- send TRAP notification

- with Generic Trap #1 (warmStart) and Specific Trap 0

$ snmptrap -v1 -c public demo.snmplabs.com 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”

    from pysnmp.hlapi.asyncore import *

    snmpEngine = SnmpEngine()

    sendNotification(
        snmpEngine,
        CommunityData('public', mpModel=0),
        UdpTransportTarget(('demo.snmplabs.com', 162)),
        ContextData(),
        'trap',
        NotificationType(
            ObjectIdentity('1.3.6.1.6.3.1.1.5.2')
        ).addVarBinds(
            ('1.3.6.1.6.3.1.1.4.3.0', '1.3.6.1.4.1.20408.4.1.1.2'),
            ('1.3.6.1.2.1.1.1.0', OctetString('my system'))
        )
    )

    snmpEngine.transportDispatcher.runDispatcher()
