SNMP - work Managment Protocol
Introduction
Since it was developed in 1988, the work Managment Protocol has e the de facto standard for work managment. Because it is a
simple solution, requiring little code to implement, vendors can easily build SNMP agents to their products. SNMP is extensible, allowing vendors to easily
work managment functions to their existing products. SNMP also separates the managment architecture from the architecture of the hardware
devices, which broadens the base of multivendor support. Perhaps most important, unlike other so-called standards,SNMP is not a mere paper specification,
but an implementation that is widely available today.

Network Managment Architectures
Network managment system contains two primary elements: a manager and agents. The Manager is the console through which work administrator
work managment functions. Agents are the entities that interface to the actual device being managed. Bridges, Hubs, Routers work servers
are examples of managed devices that contain managed objects. These managed objects might be hardware, configuration parameters, performance
statistics, and so on, that directly relate to the current operation of the device in question. These objects are arranged in what is known as a virtual
information database ,called a managment information base, also called MIB. SNMP allows managers and agents municate for the purpose of
accessing these objects.
The model work managment architecture looks like this:

SNMP - work Managment Protocol
A typical agent usually:
● Implements full SNMP protocol.
● Stores and retrieves managment data as defined
