SNMP stands for Simple Network Management Protocol. It is a standard protocol used for managing and monitoring network devices such as routers, switches, servers, printers, and other network devices. SNMP allows network administrators to track and control network performance, detect problems or failures, and perform network maintenance. It works by collecting and sending information from network devices to a central management system, where it can be analyzed and used to optimize network performance. SNMP also enables remote access to network devices, enabling administrators to manage networks from anywhere in the world.
