STATUS_FWP_INVALID_WEIGHT
The arbitration priority cannot be derived from the supplied weight
STATUS_FWP_INVALID_WEIGHT concerns filter arbitration, not traffic volume or interface metric. WFP accepts a direct FWP_UINT64 weight, an automatic FWP_EMPTY weight, or an FWP_UINT8 range identifier from 0 through 15. Other type and value combinations cannot produce a valid filter priority.
Inspect both the tagged type and its value. A 64-bit number placed in the wrong union member, or a range identifier outside 0 through 15, is not repaired by moving the filter to another layer. Keep effective weights from a successful installation when comparing policy arbitration.
What to inspect
- The
FWP_VALUE0.typeused for weight and the corresponding union member. - Whether the intended policy uses direct priority, automatic weighting, or one of the 16 ranges.
- The target sublayer and neighboring filters whose order affects the observed result.
- The effective weight reported by BFE after a successful comparable filter is installed.
