[SNMP4J] Sending SNMP V3 Traps with or without Agent?

[Frank Fock]

Hi Imene,

(V3) traps can be sent without implementing a command responder SNMP entity (=agent).

Nevertheless, I would recommend to implement an agent, because SNMP favours the trap-directed-polling
pattern, where a trap receiver periodically polls key MIB objects to detect failures or alarm conditions that it
might have missed because of lost traps.

Thus, the traps only reduce the time a certain conditions is detected by the receiver and not that it is detected at all.

Hope this helps.

Best regards,
Frank

Knowing that, This software must discover SNMP devices in order to receive Traps from those devices that appears on its list. But What happen in a case of an Application?
