INTRODUCTION
The switch can be managed through the switch’s serial port, Telnet, or the Webbased 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 User’s Guide.
Accessing the Switch via the Serial Port
The switch’s serial port’s default settings are as follows:
• 9600 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.
Introduction
Figure 1-1. Initial Console screen.
There is no initial username or password. Just press the Enter key twice to display
the CLI input cursor − DGS-3212SR: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 from the initial boot console screen
– shown below.
1
DGS-3212SR Switch CLI Reference
Figure 1-2. Boot Screen
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.
The switch’s MAC address can also be found from 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 Webbased 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:
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 z represents the corresponding number of subnets in CIDR
notation.
Introduction
Figure 1-3. Assigning the Switch an IP Address
In the above example, the switch was assigned an IP address of 10.42.73.100 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 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 DGS-3212SR 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 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.
• VT-100 compatible
• 9,600 baud
• 8 data bits
• No parity
• One stop bit
• No flow control
You can 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:
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:
Using the Console CLI

Commands are entered at the command prompt, DGS-3212SR:4#.

DGS-3212SR Switch CLI Reference
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
The dir command has the same function as the ? command.
When you enter a command without its required parameters, the CLI will prompt
you with a Next possible completions: message.
Using the Console CLI
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 you 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, you 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-3212SR Switch CLI Reference
Figure 2-4. Using the Up Arrow to Re-enter a Command Figure 2-5. The Next Available Commands Prompt
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 reexecuted.
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.
Using the Console CLI
The top-level commands consist of commands like 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 you enter the show command with no additional parameters, the
CLI will then display all of the possible next parameters.

DGS-3212SR Switch CLI Reference
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.
