1.14 Alarm Management Overview

1.14.1 Overview
There are three levels of alarm severity on the system, Critical, Major, and Minor. In general, they are described
as:
Critical - A critical alarm is used to indicate that a severe, service-affecting condition has occurred and that
•
immediate corrective action is imperative.
Major - A major alarm is used to indicate a serious disruption of service or the malfunctioning or failure of
•
important circuits. These troubles require immediate attention and response by the crafts person to
restore or maintain system capability. The urgency is less than critical situations because of lesser immediate
or impending effect on service or system performance.
Minor - Minor alarms are used for troubles that do not have serious effect on service to customers or for
•
troubles that do not affect essential system operation.
Info - Represents an informational message. No explicit action is required of the user.
•
When an anomaly occurs, the system generates management logs. In reality, every time an event occurs on the
system, a log is created. Logs are also generated when performance measurement thresholds have been
exceeded. For an efficient management configuration, users can configure logs to be filtered, output, and shown
on specified devices and formats.

1.14.2 Displaying alarms

Alarms can be displayed using the SHOW ALARMS command. Depending on the parameters used when the
user inputs the SHOW ALARMS command, different information will be provided in the response. For example
the column Time Stamp is added with the time and date of the alarm. This can help the user correlate the alarm
to other problems in the network. The SHOW ALARMS command will be discussed below.
SHOW ALARMS ALL - To display all system alarms, the user inputs this command. The alarm statuses
•
for all system cards will be displayed.
SHOW ALARMS CARD - To display alarms for a specified card
•
SHOW ALARMS PORT - To display alarms for a specified port
•
SHOW ALARMS SEVERITY - To display alarms according to their severity
