CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
Your Switch is a stand-alone, layer-2, Ethernet switch with 24 100/1000 Mbps Ethernet ports,
two mini-GBIC (SFP, Small Form-factor Pluggable) slots, and one 10/100 Mbps Ethernet port
for out-of-band management.
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 33 on page 221 for a full list of software features available on the Switch.
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.
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.

Chapter 1 Getting to Know Your Switch
1.1.2 Bridging Example
In this example application 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.
Moreover, the Switch eases supervision and maintenance by allowing network managers to
centralize multiple servers at a single location.
Figure 2 Bridging Application
1.1.3 High Performance Switching Example
The Switch is ideal for connecting two networks that need high bandwidth. In the following
example, use trunking to connect these two networks.
Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not
feasible for most people due to the expense of replacing all existing Ethernet cables and
adapter cards, restructuring your network and complex maintenance. The Switch can provide
the same bandwidth as ATM at much lower cost while still being able to use existing adapters
and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.
