          Management Information Base (DOCSIS-QoS MIB)

               parameters that describe the current level of service
               provided to a Service Flow (SF).

               QPS.

               parameters that describe a level of service that the
               Service Flow is not currently using, but that it is
               guaranteed to receive upon the SF's request to make
               the set Active.

               network.  DOCSIS CMs operate as a MAC layer bridge

               Radio Frequency (RF) network.

               subscriber.

               message requesting the dynamic creation of a new
               Service Flow.  New SFs are created with a three-
               message exchange of a DSA-REQ, DSA-RSP, and DSA-ACK.

               message requesting a change to the attributes of a
               Service Flow.  SFs are changed with a three-message
               exchange of a DSC-REQ, DSC-RSP, and DSC-ACK.

               message requesting the deletion of a Service Flow.
               SFs are deleted with a two-message exchange of a

               packet on the RF network.

               Upstream Service Flow and a Primary Downstream
               Service Flow.  They provide a default path for
               forwarded packets that are not classified to any
               other Service Flow.

               within which a Service Flow is authorized to request
               admission.  All existing Service Flows must have a
               non-empty Provisioned QPS; thus, all SFs are
               considered to be "Provisioned".

               A Service Flow may or may not be associated with a
               single named Service Class.  A Service Class has as
               an attribute a QoS Parameter Set that is used as the
               default set of values for all Service Flows belonging

                   Figure 1: QoS Parameter Sets

 1.  When a CM initially ranges, the CM implements a row in the
     DOCS-IF-MIB docsIfCmServiceTable, and the CMTS implements a row
     in the DOCS-IF-MIB docsIfCmtsServiceTable corresponding to the
     default upstream Service ID (SID) used for pre-registration

     upstream traffic.  For historical compatibility, a row may be
     created for the docsIfQosProfileTable with default values,
     which may be referenced by the docsIfCmServiceTable entries.

 2.  Both a CMTS and CM implementing this MIB MUST NOT implement
     docsIetfQosParamSetTable or docsIetfQosServiceFlowTable rows
     until after the CM registers with DOCSIS 1.1 or 2.0 modem
     operation.

 3.  When a modem registers with the CMTS as a "DOCSIS 1.1" or
     "DOCSIS 2.0" modem, any exclusively-referenced row in DOCS-IF-
     MIB docsIfQosProfileTable representing the modem's upstream QoS
     profile for pre-registration traffic MUST be removed.
     Multiply-referenced rows may remain.  The
     docsIfCmServiceQosProfile object in the CM's row of

     docsIfCmServiceTable MUST be set to zero.  The
     docsIfCmServiceTable row for the DOCSIS 1.1 or DOCSIS 2.0 modem
     continues to exist, and the various statistic objects in that
     row are incremented.  The CMTS should retain a
     docsIfCmtsServiceTable entry for the DOCSIS 1.1 or DOCSIS 2.0
     CM.

 4.  When a DOCSIS 1.1 or DOCSIS 2.0 modem registers, both the CMTS
     and CM represent all Service Flows described in the modem
     configuration file in docsIetfQosParamSetTable and
     docsIetfQosServiceFlowTable.

 5.  DOCSIS 1.0 modems do not have entries in the DOCS-IETF-QOS-MIB.

      Figure 2: DOCSIS Packet Classification

 1.  The packet is first checked for matches with rows of the
     docsDevIpFilterTable.  If it matches, the matching row provides
     a docsDevFilterPolicyId integer.

 2.  The docsDevFilterPolicyId indexes into one (or more) rows of
     docsDevFilterPolicyTable.  Each row provides an arbitrary
     RowPointer (docsDevFilterPolicyPtr), corresponding to a policy
     to be applied to the packet.

 3.  This MIB module defines a docsIetfQosServiceClassPolicyTable
     whose entries may be pointed to by docsDevFilterPolicyPtr in
     order to classify packets administratively to a named DOCSIS
     Service Class.  The docsIetfQosServiceClassPolicyEntry provides
     a Service Class Name (SCN) as docsIetfQosServiceClassPolicyName
     and a classification rule priority as
     docsIetfQosServiceClassPolicyRulePriority.  These are submitted
     to the device's DOCSIS MAC Layer entity as a special form of
     the MAC_DATA.request primitive, as described in Section E.2.1
     of [4].

 4.  The MAC Layer selects an SFID ("Y") of an active Service Flow
     belonging to the named class, choosing an SF arbitrarily if
     there is more than one.

 5.  The packet is then classified according to the
     docsIetfQosPktClassTable, which may classify the packet to a
     different SFID "X".  Associated with the classifier is a
     docsIetfQosPktClassPriority.

