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 *

iterator = 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'))
    ).loadMibs(
        'SNMPv2-MIB', 'SNMP-COMMUNITY-MIB'
    )
)

errorIndication, errorStatus, errorIndex, varBinds = next(iterator)

if errorIndication:
    print(errorIndication)

from pysnmp.hlapi import *

iterator = sendNotification(
    SnmpEngine(),
    CommunityData('public', mpModel=0),
    UdpTransportTarget(('demo.snmplabs.com', 162)),
    ContextData(),
    'trap',
    NotificationType(

    ).loadMibs(
        'SNMPv2-MIB'
    )
)

errorIndication, errorStatus, errorIndex, varBinds = next(iterator)
