.. _alarm-messages-overview:

Alarm messages are numerically coded by the type of alarm.

For more information, see
:ref:`Fault Management Overview <fault-management-overview>`.

In the alarm description tables, the severity of the alarms is represented by
one or more letters, as follows:

.. _alarm-messages-overview-ul-jsd-jkg-vp:

-   C: Critical

-   M: Major

-   m: Minor

-   W: Warning

A slash-separated list of letters is used when the alarm can be triggered with
one of several severity levels.

An asterisk (\*) indicates the management-affecting severity, if any. A
management-affecting alarm is one that cannot be ignored at the indicated
severity level or higher by using relaxed alarm rules during an orchestrated
patch or upgrade operation.

.. note::
    **Degrade Affecting Severity: Critical** indicates a node will be
    degraded if the alarm reaches a Critical level.
