1 Introduction to Technology This chapter provides an overview of Ethernet technology and its features.
Introduction to Technology “Gigabit” Versus “Fast” Ethernet “Gigabit” Versus “Fast” Ethernet Throughout this document, the terms “Fast” and “Gigabit” Ethernet will be used. These terms refer to the following Ethernet technologies: • “Ethernet” refers to the original10Base-T Ethernet technology. • “Fast” Ethernet refers to the 100Base-T Ethernet technology. • “Gigabit” Ethernet is a generic reference to1000Base Ethernet.
Introduction to Technology Gigabit Ethernet Overview Gigabit Ethernet Overview Gigabit Ethernet is a high-performance, Ethernet networking solution for HP servers and workstations. The Local Area Network cards are data link cards 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.
Introduction to Technology Gigabit Ethernet Overview Set the ports on the card and on your switch according to the following table. The newest supported configuration is shown in the second row.
Introduction to Technology Gigabit Ethernet Overview • Jumbo Frames support: — Large 9000-byte maximum transmission unit (MTU) for improved efficiency and performance with bulk data transfer. On HP-UX 11i v2, the jumbo frames range is 1501 - 9000.
Introduction to Technology Gigabit Ethernet Overview Optional: If desired, you can also use the lanadmin -X command to temporarily set these values; but if you use the lanadmin command, your settings will not be saved across a reboot. The exact lanadmin commands are as follows (note that the -X is capitalized in these commands): lanadmin -X send_cko_on ppa lanadmin -X recv_cko_on ppa Please refer to the lanadmin man page for details of these CKO options.
Introduction to Technology Gigabit Ethernet Overview NOTE Currently only two values are allowed for the tunable “vmtu”: 0 and 32160. Setting “vmtu” to 0 (default) disables the TSO feature, and setting it to 32160 enables it. Changes to the Output of Current Commands If you are using NetTL or tcpdump to trace outbound packets may see differences from current behavior.
Introduction to Technology Gigabit card Overview Gigabit card Overview The Gigabit Ethernet intelligent cards are designed to maximize host CPU efficiency by performing functions such as TCP/IP checksum and interrupt coalescing. Bulk data transfers can be optimized by using Jumbo Frames; the large 9000-byte maximum transfer unit (MTU) improves system efficiency. The 1000Base-T cards are trispeed cards that support autonegotiation and autosensing.
Introduction to Technology Fast Ethernet Overview Fast Ethernet Overview Ethernet, or 10Base-T, is a standard for physically connecting computers into a local area network. It is a communications protocol that lets those computers share data. The most commonly installed Ethernet systems are 100Base-T and provide transmission speeds up to 100 Mbit/s. Fast Ethernet is a local area network (LAN) transmission standard that provides a data rate of 100 Mbit/s (referred to as “100Base-T”).
Introduction to Technology Fast Ethernet card Overview Fast Ethernet card Overview The Fast Ethernet La cards are data link cards that support the IEEE 802.3u-1995 standard for PCI-X 10/100Base-TX LAN operation over multiple-pairs of Cat-5 copper cables. For more detailed information on the Fast Ethernet cards and the platforms that support them, see the HP-UX Ethernet Driver Support Matrix, Edition 1 (for Releases up to March2004) on http://docs.hp.com under “Networking and Communications.
2 Installation and Configuration This chapter describes how to install your Ethernet card and configure the Ethernet parameters using the lanadmin(1M) command-line interface.
Installation and Configuration Installation Overview Installation Overview Installing Fast Ethernet or Gigabit Ethernet cards consists of the following steps: • Power down your system, or card section (if applicable) • Insert the card in the card cage • Power up your system, or card section (if applicable) • Install the appropriate driver(s) if necessary. • Configure the card • Verify the installation This chapter provides detailed instructions to install and configure your card.
Installation and Configuration HP-UX Ethernet Card, Driver, Version Matrix HP-UX Ethernet Card, Driver, Version Matrix The drivers for all of the HP-UX 11i-based networking and I/O cards can be found online in the HP-UX Ethernet Driver Support Matrix, Edition 2 (for Releases of Sept 2004 and Later). This matrix is a reference table, located in the Networking and Communications section of docs.hp.com.

Choose Exit from the File menu. 7. At the Networking Communications window, choose Exit SAM from the File menu to leave SAM. 8.
Installation and Configuration Manual Speed and Duplex Mode Configuration Manual Speed and Duplex Mode Configuration HP PCI-X Ethernet cards support both half- and full-duplex operation. Full-duplex mode is most commonly found in 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s switches. Full-duplex mode may provide a throughput advantage under some circumstances, but the degree of the advantage is application-dependent.
Installation and Configuration Manual Speed and Duplex Mode Configuration 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/hpbtlanconf 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 according to the Supported Configurations shown in chapter 1.
Installation and Configuration Removing a Card Removing a Card The exact steps involved in removing a card will vary depending on the type of system in which the card is installed. However, the process is not difficult and you should be able to successfully remove a card without receiving any error messages by using the following process: 1. Edit any of the following files that contain Ethernet card configuration entries: /etc/re.config.d/netconf /etc/rc.config.
Installation and Configuration Replacing a Card Replacing a Card The exact steps involved in replacing a card will vary depending on the type of system in which the card is installed. However, the process is not difficult and you should be able to successfully replace a card without receiving any error messages by using the following process: 1. Determine which slot has the card to be removed, and which slot is to receive the replacement card.
3 Administration This chapter provides information that will help with the administration of your Ethernet network.
Administration Gigabit-Specific Information Gigabit-Specific Information This section provides information that will help administer your Gigabit Ethernet products. Logging and Auditing Events are logged with NetTL. This is common to Gigabit Ethernet. The following log files are created by NetTL: • For releases prior to HP-UX 11i: nettl.LOG-00 and nettl.LOG-01 • For release HP-UX 11i and later: nettl.LOG000 and nettl.LOG001 See Chapter 4, “Troubleshooting,” on page 47 for more information about NetTL.

4 Troubleshooting This chapter provides flowcharts that will help diagnose Ethernet hardware and software problems.
Troubleshooting Troubleshooting Overview Troubleshooting Overview As with any troubleshooting process, a systematic approach is helpful. The following table and flowcharts provide a logical sequence of steps to follow when troubleshooting either Gigabit or Fast Ethernet. Using the diagnostic flowcharts: 1. Identify whether the problem is with Ethernet or any of the connections to the switch, or if the problem is in some other part of the network. 2. Verify your assumptions. 3.
Troubleshooting Diagnostic Flowcharts Diagnostic Flowcharts Table 4-1 summarizes the types of network tests in the diagnostic flowcharts. Table 4-1 Diagnostic Flowcharts Chart Chapter 4 Type of Test Purpose 1 Cable and LED Test Checks that hardware, cables and connectors between your system and card are operational. 2 Link Level Test Checks communication between link levels on source and target host using linkloop(1M).
Troubleshooting Diagnostic Flowcharts Flowchart 1: Cable and LED Test Use the process in this flowchart to ensure that the hardware, cables and connectors between your system and card are operational.
Troubleshooting Diagnostic Flowcharts • Check the dmesg/syslog output and look for error messages pertaining to gelan/igelan or btlan. Also, check the nettl log messages. If there are errors, check the card installation and reset or re seat the card. The following log files are created by NetTL: — For releases prior to HP-UX 11i: nettl.LOG-00 and nettl.LOG-01 — For release HP-UX 11i and later: nettl.LOG000 and nettl.LOG001 NOTE Chapter 4 • Verify the status of the card’s LEDs.
Troubleshooting Diagnostic Flowcharts Flowchart 2: Link Level Test Use the process in this flowchart to check communications between link levels on the source and target host by using linkloop(1M).
