–
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.
l
Set or shield the output of alarms.
Run the
(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.
l
Set alarm statistics period.
Run the
alarm-event statistics period
command to set the alarm statistics collection
period.
–
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.
l
Filter alarms reporting to NMS.
Run the
trap filter alarm condition
command to filter alarms that the device reports to
the NMS through traps.
The filtering criteria can be alarm ID, alarm severity, alarm type, subrack ID, subrack ID/
slot ID, subrack ID/slot ID/port ID, VLAN interface, and NE.
To reduce alarms and avoid alarm storms, the system does not send alarms of some ONTs
to the NMS. To query the filtering criteria of alarms and events in the system, run the
display trap filter
command.
l
Query alarm configuration and alarm statistics.
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 level, default alarm level, 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 period and previous period
in the system.
l
(Optional) Configure alarm policy for ONT.
In FTTH scenarios, you can configure the ONT alarm policy profile to configure alarms
for different service policies.
1.
Create an ONT alarm policy profile.
