Handling the eNodeB Alarms

Page64



A fault alarm is generated when a hardware is faulty or a major function is abnormal. A fault alarm has a higher

severity than an event. Based on the status of the faults, fault alarms can be categorized into active alarms and

cleared alarms.

If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is called a cleared alarm.

If a fault is not cleared, the status of the alarm remains active. This type of alarm is called an active alarm.

This section describes the basic concepts related to fault, event, and engineering alarms

Fault Alarm

Event Alarm

Engineering Alarm

If an NE is being installed, commissioned, upgraded, expanded, or relocated, the NE is in the engineering state.

The following are engineering alarms: alarms reported by physical or logical equipment in the engineering

state; alarms that are generated by the peer equipment but are associated with the alarms reported by the

equipment in the engineering state; cleared alarms corresponding to engineering alarms.

An event notifies users of important information when the system is running properly. Users need not handle

an event when it is generated.


Alarm Severity

The alarm severity indicates the severity of an alarm. Based on the severity, all alarms can

be categorized into four types: critical, major, minor, and warning.

Severity Definition Handling Suggestion

Critical Service-affecting condition. Critical alarms require immediate

attention, and must be cleared immediately. For example, faulty

devices are repaired or unavailable resources are restored.

Alarms must be cleared immediately. Otherwise, the

system may break down.

Major Degradation of service, not a complete loss of service. Major

alarms must be cleared during working hours. For example,

device performance and resource performance improve.

These alarms must be cleared in time. Otherwise, some

important functions cannot be implemented.

Minor Non-service-affecting condition. Minor alarms must be handled

within a certain period to avoid severer problems.

This helps maintenance personnel identify and clear

potential problems in time.

Warning Potential service-affecting condition. Warning alarms must be

cleared as required.

You only need to learn about the operating status of the

system.


Based on network management (NM) standards, alarms are categorized as follows:

Power alarm: related to the power system

Environment alarm: related to environment of the equipment room

Signaling alarm: related to service signaling

Trunk alarm: related to the transport subsystem

Hardware alarm: related to boards

Software alarm: related to software

Running alarm: related to system running

Communication alarm: related to the communication system

Integrity violation alarm: a type of security alarm, which indicates that information may be modified, added, or

removed without permission.

Operation violation alarm: a type of security alarm, which indicates that services are unavailable or unreachable due

to incorrect operations, faults, or other reasons.

Physical violation alarm: a type of security alarm, which indicates that physical resources are unavailable due to

possible attacks.

Security violation alarm: a type of security alarm, which indicates that the security service or security mechanism

detects that the system is experiencing attacks.

Time domain violation alarm: a type of security alarm, which indicates that unexpected events have occurred.

Processing error alarm: related to other exceptions.

NM Alarm Type


Browsing Active Alarms or Events On LMT

Alarms are recorded and stored on NEs. If the M2000 is available, NEs also report alarms to the M2000

server for storage. Alarm collection on the NE side is to collect alarm logs. Alarm information of a single NE

or all NEs managed by the M2000 can be obtained on the M2000.

Collecting Alarm Information on M2000

Step :1 Open the Alarm Query Window

Choose Monitor> Browse Current Alarm on M2000


Step :2 In the displayed Filter window set query condition

Set filter criteria in the Basic Setting dialog box to query alarms

meeting conditions.

Severity: indicates the severity of alarms. Options include critical,

major, minor, and warning. You can select a severity as required.

All options are selected by default.

Status: indicates the alarm status. "Cleared" and "Uncleared"

indicate whether alarms are cleared while "Acknowledged" and

"Unacknowledged" indicate whether alarms are confirmed by the

administrator. All options are selected by default.

Type: indicates the type of alarm information. All options are

selected by default.

Alarm query results can be filtered based on the alarm generation

time and alarm clearance time.

Recent alarms can be queried by minute, hour, or day.

Collecting Alarm Information on M2000 Contd


After setting all parameters, click OK.

In the Alarm Source dialog box, select NEs to be queried, set Select to Custom, click Add and select NE from the

displayed menu, and then select NEs in the displayed dialog box. +



Step 3: Save query results.

In Alarm Information window, right-click an entry and choose Save All Records from the shortcut

menu, and then save the results to an .XLS file. .
