Advanced Notification Originator#
Multiple concurrent notifications#
Send multiple SNMP notifications at once using the following options:
SNMPv2c and SNMPv3
with community name ‘public’
over IPv4/UDP
send INFORM notification
to multiple Managers
with TRAP ID ‘coldStart’ specified as a MIB symbol
include managed object information specified as var-bind objects pair
Here we tag each SNMP-COMMUNITY-MIB::snmpCommunityTable row with the same tag as SNMP-TARGET-MIB::snmpTargetAddrTable row what leads to excessive tables information.
Functionally similar to:
$ snmptrap -v2c -c public demo.pysnmp.com 12345 1.3.6.1.6.3.1.1.5.2
$ snmpinform -v2c -c public demo.pysnmp.com 12345 1.3.6.1.6.3.1.1.5.2
import asyncio
from pysnmp.hlapi.asyncio import *
async def sendone(snmpEngine, hostname, notifyType):
errorIndication, errorStatus, errorIndex, varBinds = await sendNotification(
snmpEngine,
CommunityData("public", tag=hostname),
UdpTransportTarget((hostname, 162), tagList=hostname),
ContextData(),
notifyType,

"{}: at {}".format(
