+Send packet from specific network interface/port
+++++++++++++++++++++++++++++++++++++++++++++++++
+
+Send SNMP notification using the following options:
+
+* SNMPv1
+* with community name 'public'
+* over IPv4/UDP
+* to a Manager at 127.0.0.1 UDP port 162
+* from local address 127.0.0.1, UDP port 61024
+* send TRAP notification
+* with TRAP ID 'coldStart' specified as an OID
+
+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 0
