Advanced Notification Originator#
Multiple concurrent notifications#
Send multiple SNMP notifications at once using the following options:
SNMPv2c
with community name ‘public’
over IPv4/UDP
send INFORM notification
to multiple Managers
with TRAP ID ‘coldStart’ specified as a MIB symbol
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