Troubleshooting Diagnostic Flowcharts Flowchart 2 Procedures The procedures in Flowchart 2 are: Chapter 4 • Enter linkloop(1M) to the remote host’s MAC address. If the linkloop result is successful, continue to the Network Level Tests (Flowchart 3). Otherwise, note which error was returned.
Troubleshooting Diagnostic Flowcharts Flowchart 3: Network Level Tests Use the process in Flowchart 3 to validate arp(1M) entries and remote host availability. This process also checks communication between network layers (see Figure 4-4 ) on source and target host using ping(1M) (see Figure 4-5).
Troubleshooting Diagnostic Flowcharts Flowchart 4: ARP Test Use the process in Flowchart 4 to validate arp(1M) entries and remote host availability.
Troubleshooting Diagnostic Flowcharts Flowchart 5: ping Test Use the process in Flowchart 5 to check communication between network layers on the source and target host by using ping(1M). Figure 4-5 Flowchart 5: ping Test ping Test Enter ping 2000 NO YES Enter netstat -in.
Troubleshooting Diagnostic Flowcharts Flowchart 5 Procedures The procedures in Flowchart 5 are: Chapter 4 • Enter ping(1M) to the remote host. If ping is successful, continue to the Transport Level Test (Flowchart 6). • If ping is not successful, enter netstat -in to verify MTU size. Ensure that the MTU size is the same on both the local and remote hosts (9000 for Jumbo Frames and 1500 for standard frames) by entering lanadmin -M new_mtu ppa, and repeat the ping Test.
Troubleshooting Diagnostic Flowcharts Flowchart 5 (continued) Figure 4-6 Flowchart 5: ping Test (continued) ping not successful YES Network unreachable? error? Configuration Tests NO YES No response from ping? YES NO Unknown host error? Do switches in the path support Jumbo Frames? Using jumbo frames (Gigabit only)?

Troubleshooting Diagnostic Flowcharts destination host. Otherwise, reconfigure the network path and repeat the ping Test. If you are not using Jumbo Frames, or the switches and path MTU are correctly set for Jumbo Frames (9000 bytes), go to the Cable and LED Test (Flowchart 1). Chapter 4 • If you receive an unknown host error, add the missing host name and repeat the ping Test.
Troubleshooting Diagnostic Flowcharts Flowchart 6: Transport Level Test Use the process in Figure 4-7 to check communications between transport layers on the source and target host by using telnet and ftp sessions.
Troubleshooting Diagnostic Flowcharts Chapter 4 • If the process is not successful, try to establish an ftp link 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/protocols file.
Troubleshooting Diagnostic Flowcharts Flowchart 7: Bridge/Gateway Loopback Test Use the process in Figure 4-8 to check the general network connections through a gateway.
Troubleshooting Diagnostic Flowcharts Chapter 4 • Enter ping(1M) from a known good host through a gateway to another known good host. This will test connectivity through the bridge/gateway level. If successful, run netstat -r and examine the route table on the problem host and all hosts in the path. If necessary, correct the routing table and go to Network Level Tests (Figure 4-3). • If ping fails, examine the gateway to see if it is an HP or non-HP product.
Troubleshooting Diagnostic Flowcharts Flowchart 8: Configuration Tests Use the process in Figure 4-9 to verify configuration of a network interface on a host by using ioscan(1M), lanscan(1M), netfmt(1M), lanadmin(1M) and ifconfig(1M).
Troubleshooting Diagnostic Flowcharts Flowchart 9: ioscan and lanscan Tests Use the process in Figure 4-10 (Flowchart 9) to verify the configuration of a network interface on a host using ioscan(1M) and lanscan(1M).
Troubleshooting Diagnostic Flowcharts Flowchart 9 Procedures The procedures in Figure 4-10 (Flowchart 9) are: • Enter ioscan(1M) as follows: ioscan -kfd drivername In this command, drivername is either btlan, gelan or igelan. Verify that the output from ioscan shows that the card is “CLAIMED” by the system. IMPORTANT Do not proceed to the next step until this step has been done! It is possible for a card’s bulkhead LED to indicate that the card is “present” when, in fact, ioscan will show that it is not.
