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:
z
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.
z
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.
SNMP Mechanism
An SNMP enabled network comprises network management station (NMS) and Agent.
z
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.
z
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.
