Recommended configuration procedure
Configuring the RMON statistics function
The RMON statistics function can be implemented by either the Ethernet statistics group or the history
group, but the objects of the statistics are different, as follows:
A statistics object of the Ethernet statistics group is a variable defined in the Ethernet statistics table,
and the recorded content is a cumulative sum of the variable from the time the statistics entry is
created to the current time. Perform the tasks in
A statistics object of the history group is the variable defined in the history record table, and the
recorded content is a cumulative sum of the variable in each period. Perform the tasks in
to configure RMON history statistics function.

To send traps to the NMS when an alarm is triggered, configure the SNMP agent as described in

You can create up to 100 statistics entries in a statistics table.
After you create a statistics entry on an interface, the system collects
various traffic statistics on the interface, including network collisions, CRC
alignment errors, undersize/oversize packets, broadcasts, multicasts,
bytes received, and packets received. The statistics are cleared at a
You can create only one statistics entry on one interface.
You can create up to 100 history entries in a history table.
After an entry is created, the system periodically samples the number of
packets received/sent on the current interface. It saves the statistics as an
instance under the leaf node of the etherHistoryEntry table.
When you create an entry, if the value of the specified sampling interval is
identical to that of the existing history entry, the system considers their
configurations are the same and the creation fails.
