Configuration Procedure

n
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.
Before configuring RMON, configure the SNMP agent as described in the SNMP
Configuration in System Volume.
