Application Scenarios for SNMP
Device Management Through SNMP
Figure 1 illustrates an example network on which SNMP may be applied. On this network, the network administrator needs to configure and manage all devices. However, these devices are sparsely-located around the site, making it impossible for the network administrator to configure and manage them all. To make matters worse, these devices are from different vendors and provide different management interfaces, making network management complex. To reduce operation cost and improve work efficiency, the network administrator can use SNMP to remotely manage, configure, and monitor network devices.
To configure SNMP on the network, configure the NMS program on the management end and an agent on each managed device.
SNMP allows:
The NMS to learn managed device status by sending requests to agents and control the devices remotely.
Each agent to report the managed device status and faults to the NMS in real time.
