To know whether potential problems that affect the carry data services and that are not accompanied by alarms, exist in the network, view the performance data. Then, take the necessary steps to avoid these problems.
RMON is used to monitor and evaluate the communication quality of the ports that carry data services. It is one network management standard that is widely applied. RMON contains Statistics Group, History Group, History Control Group, and Alarm Group.
RMON Type |
Description |
|---|---|
Statistics Group |
Statistics group information indicates the statistic value of every monitoring port on the equipment. It collects statistics on the accumulated or incremental information after the statistics group is created. You can use the function of RMON statistics and management to monitor the using status of the port and collect statistics on the faults occurs when the port is used. |
History Group |
After the RMON historical group is configured, the port periodically collects the network statistics information. The statistics information is temporarily saved for easy handling. You can view the historical groups to read the statistics information. NOTE:
For RMON performance, 15 historical groups can be queried by default. The quantity can be changed to a number ranging from 1 to 15. |
History Control Group |
You can set the historical control group to modify the method that the port obtains the statistics information of historical groups. |
Alarm Group |
You can set the alarm group to monitor the specified alarm variables such as port statistics data. When the value of the monitored data is beyond the defined threshold, an alarm occurs. You can handle the alarm based on the alarm definition. |
