Receive SNMP v3 trap at NetXMS

[tamws]

Dear all,

I know that we can add SNMPv3 get polling connection to the nodes in each node's Communication > SNMP 

How about does NetXMS support receiving SNMPv3 trap send by each node?
Based on my testing seems only SNMPv2 trap can send to NetXMS, when I use SNMPv3 trap with AES encryption of AES128 or AES256, the NetXMS server seems did not receive any traps at v3 protocol.

I'm using NetXMS 4.3.7

Thanks,
Vincent

Hi,

I believe it is some incorrect configuration. NetXMS is capable of receiving SNMPv3 traps. NetXMS supports only DES or AES128 encryption, if I'm not wrong.

To receive SNMP v3 traps, in node properties SNMP settings should be set to SNMP version 3 and corresponding credentials should be specified.

There's an idea to have these credentials separate, here's the ticket for that: https://track.radensolutions.com/issue/NX-2456

Hi lapaladin and Filipp, thanks for your replies!

I tried to set SNMPv3 that use MD5 for authentication and AES128 for encryption. By Wireshark, I am sure the packet can send to my NetXMS server UDP port 162, however it does not appear in the Logs > SNMP Traps

Is there something else I need to configure also?
I'm using Windows Server version, is there any different?

Can I use any debug to see if NetXMS does received the SNMPv3 packet?

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!
