DESCRIPTION
"The MIB module describes a generic solution
to model alarms and to store the current list
of active alarms.
Copyright (C) The Internet Society (2004). The
initial version of this MIB module was published
in RFC 3877. For full legal notices see the RFC
itself. Supplementary information may be available on:
http://www.ietf.org/copyrights/ianamib.html"

-- Textual Conventions
-- ResourceId is intended to be a general textual convention

-- Alarm Management.
ResourceId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A unique identifier for this resource.
The type of the resource can be determined by looking
at the OID that describes the resource.
Resources must be identified in a consistent manner.
For example, if this resource is an interface, this
object MUST point to an ifIndex and if this resource
is a physical entity [RFC2737], then this MUST point
to an entPhysicalDescr, given that entPhysicalIndex
is not accessible. In general, the value is the
name of the instance of the first accessible columnar
object in the conceptual row of a table that is
meaningful for this resource type, which SHOULD
be defined in an IETF standard MIB."

DESCRIPTION
"The index into the varbind listing of the notification
indicated by alarmModelNotificationId which helps
signal that the given alarm has changed state.
If there is no applicable varbind, the value of this

Note that the value of alarmModelVarbindIndex acknowledges
the existence of the first two obligatory varbinds in
the InformRequest-PDU and SNMPv2-Trap-PDU (sysUpTime.0

the snmpTrapOID.0.

DESCRIPTION
"The name portion of each VarBind in the notification,
in order, is compared to the value of this object.
If the name is equal to or a subtree of the value
of this object, for purposes of computing the value
of AlarmActiveResourceID the 'prefix' will be the
matching portion, and the 'indexes' will be any
remainder. The examination of varbinds ends with
the first match. If the value of this object is 0.0,
then the first varbind, or in the case of v2, the
first varbind after the timestamp and the trap
OID, will always be matched.

alarmModelRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create

DESCRIPTION
"Control for creating and deleting entries. Entries may be
modified while active. Alarms whose alarmModelRowStatus is
not active will not appear in either the alarmActiveTable
or the alarmClearTable. Setting this object to notInService
cannot be used as an alarm suppression mechanism. Entries
that are notInService will disappear as described in RFC2579.
This row cannot be modified while it is being
referenced by a value of alarmActiveModelPointer. In these
cases, an error of `inconsistentValue' will be returned to
the manager.
This entry may be deleted while it is being
referenced by a value of alarmActiveModelPointer. This results
in the deletion of this entry and entries in the active alarms
referencing this entry via an alarmActiveModelPointer.
As all read-create objects in this table have a DEFVAL clause,
there is no requirement that any object be explicitly set
before this row can become active. Note that a row consisting
only of default values is not very meaningful."

An implementation may allow multiple named alarm lists, up to

OBJECTS { alarmActiveModelPointer,

STATUS current
DESCRIPTION
"An instance of the alarm indicated by
alarmActiveModelPointer has been cleared against
the entity indicated by alarmActiveResourceId.
The agent must throttle the generation of
consecutive alarmActiveClear traps so that there is at
least a two-second gap between traps of this
type against the same alarmActiveModelPointer and
alarmActiveResourceId. When traps are throttled,
they are dropped, not queued for sending at a future time.
A management application should periodically check
the value of alarmActiveLastChanged to detect any
missed alarmClearState notification-events, e.g.,
due to throttling or transmission loss."
