DETAILED PROBLEM DESCRIPTION
Currently in the PCMM specification a single gate is restricted from using multiple classifier types; thus an individual
gate cannot be setup to handle both IPv4 and IPv6 traffic. This complicates the ability to dynamically setup QoS for
dual-stack devices as well for situations where the eventual IP stack used by an application cannot be predicted. This
ECR removes this restriction enabling PCMM gates to support both IPv4 and IPv6 classification simultaneously.
PROPOSED SPECIFICATION CHANGES (Please include section number, title, and paragraph)
Please note Engineering Changes may only address one technical issue in one specification, although it may require changes to
multiple sections in the specification. Please itemize each change as follows. If you have multiple changes and some are technical
and some are editorial (but all address the same issue), please indicate which is which in addition to selecting “both” under the
type of change above. Note: Technical changes may require a vendor to change the design of the product. Editorial changes are
points of clarification or clean-up but would not generally require a change to the product.

A PS MUST support all three types of classifiers specified here. A CMTS MUST support both
legacy and Extended Classifiers. A CMTS that supports DOCSIS 3.0 MUST support the IPv6
Classifier. An Application Manager MUST use only one classifier type per Gate-Set, and MUST
continue to use that type for all subsequent Gate-Sets for that Gate.

Extended only one classifier type per Gate-Set, and MUST continue to use that type for all
subsequent Gate-Sets for that Gate. If both IPv4 and IPv6 based classification are required in a GateSet an Application Manager MUST use the Extended Classifier for the IPv4 classification and
logically the IPv6 Classifier for the IPv6 classification.

(New text perhaps at the end of this section)
In the case of the IPv6 Classifier object, the CMTS SHOULD validate the corresponding cable
modem referenced by the Gate-Set supports IPv6 as indicated by the modem capabilities TLV 5.39
“IPv6 Support”. If only IPv6 classifiers are present in the Gate-Set and the modem does NOT
indicate IPv6 support a Gate-Set-Err SHOULD be returned. If both IPv6 and Extended classifiers
are present in the Gate-Set and the modem does NOT indicate IPv6 support the CMTS MAY
proceed with the IPv4 classifier mapping and gate establishment/modification while silently
discarding the IPv6 classifier mapping aspect.
