Configuring the RMON alarm function
z If you need to configure that the managed device sends a trap to the NMS when it triggers an alarm
event, you should configure the SNMP agent as described in SNMP Configuration before
configuring the RMON alarm function.
z As the alarm variables that can be configured through Web network management are MIB
variables that defined in the history group or the statistics group, you must make sure that the
RMON Ethernet statistics function or the RMON history statistics function is configured on the
monitored Ethernet interface.
Perform the tasks in
Table 1-3 to configure RMON alarm function.
Table 1-3 RMON alarm configuration task list
Task Remarks
Configuring an Event
Entry
Optional
You can create up to 60 event entries for an event table.
An event entry defines event indexes and the actions the system will take,
including log the event, send a trap to the NMS, take no action, and log the
event and send a trap to the NMS.
An entry cannot be created 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.
Configuring an Alarm
Entry
Required
You can create up to 60 alarm entries for an alarm table.
With an alarm entry created, the specified alarm event will be triggered
when an abnormity occurs, and the alarm event defines how to deal with
the abnormity.
An entry cannot be created 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 1-4.
Table 1-4 Display RMON running status
Task Remarks
Displaying RMON Statistics
Information
View 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.
Displaying RMON History
Sampling Information
After you have created 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 view the entries in this table. And the number
of history sampling records that can be displayed and the history
sampling interval are specified when you configure the history
group.
