Text conventions

The following conventions are used in this manual. Computer-generated text

is shown in typewriter font. Examples of computer-generated text are: program

output (such as the screen display during the software installation procedure),

commands, directory names, file names, variables, prompts, and sections of

program code.

Computer-generated text example

Commands to be entered by the user are printed in bold Courier type. For

example:

Introduction

1 Introduction

1.1 Overview

The EXN400 Ethernet Gateway; see Figure 1 on page 1 is a stand-alone

replaceable unit in a 1U height configuration (pizza box) that provides ATM

to Ethernet processing between various interfaces.

Figure 1 EXN410; Ethernet Gateway

As an off-the-shelf product, the EXN400 is manageable without additional

software add-ons. Management includes configuration and monitoring.

At initial installation, the user can access the EXN400 only through a TTY

console (parameters are 9600 baud, 8 data bits, 1 stop bit, no parity, no

flow control) or via Telnet by using the default settings mentioned in section

7.2.1 on page 155.

After management configuration, the user can also access the EXN400 on

a Telnet session (for more information see Management Configuration

Mode, section 2.11 on page 64 and Configuring Management, 5.3 on page

141).

1.3 Configuration Images

There are three images of the software configuration:

The running configuration is the configuration currently running. It is

stored in RAM. Therefore any change in configuration will not be taken

into account at next boot unless the running configuration is saved.

The startup configuration is the configuration that is taken into account

at boot time. It is stored in FLASH and can be updated.

The backup configuration is a copy of an operational configuration that

can be reactivated at any time. When configuration is saved in the

startup configuration, the previous startup configuration becomes the

backup configuration.

The software configuration can be downloaded from or saved to a

configuration file on an FTP/TFTP server. This file is not in a human-

readable format and should not be modified by the user.

1.4 Configuration Methods

Configuration is possible by using any of the following methods:

Entering commands on the Command line interface (CLI) through TTY

or remote shell

2 1553-LZY 214 2655 C 2004-11-24

Introduction

Preparing a script file including all the CLI commands, copying it on an

FTP server, and downloading the script file on the EXN400 by running

the script CLI command (for more information on script command,

see “script”, section 2.5.5 on page 14)

•

Downloading a configuration file on the EXN400 from an FTP server by

running the copy CLI command and rebooting to take the new

configuration into account (see “copy”, section 2.5.6 on page 15)

1.5 Management

A management entry point should be configured to:

Perform an FTP/TFTP connection

Run the ping command

Enable a telnet access to the EXN400

Enable SNMP management

Management can be configured through:

A single Ethernet interface or ATM PVC (for more information, see

Management Configuration Mode, section 2.11 on page 64)

A bridge (for more information, see Management Configuration Mode,

section 2.11 on page 64)

For a bridge, management will be available through any interface and/or

ATM PVC bound

to the bridge.

1.6 Initial Configuration

At first use, it is strongly recommended to configure:

The EXN400 name

The date and time

The Privileged EXEC password (if needed)

The ATM format

The system buffer pool

Command Line Interface

2 Command Line Interface

2.1 Overview

The Command Line Interface (CLI) is available through either a TTY

console or a Telnet session. Only one Telnet session can be open on an

EXN400 at a given time. To enable telnet access, at least one management

entry point must be configured (for more information, see Management

Configuration Mode, section 2.11 on page 64).

Several access levels are available:

User EXEC level: Only certain commands to view the EXN400 status

are available.

•

Privileged EXEC level: All the commands to view and configure the

EXN400 are available. A password may be required. Only one session

can enter Privileged EXEC level at a given time.

The EXN400 configuration exists in Global configuration and several

lower level configurations.

To illustrate this, several configuration modes are organized as shown in

Figure 2 on page 5.

The command line prompt identifies both the EXN400 name and the

command mode. The last character in the command prompt identifies the

access level, that is,

$ for a User EXEC level and # for a Privileged EXEC

level.
