SNMP MIB Search

An entry in the data path table indicates the start of a single
Differentiated Services Functional Data Path in this device.
These are associated with individual interfaces, logical or
physical, and therefore are instantiated by ifIndex. Therefore,
the interface index must have been assigned, according to the
procedures applicable to that, before it can be meaningfully
used. Generally, this means that the interface must exist.
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.

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

An entry in the classifier table describes a single classifier.

This selects the first Differentiated Services Functional Data
Path Element to handle traffic for this data path. This
RowPointer should point to an instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServAlgDropEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates that no
Differentiated Services treatment is performed on traffic of this
data path. A pointer with the value zeroDotZero normally
terminates a functional data path.
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.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

The status of this conceptual row. All writable objects in this
row may be modified at any time.

An index that enumerates the classifier entries.  Managers
should obtain new values for row creation in this table by
reading diffServClfrNextFree.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

An index that enumerates the Classifier Element entries.
Managers obtain new values for row creation in this table by
reading diffServClfrElementNextFree.

The relative order in which classifier elements are applied:
higher numbers represent classifier element with higher
precedence.  Classifier elements with the same order must be
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.

This attribute provides one branch of the fan-out functionality
of a classifier described in the Informal Differentiated Services
Model section 4.1.
This selects the next Differentiated Services Functional Data
Path Element to handle traffic for this data path. This
RowPointer should point to an instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServAlgDropEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates no further
Differentiated Services treatment is performed on traffic of this
data path. The use of zeroDotZero is the normal usage for the
last functional data path element of the current data path.
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.

A pointer to a valid entry in another table, filter table, that
describes the applicable classification parameters, e.g. an entry
in diffServMultiFieldClfrTable.
The value zeroDotZero is interpreted to match anything not
matched by another classifier element - only one such entry may
exist for each classifier.
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 element is ignored.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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

longer used.

An index that enumerates the MultiField Classifier filter
entries.  Managers obtain new values for row creation in this
table by reading diffServMultiFieldClfrNextFree.

The type of IP address used by this classifier entry.  While
other types of addresses are defined in the InetAddressType
textual convention, and DNS names, a classifier can only look at
packets on the wire. Therefore, this object is limited to IPv4
and IPv6 addresses.

The IP address to match against the packet's destination IP
address. This may not be a DNS name, but may be an IPv4 or IPv6
prefix.  diffServMultiFieldClfrDstPrefixLength indicates the
number of bits that are relevant.

The length of the CIDR Prefix carried in
diffServMultiFieldClfrDstAddr. In IPv4 addresses, a length of 0
indicates a match of any address; a length of 32 indicates a
match of a single host address, and a length between 0 and 32
indicates the use of a CIDR Prefix. IPv6 is similar, except that
prefix lengths range from 0..128.

The IP address to match against the packet's source IP address.
This may not be a DNS name, but may be an IPv4 or IPv6 prefix.
diffServMultiFieldClfrSrcPrefixLength indicates the number of
bits that are relevant.

The length of the CIDR Prefix carried in
diffServMultiFieldClfrSrcAddr. In IPv4 addresses, a length of 0
indicates a match of any address; a length of 32 indicates a
match of a single host address, and a length between 0 and 32
indicates the use of a CIDR Prefix. IPv6 is similar, except that
prefix lengths range from 0..128.

The value that the DSCP in the packet must have to match this
entry. A value of -1 indicates that a specific DSCP value has not
been defined and thus all DSCP values are considered a match.

The flow identifier in an IPv6 header.

The IP protocol to match against the IPv4 protocol number or the
IPv6 Next- Header number in the packet. A value of 255 means
match all.  Note the protocol number of 255 is reserved by IANA,
and Next-Header number of 0 is used in IPv6.

The minimum value that the layer-4 destination port number in
the packet must have in order to match this classifier entry.

The maximum value that the layer-4 destination port number in
the packet must have in order to match this classifier entry.
This value must be equal to or greater than the value specified
for this entry in diffServMultiFieldClfrDstL4PortMin.

The minimum value that the layer-4 source port number in the
packet must have in order to match this classifier entry.

The maximum value that the layer-4 source port number in the
packet must have in order to match this classifier entry. This
value must be equal to or greater than the value specified for
this entry in diffServMultiFieldClfrSrcL4PortMin.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

An index that enumerates the Meter entries.  Managers obtain new
values for row creation in this table by reading
diffServMeterNextFree.

