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 Console screen.
There is no initial username or password. Just press the Enter
key twice to display the CLI input cursor −DES-3226L: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 or 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.
DES-3226L Layer 2 Fast Ethernet Switch User’s Guide

The switch is also assigned a unique MAC address by the
factory. This MAC address cannot be changed, and can be found
by entering the “show switch” command into the command line
interface, as shown below.
Figure 1-2. “show switch” command
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.
By default, an IP interface named System is configured on the
switch and contains all of the ports on the switch. The System
interface can be used initially to assign a range of IP addresses
to the switch. Later, when you configure VLANs and IP
interfaces on the switch, the ports you assign to these VLANs
and IP interfaces will be removed from the System interface.
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 DES-3226L:4#
−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. Alternaltively, you can enter DES-3226L:4# −enter
the commands 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.

In the above example, the switch was assigned an IP address of
10.53.13.188 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 DES-3226L 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 non-
volatile 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
