uses the Differentiated Services Architecture described in RFC
2475. The Conceptual Model of a Differentiated Services Router
provides supporting information on how such a router is modeled."

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."

"An entry in the data path table indicates the start of a single

These are associated with individual interfaces, logical or

the interface index must have been assigned, according to the
procedures applicable to that, before it can be meaningfully

When diffServDataPathStorage is of type nonVolatile, however,
this may reflect the configuration for an interface whose ifIndex
has been assigned but for which the supporting implementation is
not currently present."

-- 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.

SYNTAX SEQUENCE OF DiffServClfrEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table enumerates all the diffserv classifier functional
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
be created on the same SET as the diffServClfrElementEntry, or
before the diffServClfrElementEntry is created."

DESCRIPTION
"The classifier element table enumerates the relationship between
classification patterns and subsequent downstream Differentiated
Services Functional Data Path elements.
diffServClfrElementSpecific points to a filter that specifies the
classification parameters. A classifier may use filter tables of
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."

"The relative order in which classifier elements are applied:
higher numbers represent classifier element with higher

unambiguous i.e. they must define non-overlapping patterns, and
are considered to be applied simultaneously to the traffic
stream. Classifier elements with different order may overlap in
their filters: the classifier element with the highest order
that matches is taken.
On a given interface, there must be a complete classifier in
place at all times in the ingress direction. This means one or
more filters must match any possible pattern. There is no such
requirement in the egress direction."

DESCRIPTION
"The type of algorithm used by this dropper. The value other(1)
requires further specification in some other MIB module.
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
useful. Therefore, diffServAlgDropNext, diffServAlgDropMeasure,
