3.6.5 SNMP Service
A typical SNMP implementation consists of three factors:
Network management system (NMS)—A combination of hardware (devices) and software
(the SNMP manager) that is used to monitor and administer a network. The SNMP manager
collects information about network connectivity, activity, and events by polling the
managed devices.
Managed device—A managed device (also called a network element) is any device on a
network that is managed by the NMS. Routers and switches are common examples of
managed devices.
SNMP agent—The SNMP agent responds to requests for information and actions from the
manager. The agent also controls access to the agent’s management information base
(MIB), a collection of objects that can be viewed or changed by the SNMP manager. MIB
contains the name, datatype, and the object identifier (OID) which is a numerical address
used to check the status of the components on network devices (like CPU, memory, power
supply, network traffic, etc.).