If the traffic does conform, this selects the next
Differentiated Services Functional Data Path element to handle
traffic for this data path. This RowPointer should point to an
instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServAlgDropEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates that no
further Differentiated Services treatment is performed on traffic
of this data path. The use of zeroDotZero is the normal usage for
the last functional data path element of the current data path.
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.

If the traffic does not conform, this selects the next
Differentiated Services Functional Data Path element to handle
traffic for this data path. This RowPointer should point to an
instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServAlgDropEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates no further
Differentiated Services treatment is performed on traffic of this
data path. The use of zeroDotZero is the normal usage for the
last functional data path element of the current data path.
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.

This indicates the behavior of the meter by pointing to an entry
containing detailed parameters. Note that entries in that
specific table must be managed explicitly.
For example, diffServMeterSpecific may point to an entry in
diffServTBParamTable, which contains an instance of a single set
of Token Bucket parameters.
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 meter always succeeds.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

An index that enumerates the Token Bucket Parameter entries.
Managers obtain new values for row creation in this table by
reading diffServTBParamNextFree.

The Metering algorithm associated with the Token Bucket
parameters.  zeroDotZero indicates this is unknown.
Standard values for generic algorithms:
diffServTBParamSimpleTokenBucket, diffServTBParamAvgRate,
diffServTBParamSrTCMBlind, diffServTBParamSrTCMAware,
diffServTBParamTrTCMBlind, diffServTBParamTrTCMAware, and
diffServTBParamTswTCM are specified in this MIB as OBJECT-
IDENTITYs; additional values may be further specified in other
MIBs.

The token-bucket rate, in kilobits per second (kbps). This
attribute is used for:
1. CIR in RFC 2697 for srTCM
2. CIR and PIR in RFC 2698 for trTCM
3. CTR and PTR in RFC 2859 for TSWTCM
4. AverageRate in RFC 3290.

The maximum number of bytes in a single transmission burst. This
attribute is used for:
1. CBS and EBS in RFC 2697 for srTCM
2. CBS and PBS in RFC 2698 for trTCM
3. Burst Size in RFC 3290.

The time interval used with the token bucket.  For:
1. Average Rate Meter, the Informal Differentiated Services Model
section 5.2.1, - Delta.
2. Simple Token Bucket Meter, the Informal Differentiated
Services Model section 5.1, - time interval t.
3. RFC 2859 TSWTCM, - AVG_INTERVAL.
4. RFC 2697 srTCM, RFC 2698 trTCM, - token bucket update time
interval.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

An index that enumerates the Action entries.  Managers obtain
new values for row creation in this table by reading
diffServActionNextFree.

The interface index (value of ifIndex) that this action occurs
on. This may be derived from the diffServDataPathStartEntry's
index by extension through the various RowPointers. However, as
this may be difficult for a network management station, it is
placed here as well.  If this is indeterminate, the value is
zero.
This is of especial relevance when reporting the counters which
may apply to traffic crossing an interface:
diffServCountActOctets,
diffServCountActPkts,
diffServAlgDropOctets,
diffServAlgDropPkts,
diffServAlgRandomDropOctets, and
diffServAlgRandomDropPkts.
It is also especially relevant to the queue and scheduler which
may be subsequently applied.

This selects the next Differentiated Services Functional Data
Path Element to handle traffic for this data path. This
RowPointer should point to an instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServAlgDropEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates no further
Differentiated Services treatment is performed on traffic of this
data path. The use of zeroDotZero is the normal usage for the
last functional data path element of the current data path.
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.

A pointer to an object instance providing additional information
for the type of action indicated by this action table entry.
For the standard actions defined by this MIB module, this should
point to either a diffServDscpMarkActEntry or a
diffServCountActEntry. For other actions, it may point to an
object instance defined in some other MIB.
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 Meter should be treated as
if it were not present.  This may lead to incorrect policy
behavior.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

The DSCP that this Action will store into the DSCP field of the
subject. It is quite possible that the only packets subject to
this Action are already marked with this DSCP. Note also that
Differentiated Services processing may result in packet being
marked on both ingress to a network and on egress from it, and
that ingress and egress can occur in the same router.

