    DESCRIPTION
       "The status of this conceptual row. All writable objects in this
       row may be modified at any time. Setting this variable to
       'destroy' when the MIB contains one or more RowPointers pointing
       to it results in destruction being delayed until the row is no

diffServQueue          OBJECT IDENTIFIER ::= { diffServMIBObjects 7 }

--
-- An entry of diffServQTable represents a FIFO queue Differentiated
-- Services Functional Data Path element as described in the Informal
-- Differentiated Services Model section 7.1.1. Note that the
-- specification of scheduling parameters for a queue as part of the
-- input to a scheduler functional data path element as described in
-- the Informal Differentiated Services Model section 7.1.2. This
-- allows building of hierarchical queuing/scheduling. A queue
-- therefore has these attributes:
--
-- 1. Which scheduler will service this queue, diffServQNext.
-- 2. How the scheduler will service this queue, with respect
--    to all the other queues the same scheduler needs to service,
--    diffServQMinRate.
--
-- Note that upstream Differentiated Services Functional Data Path
-- elements may point to a shared diffServQTable entry as described
-- in the Informal Differentiated Services Model section 7.1.1.

    SYNTAX       IndexIntegerNextFree
    MAX-ACCESS   read-only

    DESCRIPTION
       "This object contains an unused value for diffServQId, or a zero
       to indicate that none exist."

diffServQTable OBJECT-TYPE
    SYNTAX       SEQUENCE OF DiffServQEntry
    MAX-ACCESS   not-accessible
    STATUS       current
    DESCRIPTION
       "The Queue Table enumerates the individual queues.  Note that the
       MIB models queuing systems as composed of individual queues, one
       per class of traffic, even though they may in fact be structured
       as classes of traffic scheduled using a common calendar queue, or
       in other ways."
    ::= { diffServQueue 2 }

diffServQEntry OBJECT-TYPE
    SYNTAX       DiffServQEntry
    MAX-ACCESS   not-accessible
    STATUS       current
    DESCRIPTION
       "An entry in the Queue Table describes a single queue or class of
       traffic."

diffServQId OBJECT-TYPE
    SYNTAX       IndexInteger
    MAX-ACCESS   not-accessible
    STATUS       current
    DESCRIPTION
       "An index that enumerates the Queue entries.  Managers obtain new
       values for row creation in this table by reading
       diffServQNextFree."
    ::= { diffServQEntry 1 }

diffServQNext OBJECT-TYPE
    SYNTAX       RowPointer
    MAX-ACCESS   read-create
    STATUS       current
    DESCRIPTION
       "This selects the next Differentiated Services Scheduler.  The
       RowPointer must point to a diffServSchedulerEntry.

       A value of zeroDotZero in this attribute indicates an incomplete
       diffServQEntry instance. In such a case, the entry has no
       operational effect, since it has no parameters to give it
       meaning.

       Setting this to point to a target that does not exist results in
       an inconsistentValue error.  If the row pointed to is removed or
       becomes inactive by other means, the treatment is as if this
       attribute contains a value of zeroDotZero."
    ::= { diffServQEntry 2 }

diffServQMinRate OBJECT-TYPE
    SYNTAX       RowPointer
    MAX-ACCESS   read-create
    STATUS       current
    DESCRIPTION
       "This RowPointer indicates the diffServMinRateEntry that the
       scheduler, pointed to by diffServQNext, should use to service
       this queue.
