This section describes the definition and objective of SNMP.
The Simple Network Management Protocol (SNMP) is a network management protocol widely used in the TCP/IP network. SNMP is a method of managing network elements through an NMS which runs network management software.
As network services develop, more devices are deployed on existing networks. The devices are not close to the central equipment room where a network administrator works. When faults occur on the remote devices, the network administrator cannot detect, locate or rectify faults immediately because the devices do not report the faults. This affects maintenance efficiency and greatly increases maintenance workload.
To resolve this problem, SNMP came into being. By employing the "network management over networks" mode, SNMP is used to manage network devices in batches. In addition, SNMP enables the unified management of network devices of different types and from different vendors.
