Common notifications¶
SNMPv2c TRAP via NOTIFICATION-TYPE¶
Initialize TRAP message contents from variables specified in NOTIFICATION-TYPE SMI macro.
- SNMPv2c
- with community name ‘public’
- over IPv4/UDP
- send TRAP notification
- with TRAP ID ‘coldStart’ specified as a MIB symbol
- include managed object information specified as a MIB symbol
Functionally similar to:
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
sendNotification(SnmpEngine(),
CommunityData('public'),
UdpTransportTarget(('demo.snmplabs.com', 162)),
ContextData(),
'trap',
NotificationType(
ObjectIdentity('SNMPv2-MIB', 'coldStart')
)
)
)
if errorIndication:
print(errorIndication)

INFORM, auth: MD5 privacy: DES¶
Send SNMP INFORM notification using the following options:
- SNMPv3
- with user ‘usr-md5-des’, auth: MD5, priv DES
- over IPv4/UDP
- send INFORM notification
- with TRAP ID ‘warmStart’ specified as a string OID
- include managed object information 1.3.6.1.2.1.1.5.0 = ‘system name’
Functionally similar to:
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
sendNotification(SnmpEngine(),
UsmUserData('usr-md5-des', 'authkey1', 'privkey1'),
UdpTransportTarget(('demo.snmplabs.com', 162)),
ContextData(),
'inform',
NotificationType(
ObjectIdentity('1.3.6.1.6.3.1.1.5.2')
).addVarBinds(
ObjectType(ObjectIdentity('1.3.6.1.2.1.1.5.0'),
'system name')
))
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex)-1][0] or '?'
)
)
else:
for varBind in varBinds:
print(' = '.join([ x.prettyPrint() for x in varBind ]))

SNMPv1 TRAP with defaults¶
Send SNMPv1 TRAP through unified SNMPv3 message processing framework using the following options:
- SNMPv1
- with community name ‘public’
- over IPv4/UDP
- send TRAP notification
- with Generic Trap #1 (warmStart) and Specific Trap 0
- with default Uptime
- with default Agent Address
- with Enterprise OID 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:
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
sendNotification(SnmpEngine(),
CommunityData('public', mpModel=0),
UdpTransportTarget(('demo.snmplabs.com', 162)),
ContextData(),
'trap',
NotificationType(
ObjectIdentity('1.3.6.1.6.3.1.1.5.2')
).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'))
)

- SNMPv2c
- with community name ‘public’
- over IPv4/UDP
- send TRAP notification
- with TRAP ID ‘coldStart’ specified as a MIB symbol
- include managed object information specified as a MIB symbol

SNMPv3 TRAP: auth SHA, privacy: AES128¶
Send SNMP notification using the following options:
- SNMPv3
- with authoritative snmpEngineId = 0x8000000001020304 (USM must be configured at the Receiver accordingly)
- with user ‘usr-sha-aes128’, auth: SHA, priv: AES128
- over IPv4/UDP
- send TRAP notification
- with TRAP ID ‘authenticationFailure’ specified as a MIB symbol
- do not include any additional managed object information
SNMPv3 TRAPs requires pre-sharing the Notification Originator’s value of SnmpEngineId with Notification Receiver. To facilitate that we will use static (e.g. not autogenerated) version of snmpEngineId.
Functionally similar to:
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
sendNotification(SnmpEngine(OctetString(hexValue='8000000001020304')),
UsmUserData('usr-sha-aes128', 'authkey1', 'privkey1',
authProtocol=usmHMACSHAAuthProtocol,
privProtocol=usmAesCfb128Protocol),
UdpTransportTarget(('demo.snmplabs.com', 162)),
ContextData(),
'trap',
NotificationType(
ObjectIdentity('SNMPv2-MIB', 'authenticationFailure')
)
)
)
if errorIndication:
print(errorIndication)
