a.Rising and falling alarm events

Event group

The event group defines event indexes and controls the generation and notifications of the events triggered by the alarms defined in the alarm group and the private alarm group. The events can be handled in one of the following ways:

∙Log—Logging event related information (the occurred events, contents of the event, and so on) in the event log table of the RMON MIB of the device, so the management device can check the logs through the SNMP Get operation.

∙Trap—Sending a trap to notify the occurrence of this event to the network management station (NMS).

∙Log-Trap—Logging event information in the event log table and sending a trap to the NMS.

∙None—No action.

Configuring the RMON statistics function

RMON statistics function can be implemented by either the Ethernet statistics group or the history group, but the objects of the statistics are different, and you can configure a statistics group or a history group accordingly.

∙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 1 to configure RMON Ethernet statistics function.

∙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 2 to configure RMON history statistics function.
