Introduction 3
Introduction
DGS-3204 Intelligent Ethernet Switch
This guide discusses how to manage the DGS-3204 switch using the D-View
network management system. The DGS-3204 combines conventional Ethernet,
Gigabit Ethernet and switching technologies into one package. This device
features four ultra high-speed 1000BASE-SX Gigabit Ethernet switching ports
supporting.
Additional information about configuring the DGS-3204 Ethernet switch may be
found in the Ethernet switch’s hardware User’s Guide.
Network Management
As networks grow larger, network management becomes more and more of a
necessity. A large network requires a considerable amount of work to keep it
running smoothly, including time and effort spent on user support,
troubleshooting, network planning, and performance monitoring. The intent of a
network management system (NMS) is to make it possible to monitor a widely
spread-out network (possibly spanning many different sites) from a centralized
location.
Network management works by placing a small degree of “intelligence” in the
network elements (routers, switches, hubs, hosts, etc.) to be managed. This
intelligence takes the form of an agent that is capable of collecting statistics and
status information, as well as performing control operations that affect the
operation of the network. The agent responds to commands and requests for
information from the centralized network management system, allowing the
health and performance of the network to be monitored and adjusted.

4Introduction
A network protocol known as the Simple Network Management Protocol
(SNMP) is generally used to communicate between network management
stations and the devices they manage. SNMP was originally developed for
controlling the devices that made up the infrastructure of the Internet, and has
become the primary standard for network management. SNMP commonly runs
“on top of” the TCP/IP Internet Protocol, though other transmission methods are
possible.
Because a network management station can be used to manage a wide range of
devices, network management software is generally divided into two different
parts: a base platform consisting of software common to the management of all
devices; and a set of modules, each of which can communicate with a narrow
range of devices by way of their SNMP-based agents. If a new device type is
added to the network, then a new module (compatible with the particular
platform being used) needs to be added to facilitate its management.
This manual describes the module used on the D-View platform for controlling
DGS-3204 intelligent Gigabit Ethernet switches.

6 Installing the Management Module
Installing the Module Software
Note: Please ensure that the D-View platform program has been installed
on the computer you are using for network management before proceeding.
Take the following steps to install the module on your network management
system:
1. Exit D-View if you are running it.
2. Insert the Setup/Application CD-ROM containing the module into your
CD-ROM drive (E: will be used in this manual although your CD-ROM
drive letter may be different).
3. If you are using Windows 3.1, choose Run… from the Program
Manager’s File menu. Under Windows 95, choose Run… from the
Start menu on the taskbar. When the dialog box appears, type the
pathname of the Install program on the CD-ROM drive
(E:\INSTALL)
4. Click OK. The installation program will start.
5. When the program prompts for your D-View Directory, enter the
pathname of the directory where you installed D-View, and click
Continue.

6. The installation program will install all of the necessary files onto your
system. When it is finished, it will display the following dialog:
Click on the Exit button. The D-View network management system is now ready
to manage DGS-3204 Ethernet switches.
Preparing the Switch for Management
You will need to make sure that your switch is properly set up before you can
use the management module:
♦Ensure that the switch is connected to the same network as the network
management station.
♦Ensure that the switch’s TCP/IP settings are set properly. If the switch is
on the same local network, the network portion of the switch’s IP address
needs to be the same as that of the network management station. If they
are on separate LANs, the TCP/IP gateway (router) field of both the
switch and the router need to be set properly so that information can be
routed properly between the switch and the management station.
For more information about these and other items, consult the DGS-3204
hardware User’s Guide.

Adding your DGS-3204 Switch to the Map
Before you can manage individual DGS-3204 Ethernet switches, you need to
add them to your D-View network map. You can do this either by:
♦Using D-View’s Auto Discover capability to add all new SNMP-
manageable devices to the map.
♦Using the Add-Modify Map Device command to place each switch on the
map.
To use the second method:
1. Press the Add/Modify a device on the map button shown below.
2. Select the DGS-3204 from the icon list at the right of the Add-Modify
Map Device dialog.
