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 Displaying RMON running status
Task
Displaying RMON statistics
Displaying RMON history sampling
information
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, you must make
sure that the RMON Ethernet statistics function or the RMON history statistics
function is configured on the monitored Ethernet interface.
After a statistics entry is created 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:
Only one statistics entry can be created 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 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.
IMPORTANT:
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.
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.
IMPORTANT:
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.
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.
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.
