Important The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

When queried, the OID_DOT11_SUPPORTED_MULTICAST_ALGORITHM_PAIR object identifier (OID) requests that the miniport driver return a list of the authentication and cipher algorithms that the 802.11 station supports for multicast and broadcast packets.

The data type for this OID is the DOT11_AUTH_CIPHER_PAIR_LIST structure.

When OID_DOT11_SUPPORTED_MULTICAST_ALGORITHM_PAIR is queried, the miniport driver only returns 802.11 authentication and cipher algorithms that the 802.11 station supports for the current value of the IEEE dot11DesiredBSSType management information base (MIB) object. For more information about this MIB object, see OID_DOT11_DESIRED_BSS_TYPE.

Note For each value of the dot11DesiredBSSType MIB object, the miniport driver must not change the list of the 802.11 authentication and cipher algorithms after the OID_DOT11_SUPPORTED_MULTICAST_ALGORITHM_PAIR is queried.

There must be at least one cipher algorithm defined for each supported authentication algorithm. If the miniport driver does not support any multicast cipher algorithms for a particular authentication algorithm, it must still create a list entry for the authentication algorithm and use DOT11_CIPHER_ALGO_NONE for the related cipher algorithm.



Available in Windows Vista and later versions of the Windows operating systems.
