Introduction

The DGS-3308 offers an embedded Web-based (HTML) interface allowing users to manage the Switch from anywhere on
the network through a standard browser such as Netscape Navigator/Communicator or Microsoft Internet Explorer. The
Web 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 ways 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.
Note: This Web-based Management Module does not accept Chinese language input (or other languages
requiring 2 bytes per character).
Where there is a difference in the setup of the Switch between its two operational modes ( L ayer 2 Only and IP
Routing), the sections are divided to correspond with the switch operating mode that is applicable.
Note: IP Routing mode switch configuration settings that are saved NV-RAM using Save Changes
from the Main Menu are retained in the switch's memory when the operational mode is
changed. IP Routing mode settings are simply inactive when the switch is in Layer 2 Only
mode.

Before You Start

The DGS-3308 Gigabit Ethernet Layer 3 Switch supports a wide array of functions and gives great flexibility and increased
network performance by eliminating the routing bottleneck between the WAN or Internet and the Intranet. Its function in a
network can be thought of as a new generation of router that performs routing functions in hardware, rather than software.
It is a router that also has up to eight independent Gigabit Ethernet collision domains – each of which can be assigned an
IP subnet.
This flexibility and rich feature set requires a bit of thought to arrive at a deployment strategy that will maximize the
potential of the Switch.

General Deployment Strategy

1. Determine how the network would be best segmented. This is probably done using VLANs in an existing layer 2
switched network.
2. Develop an IP addressing scheme. This involves allocating a block of IP addresses to each network segment. Each
network subnet is then assigned a network address and a subnet mask. See Chapter 5, "Switch Management
and Operating Concepts," in the section titled IP Addressing and Subnetting for more information.
