+Send crafted TRAP PDU
++++++++++++++++++++++
+
+Initialize TRAP PDU and pass it over to unified SNMPv3 message processing
+framework for further treatment.
+
+* SNMPv2c
+* with community name 'public'
+* over IPv4/UDP
+* send TRAP notification
+* initialize TRAP PDU with the following var-binds:
+  1.3.6.1.2.1.1.3.0 = 123
+  1.3.6.1.6.3.1.1.4.1.0 = 1.3.6.1.6.3.1.1.5.1
+
+Functionally similar to:
+
+| $ snmptrap -v1 -c public 127.0.0.1 1.3.6.1.6.3.1.1.5.1 0.0.0.0 1 0 123
