Edition 1 September 1991 Edition 2 June 1992 Edition 3 September 1994 Edition 4 May 1996 Preface This manual describes the configuration, operation, and management of X.25 network connections for users of HP 3000 Series 900 systems with host-based network management. Host-based X.25 connections are available on systems running MPE XL release 3.1 or later MPE/iX release. You should use this manual only if the connections you are configuring are host-based X.25 connections. To configure X.25 connections for PC-based systems, refer to Configuring Systems for Terminals, Printers, and Other Serial Devices, Using the OpenView DTC Manager, and the HP 3000/iX Network Planning and Configuration Guide instead of this manual. You should be familiar with X.25 concepts and know which X.25 facilities are included in your network subscription. You should also be familiar with NMMGR, the tool used to configure network connections. If not, refer to Using the Node Management Services (NMS) Utilities manual (32022-90041) for information. This manual includes step-by-step instructions to assist you in configuring all aspects of host-based X.25 connections for a system. It includes a description of DTCCNTRL, the command used to start, stop, dynamically reconfigure, and obtain status about host-based X.25 system-to-system and PAD connections. It also includes an explanation of and instructions for using the X.25 log formatting tool, EVLOG. Note MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories). MPE V is the old operating system for HP 3000s, not based on the PA-RISC architecture. MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as compatibility mode. The chapters in this manual are organized as follows: * Chapter 1, Introduction, presents an overview of the host-based X.25 capabilities that are provided as part of the Fundamental Operating System (FOS). It describes network options, concepts, and diagnostic services for use with host-based X.25 links. * Chapter 2, Preparing to Configure DTCs, details the information you will need before you can begin to configure DTS for systems with host-based X.25 connections. It also describes worksheets you can use to plan and record your DTS configuration. * Chapter 3, Configuring DTCs Step-by-Step, provides step-by-step instructions for configuring DTCs for systems with host-based X.25 connections. * Chapter 4, Terminal and Printer Profiles, describes what are terminal and printer profiles and how to create and modify your own profiles. * Chapter 5, Preparing to Configure X.25 iX System Access, details the information you will need before you can begin to configure X.25 iX System Access for systems with host-based X.25 connections. It also describes worksheets you can use to plan and record your NS configuration. * Chapter 6, Configuring X.25 Links Step-by-Step, provides step-by-step instructions for configuring X.25 iX System Access for systems with host-based X.25 connections. * Chapter 7, Managing Networks with DTCCNTRL, describes how the DTCCNTRL command is used to start, stop, dynamically reconfigure, and obtain status about host-based X.25 system-to-system and PAD connections. Examples of command usage are included. * Chapter 8, Formatting Host-Based X.25 Log Files, provides instructions for using EVLOG, the log formatter for X.25 log events. It includes a description of each of the EVLOG options. * Appendix A, Error Messages, contains validation, datacommunication configurator (DCC), and DTCCNTRL error messages. * Glossary contains terms applicable to the network configuration process.

These tasks are not covered in this manual: 1. Set up your HP 3000 and make sure it is operational. Refer to your HP 3000 installation manual. 2. Install the DTC terminal servers on your LAN and connect the serial devices to the DTC terminal servers. Refer to your DTC hardware installation guide. Configuration Overview Using New Configuration File The following steps summarize the procedure for configuring your HP 3000 systems to use DTC terminal servers if you are using a new network configuration file. For detailed information on these steps, refer to chapter 3. 1. Copy the sample configuration file to NMCONFIG.PUB.SYS. 2. Run NMMGR.PUB.SYS. 3. Enter your HP 3000 node name, link name, and LANIC slot number. 4. Define each DTC to be connected with the HP 3000. 5. Configure each board in the DTC. 6. Validate your network configuration. (SYSGEN cross-validation is done automatically within NMMGR.) 7. Exit NMMGR. 8. Use DTCCNTRL to shutdown and restart DTS. Reset the DTC terminal servers. Dynamic Configuration You can also make many DTS changes dynamically without rebooting the system or performing a DTS shutdown/restart if you already have a valid network configuration file and there were no DCC errors reported during the last system reboot. The steps below summarize the procedure for dynamically configuring DTS. Refer to chapter 7for more information on dynamic configuration. For detailed information on the steps below, see chapter 3. 1. Run NMMGR.PUB.SYS. 2. Modify your existing DTS configuration as necessary. 3. Validate your network configuration. (SYSGEN cross-validation is done automatically within NMMGR.) 4. At the prompt seen after cross-validation is complete, select to have DTS changes take effect dynamically. 5. Exit NMMGR. 6. Complete any additional actions as appropriate (such as resetting the DTC) for changes to become active. Automatic Configuration If you are using host-based management to manage your DTCs, you can also add and configure a new DTC automatically without needing to specify detailed configuration information such as DTC cards/boards and ldevs. This can be done either within the NMMGR utility or without running NMMGR. Refer to chapter 7.
NOTE If you are using the HP OpenView DTC Manager on the PC to manage the DTCs, you must also configure the OpenView DTC Manager. For more information, refer to Using HP OpenView DTC Manager (D2355-90001).
