About importing MIBs

Use case scenario : As an administrator you want to monitor (listen and classify incoming traps) a device that is not supported by OpenManage Essentials.

Solution: Verify whether the device supports SNMP protocol. If the device supports SNMP protocol, ensure that the service is running and the trap destination points to the OpenManage Essentials-based system. For unsupported device traps, define the traps in OpenManage Essentials by importing the trap definitions using the Alerts portal. The following table provides information about traps before and after they are imported to the OpenManage Essentials database.

Table 1. Importing MIBs. The following table provides information about traps before and after they are imported to the OpenManage Essentials database.
