INTRODUCTION
This document is a reference guide for all DES-3010F/DES-3010G/DES-3018/DES-3026 switches. Throughout this manual, the
DES-3026 Switch will be the Switch referred to for all examples and configuration information. All DES-3010F/DES3010G/DES-3018/DES-3026 switches contain the same information and posses the same configuration capabilities. The
difference in switches reside in the port type and the port count only.
The DES-3026 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 − DES-3026:4#. This is
the command line where all commands are input.

DES-30XX 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. The default Switch IP address
can be changed 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
DES-30XX 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 10.53.13.33 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 DES-3026 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, DES-3026:4#.
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
DES-30XX 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
DES-30XX 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
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.

times <value 1-255> - The number of individual ICMP echo
messages to be sent. The maximum value is 255. The default is
0.
timeout <sec 1-99> - Defines the time-out period while waiting for
a response from the remote device. A value of 1 to 99 seconds
can be specified. The default is 1 second.

SWITCH PORT COMMANDS
The switch port commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Command Parameters
config ports config ports [<portlist> | all] {speed [auto | 10_half | 10_full |
100_half | 100_full | {1000_full {[master | slave]}}] | flow_control
[enable | disable] | state [enable | disable] | description [<desc 132> | clear_description]}
show ports {<portlist>} {[description | err_disabled]}
Each command is listed, in detail, in the following sections.
config ports
Purpose Used to configure the Switch’s Ethernet port settings.
Syntax
Description This command allows for the configuration of the Switch’s Ethernet ports.
Parameters
config ports [<portlist> | all] {speed [auto | 10_half | 10_full | 100_half
| 100_full | {1000_full {[master | slave]}}] | flow_control [enable |
disable] | state [enable | disable] | description [<desc 1-32> |
clear_description]}
Only the ports listed in the <portlist> will be affected.
<portlist> − Specifies a port or range of ports to be configured.
all − Configure all ports on the Switch.
speed – Allows the user to set the speed of a port or range of ports, with
the addition of one of the following:
auto − Enables auto-negotiation for the specified range of ports.
[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-
or half-duplex.
[master | slave] – The master and slave parameters refer to connections
running a 1000BASE-T cable for connection between the Switch port and
other device capable of a gigabit connection. The master setting 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 uses loop timing, where the timing comes form
a data stream received from the master. If one connection is set for 1000
master, the other side of the connection must be set for 1000 slave. Any
other configuration will result in a link down status for both ports.
flow_control [enable | disable] – Enable or disable flow control for the
specified ports.
22
Example usage:
To configure the speed of ports 1-3 to be 10 Mbps, full duplex and state enabled:
DES-30XX Layer 2 Switch CLI Reference Manual
config ports
state [enable | disable] − Enables or disables the specified range of ports.
description <desc 32> - Enter an alphanumeric string of no more than 32
characters to describe a selected port interface.
clear_description – Enter this command to clear the port description of the
selected port(s).
Restrictions Only administrator-level users can issue this command.
DES-3026:4#config ports 1-3 speed 10_full state enable
Command: config ports 1-3 speed 10_full state enable

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 DES-3026 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
Authentication is based on the HMAC-MD5 or HMAC-SHA algorithms
