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, layer3, and layer-4 features suitable for Ethernets. The Switch has twenty-four 10/
100/1000 Mbps Ethernet ports. It also has four GbE dual personality interfaces
with each interface comprising one mini-GBIC slot and one 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 41 on page 329 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.
GS2200-24 User’s Guide
25
Chapter 1 Getting to Know Your 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.
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.

Chapter 1 Getting to Know Your Switch
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.
Figure 3 High Performance Switched Workgroup Application
1.1.4 IEEE 802.1Q VLAN Application Examples
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned
into multiple logical networks. Stations on a logical network belong to one group.
A station can belong to more than one group. With VLAN, a station cannot directly
talk to or hear from stations that are not in the same group(s) unless such traffic
first goes through a router.
For more information on VLANs, refer to Chapter 9 on page 87.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain thus
increase network performance through reduced broadcast traffic. VLAN groups
can be modified at any time by adding, moving or changing ports without any recabling.
GS2200-24 User’s Guide
27
Chapter 1 Getting to Know Your Switch
Shared resources such as a server can be used by all ports in the same VLAN as
the server. In the following figure only ports that need access to the server need
to be part of VLAN 1. Ports can belong to other VLAN groups too.
Figure 4 Shared Server Using VLAN Example
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the
Switch using a (supported) web browser. See Chapter 4 on page 43.
• Command Line Interface. Line commands offer an alternative to the web
configurator and in some cases are necessary to configure advanced features.
See the CLI Reference Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See
Section 32.7.1 on page 276.
• SNMP. The Switch can be monitored by an SNMP manager. See Section 33.9.1
on page 288.
• Cluster Management. Cluster Management allows you to manage multiple
switches through one switch, called the cluster manager. See Chapter 36 on
page 307.
1.3 Good Habits for Managing the Switch
28
Do the following things regularly to make the Switch more secure and to manage
the Switch more effectively.
• Change the password. Use a password that’s not easy to guess and that
consists of different types of characters, such as numbers and letters.
GS2200-24 User’s Guide
Chapter 1 Getting to Know Your Switch
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes
unstable or even crashes. If you forget your password, you will have to reset
the Switch to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the Switch. You
could simply restore your last configuration.
