IndexIntegerNextFree ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "d"
    STATUS   current
    DESCRIPTION
       "An integer which may be used as a new Index in a table.

       The special value of 0 indicates that no more new entries can be
       created in the relevant table.

       When a MIB is used for configuration, an object with this SYNTAX
       always contains a legal value (if non-zero) for an index that is
       not currently used in the relevant table. The Command Generator
       (Network Management Application) reads this variable and uses the
       (non-zero) value read when creating a new row with an SNMP SET.
       When the SET is performed, the Command Responder (agent) must
       determine whether the value is indeed still unused; Two Network
       Management Applications may attempt to create a row
       (configuration entry) simultaneously and use the same value. If
       it is currently unused, the SET succeeds and the Command
       Responder (agent) changes the value of this object, according to
       an implementation-specific algorithm.  If the value is in use,

       however, the SET fails.  The Network Management Application must
       then re-read this variable to obtain a new usable value.

       An OBJECT-TYPE definition using this SYNTAX MUST specify the
       relevant table for which the object is providing this
       functionality."

-- process data flowing along specific data path.  This table should
-- have at most two entries for each interface capable of
-- Differentiated Services processing on this device: ingress and
-- egress.

-- Note that Differentiated Services Functional Data Path Elements
-- linked together using their individual next pointers and anchored by
-- an entry of the diffServDataPathTable constitute a functional data

-- Classifier Table
--
-- The Classifier Table allows multiple classifier elements, of same or
-- different types, to be used together. A classifier must completely
-- classify all packets presented to it. This means that all traffic
-- presented to a classifier must match at least one classifier element
-- within the classifier, with the classifier element parameters
-- specified by a filter.

-- If there is ambiguity between classifier elements of different
-- classifier, classifier linkage order indicates their precedence; the
-- first classifier in the link is applied to the traffic first.

-- Entries in the classifier element table serves as the anchor for
-- each classification pattern, defined in filter table entries.  Each
-- classifier element table entry also specifies the subsequent
-- downstream Differentiated Services Functional Data Path Element when
-- the classification pattern is satisfied. Each entry in the
-- classifier element table describes one branch of the fan-out
-- characteristic of a classifier indicated in the Informal
-- Differentiated Services Model section 4.1.  A classifier is composed
-- of one or more classifier elements.

       data path elements of this device.  The actual classification
       definitions are defined in diffServClfrElementTable entries
       belonging to each classifier.

       An entry in this table, pointed to by a RowPointer specifying an
       instance of diffServClfrStatus, is frequently used as the name
       for a set of classifier elements, which all use the index
       diffServClfrId. Per the semantics of the classifier element
       table, these entries constitute one or more unordered sets of
       tests which may be simultaneously applied to a message to

       classify it.

       The primary function of this table is to ensure that the value of
       diffServClfrId is unique before attempting to use it in creating
       a diffServClfrElementEntry. Therefore, the diffServClfrEntry must

       diffServClfrElementSpecific points to a filter that specifies the

       different types together.

       One example of a filter table defined in this MIB is
       diffServMultiFieldClfrTable, for IP Multi-Field Classifiers
       (MFCs). Such an entry might identify anything from a single
       micro-flow (an identifiable sub-session packet stream directed
       from one sending transport to the receiving transport or
       transports), or aggregates of those such as the traffic from a
       host, traffic for an application, or traffic between two hosts
       using an application and a given DSCP. The standard Behavior
       Aggregate used in the Differentiated Services Architecture is
       encoded as a degenerate case of such an aggregate - the traffic
       using a particular DSCP value.

       Filter tables for other filter types may be defined elsewhere."

-- This MIB supports a variety of Meters.  It includes a specific
-- definition for Token Bucket Meter, which are but one type of
-- specification. Other metering parameter sets can be defined in other
-- MIBs.

-- Multiple meter elements may be logically cascaded using their
-- diffServMeterSucceedNext and diffServMeterFailNext pointers if
-- required. One example of this might be for an AF PHB implementation
-- that uses multiple level conformance meters.

-- Cascading of individual meter elements in the MIB is intended to be
-- functionally equivalent to multiple level conformance determination
-- of a packet.  The sequential nature of the representation is merely
-- a notational convenience for this MIB.

-- srTCM meters (RFC 2697) can be specified using two sets of
-- diffServMeterEntry and diffServTBParamEntry. The first set specifies
-- the Committed Information Rate and Committed Burst Size
-- token-bucket.  The second set specifies the Excess Burst Size
-- token-bucket.

