Using alarms to collect and monitor device status
Management and interface modules
When a management module or interface module is removed from the chassis, a major level alarm is generated in the alarm history log. If
the management module, interface module, or SFM is powered off, a critical level alarm is generated in the alarm history log.
When a module is removed or powered off, alarms for all subsystems of the module are cleared from the current alarm log. If a module is
removed from the chassis, all alarms are cleared from the current alarm log, and memory associated to its subsystems is freed. When a
module is added to the configuration, memory is reallocated.
Temperature
If temperature on the management module or interface module increases to the highest threshold, a major alarm is set. If temperature
decreases below the highest threshold, the alarm is cleared from the current alarm log, and an additional alarm is sent to the alarm history
log stating that the condition has been removed. If the temperature increases into shutdown range, a critical level alarm is reported and
logged in the alarm logs.
Optics
Alarms and warnings are monitored only for optic devices that support optical monitoring. If optical monitoring is disabled, then no alarms
are generated.
If an optic is removed or not present, a major alarm is reported and logged and any existing alarms are cleared from the current alarm log.
To display all alarms in the alarm log related to a
specific interface module
(where n, module number is 1-3 for MLX/XMR
and 1 for CER/CES)
and all alarms for it’s subsystems.
show alarm [history] lp n all
To display all alarms in the alarm log related to
subsystem information for an interface module
(where n, module number is 1-3 for MLX/XMR
and 1 for CER/CES)
and either all events on a specific subsystem, or
events for a particular subsystem
(where subsystem is temperature or optic)
(where x, is a the device number).

To display all alarms in the alarm log for all SFM and
subsystems for the SFM.
show alarm [history] sfm all
To display all alarms in the alarm log related to a
specific SFM
(where n, is SFM slot 1-8 for MLX/XMR)
and all alarms for it’s subsystems.
show alarm [history] sfm n all
To display all alarms in the alarm log related to
SFM information for a specific SFM
(where n, is SFM slot 1-8 for MLX/XMR)
and either all events on a specific subsystem, or
events for a particular subsystem
(where subsystem is temperature or
fabric-element)
(where x is 1-4 for a fabric element device
number).
