Configuring SNMP Proxy Using User-Defined Parameter Settings

Usage Scenario

As shown in Figure 1, a middle-point device and the cabinet control unit (CCU) of a managed device are placed in an outdoor cabinet. The middle-point device needs to communicate management information between the network management station (NMS) and managed device, so that the NMS can manage the configurations and system software version of the managed device.

If you want to use the NMS to manage the master device and the monitored device in a unified manner, deploy SNMP proxy on the master device. The NMS considers the master device and the monitored device as a virtual management unit, which significantly reduces the number of NEs to be managed by the NMS. This saves network management costs, monitors device running performance in real time, and improves service quality.

If you do not want the middle-point device to communicate with the managed device based on default parameter settings, configure SNMP proxy using user-defined parameter settings. After you configure SNMP proxy, the middle-point device communicates with the managed device based on the user-defined parameter settings.

Pre-configuration Tasks

Before you configure SNMP proxy using user-defined parameter settings, configure a routing protocol, so that the NMS, middle-point device, and managed device can communicate.

Precautions

In this type of SNMP proxy configuration, you must configure SNMP on the managed device.
