SNMP
Simple Network Management Protocol (SNMP) is a widely used protocol for network management. It facilitates the monitoring and management of network devices, including routers, switches, servers, printers, and other connected hardware. SNMP enables centralized network control by allowing administrators to collect information, configure devices, and detect network issues efficiently..
Simple Network Management Protocol (SNMP) is an application-layer protocol designed to manage network devices and ensure smooth operation within IP networks. SNMP operates primarily over UDP port 161, providing a standardized framework to exchange management information between network devices (agents) and management stations (managers).
SNMP architecture comprises managed devices equipped with SNMP agents, management information bases (MIBs) that organize the data points, and network management systems (NMS) that query or receive notifications. The protocol supports operations such as GET, SET, and TRAP—allowing managers to retrieve or modify device information and receive unsolicited alerts about network events.
Despite evolving through several versions—SNMPv1, SNMPv2, and the more secure SNMPv3—the core functionality remains centered on scalable remote monitoring, diagnostics, status collection, and basic device control, making it foundational for network health and resource management.
