Thank you Mohammed for responding.
I don't see the above mentioned trap in Spectrum at least as "Unknown alert" as the trap source IP in the trap is coming as IP.<some number>. I don't see the trap even under respective device or under VNM. Seems, it is just forwarding the trap to 127.0.0.1.
Please see the highlighted text in red color in my first post. Re-posted the trap information below. Highlighted the trap source in two colors (IP-Red and unknown number - Blue) and also the trap destination in Red which is pointing to 127.0.0.1.
09:59:59.043017 IP 10.1.0.1.58499 > Spectrum01.abcd.com.snmptrap: Trap(99) .iso.org.dod.internet.private.59.1.1.2.1 127.0.0.1 enterpriseSpecific s=0 0 .iso.org.dod.internet.private.59.1.1.2.1="This is a test SNMP trap sent from Varonis DatAdvantage."
Is this something that we need to fix at trap source device? Please confirm.
