11.1.6 Alarm Setup
The alarm setup feature enables operators to customize their alarms either by setting a
preferred severity (overriding the default level of severity) or filtering the alarm.
Slot
Lists all modules with their corresponding slot numbers in brackets
Port
Allows for selection of a particular port, depending on the module selected
under Slot.
Alarm Lists all possible alarms for the selected module in Slot. These alarms are all
registered by each module in the system. If no specific module is selected, all
alarms are listed.
Action
There are five possible options here:
• Set severity: Notify – Overrides the alarm’s default severity to Notify
• Set Severity: Warning – Overrides the alarm’s default severity to
Warning
• Set Severity: Major – Overrides the alarm’s default severity to Major
• Set Severity: Critical – Overrides the alarm’s default severity to Critical
• Filter – Filtering is based on slot, port and alarm type. If an incoming
alarm does not pass the filter, the alarm is discarded. In other words, the
alarm is not visible in the Active Alarms node, not recorded in Alarm
History, and not indicated on the LED of the module itself.
The alarm filter page lists all the relevant alarms for the card type selected (if no specific card is
selected all alarms are listed). When an alarm filter is removed any active alarms which are
filtered will re-appear with the timestamp according to when the filter was removed.
The alarms shown in the alarm drop down list are all alarms registered by each module in the
system. A module is most often represented by a card. When an alarm is raised by the
respective module detecting an error condition it is possible for the module reporting the alarm
to override the alarm description, in order to add some extra information.
In some cases, this may cause the alarm text displayed in the alarm filter not to match the
actual alarm text; but it should be obvious which alarm it is.
The Alarm Filter also applies for the SNMP trap system.
