Hi Corey, If you use the same target for each send(..) then you will receive the trap twice at that target, of course.
I am now a bit confused about what you are trying to accomplish. What is your goal? If you send a trap via a TransportMapping it always gets the from address from that interface (depending on the OS in some cases). If you have used 0.0.0.0, then the OS chooses the address. Otherwise, it will be the address of the physical interface (not an alias). Does if you want to control the from address, you have a hard job. I would recommend, not using the from address on the SNMP (application) level. Best regards, Frank Ellis Corey wrote: > Hi Frank, > > So if I understand correctly and from looking at the code.
