Table 22 RMON alarm configuration task list
Task Remarks
Configuring a statistics
entry
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.
Configuring an event
entry
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.
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 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
Displaying RMON statistics
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.
Displaying RMON history sampling
information
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.
