Broadcast Storm Control calculates the average
broadcast bandwidth over the previous
20-second interval. The average is based on four
samples taken at 5-second intervals.
■
When the average value exceeds the rising
threshold value, the rising action is triggered.
The action is not triggered again until the aver-
age broadcast bandwidth falls below the falling
threshold level.
