Table 23 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.
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 24 Displaying RMON running status
Task Remarks
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 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
view 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.
