After getting SNMPv2 traps working from external devices in Check_MK, our users decided they wanted to use SNMPv3. In tcpdump I see the traps coming in to the server’s port 162 and I can send an SNMPv3 trap from the localhost to the localhost and see it in the Event Console’s Recent Event History. But the SNMPv3 traps coming in from external devices don’t show up at all.
Does the Linux server’s snmptrapd play a part in this process? Or is there some extra snmpd config that’s required. Or does anyone know what the problem might be.
Your help would be very appreciated.
