Hi,
Today I’ll be explaining the alarms on Huawei Switches, how to identify them and what does a particular type of alarm mean. So, lets start right away:
1. Alarm Message Format Description
a. Format of Alarm Message
The alarm message begins with "#". Below figure shows the output format of an alarm message.
b. Fields
Field | Description |
# | Information type: # indicates the alarm information. |
TimeStamp | It is the time when an alarm message is generated. It is a variable of the date type and expressed in the format Mmm dd yyyy hh:mm:ss. · Mmm indicates a month. It can be Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec. · dd indicates a date of a month. If the value is less than 10, it is expressed as "(blank)date". For example, " 7". · hh:mm:ss indicates the local time. hh ranges from 00 to 23. mm or ss ranges from 00 to 59. · yyyy indicates a year. TimeStamp and HostName are separated by a space. |
HostName | It is the system name of a local host. HostName and ModuleName are separated by a space. |
ModuleName | It specifies the module that generates alarm messages. ModuleName and Severity are separated by a slash (/). |
Severity | Alarm messages are classified into six severity levels. Severity and Brief are separated by a slash (/). |
Brief | It is a phrase that summarizes information. There should be a colon (:) between the Brief field and the Description field. |
Description | It is a string of characters that describe a detailed alarm message. It is output by a module to the information center. It is filled in by a module at each output time. |
2. Alarm Functionality Description
In terms of functionality, alarm messages are classified into the five types described in following manner:
communicationsAlarm
this indicates that a fault occurs in the process associated with the data transfer. For example, an alarm is generated due to the communication failure between the NEs, between the NE and the OS, or between the OSs.
qualityOfServiceAlarm
This indicates that the QoS decreases. For example, an alarm is generated due to congestion, performance decrease, high resource occupancy, or bandwidth shortage.
processingErrorAlarm
This indicates that an error occurs when the software or process handles data. For example, an alarm is generated due to the software error, memory overflow, version mismatch, or abortion of the program.
environmentalAlarm
This indicates that the environment cannot meet the requirements for the equipment to operate normally. For example, an alarm is generated due to improper temperature, humidity, or ventilation.
equipmentAlarm
This indicates that a fault occurs in physical resources, including power supply, fan, processor, clock, and I/O interfaces.
3. Alarm Information Description
In alarm information, two parts are included:
· Alarm message: This indicates the character string that describes the alarm. It is displayed on a device.
· Alarm meaning: This indicates the meaning of the alarm.