-- trTCM meters (RFC 2698) can be specified using two sets of
-- diffServMeterEntry and diffServTBParamEntry. The first set specifies
-- the Committed Information Rate and Committed Burst Size
-- token-bucket.  The second set specifies the Peak Information Rate
-- and Peak Burst Size token-bucket.

-- tswTCM meters (RFC 2859) can be specified using two sets of
-- diffServMeterEntry and diffServTBParamEntry. The first set specifies
-- the Committed Target Rate token-bucket.  The second set specifies

-- the Peak Target Rate token-bucket. diffServTBParamInterval in each
-- token bucket reflects the Average Interval.

       In the tailDrop(2) algorithm, diffServAlgDropQThreshold
       represents the maximum depth of the queue, pointed to by
       diffServAlgDropQMeasure, beyond which all newly arriving packets
       will be dropped.

       In the headDrop(3) algorithm, if a packet arrives when the
       current depth of the queue, pointed to by
       diffServAlgDropQMeasure, is at diffServAlgDropQThreshold, packets
       currently at the head of the queue are dropped to make room for
       the new packet to be enqueued at the tail of the queue.

       In the randomDrop(4) algorithm, on packet arrival, an Active
       Queue Management algorithm is executed which may randomly drop a
       packet. This algorithm may be proprietary, and it may drop either
       the arriving packet or another packet in the queue.
       diffServAlgDropSpecific points to a diffServRandomDropEntry that
       describes the algorithm. For this algorithm,

       diffServAlgDropQThreshold is understood to be the absolute
       maximum size of the queue and additional parameters are described
       in diffServRandomDropTable.

       The alwaysDrop(5) algorithm is as its name specifies; always
       drop. In this case, the other configuration values in this Entry
       are not meaningful; There is no useful 'next' processing step,
       there is no queue, and parameters describing the queue are not

-- Minimum Rate Parameters Table
--
-- The parameters used by a scheduler for its inputs or outputs are
-- maintained separately from the Queue or Scheduler table entries for

-- schedulers.  This follows the approach for separation of data path
-- elements from parameterization that is used throughout this MIB.
-- Use of these Minimum Rate Parameter Table entries by Queues and
-- Schedulers allows the modeling of hierarchical scheduling systems.
--
-- Specifically, a Scheduler has one or more inputs and one output.
-- Any queue feeding a scheduler, or any scheduler which feeds a second
-- scheduler, might specify a minimum transfer rate by pointing to an
-- Minimum Rate Parameter Table entry.
--
-- The diffServMinRatePriority/Abs/Rel attributes are used as
-- parameters to the work-conserving portion of a scheduler:
-- "work-conserving" implies that the scheduler can continue to emit
-- data as long as there is data available at its input(s).  This has
-- the effect of guaranteeing a certain priority relative to other
-- scheduler inputs and/or a certain minimum proportion of the
-- available output bandwidth. Properly configured, this means a
-- certain minimum rate, which may be exceeded should traffic be
-- available should there be spare bandwidth after all other classes
-- have had opportunities to consume their own minimum rates.

-- Maximum Rate Parameter Table
--
-- The parameters used by a scheduler for its inputs or outputs are
-- maintained separately from the Queue or Scheduler table entries for
-- reusability reasons and so that they may be used by both queues and
-- schedulers.  This follows the approach for separation of data path
-- elements from parameterization that is used throughout this MIB.
-- Use of these Maximum Rate Parameter Table entries by Queues and
-- Schedulers allows the modeling of hierarchical scheduling systems.
--
-- Specifically, a Scheduler has one or more inputs and one output.
-- Any queue feeding a scheduler, or any scheduler which feeds a second
-- scheduler, might specify a maximum transfer rate by pointing to a
-- Maximum Rate Parameter Table entry. Multi-rate shapers, such as a

-- Dual Leaky Bucket algorithm, specify their rates using multiple
-- Maximum Rate Parameter Entries with the same diffServMaxRateId but
-- different diffServMaxRateLevels.
--
-- The diffServMaxRateLevel/Abs/Rel attributes are used as
-- parameters to the non-work-conserving portion of a scheduler:
-- non-work-conserving implies that the scheduler may sometimes not
-- emit a packet, even if there is data available at its input(s).
-- This has the effect of limiting the servicing of the queue/scheduler
-- input or output, in effect performing shaping of the packet stream
-- passing through the queue/scheduler, as described in the Informal
-- Differentiated Services Model section 7.2.
