1.1 SNMP Overview

By far, the Simple Network Management Protocol (SNMP) has gained the most

extensive application in the computer networks. SNMP has been put into use and

widely accepted as an industry standard in practice. It is used for ensuring the

transmission of the management information between any two nodes in the network. In

this way, network administrators can easily retrieve and modify the information on any

node in the network. In the meantime, they can locate faults promptly and implement

troubleshooting, capacity planning and report generating.

SNMP adopts the polling mechanism and provides the most basic function set. It is

most appropriate for small-sized, fast-speed and low-cost environments. SNMP

implementation only requires the connectionless transport layer protocol UDP;

therefore, SNMP is widely supported by many products.

SNMP can be divided into two parts, namely, network management station (NMS) and

An NMS is a workstation running client programs. At present, the commonly used NM

platforms include QuidView, Sun NetManager and IBM NetView.

Agent is server software running on network devices.

An NMS can send GetRequest, GetNextRequest and SetRequest messages to an

agent. Upon receiving a request message from the NMS, the agent will perform Read

or Write operation according to the message type, generate and return a Response

message to the NMS.

An agent will send Trap messages on its own initiative to the NMS to report events

when the device status changes or the device encounters any abnormalities such as

restarting the device.
