Introduction
This chapter introduces and shows you how to access the EMS (Element Management
System).
1.1 EMS Overview
The Element Management System (EMS) retrieves management information from switches
using the 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.
Note: Example EMS screens are shown. EMS screens vary depending on your
switch models.
1.1.1 SNMPc Network Manager
SNMPc is network management software produced by Castle Rock.
You must have SNMPc properly installed before you can use the EMS; please refer to the
appendices in this User’s Guide; go to the Castle Rock web site at
