the oversize and undersize packets received by GigabitEthernet 1/0/1 that are in correct data format
and sample it in every 10 seconds. When the change ratio between samples reaches the rising
threshold of 50, event 1 is triggered; when the change ratio drops under the falling threshold, event 2 is
triggered.
