The X.25 link implements the CCITT X.25 Recommendations and contains the components necessary to connect an HP 9000 to a public or private packet switching network conforming to the CCITT X.25 Recommendation (1980, 1984 or 1988), or to another system in a back-to-back configuration.

The information in this manual applies to HP 9000 Series 700 and 800 systems that use single, dual, or quad-port communications hardware. Any differences are specifically noted.

NOTE In a diskless cluster, X.25 software is only supported on the server

system. It is not supported on client systems for this type of environment.

The following diagram illustrates the X.25 link architecture where:

• solid white boxes represent the product’s integral components.

• lightly shaded boxes represent the product’s protocol components.

• heavily shaded boxes represent optional components (external to the product) that can be added to the product.

Each component depends on the component(s) below it and must be installed and running in order to support higher-level components.

Application (L7), Presentat ion (L 6), and Session (L5) Levels

Application (L7), Presentation (L6), and Session (L5) Levels

The X.25 link does not provide any components for the general support of the application and presentation levels (levels 7 and 6, respectively), although X.25/9000 PAD Services do provide some of the functionality of these levels.

User-written application programs, Internet Services/Berkeley Services (via BSD Sockets) and NS (via NetIPC Sockets), are accessed by means of TCP or UDP Transport Level (level 4) protocols.

For application level services, you can install OSI Services to run over the X.25 network (for more information, refer to OSI Services documentation). The OTS/9000 product provides access to X.25 for OSI Services. You can install application level services such as Internet/Berkeley Services and Network Services (for more information, refer to the documentation for these products).

BSD IPC (Berkeley Software Distribution InterProcess Communication) allows direct programmatic access to the X.25 packet level (level 3), or TCP/UDP at the transport level (level 4), for user-written application programs.

NetIPC sockets also provides a programmatic interface to TCP/UDP at the transport level.

Chapter 118

About the X.25 Product

Transport Level (L4)

At the transport level (level 4), the X.25 link provides TCP (based on the DARPA standard) and UDP. These Transport level protocols are used by Internet/Berkeley Services, by NS, and by user application programs that access the TCP/UDP and IP protocols.

The TCP protocol is a connection-based protocol. TCP verifies that all data is delivered without duplication to its destination. The UDP protocol, unlike TCP, has no concept of a connection. Messages are sent as a unit with source and destination information in the header.

The X.25 link provides a BSD to PLP (Packet Level Protocol) translator to allow access to PLP at level 3 for user-written application programs via BSD IPC.

The X.25 link also provides an OTS to PLP translator to allow access to PLP at level 3 for OSI Services via Xport OSI.

About the X.25 Product

Packet/network Level (L3)

At the packet/network level (L3), X.25 link provides direct X.25 programmatic access via BSD IPC. For full details on X.25 programmatic access, refer to the X.25/9000 Programmer’s guide (part number: J2793-90065).

The X.25 link also provides IP access to TCP or UDP Transport protocols for programs such as Internet/Berkeley Services and NS, allowing communication over X.25 in accordance with RFC 877.

About the X.25 Product

Data link (L2) and Physical (L1) Levels

At the data link level (level 2), the X.25 link provides the LAP-B (Link Access Procedure-Balanced) protocol. LAP-B is a data link protocol, specified by the 1980 CCITT X.25 recommendations, that determines frame exchange procedures.

At the physical level (level 1), the X.25 link provides support for X.21, X.21bis, and V.35 interfaces (depending on your particular communications hardware). These sets of recommendations define the standards for X.25 at the physical level and apply specifically to connections to a packet switching network. X.21bis (equivalent to V.24 and RS-232) is applicable to X.25 physical interfaces with transmission speeds up to 64 kb/s. V.35, RS-449, X.21, and RS-530 supports transmission speeds up to 2 Mb/s. Other standards may also be supported as they become available.

Installation

Before You Install the Software

Before installing the X.25 link software, check the requirements below to make sure that all required software and hardware has been correctly installed and configured.

NOTE This product is only supported on the system that is acting as a server. It

is not supported on client systems.

