Principle Of Re-Transmissions / Acknowledgements Functioning; Events Leading To Sending Of Snmp Notification - Worldcast Systems RELIO User Manual

Relio 4.2.x User Manual – 07/2015

3.25.1. Principle of re-transmissions / acknowledgements functioning

As long as its acknowledgement has not been received, the notification will be re-transmitted at a rate of one
sending every <d> seconds, a maximum of <n> times; where <d> and <n> are the fields respectively <Ack Timeout>
(1) and <Max Retries> (2).
If acknowledgement does not arrive following <n> attempts, the notification is "frozen", that-is-to-say, it is put on
standby until a new notification of the same type occurs. It can also be manually "unfrozen" using the "Replay
Traps" button (3).
It is important to note that non transmitted notifications are not lost. They are kept to be re-transmitted when
conditions permit it once again. When a new notification occurs the "frozen" notification is re-activated, and a
cycle of sending attempts starts up again.
