DES-3326SR Layer 3 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
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/ANSI terminal and a serial port configured as
above is then connected to the switch’s serial port via an RS-232
DB-9 cable.
You will initially encounter a blank screen; hit Enter twice and
the following screen will appear:
Introduction 9
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
Fig. 1- 1. Initial Console screen.
There is no initial username or password. Just press the Enter
key twice to display the CLI input cursor − DES-3326SR: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 10.1.1.80. You can change the default
Switch IP address to fit 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 by typing
the command reboot.
Fig. 1- 2. Reboot command
Fig. 1- 3. Boot Screen
10 Introduction
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
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 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.
Introduction 11
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
Fig. 1- 4. Assigning the Switch an IP Address
In the above example, the switch was assigned an IP address of
10.52.19.7 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.
12 Introduction
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

USING THE CONSOLE CLI
The DES-3326SR 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.
Switch configuration settings are saved to nonvolatile 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.
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 13
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
• VT-100/ANSI 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:
Fig. 2- 1. Initial Console Screen
Commands are entered at the command prompt, DES-3326SR: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.
14 Using the Console CLI
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
Fig. 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.
Fig. 2- 3. Example Command Parameter Help
In this case, the command config account was entered without
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.
Using the Console CLI 15
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
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.
Fig. 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 toplevel commands will be displayed under the Available commands:
prompt.
16 Using the Console CLI
DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual
Fig. 2- 5. The Next Available Commands Prompt
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.
Fig. 2- 6. Next possible completions: Show Command
Using the Console CLI 17
DES-3326SR Layer 3 Fast Ethernet 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.
