TCP/IP SNMP Operational Model, Components and Terminology.

SNMP Terminology Summary
So, to integrate and reiterate all
of this, let's summarize. SNMP consists of a small number of network
management stations (NMSes) that interact with regular TCP/IP devices
that are called managed nodes. The SNMP manager on the NMS and the SNMP
agents on the managed nodes implement the SNMP protocol and allows network
management information to be exchanged. SNMP applications run on the
NMS and provide the interface to the human administrator, and allow
information to be collected from the MIBs at each SNMP agent, as shown
in Figure 270.
Simple! See, the name is good after all. J
Figure 270: SNMP Operational Model This diagram shows a simplified implementation of SNMP, with one network management station used to maintain three managed nodes. Each device has an SNMP Entity, and they communicate using SNMP messages. The SNMP entity of the NMS consists of the SNMP Manager and one or more SNMP Applications; the managed nodes each run an SNMP Agent and maintain a Management Information Base (MIB).
|
 Key Concept: SNMP allows a network administrator using a network management station (NMS) to control a set of managed nodes. Each device incorporates an SNMP entity that implements the technology. In an NMS, the entity consists of an SNMP manager module and a set of SNMP applications; in a managed node, an SNMP agent and management information base (MIB).
