That is a good question. I know udp will work. You'd have to test TCP (and make
sure tcp was enabled in the agent at configure time). I'm also unclear on
whether or not using tcp would create/tear-down a connection for each trap, or
establish the connection once. You'd have to do some testing.

Yeah, I think it's pretty recent.

Since it's just forwarding a standard SNMP trap, the best example would be a
pared-down version of snmptrapd.

You are lost in a twisty maze of little standards, all different.
