CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
This chapter introduces the main features and applications of the Switch.
The Switch is a layer-2 standalone Ethernet switch with additional layer-2, layer-
3, and layer-4 features suitable for metro ethernets. The Switch has eight 10/100
Mbps Ethernet ports and two mini-GBIC slots. It also has two GbE dual personality
interfaces with each interface comprising one mini-GBIC slot and one 10/100/
1000 Mbps RJ-45 port, with either port or slot active at a time.
With its built-in web configurator, managing and configuring the Switch is easy. In
addition, the Switch can also be managed via Telnet, any terminal emulator
program on the console port, or third-party SNMP management.
See Chapter 22 on page 165 for a full list of software features available on the
Switch.
This section shows a few examples of using the Switch in various network
environments.
1.1.1 Backbone Application
The Switch is an ideal solution for small networks where rapid growth can be
expected in the near future. The Switch can be used standalone for a group of
heavy traffic users. You can connect computers and servers directly to the
Switch’s port or connect other switches to the Switch.

Chapter 1 Getting to Know Your Switch
MES-2110 User’s Guide
20
In this example, all computers can share high-speed applications on the server. To
expand the network, simply add more networking devices such as switches,
routers, computers, print servers etc.
Figure 1 Backbone Application
1.1.2 Bridging Example
In this example, the Switch connects different company departments (RD and
Sales) to the corporate backbone. It can alleviate bandwidth contention and
eliminate server and network bottlenecks. All users that need high bandwidth can
connect to high-speed department servers via the Switch. You can provide a
super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the
Switch.
Moreover, the Switch eases supervision and maintenance by allowing network
managers to centralize multiple servers at a single location.
