Table 22 RMON alarm configuration task list
Task | Remarks | |
| Required. | |
| You can create up to 100 statistics entries in a statistics table. | |
| As the alarm variables that can be configured through the Web interface are MIB | |
| variables that defined in the history group or the statistics group, configure the | |
| RMON Ethernet statistics function or the RMON history statistics function on the | |
monitored Ethernet interface. | ||
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 reboot. | |
| IMPORTANT: | |
| You can create only one statistics entry for one interface. | |
| Required. | |
| You can create up to 60 event entries for an event table. | |
| An event entry defines event indexes and the actions the system takes, including | |
log the event, send a trap to the NMS, take no action, and log the event and send | ||
a trap to the NMS. | ||
IMPORTANT: | ||
| ||
| You cannot create an entry if the values of the specified alarm variable, sampling | |
| interval, sampling type, rising threshold and falling threshold are identical to those | |
| of an existing entry in the system. | |
|
| |
| Required. | |
| You can create up to 60 alarm entries for an alarm table. | |
With an alarm entry created, the specified alarm event is triggered when an | ||
abnormity occurs. The alarm event defines how to deal with the abnormity. | ||
| ||
| IMPORTANT: | |
| You cannot create an entry if the values of the specified event description, owners, | |
| and actions are identical to those of an existing entry in the system. |
Displaying RMON running status
After you configure the RMON statistics function or the alarm function, you can view RMON running status and verify the configuration by performing tasks in Table 23.
Table 23 Displaying RMON running status
Task | Remarks |
| Display the interface statistics during the period from the time the |
statistics entry is created to the time the page is displayed. The statistics | |
| are cleared after the device reboots. |
|
|
| After you create a history control entry on an interface, the system |
| calculates the information of the interface periodically and saves the |
information to the etherHistoryEntry table. You can perform this task to | |
display the entries in this table. When you configure the history group, | |
| the system specifies the number of history sampling records that can be |
| displayed and the history sampling interval. |
