SNMP (Simple Network Management Protocol) is a tool used to monitor and manage devices on a network. It allows administrators to track the status of devices like routers or servers and make changes to them remotely. SNMP operates by sending messages between a manager (monitoring system) and agents (devices being monitored). It uses versions like SNMPv1, SNMPv2, and SNMPv3, with the latter offering better security features. This protocol relies on a management information base (MIB) to define what can be monitored or controlled on each device.
