Some of our SNMP-enabled devices using SNMPv1 provide a limited subset of options for trap handling.
For instance, you specify an snmp management server for the device to send its traps to, and retry count (up to 4) until it receives trap acknowledgment. In other words, unless we set the retry count to 0 it will resend the same exact trap multiple times because it never receives this "acknowledgment" from the NetXMS server.
It's strange, I read up on this a little and apparently only SNMPv2 or greater is supposed to expect an "acknowledgment" to its informs. Pardon my misunderstanding. But your recommendation for using the external command option in event policy is appreciated. Perhaps this particular device is strange in some way and I might be able to pass some kind of command to net-snmp via event policy action to let the device know the trap was received.
