INTRODUCTION
The DGS-1100-06/ME consists of 5 10/100/1000Mbps ports plus 1 100/100/SFP port.
The Switch can be managed through the Telnet or the Web-based management agent. The Command
Line Interface (CLI) can be used to configure and manage the Switch via the Telnet interfaces.
This manual provides a reference for all of the commands contained in the CLI. Configuration and
management of the Switch via the Web-based management agent is discussed in the Manual. For
detailed information on installing hardware please refer also to the Manual.
Setting the Switch’s IP Address
Each Switch must be assigned its own IP Address, which is used for communication with an SNMP
network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP
address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your
networking address scheme.
The Switch is also assigned a unique MAC address by the factory.
The Switch’s MAC address can also be found in the Web management program on the Switch Information
(Basic Settings) window in the Configuration folder.
The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch
IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address
assigned to the Switch must be known.
Alternatively, users can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP
address to be assigned to the IP interface named System and the z represents the corresponding number of
subnets in CIDR notation.
The IP interface named System on the Switch can be assigned an IP address and subnet mask which
can then be used to connect a management station to the Switch’s Telnet or Web-based management
agent.
Figure 1–1 Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.90.90.91 with a subnet mask of
255.0.0.0. The system message Success indicates that the command was executed successfully. The
Switch can now be configured and managed via Telnet, SNMP MIB browser and the CLI or via the Web-
based management agent using the above IP address to connect to the Switch.

USING THE COMMAND LINE INTERFACE
The Switch allows a computer or terminal to perform some basic monitoring and configuration tasks by
using the Command Line Interface (CLI) via TELNET protocol.
NOTE: Switch configuration settings are saved to non-volatile RAM using the save command.
The current configuration will then be retained in the Switch’s NV-RAM, and reloaded when the
Switch is rebooted. If the Switch is rebooted without using the save command, the last
configuration saved to NV-RAM is loaded.
The command line functions are accessed over a Telnet interface. Once an IP address for the Switch has
been set, A Telnet program can be used (in VT-100 compatible terminal mode) to access and control the
Switch.
After the Switch reboots and you have to logged in, the console looks like this:
Figure 2–1 Initial Console Screen after Logging In
Commands are entered at the command prompt, DGS-1100-06/ME:5#
There are a number of helpful features included in the CLI. Entering the ? command displays a list of all
of the top-level commands.
Figure 2–2 The ? Command
When entering a command without its required parameters, the CLI displays the prompt: command:
config account message and the options listed below.

DGS-1100-06/ME Metro Ethernet Managed Switch CLI Reference Guide

Figure 2–3 Example Command Parameter Help
In this case, the command config account was entered with the parameter <username>. The CLI will then
prompt to enter the <username> with the message, command: config account. Every command in the
CLI has this feature, and complex commands have several layers of parameter prompting.
In addition, after typing any given command plus one space, users can see all of the next possible sub-
commands, in sequential order, by pressing the ? key.
To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous
command appears at the command prompt.
Figure 2–4 Using the Up Arrow to Re-enter a Command
In the above example, the command config account was entered without the required parameter
<username>, the CLI returned the command: config account prompt. The up arrow cursor control key
was pressed to re-enter the previous command (config account) at the command prompt. Now the
appropriate username can be entered and the config account command re-executed.
All commands in the CLI function in this way. In addition, the syntax of the help prompts are the same as
presented in this manual angle brackets < > indicate a numerical value or character string. The < > can
also indicate a word with a number for character allowed.
If a command is entered that is unrecognized by the CLI, the top-level commands are displayed under
the Available commands: prompt.

Figure 2–5 Available Commands
The top-level commands consist of commands such as show or config. Most of these commands
require one or more parameters to narrow the top-level command. This is equivalent to show what? or
config what? Where the what? is the next parameter.
For example, entering the show command with no additional parameters, the CLI will then display all of
the possible next parameters.
Figure 2–6 Next possible completions: Show Command
In the above example, all of the possible next parameters for the show command are displayed. At the
next command prompt in the example, the up arrow was used to re-enter the show command, followed
by the account parameter. The CLI then displays the user accounts configured on the Switch.

COMMAND SYNTAX
The following symbols are used to describe how command entries are made and values and arguments
are specified in this manual. The online help contained in the CLI and available through the Telnet uses
the same syntax.
NOTE: All commands are case-sensitive. Be sure to disable Caps Lock or any other unwanted
function that changes text case.

Purpose
Encloses a variable or value that must be specified.
Syntax
