DES-3226L Layer 2 Fast Ethernet Switch User’s Guide

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.

DES-3226L Layer 2 Fast Ethernet Switch User’s Guide

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:

DES-3226L Layer 2 Fast Ethernet Switch User’s Guide

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.

Figure 1-3. Assigning the Switch an IP Address

DES-3226L Layer 2 Fast Ethernet Switch User’s Guide

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
