Configuring and Managing Host-Based X.25 Links - Edition 5 (36939-90054)

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 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.
