# SNMPv1 TRAP variants

## Custom SNMPv1 TRAP

Send SNMPv1 TRAP through unified SNMPv3 message processing framework.

Original v1 TRAP fields are mapped into dedicated variable-bindings, (see RFC2576) for details.

- SNMPv1

- with community name ‘public’

- over IPv4/UDP

- send TRAP notification

- with Generic Trap #6 (enterpriseSpecific) and Specific Trap 432

- overriding Uptime value with 12345

- overriding Agent Address with ‘127.0.0.1’

- overriding Enterprise OID with 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 demo.snmplabs.com 1.3.6.1.4.1.20408.4.1.1.2 127.0.0.1 6 432 12345 1.3.6.1.2.1.1.1.0 s “my system”

    from pysnmp.hlapi import *

    errorIndication, errorStatus, errorIndex, varBinds = next(
        sendNotification(
            SnmpEngine(),
            CommunityData('public', mpModel=0),
            UdpTransportTarget(('demo.snmplabs.com', 162)),
            ContextData(),
            'trap',
            NotificationType(
                ObjectIdentity('1.3.6.1.4.1.20408.4.1.1.2.0.432'),
            ).addVarBinds(
                ('1.3.6.1.2.1.1.3.0', 12345),
                ('1.3.6.1.6.3.18.1.3.0', '127.0.0.1'),
                ('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'))
            )
        )
    )
    if errorIndication:
        print(errorIndication)
