Description: Provides a collection of referenceable entries to which diffServClfrElementSpecific refers. This table provides filter group indices that can be compared with those signaled during DOCSIS registration. A packet matches an entry from this table if the packet originated from or is destined to a cable modem that registered this index as one of its four filter groups (see docsSubMgtCmFilterTable), and if the packet direction and MAC address select the use of this index among the four.
