INTRODUCTION
The DGS-3100 is a member of the D-Link DGS-3100 switch family. The DGS 3100 product range consists of 24
/ 48 -port 10/100/1000Base-T PoE / NonPoE L2 Stackable Management Switches with 4 Combo SFPs.
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:
•9600 bps
•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
The initial username is admin (lower case). Press the Enter key twice to display the CLI input cursor. 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.

DGS-3100 Gigabit Ethernet Switch Manual
Figure 1–2. Boot Screen
The Switch’s MAC address can also be found in the Web management program on the Device Information
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 vlan default 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 and subnet mask which can then
be used to connect a management s d management agent.

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
Your terminal parameters will need to be set to:
•VT-100 compatible
•9600 bps
0 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:
The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running
an ordinary terminal emulator program (for example, the HyperTerminal program included with the Windows
operating system) using an RS-232C serial cable.
•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-10
