Automatic acknowledgement
for sending with INFORM. These notifications are only available
with the version 2c of the protocol. This protocol checks that the manager sends the notification
to the transmitter. This process is simple and reliable, no specific configuration is required for
the manager.
Manual acknowledgement
for Traps V1 and Traps V2c. A specific OID
(“alarmPendingAlarmsalarmAck”) is extracted and its variables are sent with the trap. The
manager must then execute a SET command. This method is more complex but is the only one
that can work with the version 1 of the protocol.
The acknowledgment mode (Trap V1, Trap V2c or Inform) is identical for all alarms. See the next section
“Notifications”
for additional settings.
With “SNMPv2c traps” notifications, it not possible to acknowledge traps.
In the same way, traps which do not require acknowledgment cannot be sent with the “Inform SNMPv2c”
format, even when this format is selected. This is the case with the ‘test’ trap as well as with equipment
information traps such as the ‘Equipment On’ trap.
