SNMP is a standard protocol specially designed to manage network devices (servers, workstations, routers, switches, and HUBS, etc.), which is an application layer protocol. SNMP enables network administrators to manage network operation, discover and resolve network issues, and planning network development. The network management system is known from the network management system by SNMP receiving cycle message (and event report).
SNMP network management has three main components: manager, proxy, and network management. The NMS system system (NMSS) SNMP manager is a software program, typically installed on a powerful workstation or server. SNMP Manager is just one of the application software on the network management system. It is mainly used to collect and store management information, and access this information via SNMP, NMSS. Management equipment, also known as network units, may be routers, access servers, switches, and bridges, HUBS, hosts, or printers. The SNMP agent is a software module on the network unit. The SNMP proxy has local relevant management information and converts them into SNMP-related compatible formats. NMS runs the application to implement the monitoring manager. In addition, NMS also provides network management with handlers and must store resources. Any network management requires at least one or more NMSS.
