WSA_QOS_EPSFILTERSPEC
The nested sender selector does not match its declared filter form
WSA_QOS_EPSFILTERSPEC means a FILTERSPEC referenced from a provider-specific FLOWDESCRIPTOR is invalid. The provider uses these filters to select packets or senders covered by the reservation, so an address-family mismatch, unsupported filter type, invalid port representation, or dangling list pointer prevents correct classification.
Identify the descriptor and filter index, then decode the union according to FilterType. Confirm that IPv4 and IPv6 structures match the RSVP session, that ports are in the required byte order, and that the sender set is legal for the selected reservation style. A syntactically repaired filter can still select the wrong traffic, so compare it with packet captures or the application’s actual source address and port.
Filter evidence needed for correction
- Descriptor and filter indexes.
- FilterType and active union member.
- Address, port, protocol, or flow label.
- Reservation style and intended sender.
