Answer

The IP address of the device sending the trap must be in the Adapter Platform server, and must be hosted by (with a HostedBy relationship) some unified computing system (UCS) for the trap notification to be created.

To check the HostedBy relationship, use your topology browser or use the following dmctl command:

dmctl -s <OI-Server> get IP::IP-<AgentIPAddress>::HostedBy

To use the topology browser, check under IP section, expand it, select your IP and see if that it has a HostedBy relationship.

The UnknownAgent is set to IGNORE by default. To create a trap notification in the Adapter Platform, the value for UnknownAgent must be set to CREATE in the trap configuration definition, else traps will be dropped.
