If the count result overpasses the same threshold multiple times, only the first one can cause an alarm
event. That is, the rising alarm and falling alarm are alternate.
History group
The history group controls the periodic statistical sampling of data, such as bandwidth utilization,
number of errors, and total number of packets.
Note that each value provided by the group is a cumulative sum during a sampling period.
Ethernet statistics group
The statistics group monitors port utilization. It provides statistics about network collisions, CRC
alignment errors, undersize/oversize packets, broadcasts, multicasts, bytes received, packets received,
and so on.
After the creation of a valid event entry on a specified interface, the Ethernet statistics group counts the
number of packets received on the current interface. The result of the statistics is a cumulative sum.
