High Watermark If the percentage of CPU usage time is higher than the high-
watermark,the switch stops packet flow to the CPU (allowing it to catch
up with packets already in the buffer) until usage time falls below the
low watermark.
Low Watermark If packet flow has been stopped after exceeding the high watermark,
normal flow will be restored after usaage falls beneath the low
watermark.
Maximum Threshold If the number of packets being processed by the CPU is higher than the
maximum threshold,the switch stops packet flow to the CPU (allowing