Troubleshooting Diagnostic Flowcharts Flowchart 10: netfmt and lanadmin Tests Use the process in Figure 4-11 (Flowchart 10) to verify the configuration of the network interface on a host using netfmt(1M) and lanadmin(1M). Figure 4-11 Flowchart 10: netfmt and lanadmin Tests netfmt (logging) and lanadmin Test Enter netfmt.
Troubleshooting Diagnostic Flowcharts Flowchart 10 Procedures The procedures in Figure 4-11 (Flowchart 10) are: • Enter netfmt(1M) and view the error and disaster log messages. For example: netfmt -vf /var/adm/nettl.LOG00 It will help to use the time stamp to find proper logs. Ensure you are looking at Ethernet information. Note that the names of the NetTL log files are: — For releases prior to HP-UX 11i: nettl.LOG-00 and nettl.LOG-01 — For release HP-UX 11i and later: nettl.LOG000 and nettl.
Troubleshooting Diagnostic Flowcharts Flowchart 11: ifconfig Test Use the process in Figure 4-12 (Flowchart 11) to verify configuration of the network interface on a host using ifconfig(1M). Figure 4-12 Flowchart 11: ifconfig Test ifconfig Test Enter ifconfig netmask up. Enter ifconfig ifconfig successful ? NO Are flags correct? YES NO Correct ifconfig flag settings YES Call HP ifconfig entry in YES /etc/rc.config.
Troubleshooting Diagnostic Flowcharts ifconfig lan1 192.6.1.17 netmask 255.255.255.0 up Next, enter ifconfig interface to test and verify flag setting is UP and correct IP address is displayed. For example: ifconfig lan1 • If the IP and flags are correct, verify there is an entry for the card interface in /etc/rc.config.d/netconf. If so, go to Network Level Tests (Flowchart 3). Otherwise, add the correct interface parameters to /etc/rc.config.d/netconf file and reboot.
Troubleshooting Ethernet-Specific Information Ethernet-Specific Information This section provides references to information and useful tools for installing, configuring and maintaining Ethernet products. Error Messages Gigabit Ethernet comes with an online message catalog that is used to report networking problems. You must use the nettl logging and tracing utility to display the probable cause and action for a message.
Troubleshooting Ethernet-Specific Information • To examine just the log messages in the log file, enter: $ netfmt -f /var/adm/nettl.LOG000 • To check network logging and tracing status, enter: $ nettl -status • To start Ethernet tracing on the file /tmp/tracefile.TRC000, enter: nettl -traceon all -entity gelan -file /tmp/tracefile or $ nettl -traceon all -entity igelan -file /tmp/tracefile Note: nettl(1M) adds the .TRC000 postfix for you.

Cabling Requirements Gigabit Ethernet Gigabit Ethernet Connectors The connectors on La 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 SC or LC connectors. The 1000Base-T port is compatible with the IEEE 802.3ab standard and uses an RJ-45 connector. Cabling Incorrectly wired or installed cabling is the most common cause of communications problems for local area networks.
Cabling Requirements 10/100Base-TX Ethernet 10/100Base-TX Ethernet Connectors The connectors on La cards adhere to appropriate standards agreed upon by various standards bodies and are widely available. This section includes pin usage information for the RJ-45 twisted pair connector. PCI-X 10/100Base-TX card Twisted-Pair Connector The same connector on the card is used for either 10Base-T or 100Base-TX operation.
Cabling Requirements 10/100Base-TX Ethernet Connector Pin Usage for 100- Mbit/s Twisted-Pair Connector Use Category 5 unshielded twisted-pair cables that comply with the IEEE 802.3u 100Base-TX standard. Table B-3 shows the pins and signal TX end node. Table B-3 IEEE 802.
