1. How
Network Management Systems
work
● Network management system
● Management program
● SNMP
● MIB
● UPS MIB Data

2. Network Management System
● A Network
Management System
(NMS) is a
combination of
hardware and
software used to
monitor and
administer a network.

3. Management Program
●A management program uses messages
conforming to the simple Network Management
Protocol (SNMP) to poll the agent programs
running in various network devices.

4. SNMP
● When the agents
reply, the SNMP
console program
aggregates the
information and
presents it
graphically.

5. MIB
● The parameters in the managed node are
called management objects. The set of these
management objects is called the Management
Information Base (MIB). The MIB can be
conceptually regarded as a database.

6. UPS MIB data
● Even auxiliary devices such as an UPS
or printer can have a management
agent and a specific MIB.
