Dear all,
I resolved my own problem!
I have turned on debug DebugLevel =7 at etc/netxmsd.conf
and I found that the problem should be at my SNMPv3 sending node.
I used another server to send SNMPv3, and when it match the node's SNMPv3 security context the snmp trap can be received at NetXMS.
Thanks for you guys information!
Vincent
