traffic at Gigabit speeds, considerable bandwidth is consumed by the overhea d of hand ling a mu ltitude o f standard 1,500 b yte pac kets. The Ne tfinity Gig abit Ethernet Adapter and Alteon WebSystems switches suppo rt Etherne t frames of up to 9,000 bytes. Host CPU utilization is significantly reduced and network throughput is enhanced when enabling Jum bo Frames between servers that have IBM PCI adapters.

For user datagram proto col (UDP) tra f fic, an IBM Netfinity Gigabit Ethern et Adapter c an support standard Ethernet frames and Jumbo Frames at the same time. When attached to an Alteon WebSystems switch, Jumbo Frames are sent only between servers that have Netfinity Gigabit Ethernet Adapters. When attached to a standard Ethernet device, a Jumbo Frames-enabled server might send UDP data in Jumbo Frames, but when the data reaches the switch, the switch automatically fragments the data into standard Ethernet frames when sending to all other standard Ethernet devices.

For non-UDP traffic, both servers must support Jumbo Frames.

VLANs support

Virtual local area networks (VLANs) are commonly used to divide groups of network users into manageable broadcast domains, to create log ical segmentation of workgroups, and to enforce security policies among logical segments.

Each Netfinity Gigabit Ethernet Adapter supports up to 64 VLANs, depending on the amount of memory available in your computer. With multiple VLANs on an adapter, a server with a single adapter can have a lo gical pr esence on mu ltiple IP subnets. For d etails about planning networks with VLANs, refer to your Alteon WebSystems switch software manual.

Adapter teaming

Teaming provides re dundant adapter operation in the event that a network connection fails. When multiple Netfinity Gigabit Ethernet Adapters are installed in the same server, they can be paired into teams. Up to two teams, each with two adapte rs, can be configure d on the server.

If traffic is not detected on the pri mary adapter connection in a team because the adapter, cable, switch port, or switch (where the teamed adapters are attached to separate switches) fails, the secondary team member becomes active, taking t he MAC and IP address originally assigned to the primary adapter. Sessions are usually maintained, causing no impact to the user.

1-2 Netfinity® Gigabit Ethernet Adapter User’s guide

Adaptive interrupt frequency

The adapter device driver automatically adjusts host interrupt frequency based on traffic conditions to increase overall application throughput. In light traffic, the adapter device driver interrupts the h ost for each received packet, minimizi ng latency. When traffic is heavy, the adapter issues one host interrupt for multiple, back-to-back incoming packets, preserving host CPU cycles.

Dual DMA channels

The PCI interface on the Netfinity Gigabit Ethernet Adapter contains two independent direct memory access (DMA) channels for simultaneous read and write operations.

32-bit or 64-bit PCI bus master

Compliant with PCI Local Bus Rev 2.2, the PCI interface on the Netfinity Gigabit Ethernet Adapter is compatible with b oth 32-bit and 64 -bit PCI buses. As a bus master , the adapter requests access to the PCI bus instead of waiting to be polled.

ASIC with embedded RISC processor

The core control for the Netfinity Gigabit Ethernet Adapter resides in a tightly integrated, high-performance ASIC. The ASIC includes dual RISC processors. This provides the flexibility to add new featu res to the adapter a nd upgrade it to fu ture network requirements through software do wnload. This also enab les the a dapter d evice d rivers to use the built-in host off-load functions on the adapter as host operating systems are enhanced to take advantage of these fu nctions.

Connectors

The faceplate on the Netfinity Gigab it Apater prov ides an RJ-45 conn ec tor for connec ting the adapter to another network device.

LEDs

The faceplate of the Netfinity Gigabit Ethernet Adapter has four LEDs: one for each port speed option (10Mbps, 100Mbps, and 1Gbps), to indicate which link is active, and one LED for data transfer status. Until the driver software is properly installed, all four LEDs remain lit when the server is turned on.

When the adapter hardware and device driver software have been properly instal l ed on your computer, the LEDs indicate the adapter states, according to the followi ng table.

LED State Description

Data Blinking Brief bursts of data are detected on the port.

Data On Streams of data are detected on the port.

Data Off No data is detected on the port.

1000 On Good 1000 Mbps (G iga bit) Ethernet link.

User’s guide 1-3

LED State Description

1000 Off No 1000 Mbps link: possi ble link at different speed,

possible bad cabl e, ba d connector, or configuration mismatch.