An index that enumerates the Count Action entries.  Managers
obtain new values for row creation in this table by reading
diffServCountActNextFree.

The number of octets at the Action data path element.
Discontinuities in the value of this counter can occur at re-
initialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime on the
relevant interface.

The number of packets at the Action data path element.

An index that enumerates the Algorithmic Dropper entries.
Managers obtain new values for row creation in this table by
reading diffServAlgDropNextFree.

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,
and diffServAlgDropSpecific are all zeroDotZero.

This selects the next Differentiated Services Functional Data
Path Element to handle traffic for this data path. This
RowPointer should point to an instance of one of:
diffServClfrEntry
diffServMeterEntry
diffServActionEntry
diffServQEntry
A value of zeroDotZero in this attribute indicates no further
Differentiated Services treatment is performed on traffic of this
data path. The use of zeroDotZero is the normal usage for the
last functional data path element of the current data path.
When diffServAlgDropType is alwaysDrop(5), this object is
ignored.
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.

Points to an entry in the diffServQTable to indicate the queue
that a drop algorithm is to monitor when deciding whether to drop
a packet. If the row pointed to does not exist, the algorithmic
dropper element is considered inactive.
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.

A threshold on the depth in bytes of the queue being measured at
which a trigger is generated to the dropping algorithm, unless
diffServAlgDropType is alwaysDrop(5) where this object is
ignored.
For the tailDrop(2) or headDrop(3) algorithms, this represents
the depth of the queue, pointed to by diffServAlgDropQMeasure, at
which the drop action will take place. Other algorithms will need
to define their own semantics for this threshold.

Points to a table entry that provides further detail regarding a
drop algorithm.
Entries with diffServAlgDropType equal to other(1) may have this
point to a table defined in another MIB module.
Entries with diffServAlgDropType equal to randomDrop(4) must have
this point to an entry in diffServRandomDropTable.
For all other algorithms specified in this MIB, this should take
the value zeroDotZero.
The diffServAlgDropType is authoritative for the type of the drop
algorithm and the specific parameters for the drop algorithm
needs to be evaluated based on the diffServAlgDropType.
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.

The number of octets that have been deterministically dropped by
this drop process.
Discontinuities in the value of this counter can occur at re-
initialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime on the
relevant interface.

The number of packets that have been deterministically dropped
by this drop process.
Discontinuities in the value of this counter can occur at re-
initialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime on the
relevant interface.

The number of octets that have been randomly dropped by this
drop process.  This counter applies, therefore, only to random
droppers.

initialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime on the

An index that enumerates the Random Drop entries.  Managers
obtain new values for row creation in this table by reading
diffServRandomDropNextFree.

The average queue depth in bytes, beyond which traffic has a
non-zero probability of being dropped. Changes in this variable
may or may not be reflected in the reported value of
diffServRandomDropMinThreshPkts.

The average queue depth in packets, beyond which traffic has a
non-zero probability of being dropped. Changes in this variable
may or may not be reflected in the reported value of
diffServRandomDropMinThreshBytes.

The average queue depth beyond which traffic has a probability
indicated by diffServRandomDropProbMax of being dropped or
marked. Note that this differs from the physical queue limit,
which is stored in diffServAlgDropQThreshold. Changes in this
variable may or may not be reflected in the reported value of
diffServRandomDropMaxThreshPkts.

The average queue depth beyond which traffic has a probability
indicated by diffServRandomDropProbMax of being dropped or
marked. Note that this differs from the physical queue limit,
which is stored in diffServAlgDropQThreshold. Changes in this
variable may or may not be reflected in the reported value of
diffServRandomDropMaxThreshBytes.

The worst case random drop probability, expressed in drops per
thousand packets.
For example, if in the worst case every arriving packet may be
dropped (100%) for a period, this has the value 1000.
Alternatively, if in the worst case only one percent (1%) of
traffic may be dropped, it has the value 10.

The weighting of past history in affecting the Exponentially
Weighted Moving Average function that calculates the current
average queue depth.  The equation uses
diffServRandomDropWeight/65536 as the coefficient for the new
sample in the equation, and (65536 -
diffServRandomDropWeight)/65536 as the coefficient of the old
value.
Implementations may limit the values of diffServRandomDropWeight
to a subset of the possible range of values, such as powers of
two. Doing this would facilitate implementation of the
Exponentially Weighted Moving Average using shift instructions or
registers.

