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.
Installing and Configuring 10/100Base-TX/9000 Required and Optional Patches Required and Optional Patches The following patches are required in order to use the HP-PB 10/100Base-TX/9000 card: Server • PHNE_17113—a patch for lanadmin changes on HP-UX 11.x versions. • PHNE_17000—a patch for lanadmin changes on HP-UX 10.20 versions. • PHCO_17631—a SAM patch for HP-UX 11.0-Based servers. • PHCO_17871—a SAM patch for HP-UX 10.20-Based servers. Workstation • PHNE_17113—a patch for lanadmin changes on HP-UX 11.
Installing and Configuring 10/100Base-TX/9000 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.
Installing and Configuring 10/100Base-TX/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.
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.
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.
Installing and Configuring 10/100Base-TX/9000 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.
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.

2 Configuring Network Connectivity Using SAM This chapter describes how to configure remote connectivity using SAM.
Configuring Network Connectivity Using SAM • Step 1: Configuring Network Connectivity • Step 2: Deleting a Default Gateway (Optional) 36 Chapter 2
Configuring Network Connectivity Using SAM Step 1: Configuring Network Connectivity Step 1: Configuring Network Connectivity Your system may not be able to communicate with other systems, for example, PCs, workstations, servers, etc., until you configure system-to-system connections by adding an entry in hosts for the remote system. You can use SAM to do this automatically by completing the following steps: 1. At the HP-UX prompt, type: sam 2.
Configuring Network Connectivity Using SAM Step 1: Configuring Network Connectivity Internet Addresses window. Proceed to step 5 if a gateway is not required for this remote connection. SAM displays fields for entering gateway information if a gateway is required for this remote system connection. Use the SAM online help system for information about gateways. 5. Activate the OK button to enable your system to communicate with this system and return to the System-to-System Connectivity object list.
Configuring Network Connectivity Using SAM Step 2: Deleting a Default Gateway Step 2: Deleting a Default Gateway To delete a default gateway that you have added with SAM, do the following: 1. Enter the following command at the HP-UX prompt: route delete default gateway_hostname where gateway_hostname is the hostname of the default gateway you want to delete. 2. Edit the /etc/rc.config.d/netconf file to remove the corresponding internet routing configuration parameter values for the gateway.

Troubleshooting 10/100Base-TX/9000 Diagnostic Flowcharts Flowchart Procedures A. Host entry in ARP cache? Using arp, check that an entry exists for the remote host in your system's ARP cache. For example: arp spiff B. Remote host up? If there is no ARP cache entry for the remote host, first check that the remote host is up. If not, the remote host has not broadcast an ARP message, and that probably is why there is no entry in the ARP cache. C. Bring-up remote host.

Troubleshooting 10/100Base-TX/9000 Diagnostic Flowcharts Flowchart 8: Procedures A. Execute: telnet to remote host. Try to establish a telnet connection to the remote host. B. Successful? If your telnet attempt was successful, stop. The connection is o.k. through the Transport Layer (OSI Layer 4). C. Execute: ftp to remote host. Unlike telnet, ftp does not go through a pseudoterminal driver (pty) on your system. This step tests to see if the pty is why telnet failed. D.

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.
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.
