| alarmIrpMIB | 1.3.6.1.4.1.3881.2 | | | This SNMP MIB-module constitutes the Ericsson Alarm
Integration Reference Point (IRP) solution set for SNMP,
version 1:2.
The purpose of this IRP is to define an interface though
which a 'system' (typically a network element manager or
a network element) can communicate alarm information for
its managed objects to one or several 'actors' (typically
network management systems).
An alarm is a kind of object that represents an abnormal
condition for a managed object. An alarm is active as
long as the corresponding abnormal condition remains. The
system maintains an 'Alarm Table' containing all currently
active alarms for its managed objects. When an alarm is
cleared, it is removed from the list and no longer
accessible.
Alarms can be forwarded to the actors either
synchronously (requested through get, get-next or get-
bulk PDUs) or asynchrously (through inform or trap PDUs)
whenever an entry in the Alarm Table is created, modified
or cleared. |
| alarmObjects | 1.3.6.1.4.1.3881.2.1 | | | |
| OCT alarmIrpVersion | 1.3.6.1.4.1.3881.2.1.1 | OCTET STRING | read-only | This object represents the version of the Alarm IRP
SNMPv2 Solution Set supported by the agent. The
format is 'xy', where 'x' is the version of the
information model and 'y' the version of the solution
set corresponding to this information model. |
| I32 alarmIndeterminateNumber | 1.3.6.1.4.1.3881.2.1.2 | Integer32 | read-only | This object determines the number of currently
active alarms with perceived severity 'indeterminate'. |
| I32 alarmCriticalNumber | 1.3.6.1.4.1.3881.2.1.3 | Integer32 | read-only | This object determines the number of currently
active alarms with perceived severity 'critical'. |
| I32 alarmMajorNumber | 1.3.6.1.4.1.3881.2.1.4 | Integer32 | read-only | This object determines the number of currently
active alarms with perceived severity 'major'. |
| I32 alarmMinorNumber | 1.3.6.1.4.1.3881.2.1.5 | Integer32 | read-only | This object determines the number of currently
active alarms with perceived severity 'minor'. |
| I32 alarmWarningNumber | 1.3.6.1.4.1.3881.2.1.6 | Integer32 | read-only | This object determines the number of currently
active alarms with perceived severity 'warning'. |
| I32 alarmNumber | 1.3.6.1.4.1.3881.2.1.7 | Integer32 | read-only | This object determines the total number of
currently active alarms, i.e. the total number
of entries in the Alarm Table. |
| alarmTable | 1.3.6.1.4.1.3881.2.1.8 | | not-accessible | Table with information about the alarms that are
currently active in the system. |
| alarmEntry | 1.3.6.1.4.1.3881.2.1.8.1 | | not-accessible | One entry in the table holds one current alarm. |
| I32 alarmId | 1.3.6.1.4.1.3881.2.1.8.1.1 | Integer32 | read-only | This object uniquely identifies an entry in the
Alarm Table. It increases every time a new alarm
occurs. Due to cleared alarms the index will not be
contiguous. When the maximum is reached of
Integer32, the value of this object rolls over to 1.
The actor must use 'alarmEventTime' to sort on
chronological order.
The alarmId object is read-only even though it
is used as index in the Alarm Table. The reason is
that this facilities a convenient way to extract
the corresponding value from a notification where
the object is included. |
| MAN alarmManagedObjectClass | 1.3.6.1.4.1.3881.2.1.8.1.2 | ManagedObjectClass | read-only | This object identifies the class of network
resources to which the subject alarm is related. |
| MAN alarmManagedObjectInstance | 1.3.6.1.4.1.3881.2.1.8.1.3 | ManagedObjectInstance | read-only | This object identifies the instance (of a class) of
network resource to which the subject alarm is
related. |
| DAT alarmEventTime | 1.3.6.1.4.1.3881.2.1.8.1.4 | DateAndTime | read-only | This object represents the time of occurrence of the
subject alarm. If the alarm changes 'perceivedSeverity',
then this object represents the time of the last
severity change, else it represents the time carried in
the original alarm emitted by the alarmed network
resource. The time indication is in UTC (Co-ordinated
Universal Time). |
| TYP alarmEventType | 1.3.6.1.4.1.3881.2.1.8.1.5 | TypeOfEvent | read-only | This object represents the type of event according
to the ITU recommendations X.733/X.736. |
| PRO alarmProbableCause | 1.3.6.1.4.1.3881.2.1.8.1.6 | ProbableCause | read-only | This object represents the probable cause
identification code (generic classification) for the
subject alarm according to the ITU recommendations
M.3100/X.733/X.736 and ETSI recommendation GSM 12.11. |
| PER alarmPerceivedSeverity | 1.3.6.1.4.1.3881.2.1.8.1.7 | PerceivedSeverity | read-only | This object represents the perceived severity of
the subject alarm according to the ITU
recommendation X.733.
