SNMP Management

SNMP

As local area network (LAN) environments became standardized over the

past ten years, multivendor equipment grew with competition. It became

necessary to manage various vendor equipment from a single control con-

sole. Thus, Simple Network Management Protocol (SNMP) emerged as the

standard for managing commercial TCP/IP networks. The term SNMP

broadly refers to the message protocols used to exchange information be-

tween the network management station 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 manage-

ment information base (MIB).

Network Manager

The network manager is a control program that collects, controls, and pre-

sents data pertinent to the operation of the network devices. It resides on a

network management station.

Agent

The agent is a control program that responds to queries and commands from

the network manager and returns requested information or invokes config-

uration changes initiated by the manager. It resides in each network device.

MIB

The MIB is an index to the organized data stored within a network device.

The MIB defines the operating parameters that can be controlled or moni-

tored. When the MIB requests the network manager to retrieve or modify a

particular piece of information about a network device, the network manag-

er transmits that request to the network device. The agent in that device in-

terprets the incoming request, performs the requested task, and sends its

response to the network manager. The network manager collects all of the

data from the various network devices and presents it in a consistent form.
