Chapter 1 Using Command Line
Interface
The Switch can be managed through the Switch’s Command Line Interface (CLI), Web User
Interface (Web UI) and by using the Simple Network Management Protocol (SNMP). 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. Every command
will be introduced in terms of purpose, format, description, parameters, and examples.
Configuration and management of the Switch via the Web UI is discussed in the Web UI
Reference Guide. For detailed information on installing hardware please also refer to the Hardware
Installation Guide.
1-1 Accessing the Switch via the Serial Port
The front panel of the Switch provides a port that enables a connection to a computer monitoring
and configuring the Switch. The console port is an RJ-45 port and requires a special cable that is
included with the Switch, to establish the physical connection.
To use the console port, the following equipment is needed:
1. A terminal or a computer with both an RS-232 serial port and the ability to emulate a
terminal.
2. A console cable with a male DB-9 connector on one end and an RJ-45 connection on the
other. This cable should be included with the Switch. It establishes the physical connection
to the console port.
Connect the male DB-9 connector on the console cable (shipped with the Switch) to the RS-232
serial port on the computer running terminal emulation software then insert the RJ-45 connector
into the RJ-45 console port on the front of the Switch.
Using a terminal to connect to the console port:
Set the terminal emulation software as follows:
Select the appropriate serial port (COM1 or COM2).
Set the data rate to 115200 baud.
Set the data format to 8 data bits, 1 stop bit, and no parity.
Set flow control to none.
Under Properties, select VT100 for Emulation mode.
Select Terminal keys for Function, Arrow and Ctrl keys. Make sure to use Terminal keys (not
Windows keys) are selected.
NOTE:When using HyperTerminal with the Microsoft® Windows® 2000 operating
system, ensure that Windows 2000 Service Pack 2 or later is installed. Windows
2000 Service Pack 2 allows use of arrow keys in HyperTerminal's VT100 emulation.
See www.microsoft.com for information on Windows 2000 service packs.

After correctly configuring the terminal, plug the power cable into the power receptacle on the back
of the Switch. The boot sequence will appear in the terminal.

After the boot sequence has been completed, the console login screen will be displayed.
The Switch supports user-based security that can allow prevention of unauthorized users from
accessing the Switch or changing its settings. This section will explain how to log into the Switch’s
Command Line Interface via the out-of-band console connection.
Upon initial connection to the Switch, the login screen appears (see example below).

UserName:
PassWord:
DWS-3160-24PC:admin#
By default, there is no Username and Password configured in the account settings of this Switch.
This will allow the user to simply connect to this Switch for the first time by pressing the ‘Enter’ key
twice.
After press Enter for both the Username and Password fields, access will be given to enter
commands after the command prompt (DWS-3160-24PC:admin#) appears.

NOTE: The first user automatically gets Administrator level privileges. At least one
Admin-level user account must be created for the Switch.
1-2 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 applications. The Switch's default IP address is
10.90.90.90. You can change the Switch’s default IP address to fit into your networking address
range.
The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be
changed, and can be found by entering the command "show switch" into the command line
interface, as displayed below.
DWS-3160-24PC:admin#show switch
Command: show switch
Device Type : DWS-3160-24PC Gigabit Ethernet Switch
MAC Address : 00-11-22-33-45-67
IP Address : 10.90.90.90 (Manual)
VLAN Name : default
Subnet Mask : 255.0.0.0

The IP address of the Switch must be configured before it can be managed, by the user, via the
Web User Interface.
An example to change the IP address of the Switch to ’10.90.90.91’, using a subnet mask of
‘255.0.0.0’:

DWS-3160 Series Gigabit Ethernet Unified Switch CLI Reference Guide
4
DWS-3160-24PC:admin#config ipif System ipaddress 10.90.90.91/8
Command: config ipif System ipaddress 10.90.90.91/8
Success.
DWS-3160-24PC:admin#
•At the CLI command prompt, enter the ‘config ipif System ipaddress 10.90.90.91/8’
command and press ‘Enter’. This will change the IP address of the Switch to 10.90.90.91.
•Also notice the subnet mask’s notation method. Here we use the value ‘/8’ which means
that the subnet mask will be change to 255.0.0.0 using the CIDR notation.
•Alternatively, if you don’t know the CIDR notation for your subnet mask, you can also
simply type out the subnet mask. For example: ‘config ipif System ipaddress
10.90.90.91/255.0.0.0’.
The Switch can now be configured and accessed using TELNET or the Web-based management.
The Switch’s IP address can also automatically be obtained by using the BOOTP or DHCP
protocol.
There are a number of helpful features included in the CLI. Entering the ‘?’ command will display a
list of all of the top-level commands.

DWS-3160-24PC:admin# config account
Command: config account
Next possible completions:

DWS-3160-24PC:admin#
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, 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.
If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed
under the Available commands: prompt.

DWS-3160-24PC:admin#
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.
