Simple Network Management Protocol (SNMP) is widely used for IP networks’ devices management and monitoring. Not only routers and switches can be managed using SNMP. It can be used with servers, modems, printers, etc. It is application layer protocol and is defined as IETF standard.
How SNMP works?
It operates based on the following components:
- Network Management Station (NMS), sends SNMP requests to query managed devices and receives alarms send by these devices. NMS uses the MIB to identify and manage device objects.
- Agent – process running on the managed device which is responsible for sending alarms to the NMS and processing requests received from NMS.
- Managed device – a networking device on which the Agent process is running.
