the oversize and undersize packets received by Ethernet 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.
