Chapter 1 Using the Command
Line Interface
The DGS-3620 Layer 3 stackable Gigabit Ethernet switch series are members of the D-Link
xStack® family. Ranging from 10/100/1000Mbps 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.
The Switch can be managed through the Switch’s serial port, Telnet, SNMP 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. Every command
will be introduced in terms of purpose, format, description, parameters, and examples.
Configuration and management of the Switch via the Web-based management agent are
discussed in the Web UI Reference Guide. For detailed information on installing hardware please
also refer to the Harware Installation Guide.
1-1 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 RJ-45 to RS-
232 DB-9 convertor cable.
With the serial port properly connected to a management computer, the following screen should be
visible.

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 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. This MAC address cannot be
changed, and can be found on the initial boot console screen – shown below.
Boot Procedure V1.00.016
-------------------------------------------------------------------------------

UART init ................................................. 100 %
Starting runtime image
Device Discovery .......................................... 100 %
Configuration init ........................................ 100 %
Press any key to login...
The Switch’s MAC address can also be found in the Web management program on the Device
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.
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.
Alternatively, you 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 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

DGS-3620-28SC:admin# config ipif System ipaddress 10.24.22.100/255.0.0.0
Command: config ipif System ipaddress 10.24.22.100/8
Success.
DGS-3620-28SC:admin#
In the above example, the Switch was assigned an IP address of 10.24.22.100 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.
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.

DGS-3620-28SC:admin#config account
Command: config account
Next possible completions:
<username 15>
DGS-3620-28SC: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.
DGS-3620-28SC:admin#config account
Command: config account
Next possible completions:
<username 15>
DGS-3620-28SC:admin#
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 commands: prompt.
