49 Carrier-Grade Alarms
This section describes how to view SNMP alarms raised by the device.
49.1 Viewing Active Alarms
The Active Alarms table displays a list of currently active alarms that have been raised by
the device. Once an alarm has been resolved (cleared), the device moves it into the
History Alarms table (see ''Viewing History Alarms'' on page 737). For detailed information
on SNMP alarms, refer to the SNMP Reference Guide document.
To view active alarms:
Open the Active Alarms table (Status & Diagnostics tab > System Status menu >
Carrier-Grade Alarms > Active Alarms). You can also access the table from the
Home page (see ''Viewing the Home Page'' on page
79).
For each alarm, the following information is provided:
Sequential Number: number of the alarm (sequential numbering of each alarm)
Severity: severity level of the alarm:
• Critical (red)
• Major (orange)
• Minor (yellow)
Source: device component from which the alarm was raised
Description: brief explanation of the reason of the alarm
Date: date and time that the alarm was generated
You can view the next 20 alarms (if exist), by clicking the Go to page button.
49.2 Viewing History Alarms
The Alarms History table displays a list of alarms that have been cleared (resolved). You
can configure the maximum number of alarms displayed in the table, using the
AlarmHistoryTableMaxSize ini file parameter. If the maximum is reached and a new alarm
is added to the table, the oldest alarm is removed from the table to accommodate the new
alarm.
To view history alarms:
Open the Alarms History table (Status & Diagnostics tab > System Status menu >
Carrier-Grade Alarms > Alarms History).
