1.3 Firmware Overview
1.3.1 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:
ML810#
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.
1.3.2 EnerVista Software
Icons common to the EnerVista MultiLink Secure Web Management (SWM) firmware for
edit, delete, save and refresh are:
• Edit - edit the values
• Delete - delete the current row or the value(s)
• Save - save configuration changes
• Refresh - repaint the screen
1.3.3 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.

CHAPTER 1: SPECIFICATIONS FIRMWARE OVERVIEW
MULTILINK ML810 MANAGED EDGE SWITCH – INSTRUCTION MANUAL 1–7
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.

COMMAND LINE INTERFACE FIRMWARE CHAPTER 1: SPECIFICATIONS
1.4 Command Line Interface Firmware
1.4.1 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.
1.4.2 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
1.4.3 Console Screen
Once the console cable is connected to the PC and the firmware configured, ML810 legal
disclaimers and other text scrolls by on the screen.

CHAPTER 1: SPECIFICATIONS COMMAND LINE INTERFACE FIRMWARE
MULTILINK ML810 MANAGED EDGE SWITCH – INSTRUCTION MANUAL 1–9
The line interface prompt appears displaying the switch model number (e.g. ML810>)
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.
•ML810>
Operator Level - for running operations queries
•ML810#
Manager Level - for setting and reviewing commands
•ML810##
Configuration Level - for changing the switch parameter values
For additional information on default users, user levels and more, refer to User
Management on page 1–12.
1.4.4 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.
1.4.5 Automatic IP Address Configuration
The ML810 is operational immediately after it is powered up. The advanced management
and configuration capabilities of the ML810 allows you to easily configure, manage, and
secure your devices and network.
Before starting, ensure you have the following items:
• RJ45 Ethernet cable
•PCwithanEthernetport
• 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 ML810 can search the network for commonly used services that can issue an IP
address. If the switch is connected to a network, the ML810 uses the following process to
find an IP address.
If the ML810 is not connected to a network, then proceed to Step 3 below. or use the
default IP address.
Step 1:
The ML810 will scan the network for a DHCP server. If the server responds, the ML810 will
acquire and set the assigned IP address. To manage the switch, determine the assigned IP
address and enter as follows in Internet Explorer:

1–10 MULTILINK ML810 MANAGED EDGE SWITCH – INSTRUCTION MANUAL
COMMAND LINE INTERFACE FIRMWARE CHAPTER 1: SPECIFICATIONS
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 ML810 will query for a BOOTP server. If the
server responds, the ML810 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 ML810 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 ML810 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
1.4.6 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.
Ensure the power is off.
Follow the steps described above for connecting the console cable and
setting the console firmware.
Power on the switch.
Once the login prompt appears, login as manager using default
password (manager).
Configure the IP address, network mask and default gateway as per the
IP addressing scheme for your network.
Set the manager password (this step is recommended; refer to the
following section).
Save the settings (without saving, the changes made will be lost).
Power off the switch (or a firmware reboot as discussed below).
Power on the switch - login with the new login name and password.
