SNMPv1 TRAP with defaults
+++++++++++++++++++++++++

Send SNMPv1 TRAP through unified SNMPv3 message processing framework
using the following options:

* SNMPv1
* with community name 'public'
* over IPv4/UDP
* send TRAP notification
* with Generic Trap #1 (warmStart) and Specific Trap 0
* with default Uptime
* with default Agent Address
* with Enterprise OID 1.3.6.1.4.1.20408.4.1.1.2
* include managed object information '1.3.6.1.2.1.1.1.0' = 'my system'

Functionally similar to:

| $ snmptrap -v1 -c public localhost 1.3.6.1.4.1.20408.4.1.1.2 0.0.0.0 1 0 0 1.3.6.1.2.1.1.1.0 s "my system"
