[SNMP4J] Reg: Not able to receive traps with AuthPriv security level

[Nithin Jagadeesh]

Hi Frank,

Thank you for the quick response :)

Yes, EngineId at receiver and sender are same. 
Yes, the authentication/privacy passwords on the receiver site are localized
for the engine ID of the sender. I am passing engineId while creating USM
instance and UsmUser instance at receiver side, I think this is what
localized you meant. 
Please correct me if I misunderstood.

However the engineId validation is passing through successfully with engine
discovery property enabled/disabled.

Thanks & Regards,
Nithin K J

Hi,

Most likely, this is an engine ID problem.
Are the engine IDs unique?
Is the authentication/privacy passwords on the receiver site
localized for the engine ID of the sender?

Best regards,
Frank
