SNMPv3 traps are not processed

[Marco-Total]

I am facing the problem that SNMPv3 traps are not processed.

I have created a new SNMPv3 user in my UPS system (Auth = AES, Priv = SHA) and created on the icinga2 server a new user with the same credentials in the /etc/snmp/snmptrapd.conf file:

traphandle default /usr/bin/php /usr/share/icingaweb2/modules/trapdirector/bin/trap_in.php
...
createUser -e 0x80000001020304 icingatrapusv SHA XXX AES XXX
authUser log,execute,net icingatrapusv

After restarting the snmptrap service, I sent a test trap. This trap also arrives at the server, but it is not processed by the trapdirector.

[root@thillmmon1 plugins]# tcpdump -n port 162
dropped privs to tcpdump

But in the trapdirector Log (set to log everything) I don't see any action. I have no problem with SNMPv2 Traps.

Any ideas to solve this problem?

Thx!

I am experiencing the same errors
snmp v3 traps are not shown in the webgui.
Should one create one snmpv3-user for each device that wants to send v3-traps or is one for all sufficient (like for community strings)?
