If a secure network has a few devices, such as a campus network or a small enterprise network, SNMPv1 can be deployed for the normal communication between the NMS and managed devices.
After basic SNMPv1 functions are configured, an NMS can perform basic operations on a managed device, and the managed device can send alarms to the NMS.
This section describes how to specify an NMS and manageable MIB objects for SNMP-based communication between the NMS and managed device to improve communication security.
After you enable the SNMP extended error code function, the device can send multiple types of error codes to the NMS to facilitate fault location and rectification.
You can configure the trap function for the device to send traps of specific features to the NMS, which will help you to locate important problems. In addition, you can set trap sending parameters to improve trap sending reliability.