100 On Good 100 Mbps Etherne t link.

100 Off No 100 Mbps link: po ssi bl e li nk at different speed,

possible bad cabl e, ba d connector, or configuration mismatch.

10 On Good 10 Mbps Ether ne t li nk.

10 Off No 10 Mbps link: possible li nk a t di fferent speed, possible

bad cable, bad con nector, or configuration mismatc h.

If all four LEDs remain lit simultaneously, the adapter driver software is either missing or improperly installed.

1-8 Netfinity® Gigabit Ethernet Adapter User’s guide

• Link negotiation

— When checked (default), 802.3-1999 complia nt Gigabit Ethernet link

negotiation is enabled. All Netfinity Gigabit Ethernet Adapters use link negotiation by default.

— When unchecked, link negotiation is disabled an d only link signal

detection is used. Use this setting when connecting to Ethernet equipment that does not support lin k negotia tion, or if there is a problem e stablishing a link between the adapter and the connecting device. Unless otherwise specified, the default signaling speed is 1Gbps.

When link negotiation is disabled, be sure that the connecting device uses the same duplex and speed settings.

Note: When link negotiation is on, the user-configured link speed and

duplex settings are ignored in favor of automatically determined settings.

• Full Duplex Enabled

When link negotiation is unchecked, this parameter sets the duplex mode. You can select e ither half-duplex or full-duplex operation.

— When checked, full-duplex signaling is used (default). — When unchecked, half-duplex operation is used.

• Tx Flow Control

—When Tx flow control is checked and lin k negotiation is enabled, the

adapter will negotiate 802.3x transmit flow control with the device at the other end of t he link. If 802.3x flow control is supported by the othe r device, Tx flow control will be enabled.

—When Tx flow control is checked and link nego tia tio n is disab le d, you

must check Full Duplex Enabled in order for Tx flow control to work properly. Tx flow control will not function under half duplex operati on.

—When Tx flow control is unchecked (default), or when Full Dupl ex

Enabled is unchecked, transmit flow control is disabled.

• Rx Flow Control

—When Rx flo w contr ol is c hecked (d efault) and lin k neg otiation is ena bled,

the adapter will negotiate 802.3x re ceive flow contro l with the dev ice at the other end of t he link. If 802.3x flow control is supported by the othe r device, Rx flow control will be enabled.

—When Rx flow control is checked and link negotiation is disabled, you

must check Full Duplex Enabled in order for Rx flow control to work properly. Rx flow control will not function unde r half duplex operation.

— When unchecked, or when Full Duplex Enabled is unchecked, receive

flow control is dis ab le d.

User’s guide 1-9

• Jumbo Frames

— When checked, Jumbo Frames (up to 9,000 bytes) is supported by the

adapter. This setting can reduce ho st CPU ove rhe ad and inc re a se bandwidth when sending to other devices that support Jumbo Frames. When attached to an Alteon WebSystems switch, Jumbo Frames will be sent only between end-stations tha t ha ve Netfin ity Giga bit Ether net Adapters. When sending to standard Ethernet devices, the switch automatically fragments the Jumbo Frames traffic into standard Ethernet frames.

— When unchecked (default), only standard-sized Ethernet frames will be

sent. Use this setting when connecting to Gigabit Ethernet equipment that does not support Jumbo Frames.

• Port Link Speed When link negotiation is disabled, this parameter sets the port link speed. You

can select link speed to be either 10Mbps, 100Mbps, or 1Gbps. When the port link is connected, the selected link speed is indicated to the right of this field.

• VLAN Count This field reflects the number of VLANs configured for the selected adapter.

When there are no VLANs configured for the selected adapter, VLAN support is disabled. This is an inform a tion f iel d and cannot be configur e d direc tly thro ug h this tab.

Note: Netfinity Gigabit Ethernet Adapt ers that are member s of a Failover Team

can be configured to support VLANs. However, VLANs cannot be configured for a stand-alone Intel LAN on motherboard (LOM) or a Failover Team that includes a LOM.

• Number of NICs in a Team When a Failover Team is selected in the Adapter list, this field represents the

total number of adapters configured for the selected team. This field does not apply when an individua l (n on-t eamed) adapter is selected in the Adapter list. This is an information field and cannot be configured directly through this tab.

