xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual 
1 
INTRODUCTION 
The DGS-3400 Series is a member of the D-Link xStack switch family. xStack is a complete family of stackable devices that 
ranges from edge 10/100Mbps switches to core Gigabit switches. xStack provides unsurpassed performance, fault tolerance, 
scalable flexibility, robust security, standard-based interoperability and an impressive support for 10Gigabit technology to future-
proof departmental and enterprise network deployments with an easy migration path. 
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. For detailed information on installing hardware please refer also to 
the Manual. 
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 o refresh the console screen.

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3400:4#. 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. 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.
