DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual

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 Manual. This manual provides a reference for all of the commands contained

in the CLI for members of this series, including the DES-3028, DES-3028P, DES-3028G, DES-3052, and DES-3052P. Examples

present in this manual may refer to any member of this series and may show different port counts, but are universal to this series

of switches, unless otherwise stated. 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

are 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-3028P: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. Users 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.

Boot Procedure V1.00.06

--------------------------------------------------------------------------

Power On Self Test.................................100%

MAC Address : 00-21-91-98-60-77

H/W Version : A1

Please wait, loading V2.00.B23 Runtime image........100%

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, users 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 zrepresents 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.

DES-3028P:4#config ipif System ipaddress 10.73.21.11/255.0.0.0

Command: config ipif System ipaddress 10.73.21.11/8

Success.

DES-3028P:4#

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.90.90.91 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,

SNMP MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Switch CLI Reference Manual

USING THE CONSOLE CLI

The DES-3028/28P/28G/52/52P support 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

Users can also access the same functions over a Telnet interface. Once users have set an IP address for your Switch, users 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 users have logged in, the console looks like this:

Figure 2-1. Initial Console Screen after logging in

Commands are entered at the command prompt, DES-3028P: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

When users enter a command without its required parameters, the CLI will prompt users with Next possible completions:

message.

DES-3028P:4#config account

Command: config account

Next possible completions:

DES-3028P:4#

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 users 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, users 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.

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 username 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.

DES-3028P:4#the

Available commands:

.. ? cable_diag clear

config create debug delete

dir disable download enable

DES-3028P:4#

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 users enter the show command with no additional parameters, the CLI will then display all of the possible next

parameters.
