INTRODUCTION
The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The Command Line
Interface (CLI) can be used to configure and manage the Switch via the serial port or 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. Configuration and management of the Switch via the Web-based
management agent is discussed in the User’s Guide.
Accessing the Switch via the Serial Port
The Switch’s serial port’s default settings are as follows:
•9600 baud
•no parity
•8 data bits
•1 stop bit
A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above
are then connected to the Switch’s serial port via an RJ-45 console cable.
With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not
appear, try pressing Ctrl+R to refresh the console screen.

PassWord:
Figure 1 - 1. Initial CLI screen
There is no initial username or password. Just press the Enter key twice to display the CLI input cursor −DES-1228/ME:5#. This
is the command line where all commands are input.
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. Users 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. This MAC address cannot be changed, and can be found on the
initial boot console screen – shown below.
Boot Procedure V2.00.001
-------------------------------------------------------------------------------
Power On Self Test ........................................ 100%
MAC Address : 00-12-28-8E-77-00
H/W Version : B1
Please wait, loading V2.01.001 Runtime image .............. 100%
Figure 1 - 2. Boot screen
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.
The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

DES-1228/ME Metro Ethernet Managed Switch CLI Reference Guide

Starting at the command line prompt, enter the command config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where
the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet
mask.
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.
DES-1228/ME:5#config ipif System ipaddress 10.73.21.11/8
Command: config ipif System ipaddress 10.73.21.11/8
Success.
DES-1228/ME:5#
Figure 1 - 3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.73.21.11 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 CONSOLE CLI
The Switch supports a console management interface that allows the user to connect to the Switch’s management agent via a serial
port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the
TCP/IP Telnet protocol. The console program can be used to configure the Switch to use an SNMP-based network management
application over the network.
This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation.
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 will be
loaded.
Connecting to the Switch
The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary
terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RJ-45
console cable. Your terminal parameters will need to be set to:
•VT-100 compatible
•9600 baud
•8 data bits
•No parity
•One stop bit
•No flow control
Users can also access the same functions over a Telnet interface. Once users have set an IP address for your Switch, users can use
a Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether
accessed from the console port or from a Telnet interface.
After the Switch reboots and users have logged in, the console looks like this:

In this case, the command config account was entered without the parameter <username>. The CLI will then prompt users to enter
the <username> with the message, Next possible completions:. 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 repeatedly pressing the Tab key.
To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous command will appear 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
Next possible completions: <username> 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, braces { } indicate optional parameters or a choice of
parameters, and brackets [ ] indicate required parameters.
If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed under the Available
