Configuring alarms for Huawei OLT MA5600 series:
Alarm
management includes the following functions: alarm record, alarm setting, and
alarm statistics. These functions help you to maintain the device and ensure
that the device works efficiently.
An
alarm refers to the notification of the system after a fault is detected. After
an alarm is generated, the system broadcasts the alarm to the terminals, mainly
including the NMS and CLI terminals.
Alarms
are classified into fault alarm and recovery alarm. After a fault alarm is
generated at a certain time, the fault alarm lasts until the fault is rectified
to clear the alarm.
You
can modify the alarm settings according to your requirements. The settings are
alarm severity, alarm output mode through the CLI and alarm statistics Huawei switch.
·
You can run the alarm active
clear command
to clear the alarms that are not recovered in the system.
§
Before clearing an alarm, you can run the display alarm
active command
to query the currently active alarms.
§
When an active alarm lasts a long time, you can
run this command to clear the alarm.
·
Run the alarm
alarmlevel command
to configure the alarm severity.
§
Alarm severities are critical, major, minor, and
warning.
§
Parameter default indicates
restoring the alarm severity to the default setting.
§
You can run the display alarm
list command
to query the alarm severity.
§
The system specifies the default (also
recommended) alarm severity for each alarm. Use the default alarm severity
unless otherwise required.
·
Run the alarm
output/undo alarm output command
to set or shield the output of alarms to the CLI terminal.
§
Setting the output mode of alarms does not
affect the generating of alarms. The alarms generated by the system are still
recorded. You can run the display
alarm history command
to query the alarms that are shielded.
§
When the new output mode of an alarm conflicts
with the previous mode, the new output mode takes effect.
§
The output mode of the recovery alarm is the
same as the output mode of the fault alarm. When the output mode of the fault
alarm is set, the system automatically synchronizes the output mode of its
recovery alarm. The reverse is also applicable. That is, when the output mode
of the recovery alarm is set, the system automatically synchronizes the output
mode of its fault alarm.
·
Run the alarm
jitter-proof command
to configure the alarm jitter-proof function and the jitter-proof period.
§
To prevent a fault alarm and its recovery alarm
from being displayed frequently, you can enable the alarm jitter-proof function
to filter alarms in the system.
§
After the alarm jitter-proof function is
enabled, the alarm in the system is not reported to the NMS immediately but is
reported to the NMS after an alarm jitter-proof period.
§
If an alarm is recovered in an alarm
jitter-proof period, the alarm is not reported to the NMS.
§
You can run the display alarm
jitter-proof command
to check whether the alarm jitter-proof function is enabled and whether the
alarm jitter-proof period is set.
§
By default, the alarm jitter-proof function is
disabled. You can determine whether to enable the function according to the
running of the device.
·
Run the alarm-event
statistics period command
to set the alarm statistics collection period.
§
The system collects the occurrence times of
alarms and events according to the set period. To save the statistical result,
run the alarm-event
statistics save command
to save the statistics to the flash memory.
§
You can use the statistical result of alarms and
events to locate a problem in the system.
§
You can run the display alarm
statistics command
to query the alarm statistical record.
·
Run the display
alarm configuration command
to query the alarm configuration according to the alarm ID. The alarm
configuration that you can query includes the alarm ID, alarm name, alarm class,
alarm type, alarm severity, default alarm severity, number of parameters, CLI
output flag, conversion flag, and detailed alarm description.
·
Run the display
alarm statistics command
to query the alarm statistical record.
§
When you need to know the frequency in which one
alarm occurs within a time range, and to know the working conditions of the
device and analyze the fault that may exist, run this command.
§
Currently, you can query the alarm statistics in
the current 15 minutes, current 24 hours, last 15 minutes, and last 24 hours in
the system.
Assume the following configurations: The output
of all the alarms at level warning are
shielded to the CLI terminal, the alarm jitter-proof function is enabled, the
alarm jitter-proof period is set to 15s, the statistical period of the alarms
and events is set to 72 hours, and all the alarms at level major are saved to the flash memory so that
a problem can be located through the alarm statistical record. To perform these
configurations, do as follows:
huawei(config)#undo alarm output alarmlevel warning
huawei(config)#alarm jitter-proof on
huawei(config)#alarm jitter-proof 15
huawei(config)#alarm-event statistics period 72
huawei(config)#alarm alarmlevel 0x0121a001 critical
huawei(config)#alarm alarmlevel 0x02310000 critical
huawei(config)#alarm-event statistics save
