Introduction

All network in the world was growing and the management of it was becoming important and very difficult. To solve these problems, the

IETF (Internet Engineering Task Force) created the SNMP(Simple Network Management Protocol).

SNMP enables network administrator to manage any nodes on an IP, get the network performance and help him to solve a great amount of problems.

SNMP Architecture

The network management consist of three basic elements:

Network management stations

Network elements

Agent

Network elements can be nodes or any other monitored device on a network. Network management stations monitor these network elements.

Agents are the management software.

To solve the network management problem, SNMP uses the MIB(Management Information Base) to specify all variables in a network, and

the SMI (Structure of Management Information) to define all specifications for structures and the identifications schemes used to reference it.

All work of SNMP is done at the application layer(layer 7) of the OSI(Open Systems Interconnection) model.
