Re: Dampening

You can do that and play with the timers, as well as set the 'max suppress'
timer to 30. Due to the nature of the 1/2 life timer, the penalty begins to
decay immediately. This makes it kind of harder to set the time to be
exactly 30 seconds.

The initial question from Antonio is a bit unclear to me since the first
flap does not suppress the interface ... but I believe it should be how to
make this "reset or unsuppressed 30 seconds from the initial suppress time".

By default, the max suppress time is 20 seconds, so some configs are needed
to make this 30 second goal happen.

I could not get it to be exact ... but using the command line I came close.
Would be interested to hear if you were able to get this to be an exact
thing. I may have overlooked something.
