    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,

Top      Up      ToC       Page 39 
       however, the SET fails.  The Network Management Application must
       then re-read this variable to obtain a new usable value.

-- 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.

       An entry in this table, pointed to by a RowPointer specifying an

       for a set of classifier elements, which all use the index
       diffServClfrId. Per the semantics of the classifier element

       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

Top      Up      ToC       Page 53
