Appendix A Understanding SNMP

ABOUT SNMP

As local area network (LAN) environments became standard- ized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment 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 databases.

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 com- mands from the network manager and returns requested infor- mation or invokes configuration changes initiated by the manager. It resides in each network device.
