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.
The DES-3528/DES-3552 Series Layer 2 stackable Fast Et hernet Switch Ser ies are members of the D-Link xStack
®
family. Ranging from 10/100Mbps edge Switches to core gigabit Switches, the xStack Switch family has been futureproof designed to provide a stacking architecture with fault tolerance, flexibility, port density, robust security and
maximum throughput with a user-friendly management interface for the networking professional.
This manual provides a reference for all of the commands contained in the CLI for the xStack
®
DES-3528, DES3528P, DES-3528DC, DE S-3552 and DES-3552P s eries of Switches. Conf iguration and management of the Switch
via the Web-based management agent is discussed in the User’s Guide.
NOTE: For the remainder of this manual, all versions of the DES-3528, DES-3528P, DES-3528DC,
DES-3552 and DES-3552P Switches will be referred to as simply the Switch or the DES-3528/52
Series.
Accessing the Switch via the Serial Por t
The Switch’s serial port’s default settings are as follows:
• 115200 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 RS-232 DB-9 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.

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-
3528:admin# . 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 m anager
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.

Figure 1-2. Boot screen
The Switch’s MAC addres s can also be found in the Web management program on the Switch Information (Basic
Settings) window on the Configuration menu.
The IP address for the Switc h must be set before it can be managed with t he Web-based manager. The Switch I P
address can be autom aticall y set using BO OTP or DH CP protoc ols, in whic h case the actual a ddress as signed to th e
Switch must be known.
The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:
1. Starting at the command line prompt, enter the commands config ipif System ipaddress
xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. W her e the x’s r epresent the IP addres s to be assigned to the IP int erface
named System and the y’s represent the corresponding subnet mask.
2. Alternatively, users can enter conf ig ipif System ipa ddress xxx.xxx.x xx.xxx/z. Where the x’s represent the
IP address to be as sig ned t o the IP i nterfac e nam ed System and the z represents the cor respon ding num ber
of subnets in CIDR notation.
The IP interface nam ed System on the Switch can be assigned an IP address and s ubnet mask which can then be
used to connect a management station to the Switch’s Telnet or Web-based management agent.
DES-3528:admin# config ipif System ipaddress 10.24.73.21/8
Command: config ipif System ipaddress 10.24.73.21/8
Success.
DES-3528:admin#
Figure 1-3. Assigning an IP Address screen
In the above exam ple, the Switch was assigned an IP address of 10.24. 73.21 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, S NMP MIB browser and the CLI or via the W eb-based management agent using t he above
IP address to connect to the Switch.

USING THE CONSOLE CLI
The DES-3528/52 Series 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 software 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 re loa ded when the S witc h 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 Switc h to a VT100-compatible terminal or a computer runni ng an
ordinary terminal em ulator program (e.g., the HyperTerminal program included with the W indows operating system )
using an RS-232C serial cable. Your terminal parameters will need to be set to:
• VT-100 compatible
• 115200 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:

Figure 2-2. The ? Command
When users enter a command without its required parameters, the CLI will prompt users with a Next possible
completions: message.
DES-3528:admin# config account
Command: config account
Next possible completions:
<username>
DES-3528:admin#
Figure 2-3. Example Command Parameter Help
In this case, the comm and config account was entered with the parameter <username>. The CLI will then prompt
users to enter the <username> with the m essage, Next possible completions:. Every command in the CLI has this
feature, and complex commands have several layers of parameter prompting.
In addition, after typing an y given comm and plus one space, users can see all of the next possib le sub-c omm ands, in
sequential order, by repeatedly pressing the Tab key.
To re-enter the previous command at the comm and prompt, press the up arro w cursor key. The previou s command
will appear at the command prompt.

Figure 2-4. Using the Up Arrow to Re-enter a Command
In the above example, the comm and config account was entered without the requ ired parameter <username>, the
CLI returned the Next possible completions: <username> prompt. The up arrow cursor contr ol key was pres sed to
re-enter the previous comm and (config account) at the command prompt. Now the appropriat e 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 commands: prompt.
