STATUS_NDIS_MULTICAST_FULL
The adapter has reached its multicast filter capacity
STATUS_NDIS_MULTICAST_FULL is usually tied to an Ethernet multicast-list set request rather than to IP routing. NDIS and overlying protocol drivers use OID_802_3_MULTICAST_LIST to replace the enabled multicast receive list on a miniport adapter. The adapter advertises its maximum list size separately, so a failure here means the requested list cannot fit the miniport or hardware filtering contract.
Do not diagnose this as a cable or gateway issue. The useful evidence is the requested address count, the adapter's MaxMulticastListSize, and whether filters or protocol bindings are expanding the effective list. If the workload really requires more groups, the fallback is normally a different receive-filtering mode or a driver/device change, not another retry with the same list.
Evidence that narrows it
- Compare the submitted multicast address count with the miniport's advertised maximum.
- Check whether multiple protocol bindings or filters are combining multicast requirements.
- Separate multicast-list exhaustion from packet-filter changes such as all-multicast or promiscuous reception.
