INTRODUCTION
The xStack® DGS–3400 Series is a member of the D–Link xStack® switch family. xStack® is a complete family of stackable
switches that range from edge 10/100Mbps switches to core Gigabit switches. xStack
tolerance, scalable flexibility, robust security, standard–based interoperability and an impressive support for 10–Gigabit
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.

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–3426:5#. 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 chang ed, 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, 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 z represents 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–3426:5#config ipif System ipaddress 10.73.21.35/255.0.0.0
Command:config ipif System ipaddress 10.73.21.35/8
Success.
Figure 1–3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.73.21.35 with a subn et mask of 255 .0 .0.0 . Th e 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.
Note: The DGS–3400 series of switches have the capability to be configured for an IP address of
0.0.0.0, or, in essence, have no IP address. This function maybe used to disable Layer 3 functions
of the Switch. When the IP address is set to 0.0.0.0 (invalid IP address), the Switch can only be
managed through the console port or SIM. Other management applications such as Telnet, Web–
based and SNMP cannot be used to manage the Switch when its IP address is 0.0.0.0.

USING THE CONSOLE CLI
The Switch 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
Users may also access the same functions over a Telnet interface. Once you have set an IP address for your Switch, you 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 you have logged in, the console looks like this:

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 paramet ers.
If a command is entered that is unrecognized by the CLI, the top–level commands will be displayed under the Available

listed in the <portlist> will be affected.
all − Configure all ports on the Switch.
<portlist> − Specifies a port or range of ports to be configured. The port list is specified by
listing the lowest switch number and the beginning port number on that switch, separated
by a colon. Then the highest switch number, and the highest port number of the range
(also separated by a colon) are specified. The beginning and end of the port list range are
separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies
switch number 2, port 4. 1:3–2:4 specifies all of the ports between switch 1, port 3 and
switch 2, port 4 − in numerical order. Non–contiguous portlist entries are separated by a
comma. (ex: 1:1–1:3,1:7–1:9)
medium_type [fiber | copper] – This applies only to the Combo ports. If configuring the
Combo ports this defines the type of transport medium used.
speed – Allows the user to adjust the speed for a port or range of ports. The user has a
choice of the following:
• auto − Enables auto–negotiation for the specified range of ports.
• capability advertised – Configures the capability that advertises to the link partner
to determine the fastest available auto setting.
• [10 | 100 | 1000] − Configures the speed in Mbps for the specified range of ports.
Gigabit ports are statically set to 1000 and cannot be set to slower speeds.
• [half | full] − Configures the specified range of ports as either full–duplex or half–
duplex.
• [master | slave] – The master setting (1000M/Full_M) will allow the port to
advertise capabilities related to duplex, speed and physical layer type. The
master setting will also determine the master and slave relationship between the
two connected physical layers. This relationship is necessary for establishing the
timing control between the two physical layers. The timing control is set on a
master physical layer by a local source. The slave setting (1000M/Full_S) uses
loop timing, where the timing comes form a data stream received from the
master. If one connection is set for 1000M/Full_M, the other side of the
connection must be set for 1000M/Full_S. Any other configuration will result in a
link down status for both ports.