Failover Teaming

This section provides instructio ns for configurin g the option al Failover Teaming feature of your Netfinity Gigabit Ethernet Adapter.

Failover Teaming provides redundant adapte r operation in the event that a network connection fails. When multiple adapters are installed in the same computer, they can be paired into teams. Up to two teams, each with two adapters, can be configured.

If traffic is not detected over the primary adapter connection in a team because the adapter, cable, switch port, or switch (where the teamed adapters are attached to separate switches) fails, the secondary team member becomes active, taking t he MAC and IP address originally assigned to the primary adapter. Sessions are maintained, causing no impact to the user .

Failover Teaming configura t ion

Configuring Failover Teaming consists of the following:

• Accessing the failover configuration interface

• Creating teams

• Adding adapters to the teams

• Assigning IP addresses to the teams

• Restarting your computer

Accessing the failover configuration interface

To access the adapter properties for Failover Te am Configuration, do the following:

1. Click Start → Settings → Control Panel.

2. Click Network.

3. Click the Adapters tab.

4. Select any Netfinity Gigabit Ethernet Adapter or Team entry; then click Properties.

User’s guide 1-15

Creatin g a t ea m an d as s igning adapters

A Failover Team consists of two adapters: a primary adapter and a backup adapter. Each adapter can belong to only one team.

To configure a new Failover Team, d o t he fol lowing:

1. Open the Netfinity Gigabit Ethernet Adapter Device Drivers window.

2. Click the Failover Team Configuration tab.

3. In the NICs Available list, select the adapter that you want to be the primary adapter for the team.

The adapter is highlighted when your selection is made. Th e selected basic configuration of the adapter (Link Negotiation, Jumbo Frame, and Flow Control settings) are used as the starting point for the new team configuration.

Note: Release 2.3 supports grouping Netfinity Gigabit Ethernet Adapters with an

82559 Intel LAN on motherboard (LOM) into Failover Teams. However, this release does not support assigning a LOM as a primary adapter (the adapter for which you want to provide failover).

4. Click Create a Team. A new team instance will be created in th e team list. The selected adapter is

automatically moved from the NICs Available list to the Team list under the newly created team. You can create up to two teams.

Note: The newly crea ted Failove r Team inherits all the ba sic configura tion prop erties

(Jumbo Frame support, Flow Control setting, Link Negotiation, Port Speed, and VLANs, when assigned) from the primary adapter. Other adapters added to the team are automatically reconfigured to match the team configuration. When a team basic configuration properties are changed using the NIC Status and Configuration tab (see step 11 on page 1-8), this changes the configuration of all adapters in the team. However, when an adapter is removed from any Failo ver Teams, it operates according to the parameters set for it before it became a memb er of a Failover Team.

5. Pl ace another adapter into the team. Each team must consist of two adapters. To add an adapter to a specific team, be sure

that the team is highlighted in the Team list. If the desired team is not highlighted, select the team instance in the Team list.

VLANs

Your Netfinity Gigabit Ethernet Adapter can be configured to support virtual local area networks (VLANs). This section provides instructions for configuring optional VLANs for an adapter.

If you do not want to configure your network to include multiple VLANs, you need only to configure the a dapter to supp ort the de fault conf iguration , as describe d in “Install ing the

device drivers” on page 1-6. Note: Adapters that are members of a Failov er Team can also be configured to support

VLANs. When configuring VLANs for Failover Team adapters, any adapter or LAN on motherboard (LOM) that is a member of a team inherits the configuration of the primary adapter. However, when an adapter or LOM is removed from the team, its original configuration parameters are used.

With VLANs, you can divide your physical LAN into logical subparts to create logical segmentation of workgroups and to enforce security policies among each logical segment. Each defined VLAN behaves as a separate network, with traffic and broadcasts isolated from the other s , increasing band width efficiency within each logical group. Up to 64 VLANs can be defined for each adapter on your computer, depending on the amount of memory your computer has available.

User’s guide 1-19

Although VLANs are commonly used to crea te individual broadcast domains or separate IP subnets, it is sometimes useful for a server to have a presence on more than one VLAN simultaneously . Alteon WebSystems switches and Netfin ity Gigabit E thernet Adapt ers use VLAN tagging to support multiple VLANs on a per-port or per-interface basis, allowing very flexible network configurations. VLAN tagging is a format used to identify packets according to membe r ship in a particular VLAN.

