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.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
$ snmpinform -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
$ snmptrap -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2