Hardware Requirements

This section describes the hardware requirements of the J2793B X.25 software for HP 9000 server systems.

If you have not already done so, install the X.25 interface card as described in the hardware installation guide for your X.25 product. If you are installing multiple X.25 cards, check the requirements in “Installing Multiple X.25 Interface Cards” below.

If a modem connection is required, connect the X.25 card to the modem or the modem eliminator according either to the modem vendor’s specification sheet, or the instructions provided by the network provider.

Installing Multiple X.25 Interface Cards

When installing multiple X.25 cards,

• Always install the cards in adjacent slots in ascending slot order.

• Always install X.25 cards with the system shut down.

• Do not skip slots between X.25 cards.

Hardware Compatibility

• HP 9000 PCI bus

The High Availability feature can run on:

• PCI hardware cards, Product Numbers J3525A (2-ports)

Installation

Before You Install the Software

OS Platform and Version Compatibility

The version of the X.25 link software you’re installing must be compatible with the version of HP-UX you’re running (for example, HP-UX version 11i v3 for B.11.31.01)

• Disk space required to install: 7 Mb

• Software install with system up or down? Up

• Single-user state required or recommended? No

• Reboot? Yes

Memory

Your X.25 link supports a high number of virtual circuits operating at high baud rates. Since both X.25 and the BSD sockets API may store a certain amount of data for each socket/circuit, HP recommends that you check that your system has enough memory to handle the number of VCs you plan to use. A few guidelines to help you are provided below.

Related Parameters

• Level 3 window size (W in formulas below) as configured in the x25config file

• Level 3 packet size (P in formulas below) as configured in X.25 configuration file

• Socket buffer size (B in formulas below) used in your applications (setsockopt() system call). The default is 4 Kb.

Evaluation Formulas The following formulas can be used to evaluate X.25 memory requirements:

Memory for each VC (MVC) in bytes:

MVC = (B x 3) + (2 x (W + 1) x P)

Total Memory (TM) for X.25 in bytes:

TM = sum (MVC) + Number of cards x 5120

NOTE These figures are only for protocol and API requirements. You should

also consider the memory required by your applications.

Chapter 2 25

Installation

Before You Install the Software

Shortcut Method Assuming B = P for all VCs, TM can be rounded to:

• If B < 512, TM = approx. (1,536 + (2 x W + 2) x B) x No. of VCs

• If B > or = 512, TM = approx. (2 x W + 5) x B x No. of VCs

The following table (in bytes/VC) provides a quick guide:

Window (W) size

Example 2-1 Example:

A system has two X.25 cards configured as follows:

Card 1:

Window = 2 Packet size = 1024 Socket buffer size = 4096 (default) 200 VCs are used

Card 2:

Window = 4 Packet size = 128 Socket buffer size = 4096 (default) 400 VCs are used

Configuring the X.25 Link

This section describes how to configure your X.25 link using HP System Management Homepage(SMH).

HP SMH provides Graphical User Interface (GUI), Terminal User Interface (TUI) and Command Line Interface (CLI) for managing HP-UX. You can access these interfaces using the smh command (/usr/sbin/smh).

If the DISPLAY environment variable is set, HP SMH opens in the default web browser. If the DISPLAY environment variable is not set, HP SMH opens in the TUI. For more information, see the HP-UX 11i v3 release notes and the SMH product online help.

In SMH, the term “card” refers to a particular X.25 interface. Dual-port cards have two interfaces. In this context, an interface is the same as a port.

NOTE System Administration Manager (SAM) is deprecated on HP-UX 11i v3

and replaced with the enhanced HP System Management Homepage (HP SMH). Users who attempt to start SAM from the command line interface are automatically redirected to the SMH user interface. SMH can be run directly in a web browser window by entering http://hostname:2301. In the Graphical User Interface (GUI), after logging in, the SMH main menu is displayed. Select Tools > networking and communications > network interface cards > choose X.25. For more information on SMH, see the HP System Management Homepage Release Notes (Part Number:381383-009) on http://docs.hp.com.