The number of times per second the queue is sampled for queue
average calculation.  A value of zero is used to mean that the
queue is sampled approximately each time a packet is enqueued (or
dequeued).

An index that enumerates the Queue entries.  Managers obtain new
values for row creation in this table by reading
diffServQNextFree.

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.

This RowPointer indicates the diffServMinRateEntry that the
scheduler, pointed to by diffServQNext, should use to service
this queue.
If the row pointed to is zeroDotZero, the minimum rate and

diffServSchedulerNextFree.

This selects the next Differentiated Services Functional Data
Path Element to handle traffic for this data path. This normally
is null (zeroDotZero), or points to a diffServSchedulerEntry or a
diffServQEntry.
However, this RowPointer may also point to an instance of:
diffServClfrEntry,
diffServMeterEntry,
diffServActionEntry,
diffServAlgDropEntry.
It would point another diffServSchedulerEntry when implementing
multiple scheduler methods for the same data path, such as having
one set of queues scheduled by WRR and that group participating
in a priority scheduling system in which other queues compete
with it in that way.  It might also point to a second scheduler
in a hierarchical scheduling system.
If the row pointed to is zeroDotZero, no further Differentiated
Services treatment is performed on traffic of this data path.
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.

The scheduling algorithm used by this Scheduler. zeroDotZero
indicates that this is unknown.  Standard values for generic
algorithms: diffServSchedulerPriority, diffServSchedulerWRR, and
diffServSchedulerWFQ are specified in this MIB; additional values
may be further specified in other MIBs.

This RowPointer indicates the entry in diffServMinRateTable
which indicates the priority or minimum output rate from this
scheduler. This attribute is used only when there is more than
one level of scheduler.
When it has the value zeroDotZero, it indicates that no minimum
rate or priority is imposed.
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.

This RowPointer indicates the entry in diffServMaxRateTable
which indicates the maximum output rate from this scheduler.
When more than one maximum rate applies (eg, when a multi-rate
shaper is in view), it points to the first of those rate entries.
This attribute is used only when there is more than one level of
scheduler.
When it has the value zeroDotZero, it indicates that no maximum
rate is imposed.
Setting this to point to a target that does not exist results in

reading diffServMinRateNextFree.

The priority of this input to the associated scheduler, relative
to the scheduler's other inputs. A queue or scheduler with a
larger numeric value will be served before another with a smaller
numeric value.

The minimum absolute rate, in kilobits/sec, that a downstream
scheduler element should allocate to this queue. If the value is
zero, then there is effectively no minimum rate guarantee. If the
value is non-zero, the scheduler will assure the servicing of
this queue to at least this rate.
Note that this attribute value and that of
diffServMinRateRelative are coupled: changes to one will affect
the value of the other. They are linked by the following
equation, in that setting one will change the other:
diffServMinRateRelative =
(diffServMinRateAbsolute*1000000)/ifSpeed
or, if appropriate:
diffServMinRateRelative = diffServMinRateAbsolute/ifHighSpeed

The minimum rate that a downstream scheduler element should
allocate to this queue, relative to the maximum rate of the
interface as reported by ifSpeed or ifHighSpeed, in units of
1/1000 of 1. If the value is zero, then there is effectively no
minimum rate guarantee. If the value is non-zero, the scheduler
will assure the servicing of this queue to at least this rate.
Note that this attribute value and that of
diffServMinRateAbsolute are coupled: changes to one will affect
the value of the other. They are linked by the following
equation, in that setting one will change the other:
diffServMinRateRelative =
(diffServMinRateAbsolute*1000000)/ifSpeed
or, if appropriate:
diffServMinRateRelative = diffServMinRateAbsolute/ifHighSpeed

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

An index that enumerates the Maximum Rate Parameter entries.
Managers obtain new values for row creation in this table by
reading diffServMaxRateNextFree.

An index that indicates which level of a multi-rate shaper is
being given its parameters. A multi-rate shaper has some number
of rate levels. Frame Relay's dual rate specification refers to a
'committed' and an 'excess' rate; ATM's dual rate specification
refers to a 'mean' and a 'peak' rate. This table is generalized
to support an arbitrary number of rates. The committed or mean
rate is level 1, the peak rate (if any) is the highest level rate
configured, and if there are other rates they are distributed in
monotonically increasing order between them.

