SNMP

UNDERSTANDING SNMP

The Simple Network Management Protocol (SNMP) is the de facto

standard for managing commercial Transmission Control Proto-

col/Internet Protocol (TCP/IP) networks. It allows vendor equip-

ment to be managed from a single control console.

The term SNMP broadly refers to the message protocols used to

exchange information between the network and the managed de-

vices, as well as to the structure of network management databas-

es.

SNMP Components:

SNMP has three basic components: Network Manager, Agent,

and MIB.

Network Manager

• A control program that collects, controls, and presents data

pertinent to the operation of the network devices.

• Resides on a network management station.

Agent

• A control program that responds to queries and commands

from the network manager.

• Returns requested information or invokes configuration

changes initiated by the manager.

• Resides in each network device connected.
