Evaluating NOTIFICATION-TYPE
****************************


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 'linkUp' specified as a MIB symbol

* include values for managed objects implicitly added to
  notification (via NOTIFICATION-TYPE->OBJECTS)

Functionally similar to:

   $ snmptrap -v2c -c public demo.snmplabs.com 0 1.3.6.1.6.3.1.1.5.1 1.3.6.1.2.1.2.2.1.1.123 i 123 1.3.6.1.2.1.2.2.1.7.123 i 1 1.3.6.1.2.1.2.2.1.8.123 i 1

   from pysnmp.hlapi import *

   errorIndication, errorStatus, errorIndex, varBinds = next(
       sendNotification(
           SnmpEngine(),
           CommunityData('public'),
           UdpTransportTarget(('demo.snmplabs.com', 162)),
           ContextData(),
           'trap',
           NotificationType(
               ObjectIdentity('IF-MIB', 'linkUp'),
                              instanceIndex=(123,),
                              objects={('IF-MIB', 'ifIndex'): 123,
                                       ('IF-MIB', 'ifAdminStatus'): 'up',
                                       ('IF-MIB', 'ifOperStatus'): 'up'}
           )
       )
   )

   if errorIndication:
       print(errorIndication)

Sending additional var-binds
============================

Send SNMP notification using the following options:

* SNMPv2c

* with community name 'public'

* over IPv4/UDP

* send INFORM notification

* with TRAP ID 'coldStart' specified as a MIB symbol

* include managed object information specified as a MIB symbol

Functionally similar to:

   $ snmpinform -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.1 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'),
           UdpTransportTarget(('demo.snmplabs.com', 162)),
           ContextData(),
           'inform',
           NotificationType(
               ObjectIdentity('SNMPv2-MIB', 'coldStart')
           ).addVarBinds(
               ObjectType(ObjectIdentity('SNMPv2-MIB', 'sysName', 0), 'my system')
           )
       )
   )

   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]))
