Common notifications

SNMPv1 TRAP with defaults

Send SNMPv1 TRAP through unified SNMPv3 message processing framework using the following options:

  • SNMPv1
  • with community name ‘public’
  • over IPv4/UDP
  • send TRAP notification
  • with Generic Trap #1 (warmStart) and Specific Trap 0
  • with default Uptime
  • with default Agent Address
  • with Enterprise OID 1.3.6.1.4.1.20408.4.1.1.2
  • include managed object information ‘1.3.6.1.2.1.1.1.0’ = ‘my system’
  • use trollius I/O framework

Functionally similar to:

$ snmptrap -v1 -c public demo.snmplabs.com 1.3.6.1.4.1.20408.4.1.1.2 0.0.0.0 1 0 0 1.3.6.1.2.1.1.1.0 s “my system”
