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 TRAP notification
to multiple Managers
with TRAP ID ‘coldStart’ specified as a MIB symbol
include managed object information specified as var-bind objects pair
Functionally similar to:
$ snmptrap -v1 -c public demo.pysnmp.com 1.3.6.1.4.1.20408.4.1.1.2 demo.pysnmp.com 6 432 12345 1.3.6.1.2.1.1.1.0 s “my system”
$ snmptrap -v2c -c public demo.pysnmp.com 123 1.3.6.1.6.3.1.1.5.1

Multiple concurrent notifications#
Send multiple SNMP notifications at once using the following options:

Functionally similar to:
