Introduction

This chapter introduces and shows you how to access the EMS (Element Management System).

1.1 Overview

The Element Management System (EMS) retrieves management information from switches using SNMP protocol.

An EMS is composed of Network Elements (NE) that represent resources in a Network Management System (NMS). The network elements can represent a physical piece of equipment on the network, the components of a device on the network, or parts of the network itself.

The following figure shows a network example.

1.1.1 EMS Components

The EMS consists of two components: the EMS server and the EMS remote client. You must install the EMS server, which provides all the functions to use the EMS. You can install the EMS remote client on other computers if you want to use EMS on them as well.

You can send SNMP messages to managed devices from an EMS remote client (RC) or through the EMS server (S). The following figure shows a network example.
