Understanding 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.
SNMP has three basic components: Network Manager , Agent ,
and MIB .
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.
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.
