III. Private alarm group
The private alarm group calculates the sampled values of alarm variables and
compares the result with the defined threshold, thereby realizing a more
comprehensive alarming function.
System handles the prialarm alarm table entry (as defined by the user) in the following
ways:
Periodically samples the prialarm alarm variables defined in the prialarm formula.
Calculates the sampled values based on the prialarm formula.
Compares the result with the defined threshold and generates an appropriate
event.
Note:
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.
IV. 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.
V. 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.