 6.  In the event of a conflict between the SCN-determined SFID and
     the classified SFID, the greater of docsIetfQosPktClassPriority
     and docsIetfQosServiceClassPolicyRulePriority determines which
     SFID is selected to forward the packet.

DESCRIPTION    "This table describes the packet classification
                configured on the CM or CMTS.
                The model is that a packet either received
                as input from an interface or transmitted
                for output on an interface may be compared
                against an ordered list of rules pertaining to
                the packet contents.  Each rule is a row of this
                table.  A matching rule provides a Service Flow
                ID to which the packet is classified.
                All rules need to match for a packet to match
                a classifier.

                The objects in this row correspond to a set of
                Classifier Encoding parameters in a DOCSIS
                MAC management message.  The
                docsIetfQosPktClassBitMap indicates which
                particular parameters were present in the
                classifier as signaled in the DOCSIS message.
                If the referenced parameter was not present
                in the signaled DOCSIS 1.1 and 2.0 Classifier, the
                corresponding object in this row reports a

                Each object in the row corresponds to one or

                The docsIetfQosParamSetBitMap object in the row

                In many cases, even if a QOS Parameter Set parameter

                DOCSIS registration or dynamic service request
                message that created or modified the QOS Parameter
                Set.  A bit is set to 1 when the parameter described
                by the indicated reference section is present
                in the original request.

                Note that when Service Class names are expanded,
                the registration or dynamic response message may
                contain parameters as expanded by the CMTS based

                on a stored service class.  These expanded
                parameters are not indicated by a 1 bit in this
                object.

                Note that even though some QOS Parameter Set
                parameters may not be signaled in a message
                (so that the paramater's bit in this object is 0),
                the DOCSIS specification requires that default
                values be used.  These default values are reported
                as the corresponding object's value in the row.

                Note that BITS objects are encoded most
                significant bit first.  For example, if bits
                1 and 16 are set, the value of this object
                is the octet string '400080'H."

                corresponding values from the named Service Class.

DESCRIPTION    "Payload header suppression mask defines the

                of the docsIetfQosPHSField.

                Each bit of the bit mask specifies whether
                the corresponding byte should be suppressed

                A bit value of '0' indicates that
                the byte should not be suppressed by the sending
                device or restored by the receiving device.

                If the bit mask does not contain a bit for each
                byte in the docsIetfQosPHSField, then the bit mask

::= { docsIetfQosGroups 5 }

 o    The docsIetfQosServiceClassTable provides a template of QOS
      parameters such as maximum rate limits for a named service
      class.  Changing these parameters would allow an attacker to
      obtain an unauthorized class of service.

 o    The docsIetfQosServiceClassPolicyTable applies CMTS vendor
      proprietary policies for packet forwarding, including
      dropping, scheduling, notification, or other policies.
      Changing this table could allow an attacker to deny service to
      all subscribers of the CMTS or could grant the attacker
      unauthorized forwarding policies.

 o    The docsIetfQosServiceFlowLogControl object controls the
      deletion of entries in the docsIetfQosServiceFlowLogTable,
      which acts as a historical "detail record" of DOCSIS Service
      Flow packets and bytes transmitted.  Such records may be used
      for billing purposes, so the unauthorized deletion of the
      records can result in free service.

 o    Unauthorized SNMP GET access of the docsIetfQosPktClassTable
      or docsIetfQosPHSTable can allow an attacker to learn IP
      addresses permitted to have enhanced quality of service, for
      possible spoofing.  This table typically contains the IP
      addresses involved in voice-over-IP sessions, for example.

 o    Unauthorized SNMP GET access of the docsIetfQosParamSetTable
      allows an attacker to learn the names of Service Classes that
      are permitted to have enhanced QoS service, and the values of
      that enhanced service.  That name can be referenced in an
      unauthorized DOCSIS cable modem configuration file to obtain
      enhanced service.

 o    Unauthorized SNMP GET access of the
      docsIetfQosServiceFlowTable can tell an attacker when Service
      Flows are active, e.g., when a voice-over-IP call is in
      progress.

      Unauthorized SNMP GET access of the
      docsIetfQosServiceFlowLogTable can expose private information
      about network usage.

 o    Unauthorized SNMP GET access of the
      docsIetfQosServiceFlowStatsTable,
      docsIetfQosUpstreamStatsTable,
      docsIetfQosDynamicServiceStatsTable,
      docsIetfQosServiceFlowLogTable, and
      docsIetfQosCmtsMacToSrvFlowTable can tell an attacker the
      volume of traffic to and from any Service Flow in the system,
      resulting in loss of privacy of the amount and direction of
      data transfer.
