Overview - Understanding and Configuring SNMP
Simple Network Management Protocol (SNMP) is an application-layer protocol used to manage and monitor network devices and functions. SNMP provides a common language for network devices to relay management information between network elements and monitor the health of network devices such as routers, switches, access points, and even devices such as UPS, printers etc. SNMP is part of the Transmission Control Protocol⁄Internet Protocol (TCP⁄IP) protocol suite and comes bundled with an SNMP agent. The SNMP agents are configured and enabled to communicate with the network management system (NMS).
