#
# Notification Originator
#
# Send SNMP notification using the following options:
#
# * SNMPv3
# * with local snmpEngineId = 0x8000000001020304 (must configure at Receiver)
# * with user 'usr-sha-aes128', auth: SHA, priv: AES128
# * over IPv4/UDP
# * send TRAP notification
# * with TRAP ID 'authenticationFailure' specified as a MIB symbol
# * do not include any additional managed object information
#
# SNMPv3 TRAPs requires pre-sharing the Notification Originator's
# value of SnmpEngineId with Notification Receiver. To facilitate that
# we will use static (e.g. not autogenerated) version of snmpEngineId.
