CAUTION:
The configuration on NMS must be consistent with that on the agent. Otherwise, you cannot perform corresponding operations.
SNMPv3 adopts a security mechanism of authentication and privacy. You must configure the username and security level. According to the configured security level, you must also configure the related authentication mode, authentication password, privacy mode, privacy password, and so on.
You must also configure the aging time and retry times. After these configurations, you can configure the device as needed through the NMS. For more information about NMS configuration, see the manual provided for NMS.
Configuration verification
∙After the above configuration, the NMS can establish an SNMP connection with the agent and query and reconfigure values of objects in the agent MIB.
∙If an idle interface on the agent is shut down or brought up, the NMS receives trap information sent by the agent.
