What are the Basic Components of SNMP?

An SNMP-managed network consists of three key components: managed devices, agents, and network
management systems (NMS).

Managed devices

Contain an SNMP agent and reside on a managed network.

Collect and store management information and make it available to NMS by using SNMP.

Include routers, access servers, switches, bridges, hubs, hosts, or printers.

Agent—A network-management software module, such as the Cisco IOS software, that resides in
a managed device. An agent has local knowledge of management information and makes that
information available by using SNMP.

Network Management Systems (NMS)—Run applications that monitor and control managed
devices. NMS provide resources required for network management. In the case study, the NMS
applications are:
