docsSubMgtFilterGroupIndex
Module: DOCS-IETF-SUBMGT-MIB
OID (symbolic): DOCS-IETF-SUBMGT-MIB::docsSubMgtFilterGroupIndex
OID (numeric): 1.3.6.1.2.1.125.1.7.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The filter group index, from the set signaled at DOCSIS
Registration. Provides a referenceable entry to which diffServClfrElementSpecific points. A packet matches this classifier entry if the packet's cable modem registered this index value as one of its four filter groups, and if the packet direction and MAC address select the use of this index among the four. Because this is the only field in this table, it is read-only, contrary to the usual SMI custom of making indices not-accessible.
Note that although zero may be signaled (or defaulted) at DOCSIS Registration to indicate a default filtering group, no such entry appears in this table, as diffServClfrElementSpecific will use a zeroDotZero pointer for that classification.
What is docsSubMgtFilterGroupIndex?
This read-only integer is the filter group index, drawn from the set signaled at DOCSIS registration, that provides a referenceable entry pointed to by diffServClfrElementSpecific; it is read-only rather than not-accessible because it's the only column in its table. Admins use it to trace which classifier entry corresponds to a filter group number a modem registered, since a packet matches this entry when the modem's registered index and the packet's direction and MAC address select it. For example, an admin cross-referencing this index against diffServClfrElementTable can determine exactly which classification rule applies to a modem's traffic in a given direction.
