Chapter 1 Web-based Switch Configuration

Introduction

Login to the Web Manager

Web-based User Interface

Web Pages

Introduction

All software functions of the DES-3200 Series switches can be managed, configured and monitored via the

embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere on the network

through a standard browser. The browser acts as a universal access tool and can communicate directly with the

Switch using the HTTP protocol.

The Web-based management module and the Console program (and Telnet) are different wa ys to access the

same internal switching software and configure it. Thus, all settings encountered in web-based management are

the same as those found in the console program.

Login to the Web Manager

To begin managing the Switch, simply run the browser installed on your computer and point it to the IP address you

have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where

the numbers 123 represent the IP address of the Switch.

NOTE: The factory default IP address is 10.90.90.90.

This opens the management module’s user authentication window, as seen below.

Figure 1-1 Enter Network Password w ind ow

Leave both the User Name field and the Password field blank and click OK. This will open the Web-based user

interface. The Switch management features available in the web-based manager are explained below.

Web-based User Interface

The user interface provides access to various Switch configuration and management windows, allows you to view

performance statistics, and permits you to graphically monitor the system status.

Areas of the User Interface

The figure below shows the user interface. Three distinct areas divide the user interface, as described in the table.

Area 1

Select the menu or window to display. Open folders and click the hyperlinked menu buttons

and subfolders contained within them to display menus. Click the D-Link logo to go to the D-

Link website.

Area 2

Presents a graphical near real-time image of the front panel of the Switch. This area displays

the Switch’s ports, console and management port, showing port activity.

Some management functions, including save, reboot, download and upload are accessible

here.

Area 3

Presents switch information based on user selection and the entry of configuration data.

Web Pages

When connecting to the management mode of the Switch with a web browser, a login screen is displayed. Enter a

user name and password to access the Switch’s management mode.

Below is a list of the main folders available in the Web interface:

System Configuration — In this section the user will be able to configure features regarding the Switch’s

configuration.

Management — In this section the user will be able to configure features regarding the Switch’s management.

L2 Features — In this section the user will be able to configure features regarding the Layer 2 functionality of the

Switch.

L3 Features — In this section the user will be able to configure features regarding the Layer 3 functionality of the

Switch.

QoS — In this section the user will be able to configure features regarding the Quality of Service functionality of the

Switch.

ACL — In this section the user will be able to configure features regarding the Access Control List functionality of the

Switch.

Security — In this section the user will be able to configure features regarding the Switch’s security.

Network Application — In this section the user will be able to configure features regarding network applications

handled by the Switch.

OAM — In this section the user will be able to configure features regarding the Switch’s operations, administration

and maintenance (OAM).

Monitoring — In this section the user will be able to monitor the Switch’s configuration and statistics.

NOTE: Be sure to configure the user name and password in the User Accounts menu before

connecting the Switch to the greater network.

Device Information

This window contains the main settings for all the major functions for the Switch. It appears automatically when you

log on to the Switch. To return to the Device Information window after viewing other windows, click the DES-3200

Series link.

The Device Information window shows the Switch’s MAC Address (assigned by the factory and unchangeable), the

Boot PROM Version, Firmware Version, Hardware Version, and many other important types of information. This is

helpful to keep track of PROM and firmware updates and to obtain the Switch’s MAC address for entry into another

network device’s address table, if necessary. In addition, this window displays the status of functions on the Switch

to quickly assess their current global status.

Many functions are hyper-linked for easy access to enable quick configuration from this window.

This folder contains windows that perform Digital Diagnostic Monitoring (DDM) functions on the Switch. Th ere are

windows that allow the user to view the digital diagnostic monitoring status of SFP modules inserting to the Switch

and to configure alarm settings, warning settings, temperature threshold settings, voltage threshold settings, bias

current threshold settings, Tx power threshold settings, and Rx power threshold settings.

DDM Settings

The window is used to configure the action that will occur for specific ports when an exceeding alarm thre shold or

warning threshold event is encountered.
