The Simple Network Management Protocol (SNMP) is a standard protocol used for managing devices on IP networks. It allows network administrators to monitor and control network devices such as routers, switches, and servers. SNMP operates by using a manager-agent model, where the manager collects data from agents installed on network devices. SNMP facilitates the exchange of management information through a structured format, enabling efficient communication. It uses a set of commands to retrieve and modify device settings, making it easier to maintain network performance and troubleshoot issues. This protocol is widely used in network management systems across various industries.
