Alarm Management in UA5000Alarm Management in UA5000

The UA5000 supports alarm management functions.

Any abnormality in the system may require the report of an

alarm. You can designate to send the alarm to an NMS

workstation or a CLI terminal.

For a CLI terminal, you can control the alarms output to it

on the UA5000.

For an NMS workstation, you can filter the alarms output to

it on the NMS terminal itself

Alarm IDAlarm ID

8Internal Use


The alarm serial number is a long integer. Each alarm has

different serial number. In general, the alarm serial number is

numbered according to the alarm generation sequence.

Therefore, it can be used to locate a specific alarm.

Alarm serial numberAlarm serial number

9Internal Use


The alarm level is used to identify the severity of an alarm, which

can be divided into critical alarm (critical), major alarm (major),

minor alarm (minor) and warning alarm (warning) in the

descending order of the alarm severity.

Alarm levelAlarm level

10Internal Use


The critical alarm refers to global alarms which will damage the normal

equipment operation and should be repaired immediately, such as

power supply circuit fault and loss of clock reference.

The major alarm refers to local board or line alarms which may lead to

abnormal service operation if not handled in time, such as fiber broken

and physical line fault.

The minor alarm refers to generic state fault alarms and event alarms

that describe whether the boards or lines operate normally, such as bit

error in a certain physical line.

The warning alarm refers to state changes and events which will not

exert any influence upon the system performance and user services

and in which the operator is interested. Some warning alarms are the

prompt information on recovery of equipment to normal state.

11Internal Use


According to the alarm class, alarms can be divided into event

alarm, fault alarm and recovery alarm, where the fault alarm

corresponds to the recovery alarm one by one.

Querying Alarm Configuration InformationQuerying Alarm Configuration Information

An alarm has the following attributes: alarm ID, alarm

name, alarm level, default alarm level, alarm class,

alarm type, command line output flag, statistic flag,

number of parameters, 15-minute threshold, 24-hour

threshold, and detailed alarm description.

display alarm configuration

25Internal Use

Setting Alarm Level AlarmSetting Alarm Level Alarm

Each kind of alarm has default alarm level and current

alarm level.

You can use the alarm alarmlevel alarmid level comm

and to set new alarm level or restore the default alarm

level.

26Internal Use

Setting Alarm Level AlarmSetting Alarm Level Alarm

Use the command alarm alarmlevel alarmid default t

o restore the alarm level to default setting.

Use the display alarm configuration command to query

the alarm level to verify the command execution.

27Internal Use

Setting Alarm Output to CLI TerminalSetting Alarm Output to CLI Terminal

Each alarm has an output flag. Whether the alarm will

be output to the command line depends upon this flag,

and the output setting command is operated based

upon this flag.

You can set whether to output alarms to the command

line according to four modes: alarm ID, alarm level,

alarm class and “set all”.

The output flag of the recovery alarm is the same as

that of the fault alarm.

28Internal Use


The basic form of alarm output to command line

setting command is as follows:

(undo) alarm output

undo alarm output command indicates that a certain

alarm will not be output to the command line, and the

alarm output command indicates that a certain alarm will

be output to the command line.

29Internal Use


The specific operations are as follows:

1) Set it according to alarm ID.

(undo) alarm output alarmid id

Since an alarm ID is used to identify one kind of alarm o

nly, you can use the (undo) alarm output alarmid id com

mand to definitely set whether to output a certain kind of

alarm.

2) Set it according to alarm level.

undo alarm output alarmlevel level

You can use the (undo) alarm output alarmlevel level co

mmand to filter the alarms of a certain level that you thin

k are unimportant.

30Internal Use


3) Set it according to alarm type.

(undo) alarm output alarmtype type

You can use the (undo) alarm output alarmtype type com

mand to set alarm output according to the alarm type.

4) Set all.

(undo) alarm output all

After conducting a series of alarm output settings, the us

er possibly cannot remember the alarm output state in th

e system and it is very troublesome to query one by one.

Therefore, the (undo) alarm output all command can be

used to set the output flag of all alarms.

31Internal Use


5) Query the configuration result

You can use the display alarm configuration command to

query whether the alarms are output to the command

line to verify the command execution.

32Internal Use

Setting Alarm StatisticsSetting Alarm Statistics

The alarm statistics refers to the accumulation and

counting of a certain type of alarms generated during

a period of time so that the user can understand the

alarm frequency. The system can send the threshold

alarm to the user according to the possible alarm

threshold and prompt the user to handle in time.

the alarm statistics is based on 15-minute period and

24-hour period.

A certain type of alarm refers to all alarms of the same

type (i.e., alarms with the same alarm ID).

33Internal Use


Each type of alarm has a statistic flag used to indicate

whether the statistics of this type of alarms should be

conducted. By default, statistics of all alarms will not

be conducted. You can set the statistic flag for alarms

about which you are concerned.

Along with statistic flag setting according to the alarm

ID, statistic flags can also be set for alarms of a

certain alarm level, alarms of certain class and all

alarms for the convenience of batch operations.

34Internal Use


1) Set the alarm statistics

(undo) alarm statistics

The alarm statistics indicates that statistics of a certain

type of alarms will be conducted, and undo alarm

statistics indicates no statistics of a certain type of

alarms will be conducted.

35Internal Use


2) Query the command execution result

You can use the display alarm configuration alarmid com

mand to query the alarm statistic flag and verify the com

mand execution.

36Internal Use



If the statistic flag of a certain type of alarms is “Yes” and

the user pays attention to its statistic information, the

system will conduct statistics of this type of alarms

respectively according to different parameters.

Two thresholds can be set for each type of alarm: 15-

minute threshold and 24-hour threshold. If the threshold is

zero, it indicates that the user does not care whether the

statistical information of this alarm exceeds the threshold.

When the threshold is not zero, if the time of statistics

conducted during a certain period of time exceeds this

threshold, the threshold alarm will be generated. The alarm

threshold is zero by default.

37Internal Use

Setting Alarm ThresholdSetting Alarm Threshold

The specific operations are as follows:

1) Set the alarm threshold

Use the alarm threshold command to set the 15-minute

alarm threshold and 24-hour alarm threshold.

The 15-minute alarm threshold should not be greater than

the 24-hour alarm threshold.


Use the display alarm configuration command to query the

alarm threshold to verify the command execution result.

38Internal Use

Querying Alarm StatisticsQuerying Alarm Statistics

For some alarms, the user possibly is concerned about

the generation frequency of this type of alarms during a

certain period of time and will understand the operation

state of the equipment and analyze possible faults

according to the statistics.

At present, the statistical information in four time periods

will be provided: current 15 minutes, current 24 hours,

past 15 minutes and past 24 hours. That is to say, the

system will save statistical information within two days.

39Internal Use

Querying Alarm StatisticsQuerying Alarm Statistics

The system provides the following command for the user

to query the alarm statistical information.

display alarm statistics

40Internal Use

Clearing Alarm StatisticsClearing Alarm Statistics

If the equipment is left unused for a long period of time

or the alarm statistics has been damaged, you can clear

the previous alarm statistical information manually.

The relevant alarm statistics clearing command is as

follows:

clear alarm statistics

After the execution of this command, the system will clear

the alarm statistics and all alarm statistical information will

not exist any more.

41Internal Use

Querying Basic Alarm InformationQuerying Basic Alarm Information

Use the display alarm list command to query the basic

information about all alarm types.

The queried information includes alarm ID, whether the

alarm should be output, whether statistics should be

conducted, alarm name, etc.

You can use the display alarm list all command to query

the alarm name corresponding to each alarm ID of the

system.
