We are receiving SNMPv2 traps from devices where the source ip is an IPv6 address and the agent varbind is an IPv4 address.
Spectrum is not using the agent varbind to determine the source of the trap as expected. It is using the IPv6 from the source.
This is causing Spectrum to generate an unknown trap event on the VNM model.
Release : 22.2.5 and below
A review of the code shows that if the received trap source address is an IPv6, always consider it as srcAddr and ignore the agent address which was set in the trap PDU.
This is functioning as coded.
An enhancement is planned for Spectrum 22.2.7 to address this issue. No release date set for Spectrum 22.2.7 at the time this knowledge document was published.
