1.4 Firmware Overview

1.4.1 Command Line Firmware

Commands typed by the user will be shown in the following color and font.

command

The MultiLink Switch Software prompt will be shown in bold and fixed-width text , with a #
or

> character at the end. The default prompt is indicated as follows:

ML2400#

The following hold for syntax rules:

• Syntax rules are italicized

• The command part is in bold

• Optional entries are shown in [square brackets]

• Parameter values within are shown in <pointed brackets>

• Optional parameter values are shown again in [square brackets]

Thus, the syntax

command [parameter1=<value1>[,paramter2=<value2>]]
parameter3=<value3|value4>

indicates the following:

• parameters 1 and 2 are optional

• parameter 2 can be used optionally only if parameter 1 is specified

• parameter 3 is mandatory.

Whenever the word PC is used, it implies a UNIX, Linux, Windows, or any other operating
system based workstation, computer, personal computer, laptop, notebook or any other
computing device. Most of the manual uses Windows XP based examples. While effort has
been made to indicate other operating system interactions, it is best to use a Windows-XP
based machine when in doubt.

The documentation reflects features of MultiLink Switch Software version 1.7.x or later. If
your switch is not at the current version, GE Multilin recommends upgrade to version 1.7.x
or later. Please refer to the GE Multilin website for information on upgrading the MultiLink
Switch Software.

CHAPTER 1: INTRODUCTION INTRODUCTION

1.4.3 Before Starting

This section explains how to setup the GE MultiLink family of switches using the console
port on the switch. Some of the functionality includes setting up the IP address of the
switch, securing the switch with a user name and password, setting up VLANs and more.

Before you start, it is recommended to acquire the hardware listed below and be ready
with the items listed.

For initial configuration through the serial/console port:

1. A female-female null modem cable.

2. A serial port . If your PC does not have a serial port, you may want to invest in
a USB-to-serial converter or USB-to-serial cable.

3. Terminal emulation firmware such as HyperTerminal or other equivalent
firmware. Ensure the firmware supports Xmodem protocol, as you may need
this in the future to update the MultiLink Switch Software.

4. Enough disk space to store and retrieve the configuration files as well as copy
firmware files. We recommend at least 15 MB of disk space for this purpose.

5. For access security - decide on a manager level account name and password

6. IP address, netmask, default gateway for the switch being configured.

As a default, the switch has no IP (Internet Protocol) address and subnet mask. For first
time use, the IP address has to be assigned. This can only be done by using the console
interface provided.

The same procedure can also be used for other configuration changes or updates (for
example, changing the IP address, VLAN assignments and more). Once the IP address is
assigned and a PC is networked to the switch, the switch's command line interface (CLI)
can be accessed via telnet. To manage the switch through in-band (networked) access
(e.g. telnet, or web browser Interface), you should configure the switch with an IP address
and subnet mask compatible with your network. Also, change the manager password to
control access privileges from the console.

Many other features such as optimizing the switch's performance, traffic engineering and
traffic prioritizing, VLAN configuration, and improving network security can be configured
through the switch's console interface as well as in-band (networked) access, once the IP
address is setup. Besides the IP address, setting up the SNMP parameters allows
configuration and monitoring through an SNMP network management station running a
network management program.

MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 1–9

INTRODUCTION CHAPTER 1: INTRODUCTION

1.5 Command Line Interface Firmware

1.5.1 Console Connection

The connection to the console is accessed through the DB-9 RS232 connector on the
switch marked as the console port. This command line interface (or CLI) provides access to
the switch commands. It can be accessed by attaching a VT100 compatible terminal or a
PC running terminal emulation firmware to the console port.

USB-to-serial adapters are also available for computers that do not native serial ports but
have access to USB ports.

The interface through the console or the console management interface (or CMI) enables
you to reconfigure the switch and to monitor switch status and performance.

Once the switch is configured with an IP address, the command line interface (or CLI) is
also accessible using telnet as well as the serial port. Access to the switch can be either
through the console interface or remotely over the network. Simultaneous access (that is,
through the console port as well as through the network) to the MultiLink switch is not
permitted.

The Command Line Interface (CLI) enables local or remote unit installation and
maintenance. The MultiLink family of switches provides a set of system commands which
allow effective monitoring, configuration and debugging of the devices on the network.

1.5.2 Console Setup

Connect the console port on the switch to the serial port on the computer using the serial
cable listed above. The settings for the HyperTerminal firmware emulating a VT100 are
shown below. Make sure the serial parameters are set as shown (or bps = 38400, data bits
= 8, parity = none, stop bits = 1, flow control = none).

FIGURE 1–1: Serial Settings in HyperTerminal

1–10 MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 1: INTRODUCTION INTRODUCTION

1.5.3 Console Screen

Once the console cable is connected to the PC and the firmware configured, ML2400 legal
disclaimers and other text scrolls by on the screen.

The line interface prompt appears displaying the switch model number (e.g. ML2400>)

The switch has three modes of operation: operator (least privilege), manager, and
configuration. The prompts for the switches change as the switch changes modes from
operator to manager to configuration. The prompts are shown below with a brief
description.

• ML2400>

Operator Level - for running operations queries

• ML2400#

Manager Level - for setting and reviewing commands

• ML2400##

Configuration Level - for changing the switch parameter values

For additional information on default users, user levels and more, refer to User
Management on page 1–14.

1.5.4 Logging In for the First Time

For the first time, use the default user name and passwords assigned by GE. They are:

•Username: manager
Password: manager

•Username: operator
Password: operator

We recommend you login as manager for the first time to set up the IP address as well as
change user passwords or create new users.

