| Description | This object specifies those alarms currently being asserted
by the corresponding physical entity. Note, an alarm indicates
a condition, not an event. An alarm has two states:
'asserted' Indicates that the condition described by the
alarm exists.
'cleared' Indicates that the condition described by the
alarm does not exist.
For example, a slot in a chassis may define an alarm that
specifies whether the slot contains a module. At the time of
module insertion, the physical entity corresponding to the slot
asserts this alarm, and the alarm remains asserted until the
slot becomes empty.
If an alarm is being asserted by the physical entity, then the
corresponding bit in the alarm list is set to a one. Observe
that if the physical entity is not currently asserting any
alarms, then the list will have a length of zero. |
