INTRODUCTION
The DGS-3024 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
There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3024:4#. This is
the command line where all commands are input.

DGS-3024 Layer 2 Switch CLI Reference Manual
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.
2
DGS-3024 Layer 2 Switch CLI Reference Manual
Figure 1-3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.53.13.111 with a subnet mask of 255.0.0.0 (8 in CIDR
from). 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-3024 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
• 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:

Figure 2-1. Console Screen after login
Commands are entered at the command prompt, DGS-3024:4#.
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
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.
5
DGS-3024 Layer 2 Switch CLI Reference Manual
Figure 2-3. Example Command Parameter Help
In this case, the command show was entered without a parameter. The CLI will then prompt you to enter the next possible
completions 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 a previously entered command at the command prompt, press the up arrow cursor key. The previous command will
appear at the command prompt.
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.
6
DGS-3024 Layer 2 Switch CLI Reference Manual
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.
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
7
DGS-3024 Layer 2 Switch CLI Reference Manual
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.

NETWORK MANAGEMENT (SNMP) COMMANDS
The network management commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in
the following table.
The DGS-3024 supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The user may specify which
version of the SNMP to use to monitor and control the Switch. The three versions of SNMP vary in the level of security
provided between the management station and the network device. The following table lists the security features of the three
SNMP versions:
SNMP
Version
v1 Community String
v2c Community String
v3 Username
v3 MD5 or SHA
v3 MD5 DES or SHA DES
Authentication Method Description
Community String is used for authentication − NoAuthNoPriv
Community String is used for authentication − NoAuthNoPriv
Username is used for authentication − NoAuthNoPriv
Authentication is based on the HMAC-MD5 or HMAC-SHA algorithms
− AuthNoPriv
Authentication is based on the HMAC-MD5 or HMAC-SHA algorithms
− AuthPriv.
DES 32-bit encryption is added based on the CBC-DES (DES-32)
standard

Purpose Used to create a new SNMP user and adds the user to an SNMP
group that is also created by this command.
Syntax
create snmp user <username 32> <groupname 32> {encrypted
[by_password auth [md5 <auth_password 8-16> | sha
<auth_password 8-20>] priv [none | des <priv_password 8-16>] |

[none | des <priv_key 32-32>]]}
Description
Parameters
The create snmp user command creates a new SNMP user and
adds the user to an SNMP group that is also created by this
command.
<username 32> − An alphanumeric name of up to 32 characters that
will identify the new SNMP user.
<groupname 32> − An alphanumeric name of up to 32 characters

create snmp user
that will identify the SNMP group the new SNMP user will be
associated with.
encrypted – Allows the user to choose a type of authorization for
authentication using SNMP. The user may choose:
auth - The user may also choose the type of authentication
algorithms used to authenticate the snmp user. The choices are:
•
by_password – Requires the SNMP user to enter a
password for authentication and privacy. The password is
defined by specifying the auth_password below. This
method is recommended.
•
by_key – Requires the SNMP user to enter a encryption
key for authentication and privacy. The key is defined by
specifying the key in hex form below. This method is not
recommended.
•
md5 − Specifies that the HMAC-MD5-96 authentication
level will be used. md5 may be utilized by entering one of
the following:
<auth password 8-16> - An alphanumeric sting of
between 8 and 16 characters that will be used to
authorize the agent to receive packets for the host.
<auth_key 32-32> - Enter an alphanumeric sting of
exactly 32 characters, in hex form, to define the key that
will be used to authorize the agent to receive packets for
the host.
•
sha − Specifies that the HMAC-SHA-96 authentication level
will be used.
<auth password 8-20> - An alphanumeric sting of
between 8 and 20 characters that will be used to
authorize the agent to receive packets for the host.
<auth_key 40-40> - An alphanumeric sting of exactly
40 characters, in hex form, to define the key that will be
used to authorize the agent to receive packets for the
host.
priv – Adding the priv (privacy) parameter will allow for encryption in
addition to the authentication algorithm for higher security. The user
may choose:
•
des – Adding this parameter will allow for a 56-bit
encryption to be added using the DES-56 standard using:
<priv_password 8-16> - An alphanumeric string of
between 8 and 16 characters that will be used to
encrypt the contents of messages the host sends to
the agent.
<priv_key 32-32> - An alphanumeric key string of
exactly 32 characters, in hex form, that will be used to
encrypt the contents of messages the host sends to