VLAN tagging is only required to be enabled on switch ports that create trunk links to other Alteon WebSystems switches, or on ports connected to tag-capable end-stations, such as servers or workstations with Netfinity Gigabit Ethernet Adapters.

Configuring VLANs

By default, Netfinity Gigabit Ethernet Adapters are configured with VLAN support disabled. Up to 64 VLANs can be defined for each adapter on your se rver, depending on the amount of memory it has available .

To configure VLANs, you must take the following steps:

• Access the VLAN configuration interface

• Add VLANs to the adapters. This includes assigning a unique identifier and, optionally, a name to each new VLAN .

• Restart the computer Note: VLANs are not supported on non-Netfinity Gigabit Ethernet Adapters,

including an Intel stand a lon e LA N on m othe rbo a rd (LOM ). If a no n -Netfi nit y Gigabit Ethernet Adapter is a member of a Failover T eam, VLANs will not be supported for that team.

Accessing the VLAN configuration interface

To access the adapter properties for VLAN configuration, do the following:

1. Click Start → Settings → Control Panel.

2. Double-click Network.

3. Click the Adapters tab.

The bus and slot number of the highlighted adapter is listed in the lower part of the window.

4. Select any Netfinity PCI Gigabit Ethernet Adapter and click Properties.

1. In the NICs Available list, select the first adapter that you want to add a VLAN to.

2. The adapter is highlighted when your selection is made.

3. Click the Add VLAN.

4. In the VLAN Properties window, enter a unique number. You must assi gn a unique identification number to each VLAN you create. Even

though the maximum number of VLANs that can be configured on each adapter is 64, any particular VLAN can be assi gned an identification numb er between 1 and

4094. The VLAN tagging format follows the guidance provided in IEEE 802.1Q-1999. Be

sure that there are no spaces, blank l ines, or extra characters. The identifier can be entered in decimal (for example, 383), octal (for example, 0577), or hexadecimal (e.g. 0x17F) format.

Note: When assigning a number for a VLAN, do not use the de fault VLAN identifie r

used by the adapter or th e switch. Match the VLAN configuration with the configuration on the switch or server; that is, if you have already identified VLANs 383 and 777 on the switch or server, the VLAN IDs for the new adapters must match.

5. (Optional) In the VLAN Properties window, ty pe a name for the VLAN you are creating.

6. If Jumbo Frames will be sent to or received by the adapter VLAN, click the check box next to Jumbo Frames.

To perform the internal loopback diagnostic test on an adapter, do the following.

1. Click Start → Settings → Control Panel.

2. Double-click Network.

1-24 Netfinity® Gigabit Ethernet Adapter User’s guide

3. Click the Adapters tab.

4. Select any Netfinity Gigabit Ethernet Adapter and click Properties.

The Netfinity Gigabit Ethernet Adapter Device Driver properties window opens.

5. If you want to run internal loopback diagnostics on an adapter, select the NIC Status and Configuration tab; then select the adapter that will be tested.

6. Click the Tech Support tab. This window provides contact information and access to the internal diagnostic test.

7. To view the Diagnostics widow, click Diagnostics.

8. When the Diagnostics window opens, click Test to run the internal loopback test for the adapter.

During this test, packet data is sent across the media access control (MAC) chip to verify that traffic can be sent and received through the adapter. During the test, the Diagnostics window displays the following messages, indicating that the test is in progress and the results of the test:

• Diagnostic firmware loaded OK (when running the test for the first time)

• Running diagnostic test

• Test completed OK

• Normal adapter firmware loaded OK

When the test is completed, the result (Passed or Failed) is displayed in the Internal Loopback Test field.

ALTDIAG internal/external loopback test (MS-DOS)

ALTDIAG, a Microsoft MS-DOS® diagnostic utility, is included on the Netfinity Gigabit Ethernet Adapter CD. This utility is used for verifying that the adapter hardware is

functional. It performs intern al and external loop back tests and provides resulting pass or fail information. Perform the ALTDIAG tests any time you want to rule out or identify possible adapter hardware problems.

To use the ALTDIAG utility, do the following:

1. Start your computer in MS-DOS mode instea d of in Windows NT mode. Note: ALTD IAG cannot be used from the Windows NT Start menu. To use

ALT D I AG, you must start your co mputer in MS-DOS mode, with no other plug-ins , add-ons, or resident programs installed.