If the system changes the perceived severity of
an existing alarm to a higher value, the
corresponding 'alarmAckUser' and 'alarmAckTime'
objects are cleared. |
| STR alarmSpecificProblem | 1.3.6.1.4.1.3881.2.1.8.1.8 | DisplayString80 | read-only | This object represents the specific problem
identification code for the subject alarm. This is a
more detailed (product specific) identification
compared to the (generic) 'alarmprobableCause'. |
| STR alarmAckUser | 1.3.6.1.4.1.3881.2.1.8.1.9 | DisplayString80 | read-write | This object is used to define the id of a user that
acknowledge the subject alarm. An alarm can be
unacknowledged by clearing this object. This object
shall always be set or cleared in the same set
request as the 'alarmAckTime' object defined below.
The system will respond with 'inconsistentValue'
upon attempts to set this object without setting
'alarmAckTime'. |
| DAT alarmAckTime | 1.3.6.1.4.1.3881.2.1.8.1.10 | DateAndTime | read-write | This object represents the time when the subject alarm
was acknowledged. This object shall always be set or
cleared in the same set request as the 'alarmAckUser'
object defined above. The system will respond with
'inconsistentValue' upon attempts to set this object
without setting 'alarmAckTime'. The time indication is in
UTC (Co-ordinated Universal Time). |
| STR alarmAdditionalText | 1.3.6.1.4.1.3881.2.1.8.1.13 | DisplayString200 | read-only | This object represents some arbitrary additional
text for the subject alarm. |
| I32 notificationId | 1.3.6.1.4.1.3881.2.1.9 | Integer32 | accessible-for-notify | This object uniquely identifies a notification. It
increases every time a new notification is sent. When
the maximum is reached of Integer32, the value of
this object rolls over to 1. |
| alarmNotifications | 1.3.6.1.4.1.3881.2.2 | | | |
| alarmNotificationPrefix | 1.3.6.1.4.1.3881.2.2.0 | | | |
| NTF alarmNew | 1.3.6.1.4.1.3881.2.2.0.1 | | | This notification is sent when a new Alarm is
generated and stored in the Alarm Table.
Note that the notification does not include all
objects for the corresponding entry in the Alarm
Table. The reason is that some environments may have
problems with large PDUs. Thus, the notification
receiver must get the missing objects from the
Alarm Table. |
| NTF alarmChanged | 1.3.6.1.4.1.3881.2.2.0.2 | | | This notification is generated when any of the
attributes of an Alarm has changed. Note that
the EventTime value in the notification will be
different than that in the original notifyNewAlarm
if and only if the alarmPerceivedSeverity value
is different from that carried in original
notifyNewAlarm.
Note that the notification does not include all
objects for the corresponding entry in the Alarm
Table. The reason is that some environments may have
problems with large PDUs. Thus, the notification
receiver must get the missing objects from the
Alarm Table. |
| NTF alarmCleared | 1.3.6.1.4.1.3881.2.2.0.3 | | | This notification is generated when an alarm is
cleared. A cleared alarm is removed from the
Alarm Table and is no longer accessible. |
| alarmConformance | 1.3.6.1.4.1.3881.2.3 | | | |
| alarmCompliances | 1.3.6.1.4.1.3881.2.3.1 | | | |
| alarmCompliance | 1.3.6.1.4.1.3881.2.3.1.1 | | | A collection of objects that are required for
compliance to the ALARM-IRP. |
| alarmGroups | 1.3.6.1.4.1.3881.2.3.2 | | | |
| alarmAdminMandatoryGroup | 1.3.6.1.4.1.3881.2.3.2.1 | | | A collection of mandatory objects holding administrative
information. |

the number of currently active alarms. |
| alarmMandatoryGroup | 1.3.6.1.4.1.3881.2.3.2.3 | | | A collection of objects that represents mandatory
alarm attributes. |
| alarmOptionalGroup | 1.3.6.1.4.1.3881.2.3.2.4 | | | A collection of objects that represents optional
alarm attributes. |
| alarmNotificationMandatoryGroup | 1.3.6.1.4.1.3881.2.3.2.5 | | | A collection of mandatory alarm notifications. |
| alarmNotificationOptionalGroup | 1.3.6.1.4.1.3881.2.3.2.6 | | | A collection of optional alarm notifications. |
