| Description | This object describes a set of filter or classifier
criteria. Classifiers are assigned by group to the
individual CMs. That assignment is made via the 'Subscriber
Management TLVs' encodings sent upstream from
the CM to the CMTS during registration or in their
absence, default values configured in the CMTS.
A Filter Group ID (GrpId) is a set of rules that correspond
to the expansion of a UDC Group ID into UDC individual
classification rules. The Filter Group Ids are generated
whenever the CMTS is configured to send UDCs during the CM
registration process. Implementation of L2 classification
criteria is optional for the CMTS; LLC/MAC upstream and
downstream filter criteria can be ignored during the packet
matching process. |
