Printing History New editions are complete revisions of the manual. Update packages, which are issued between editions, contain additional and replacement pages to be merged into the manual by the customer. The dates on the title page change only when a new edition or a new update is published. No information is incorporated into a reprinting unless it appears as a prior update; the edition does not change when an update is incorporated. Note that many product updates and ftxes do not require manual changes and, conversely, manual corrections may be done without accompanying product changes. Therefore, do not expect a one-to-one correspondence between product updates and manual updates. Edition 1 . .. February 1991 3 4 List of Effective Pages The List of Effective Pages gives the date of the current edition and of any pages changed in updates to that edition. Within the manual, any page changed since the last edition is indicated by printing the date the changes were made on the bottom of the page. Changes are marked with a vertical bar in the margin. If an update is incorporated when an edition is reprinted, these bars are removed but the dates remain. No information is incorporated into a reprinting unless it appears as a prior update. Pages Effective Date All .. February 1991 Preface This manual provides information for installing and administering the LAN/9000 product. The LAN/9000 product allows HP 9000 computers to connect to an IEEE 802.3 or Ethernet Local Area Network. The manual describes how to load, configure and initialize LAN software. It also describes how to maintain the network interface and how to use troubleshooting utilities. Finally, the manual provides a listing of diagnostic and event logging messages. The information in this manual is intended for network managers or operators who install and administer LAN/9000. It is assumed the reader is experienced with HP-UX and is familiar with the basics of local and wide area networking. The manual is organized as follows: Chapter 1 "Product Overview" describes product structure, relates software components to the Open Systems Interconnect (OSI) Reference Model and lists useful manuals. Chapter 2 "Networking Concepts" defines networking terms and explains network interface name and unit, network addresses, names and subnets, and LAN device concepts. Chapter 3 "Installing LAN" describes how to load and configure LAN/9000 software. It includes steps for configuring software automatically using the System Administration Manager (SAM). Chapter 4 "Maintaining LAN" explains how to administer LAN once the network is up. It also lists useful networking daemons and library routines. 7 Chapter 5 "Troubleshooting LAN" provides flowcharts for diagnosing common LAN/9000 problems. Chapter 6 "Using Network Diagnostics" explains useful diagnostic utilities. Chapter 7 "Using the Logging and Tracing Facility" describes the common logging and tracing tool, nettle Appendix A "Installation Error Messages" lists error messages related to loading and configuring LAN/9000 software. AppendixB "Diagnostics Error Messages" lists error messages returned by diagnostic utilities. Appendix C "Network Event Logging Messages" lists network event logging messages returned by LAN/9000. Appendix D "LANIC Statistics" describes LAN card status values and statistics returned by Zandiag(l M). Appendix E "LANIC Self-test Codes" lists error codes returned by a "failed" landiag(lM) interface test. Appendix F "LAN Filesets" describes the S800 include statements and S300 keywords required for generating a new kernel. 8 Contents Chapter 1 Product Overview Product Structure ............................... 1-2 Hardware Components .......................... 1-2 LAN Card ................................ 1-2 MAU ................................... 1-3 AUI .................................... 1-3 Stub Cable ................................ 1-4 Software Components ........................... 1-4 Programmatic Interfaces ........................ 1-4 Protocol Modules ............................ 1-4 Maintenance and Troubleshooting Tools .............. 1-5 Product Description . .. 1-6 Session Layer (OSI Layer 5) ....................... 1-7 NetlPC ......... ~ . .. 1-7 Berkeley Sockets ............................ 1-7 Transport Layer (OSI Layer 4) ...................... 1-7 TCP .................................... 1-8 PXP .................................... 1-8 UDP ................................... 1-8 Network Layer (OSI Layer 3) ...................... 1-9 Physical and Data Link Layers (OSI Layers 1-2) . .. 1-9 IEEE 802.3 Driver ........................... 1-9 Ethernet Driver ............................. 1-9 Link Level Access .. 1-10 Probe ................................... 1-10 ARP .................................... 1-10 Reference Manual Guide .......................... 1-11 Chapter 2 Networking Concepts Networking Terminology ... .. 2-2 Nodes .................................... 2-2 Routes and Protocols ........................... 2-2 Network Interface Name and Unit . .. 2-2 Gateway ................................... 2-3 Routing Table ............................... 2-3 Subnets ................................... 2-3 Network Addresses and Node Names ................... 2-5 Internet Addresses .............................. 2-9 Internet Address Formats ......................... 2-10 Assigning an Internet Address ...................... 2-12 Assigning Network Addresses .................... 2-12 Assigning Host Addresses ....................... 2-13 Subnet Addresses ............................... 2-14 Assigning Subnet Addresses ....................... 2-14 Assigning Subnet Masks .......................... 2-16 LAN Device Terminology .......................... 2-17 Hardware Path ............................... 2-17 Select Code ................................. 2-18 Device Logical Unit ............................ 2-18 LAN Device Files .............................. 2-19 Chapter 3 Installing LAN Overview of Installation ........................... 3-2 Creating a Network Map ........................... 3-3 Connecting LAN Hardware ......................... 3-6 Selecting LAN Filesets ............................ 3-8 Loading LAN Software on the Series 600/800 .............. 3-10 Adding LAN/9000 to a Series 600/800 HP-UX System ........ 3-10 Updating LAN/9000 Simultaneously with the Series 600/800 8.0 Operating System ............................. 3-12 Updating LAN/9000 After the Series 600/800 Operating System Has Been Advanced to 8.0 ....................... 3-13 Creating a New Kernel (Series 600/800) ................ 3-14 Installing for Real-Time Use ....................... 3-15 Editing the uxgen Input File for Real-Time Operation ...... 3-16 Loading LAN Software on the Series 300/400 .............. 3-17 Adding LAN/9000 to a Series 300/400 HP-UX System ........ 3-17 Updating LAN/9000 Simultaneously with the Series 300 8.0 Operating System ............................. 3-18 Updating LAN/9000 After the Series 300 Operating System Has Been Advanced to 8.0 ....................... 3-19 Creating a New Kernel (Series 300/400) ................ 3-20 Using Existing dfile ........................... 3-20 Using dfile.full.lan ............................ 3-22 Loading LAN Software on the Series 700 ................. 3-23 Verifying LAN Device File Creation .................... 3-24 Device Files on the Series 600/800 .................... 3-24 Device Files on the Series 300/400 .................... 3-25 Device Files on the Series 700 ...................... 3-26 Configuring LAN Software Using SAM .................. 3-27 Tips for Using SAM ............................ 3-28 Configuring LAN Cards ......................... 3-28 Configuring Network Connectivity .................... 3-29 Verifying Remote Systems ....................... 3-31 Undoing: Deleting a Default Gateway ............... 3-31 Configuring LAN Software Manually . 3-32 Creating the /etc/hosts Filty ........................ 3-32 /etc/hosts ................................. 3-33 /etc/hosts Format ............................ 3-33 /etc/hosts Permissions .......................... 3-34 /etc/hosts Example ........................... 3-34 Editing and Installing /etc/netlinkrc ................... 3-35 Editing /etc/netlinkrc .......................... 3-36 Installing /etc/netlinkrc ......................... 3-38 Activating Optional Network Features ................
