EHS debounce is the ability to trigger an action (for example, an EHS script), if an event happens (N) times within a specific time period (window) in seconds (S):
where:
N = 2 to 15 occurrences
S = 1 to 604800 seconds
For example, if linkDown occurs N times in S seconds, an EHS script is triggered to shut down the port.
Triggering happens with the Nth event, not at the end of the time window (S).
There is no sliding time window (for example, a trigger at the Nth event, N+1 event, and N+2 event) because N is reset after a trigger and the count is restarted.
When EHS debouncing is used, the varbinds passed in to an EHS script at script triggering time are from the Nth event occurrence (the Nth triggering event); see Variable Passing.
If S is not specified, the 7705 SAR continues to trigger every Nth event.
