EHS debounce (also called dampening) is the ability to trigger an action (for example an EHS script), if an event happens (N) times within a specific time window (S).
N = [2..15]
S = [1..604800]
Triggering occurs with the Nth event not at the end of S.
There is no sliding window (for example a trigger at Nth event, N+1 event, and so on), as N is reset after a trigger and count is restarted.
When EHS debouncing or dampening is used, the varbinds passed in to an EHS script at script triggering time are from the Nth event occurrence (the Nth triggering event).
If S is not specified, the SR OS continues to trigger every Nth event.
For example:
When linkDown occurs N times in S seconds, an EHS script is triggered to shut down the port.
