Appendix A Understanding SNMP

As local area network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a sin- gle control console. Thus, the SNMP emerged as the standard for man- aging commercial TCP/IP networks.

The term SNMP broadly refers to the message protocols used to ex- change 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 perti- nent 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 net- work device.
