![]() ![]() ![]() The objects define the attributes of the managed device, including the names, status, access rights, and data types. ![]() An agent can send unsolicited trap messages to notify the SNMP manager that a significant event has occurred on the agent.Ī MIB is a collection of managed objects that is organized hierarchically. It contains MIB objects whose values can be requested or set by the SNMP manager. ![]() Also, it receives notifications from the agents so as to learn the condition of the network.Īn SNMP agent is a process running on the managed device. It can get values of MIB objects from an agent or set values for them. The SNMP manager uses SNMP to monitor and control SNMP agents, providing a friendly management interface for the administrator to manage network devices conveniently. The following basic concepts of SNMP will be introduced: SNMP manager, SNMP agent, MIB (Management Information Base), SNMP entity, SNMP engine, Notification types and SNMP version. By configuring SNMP on the switch, you define the relationship between the manager and the agent. The agent and MIB reside on the managed device, such as the switch, router, host or printer. The SNMP manager is a host that runs NMS applications. With SNMP, network managers can view or modify the information of network devices, and timely troubleshoot according to notifications sent by those devices.Īs the following figure shows, the SNMP system consists of an SNMP manager, an SNMP agent, and a MIB (Management Information Base). It facilitates device management using NMS (Network Management System) applications. SNMP (Simple Network Management Protocol) is a standard network management protocol, widely used on TCP/IP networks. ![]()