2. Disconnect the netw ork cables on all adapt ers being tested. The loopback tests will not perform properly if the adapter is connected to other

devices.

3. Connect a Cat. 5 UTP loopback cable to the adapter’s RJ-45 jack.

A loopback cable can be constr uc te d by conne cting the following pins back to the single connect or:

• Pin 1 to Pin 3

• Pin 2 to Pin 6

• Pin 4 to Pin 7

• Pin 5 to Pin 8

User’s guide 1-25

4. Place Netfinity Gigabit Ethernet Adapter CD into the CD-ROM drive of your computer.

5. From the MS-DOS prompt, type the following commands to access the proper directory (where X is the drive letter of your CD-ROM drive):

cd \dosdiags

Note: If you acquired the diagnostic software on a diskette or from the IBM support

Web site, specify the path to where the files are saved on your computer.

6. From the MS-DOS prompt, type the following command to run diagnostics:

dos4gw altdiag [-c card_number] [-l c:log_filename]

If more than one adapter is installed in your computer, the optional -c parameter can be used for specifying the adapter ca rd to b e tested. Car ds are number ed starting with

0. By default, ALTDIAG tests only the first card (number 0) detected in the computer.

The optional -l (letter L for “log”) parameter is used for defining a file in which to log the test results. A text copy of the ALTDIAG test results is placed in the specified file on the specified drive.

Example: T o te st the second card in a system and sto re the test results in log.txt in the current directory on the C: drive, the following command could be used:

dos4gw altdiag -c 1 -l c:log.txt

7. Review the test results. The test result from the previous example might look like this:

If the adapter does not perform as expected, try reinstalling the adapter or moving it to a different slot or to a different computer; then run the ALTDIAG tests again. If the adapt er still fails, contact the IBM HelpCenter.

Checking the port LEDs

The faceplate of the Netfinity Gigabit Ethernet Adapter has four LEDs: one for each port speed option (10Mbps, 100Mbps, and 1Gbps), to indicate which link is active; and one LED for data transfer status.

Before the port LEDs can provide troubleshooting information, the adapter must be connected to the network (see “ In sta llin g th e Net finity Gigabit Ether ne t Ad apte r” on pa g e

1-5), and th e n etwo rk de vic e driv ers for your pa rticul ar oper ati ng sys tem must be in sta lled (see “Installing the device drivers” on page 1-6).

1. Verify that the adapter device driver software has been installed and that the adapter is connected to a network.

2. Verify that the adapter status LEDs operate as described in the following table.

LED State Descri pti on

Data Bl inking Brief bursts of data are detecte d on the port.

10 Off No 10 Mbps link: possible link at different speed, possible

bad cable, bad connector, or configuration mismatch.

Note: If all four LEDs remain lit simultaneously, the adapter device driver software

is either missing or improperly installed.

Troubleshooting checklist

The following checklist provides recommended actions to take to resolve problems installing the Netfinity Gigabit Ethernet Adapter or running it in your computer.

• Inspect all cabl es and connections. Verify th at the cable connections at the adap ter and the switch are attach ed properly. Be sure that the cable lengt h and rating comply with the requirements listed in “Connecting the network cables” on page 1-6.

• Connect the adapt er to a different network port and run the tests agai n. If the test results reflect that the adapter is fun ctioning prop erly, the original network port might be defective or improperly c onfigured.

• Check the adapter installat ion by reviewin g “Installing the Netfinit y Gigabit Etherne t Adapter” on page 1-5. Be sure that the adapter board is properly seated in a PCI slot. Check for spe cif ic har dw are p ro blems , su ch a s ob viou s da ma ge to boa rd co m ponen ts or the PCI edge connector.

• Check the configuration settings and change them if they conflict with another device.

• Be sure that your computer is using the latest BIOS.

• Try in serting th e adap ter in a nothe r slot. If if it works in the n ew positi on, t he orig inal slot in your computer might be defective.

• Replace the failed adapter with one that is known to work prop erly. If the second adapter works in the slot where the first one failed, the original adapter is probably defective.

• Install the adapter in another functioning computer and run the tests again. If the adapter passed the tests i n t he new computer, the original computer might be defective.

• Remove all other adapters from the computer and run the test s again. If the adapter passes the tests, the other adapters might be causing the problem.
