Traps not Show in Alerts&Activity (Updated Content)

Question

Hi there,

I tried to setup trap viewer in solarwinds server. Before I followed the solarwind snmp service installation video on windows server, trap already works by checking each node summary on orion console(unless polling is not ran by snmp), but when I clicked alerts&activity -> traps, I don't see any info. After I configured the snmp service, I cannot sync all the traps to the viewer. I only receive one node which was already in trap viewer before configuration. I'm using SNMPv2, and NCM 7.9 & NPM 12.4. I realized that at the bottom left corner of trap viewer indicates solariwinds on a sql server. Does it mean SQL server not setting up right? Or firewall? BTW, I have no problem to receive all syslogs from all nodes on syslog viewer, no problem to test community string credential under node property by using UDP port 161 (not 162, weird). Thank you!!

mesverrum​ Thank you for the answer, it does make sense. I opened a ticket with solarwinds support in the meantime. I will post the final answer here.

Traps are outbound messages from the node to a trap server, that normally always happens on port 162.  This is really totally unrelated to the snmp requests that happen on port 161.  Its more similar to syslog messages on port 514.  You shouldn't have anything to do with radius also, traps are not authenticated anywhere.  They contain a community string but even that is informational only and are mostly just used to sort message sources on the receiving system.  There is no setup in solarwinds that you need to do for traps, if the device sends a trap to the Orion server and it doesn't get blocked along the way it will just show up in orion.