1.5.5 Automatic IP Address Configuration

The ML2400 is operational immediately after it is powered up. The advanced management
and configuration capabilities of the ML2400 allows you to easily configure, manage, and
secure your devices and network.

Before starting, ensure you have the following items:

• RJ45 Ethernet cable

•PC with an Ethernet port

• Microsoft Internet Explorer 6.0 or higher

• Macromedia Flash Player 5.0 or higher (available from http://

www.macromedia.com/shockwave/download/
download.cgi?P1_Prod_Version=ShockwaveFlash)

Ensure both firmware components are installed before proceeding.

The ML2400 can search the network for commonly used services that can issue an IP
address. If the switch is connected to a network, the ML2400 uses the following process to
find an IP address.

MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 1–11

INTRODUCTION CHAPTER 1: INTRODUCTION

Note

If the ML2400 is not connected to a network, then proceed to Step 3 below. or use the
default IP address.

Step 1:

The ML2400 will scan the network for a DHCP server. If the server responds, the ML2400
will acquire and set the assigned IP address. To manage the switch, determine the
assigned IP address and enter as follows in Internet Explorer:

https://

<assigned_IP_address>

Ensure that https is entered, not http, and that there is connectivity (that is, you can ping
the switch).

Step 2:

If there is no response from a DCHP server, the ML2400 will query for a BOOTP server. If the
server responds, the ML2400 will acquire and set the assigned IP address. To manage the
switch, determine the assigned IP address and enter as follows in Internet Explorer:

https://

<assigned_IP_address>

Ensure that https is entered, not http, and that there is connectivity (that is, you can ping
the switch).

Step 3:

If there is no response from either a DCHP or BOOTP server, or if the switch is not
connected to a network, the switch will assign itself an IP address. The ML2400 will check
to see if IP address 192.168.1.2, with a network mask of 255.255.255.0, is free. If so, it will
assume these values. If this IP address is assigned to another device, the ML2400 will
repeat steps 1 through 3 to find a DCHP or BOOTP server or wait for the 192.168.1.2
address to become free.

Once connected, the browser will display a login prompt. The default login is:

•Username: manager
Password: manager

1.5.6 Setting the IP Parameters

To setup the switch, the IP address and other relevant TCP/IP parameters have to be
specified.

The IP address on the MultiLink switch is set to 192.168.1.2 from the factory. The switch is
fully operational as a Layer 2 switch as a default. Setting a default IP address can
potentially cause duplicate IP address problem if multiple switches are powered on and
installed on the network. To manage the switch, an IP address has to be programmed.

Before starting, please ensure that the IP address assigned to the switch is known or
contact your system/network administrator to get the IP address information. Follow the
steps listed below to configure the switch.

Z Ensure the power is off.

Z Follow the steps described above for connecting the console cable

and setting the console firmware.

Z Power on the switch.

1–12 MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 1: INTRODUCTION INTRODUCTION

Z Once the login prompt appears, login as manager using default

password (manager).

Z Configure the IP address, network mask and default gateway as per

the IP addressing scheme for your network.

Z Set the manager password (this step is recommended; refer to the

following section).

Z Save the settings (without saving, the changes made will be lost).

Z Power off the switch (or a firmware reboot as discussed below).

Z Power on the switch - login with the new login name and password.

Z From the PC (or from the switch) ping the IP address specified for the

switch to ensure connectivity.

Z From the switch ping the default gateway specified (ensure you are

connected to the network to check for connectivity) to ensure
network connectivity.

Syntax:

ipconfig [ip=<ip-address>] [mask=<subnet-mask>] [dgw=<gateway>]

An example is shown below.

ML2400# ipconfig ip=3.94.247.41 mask=255.255.252.0

dgw=3.94.247.41

ML2400# save

Note

This manual assumes the reader is familiar with IP addressing schemes as well as how net
mask is used and how default gateways and routers are used in a network.

Reboot gives an opportunity to save the configuration prior to shutdown. For a reboot,
simply type in the command

reboot. Note that even though the passwords are not

changed, they can be changed later.

ML2400# reboot

Proceed on rebooting the switch? ['Y' or 'N'] Y

Do you wish to save current configuration? ['Y' or 'N'] Y

ML2400#

The ML2400 forces an answer by prompting with a “Y” or a “N” to prevent accidental
keystroke errors and loss of work.

The parameters can be viewed at any time by using the

show command. The show

command will be covered in more detail later in various sections throughout the
document.

The example below illustrates the basic setup parameters. You can use

show setup or

show sysconfig commands to view setup parameters.

Some of the parameters in the MultiLink family of switches are shown above. The list of
parameters below indicates some of the key parameters on the switch and the
recommendations for changing them (or optionally keeping them the same).

1.5.7 Privilege Levels

Two privilege levels are available - manager and operator. Operator is at privilege level 1
and the manager is at privilege level 2 (the privilege increases with the levels). For example,
to set up a user for basic monitoring capabilities use lower number or operator level
privilege (level 1).

The Manager level provides all operator level privileges plus the ability to perform system­level actions and configuration commands. To select this level, enter the

name>

prompted.

For example, switching from an operator-level to manager-level, using the
command is shown below.

Note the prompt changes with the new privilege level.

Operator privileges allow views of the current configurations but do not allow changes to
the configuration. A “>” character delimits the operator-level prompt.

Manager privileges allow configuration changes. The changes can be done at the
manager prompt or for global configuration as well as specific configuration. A “#”
character delimits any manager prompt.

enable <user-

command at the Operator level prompt and enter the Manager password, when
