I'm having a strange problem where my snmptrapd server will not accept v2 traps/informs if they are sent via ipv6. My snmptrapd server is version 5.7.2.1 running on Linux. The traps/informs are being sent by version 5.5.1 of snmptrap, also on Linux. I tried version 5.7.2.1 of snmptrap but that did not work either.
Here are the scenarios: 1) v3 inform sent via ipv4 - works 1) v3 inform sent via ipv6 - works 2) change to v2 and send to same ipv6 address - fails. Because I'm running snmptrapd with the '-d' arg I do see the packet come in, but it is not accepted. In the packet dump I can see the correct v2 community name is being used. Of course I switched to a different, appropriate v2 config file for snmptrapd when I switched from sending v3 to v2 traps. 3) keep the same v2 credentials and send via ipv4 - works I couldn't find anything in the bug database that mentions this. Are there any debugging steps that I can do to help figure out what is happening? Here's an example of ipv4 working but ipv6 not when v2 is used.
