This is the time window, in seconds, over which the trap throttling limited by cdx6500SNMPMaxNumOfTraps is applied, with 0 meaning the trap is not throttled at all. An admin sets this window's length based on how quickly a real recurring problem should be allowed to re-alert; a short period re-arms throttling quickly, useful for transient issues, while a long period suppresses repeat alerts for longer, useful for known chronic conditions being actively worked. For example, a throttling period of 300 seconds combined with a max of 3 traps means after 3 alerts fire, no more of that trap type will be sent until the 5-minute window resets.
