SNMP (Simple Network Management Protocol) is a widely used protocol for managing and monitoring network devices. In an SNMP-based network:
Each managed device runs anagent processthat collects and stores management information.
Themanagement process(typically running on a Network Management System, or NMS) communicates with the agent using SNMP messages.
SNMP defines several types of messages, such as GET, SET, and TRAP, which allow the NMS to query or modify device configurations and receive notifications from the agent. Other options like NETCONF, HTTP, and YANG are unrelated to SNMP communication.
