Which version of the "snmptrap" command are you using?
("snmptrap -V")

There was a problem with the default trap port on some versions,
but I thought this had been fixed on all current releases.

Port 161 is the standard port for SNMP *requests* (GET, GETNEXT, SET).
Port 162 is the standard port for SNMP *notifications* (TRAP, INFORM)
