Advanced Notification Originator

INFORM with custom ContextName

Send SNMP notification using the following options:

  • SNMPv3
  • with user ‘usr-md5-none’, MD5 auth, no priv
  • send INFORM notification
  • in behalf of contextEngineId = SnmpEngineId, contextName ‘my-context’
  • over IPv4/UDP
  • with TRAP ID ‘warmStart’ specified as a string OID

Sending SNMPv3 Notification in behalf of non-default ContextName requires having a collection of Managed Objects registered under the ContextName being used.

Functionally similar to:

$ snmpinform -v3 -l authNoPriv -u usr-md5-none -A authkey1 -n my-context demo.snmplabs.com 12345 0.3.6.1.6.3.1.1.5.2
from pysnmp.hlapi import *

iterator = sendNotification(
    SnmpEngine(),
    UsmUserData('usr-md5-none', 'authkey1'),
    UdpTransportTarget(('demo.snmplabs.com', 162)),
    ContextData(contextName='my-context'),
    'inform',
    NotificationType(ObjectIdentity('1.3.6.1.6.3.1.1.5.2')).loadMibs('SNMPv2-MIB')
)

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

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]))
