INTRODUCTION
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 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.
Figure 1-1. Initial CLI screen
1
DGS-3312SR Layer 3 Gigabit Switch
There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3312SR: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.
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-3312SR Layer 3 Gigabit Switch
Figure 1-3. Assigning an IP Address
In the above example, the switch was assigned an IP address of 10.53.13.144/8 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-3312SR 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
• 9600 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:

DGS-3312SR Layer 3 Gigabit Switch
Figure 2-1. Initial Console Screen
Commands are entered at the command prompt, DGS-3312SR:4#.
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
5
DGS-3312SR Layer 3 Gigabit Switch
When you enter a command without its required parameters, the CLI will prompt you with a Next possible completions:
message.
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.
6
DGS-3312SR Layer 3 Gigabit Switch
Figure 2-4. Using the Up Arrow to Re-enter a Command
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 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.
7
DGS-3312SR Layer 3 Gigabit Switch
Figure 2-5. The Next Available Commands Prompt
The top-level commands consist of commands such as 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.
Figure 2-6. Next possible completions: Show Command
8
DGS-3312SR Layer 3 Gigabit Switch
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.
