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.