The maximum rate in kilobits/sec that a downstream scheduler
element should allocate to this queue. If the value is zero, then
there is effectively no maximum rate limit and that the scheduler
should attempt to be work conserving for this queue. If the value
is non-zero, the scheduler will limit the servicing of this queue
to, at most, this rate in a non-work-conserving manner.
Note that this attribute value and that of
diffServMaxRateRelative are coupled: changes to one will affect
the value of the other. They are linked by the following
equation, in that setting one will change the other:
diffServMaxRateRelative =
(diffServMaxRateAbsolute*1000000)/ifSpeed
or, if appropriate:
diffServMaxRateRelative = diffServMaxRateAbsolute/ifHighSpeed

The maximum rate that a downstream scheduler element should
allocate to this queue, relative to the maximum rate of the
interface as reported by ifSpeed or ifHighSpeed, in units of
1/1000 of 1. If the value is zero, then there is effectively no
maximum rate limit and the scheduler should attempt to be work
conserving for this queue. If the value is non-zero, the
scheduler will limit the servicing of this queue to, at most,
this rate in a non-work-conserving manner.
Note that this attribute value and that of
diffServMaxRateAbsolute are coupled: changes to one will affect
the value of the other. They are linked by the following
equation, in that setting one will change the other:
diffServMaxRateRelative =
(diffServMaxRateAbsolute*1000000)/ifSpeed
or, if appropriate:
diffServMaxRateRelative = diffServMaxRateAbsolute/ifHighSpeed

The number of bytes of queue depth at which the rate of a
multi-rate scheduler will increase to the next output rate. In
the last conceptual row for such a shaper, this threshold is
ignored and by convention is zero.

The storage type for this conceptual row.  Conceptual rows
having the value 'permanent' need not allow write-access to any
columnar objects in the row.

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
longer used.

The data path table contains RowPointers indicating the start of
the functional data path for each interface and traffic direction
in this device. These may merge, or be separated into parallel
data paths.

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.

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.

A table of IP Multi-field Classifier filter entries that a
system may use to identify IP traffic.

This table enumerates specific meters that a system may use to
police a stream of traffic. The traffic stream to be metered is
determined by the Differentiated Services Functional Data Path
Element(s) upstream of the meter i.e. by the object(s) that point
to each entry in this table.  This may include all traffic on an
interface.
Specific meter details are to be found in table entry referenced
by diffServMeterSpecific.

This table enumerates a single set of token bucket meter
parameters that a system may use to police a stream of traffic.
Such meters are modeled here as having a single rate and a single
burst size. Multiple entries are used when multiple rates/burst
sizes are needed.

The Action Table enumerates actions that can be performed to a
stream of traffic. Multiple actions can be concatenated. For
example, traffic exiting from a meter may be counted, marked, and
potentially dropped before entering a queue.
Specific actions are indicated by diffServActionSpecific which
points to an entry of a specific action type parameterizing the
action in detail.

This table enumerates specific DSCPs used for marking or
remarking the DSCP field of IP packets. The entries of this table
may be referenced by a diffServActionSpecific attribute.

This table contains counters for all the traffic passing through
an action element.

The algorithmic drop table contains entries describing an
element that drops packets according to some algorithm.

The random drop table contains entries describing a process that
drops packets randomly. Entries in this table are pointed to by
diffServAlgDropSpecific.

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.

The Scheduler Table enumerates packet schedulers. Multiple
scheduling algorithms can be used on a given data path, with each
algorithm described by one diffServSchedulerEntry.

The Minimum Rate Parameters Table enumerates individual sets of
scheduling parameter that can be used/reused by Queues and
Schedulers.

The Maximum Rate Parameter Table enumerates individual sets of
scheduling parameter that can be used/reused by Queues and
Schedulers.

This MIB defines the objects necessary to manage a device that
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.

For use with diffServSchedulerMethod to indicate the Priority
scheduling method.  This is defined as an algorithm in which the
presence of data in a queue or set of queues absolutely precludes
dequeue from another queue or set of queues of lower priority.

queues/schedulers feeding this scheduler are used when
determining the next packet to schedule.

For use with diffServSchedulerMethod to indicate the Weighted
Round Robin scheduling method, defined as any algorithm in which

diffServMinRateEntry of the queues/schedulers feeding this
scheduler are used when determining the next packet to schedule.
