Overview of SNMP

SNMP is a UDP-based network protocol that facilitates the exchange of management
information between network devices. An SNMP-managed network consists of three key
components: managed devices, agents, and network management systems (NMS).
A managed device is a network node that contains an SNMP agent and that resides on a
managed network. Managed devices exchange management information with NMSs via
their local agent.
An agent is a network management software module that resides on a managed device. An
agent maintains a collection of management information that it provides in an SNMP-
compatible format upon request to NMSs.
An NMS executes applications that monitor and control managed devices.
