A ppendix A Understanding SNMP

As local area network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with compe- tition. It became necessary to manage the various vendor equip- ment from a single control console. Thus, the SNMP emerged as the standard for managing commercial TCP/IP networks.

The term SNMP broadly refers to the message protocols used to exchange information between the network and the managed devices, as well as to the structure of network management data- bases.

SNMP BASIC COMPONENTS

SNMP has three basic components: Network Manager, Agent, and MIB.

Network Manager

This is a control program that collects, controls, and presents data pertinent to the operation of the network devices. It resides on a network management station.

Agent

This is a control program that responds to queries and commands from the network manager and returns requested information or invokes configuration changes initiated by the manager. It resides in each network device.
