CHAPTER 1

Introduction

1.1 Overview

This chapter introduces the main features and applications of the MES-2110.
The MES-2110 is a layer-2 standalone Ethernet switch with additional layer-2, layer-3, and layer-4 features suitable for metro ethernets. The MES-2110 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 MES-2110 is easy. In addition, the MES-2110 can also be managed via Telnet, any terminal emulator program on the console port, or third-party SNMP management.
See Chapter 25 on page 215 for a full list of software features available on the MES-2110.
This section shows a few examples of using the MES-2110 in various network environments.

1.1.1 Backbone Application

The MES-2110 is an ideal solution for small networks where rapid growth can be expected in the near future. The MES-2110 can be used standalone for a group of heavy traffic users. You can connect computers and servers directly to the MES­2110’s port or connect other switches to the MES-2110.
MES-2110 User’s Guide
19
Chapter 1 Introduction
In this example, all computers can share high-speed applications on the server. T o 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 MES-2110 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 MES-2110. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the MES-2110.
Moreover, the MES-2110 eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location.
Figure 2 Bridging Application

MES-2110 User’s Guide

1.1.3 High Performance Switching Example

The MES-2110 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 MES-2110 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
Chapter 1 Introduction

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 12 on page 97.
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.
MES-2110 User’s Guide
21
Chapter 1 Introduction
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

1.1.5 Metro Ethernet

The MES-2110 is ideal for connecting users to an Ethernet network that spans a metropolitan area.
In the following example, the MES-2110 is one of many switches that connect users in the metropolitan area to the Internet. The metro ethernet is based on a star (or hub-and-spoke) topology, though other topologies, such as ring or mesh, are also possible. The MES-2110 is connected to the backbone and the

1.2 Ways to Manage the MES-2110

Use any of the following methods to manage the MES-2110.
• Web Configurator. This is recommended for everyday management of the MES­2110 using a (supported) web browser. See Chapter 5 on page 51.
• 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.

1.3 Good Habits for Managing the MES-2110

Do the following things regularly to make the MES-2110 more secure and to manage the MES-2110 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.
• 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 y our password, you will hav e to reset the MES-2110 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the MES-2110. You could simply restore your last configuration.

2.1 Installation Scenarios

This chapter shows you how to install and connect the MES-2110.
The MES-2110 can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack­mounted installation.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front
and 3.4 inches (8 cm) at the back of the MES-2110. This is especially important for enclosed rack installations.

2.2 Desktop Installation Procedure

1 Make sure the MES-2110 is clean and dry.
2 Set the MES-2110 on a smooth, level surface strong enough to support the weight
of the MES-2110 and the connected cables. Make sure there is a power outlet nearby.
3 Make sure there is enough clearance around the MES-2110 to allow air circulation
and the attachment of cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
