The

CoreBuilder

9000 ATM Enterprise Switch User Guide

provides all the

information that you need to configure and set up the CoreBuilder 9000

ATM Enterprise Switch in ATM networking environments. It also provides

information about how the CoreBuilder 9000 ATM Enterprise Switch

operates in an ATM network.

This guide is intended for the system administrator, network equipment

technician, or network manager who is responsible for installing,

managing, and operating a network that is based on the

CoreBuilder 9000 ATM Enterprise Switch. It assumes a working

knowledge of network operations and familiarity with communications

protocols that are used in networks. No prior knowledge of 3Com’s

CoreBuilder networking equipment is necessary to understand the

information in this manual.

If the information in the release notes that are shipped with this product

differs from the information in this guide, follow the instructions in the

release notes.

Most user guides and release notes are available in Adobe Acrobat

Convention Description

Screen displays

This typeface represents information as it appears on the

screen.

Syntax

The word “syntax” means that you must evaluate the syntax

provided and then supply the appropriate values for the

placeholders that appear in angle brackets. Example:

To enable RIPIP, use the following syntax:

SETDefault !<port> -RIPIP CONTrol =

Listen

In this example, you must supply a port number for <port>.

Commands

The word “command” means that you must enter the

command exactly as shown and then press Return or Enter.

Commands appear in bold. Example:

To remove the IP address, enter the following command:

SETDefault !0 -IP NETaddr = 0.0.0.0

The words “enter”

and “type”

When you see the word “enter” in this guide, you must type

something, and then press Return or Enter. Do not press

Return or Enter when an instruction simply says “type.”

Keyboard key names If you must press two or more keys simultaneously, the key

names are linked with a plus sign (+). Example:

Press Ctrl+Alt+Del
