INTRODUCTION
The DGS/DXS-3300 Layer 3 stackable Gigabit Ethernet switches are members of the D-Link xStack family. Ranging from
10/100Mbps edge switches to core gigabit switches, the xStack switch family has been future-proof 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 members of the xStack DGS/DXS-3300
series, including the DGS-3324SRi, DGS-3324SR, DXS-3326GSR, and the DXS-3350SR. Examples present in this manual
may refer to any member of the xStack DGS/DXS-3300 series and may show different port counts, but are universal to this
series of switches, unless otherwise stated. Configuration and management of the Switch via the Web-based management agent
is discussed in the User’s Guide.
Please take note that if this device was purchased outside of Europe, certain cosmetic differences between the actual switch and
images in this document will be apparent to the reader, such as the faceplate and the manual cover. Changes are made to the
appearance of the device only and no configuration or internal hardware alterations occur.
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.
Accessing the Switch via the Serial Port
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 is 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 −DGS-3324SRi:4#.
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. The default switch IP address
can be changed 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 address 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 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:
1. Starting at the command line prompt, enter the commands 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.
2. Alternatively, the user may 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 zrepresents 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 1-3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.53.13.144 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 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 xStack DGS/DXS-3300 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 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 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
The same functions can be accessed over a Telnet interface. Once an IP address has been set for your Switch, a Telnet program
(in VT-100 compatible terminal mode) can be used 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 the user has logged in, the console looks like this:

Figure 2-1. Initial Console Screen
Commands are entered at the command prompts, DGS-3324SRi:4#, DGS-3324SR:4#, DXS-3326GSR:4#, DXS-3350SR:4#.
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.
Figure 2-2. The ? Command
When a command has been entered without its required parameters, the CLI will prompt a Next possible completions: message.

xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch CLI Manual

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, 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, all of the next possible sub-commands can be viewed, 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 User name 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.
Figure 2-5. The Available Commands Prompt
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, if the show command has been entered 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,
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 console interface 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.
<angle brackets>
Purpose Encloses a variable or value that must be specified.
Syntax create ipif <ipif_name> <network_address> <vlan_name
32> {secondary | state [enable | disable]}
Description In the above syntax example, supply an IP interface name in the
<ipif_name> space, a VLAN name in the <vlan_name 32>
space, and the network address in the <network_address>
space. Do not type the angle brackets.
Example Command create ipif Engineering 10.24.22.5/255.0.0.0 Design
[square brackets]
Purpose Encloses a required value or set of required arguments. One
value or argument can be specified.
Syntax create account [admin | user] <username 15>
Description In the above syntax example, specify either an admin or a user
level account to be created. Do not type the square brackets.
Example Command create account admin
| vertical bar
Purpose Separates two or more mutually exclusive items in a list, one of
which must be entered.
Syntax create account [admin | user] <username 15>
Description In the above syntax example, it is necessary to specify either
admin, or user. Do not type the backslash.
Example Command create account admin

{braces}
Purpose Encloses an optional value or set of optional arguments.
Syntax reset {[config | system]}
Description In the above syntax example, the user has the option to specify
config or system. It is not necessary to specify either optional
value, however the effect of the system reset is dependent on
which, if any, value is specified. Therefore, with this example
there are three possible outcomes of performing a system
reset. See the following chapter, Basic Commands for more
details about the reset command.
Example command reset config
