1.1 SNMP Overview
Simple Network Management Protocol (SNMP) offers a framework to monitor network
devices through TCP/IP protocol suite. It provides a set of basic operations in
monitoring and maintaining the Internet and has the following characteristics:
Automatic network management: SNMP enables network administrators to search
and modify information, find and diagnose network problems, plan for network
growth, and generate reports on network nodes.
SNMP shields the physical differences between various devices and thus realizes
automatic management of products from different manufacturers. Offering only
the basic set of functions, SNMP makes the management tasks independent of
both the physical features of the managed devices and the underlying networking
technology. Thus, SNMP achieves effective management of devices from different
manufacturers, especially in small, high-speed and low cost network
environments.

1.1.1 SNMP Mechanism

An SNMP enabled network comprises network management station (NMS) and Agent.
NMS is a station that runs the SNMP client software. It offers a user friendly
interface, making it easier for network administrators to perform most network
management tasks. Currently, the most commonly used NMSs include Quidview,
Sun NetManager, and IBM NetView.
Agent is a program on the device. It receives and handles requests sent from the
NMS. Only under certain circumstances, such as interface state change, will the
Agent inform the NMS.
NMS manages an SNMP enabled network, whereas Agent is the managed
network device. They exchange management information through the SNMP
protocol.
