# About This Guide

## How to use this guide

This guide explains how to configure and use the MAX as an Internet Service Provider (ISP) or telecommuting hub. Following is a chapter-by-chapter description of the topics:

- Chapter 1, "MAX System Administration," explains how to administer and manage the MAX.

- Chapter 2, "VT100 Interface DO Commands," describes each of the VT100 interface DO commands in alphabetic order.

- Chapter 3, "Diagnostic Commands and Parameters," lists and explains the diagnostic commands provided for WAN lines and ports.

- Chapter 4, "VT100 Interface Status Windows," describes status windows in alphabetic order.

- Chapter 5, "Network Administration," discusses how to perform line diagnostic commands on BRI lines, how to remove digital modems from service, and how to display call information. The chapter also discusses administering and managing TCP/IP and IPX networks.

- Chapter 6, "SNMP and Syslog Configuration," explains how to configure SNMP and Syslog support.

- Appendix A, "Troubleshooting," discusses common problems and offers possible solutions.

- Appendix B, "MAX Diagnostic Command Reference," lists and explains the most helpful commands available from diagnostic mode on the MAX. The chapter includes a discussion of decoding Point-to-Point (PPP) packet traces.

- Appendix C, "Upgrading System Software," explains how to upgrade the MAX system software.

- Appendix D, "Example environments," discusses example environments, including an IP-routing environment and an IP-routing/AppleTalk environment.

This guide also includes an index.

## What you should know

This guide is for the person who configures and maintains the MAX. To configure the MAX, you need to understand the following:

- Wide area network (WAN) concepts

- Local area network (LAN) concepts, if applicable

## Documentation conventions

Following are all the special characters and typographical conventions used in this manual:

#### Convention | #### Meaning
--- | ---
`Monospace text` | Represents text that appears on your computer's screen, or that could appear on your computer's screen.
Boldface mono-space text | Represents characters that you enter exactly as shown (unless the characters are also in italics-see Italics, below). If you could enter the characters but are not specifically instructed to, they do not appear in boldface.
Italics | Represent variable information. Do not enter the words themselves in the command. Enter the information they represent. In ordinary text, italics are used for titles of publications, for some terms that would otherwise be in quotation marks, and to show emphasis.
[ ] | Square brackets indicate an optional argument you might add to a command. To include such an argument, type only the information inside the brackets. Do not type the brackets unless they appear in bold type.
| | Separates command choices that are mutually exclusive.
> | Points to the next level in the path to a parameter or menu item. The item that follows the angle bracket is one of the options that appears when you select the item that precedes the angle bracket.
Key1-Key2 | Represents a combination keystroke. To enter a combination keystroke, press the first key and hold it down while you press one or more other keys. Release all the keys at the same time. (For example, Ctrl-H means hold down the Control key and press the H key.)
Press Enter | Means press the Enter, or Return, key or its equivalent on your computer.
Note: | Introduces important additional information.
Caution: | Warns that a failure to follow the recommended procedure could result in loss of data or damage to equipment.
Warning: | Warns that a failure to take appropriate safety precautions could result in physical injury.

Note: In a menu-item path, include a space before and after each ">" character.
