NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure (ntddndis.h)
The NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure specifies an array of policy properties for a Hyper-V extensible switch port. Each element in the array is formatted as an NDIS_SWITCH_PORT_PROPERTY_ENUM_INFO structure.
Syntax
typedef struct _NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS {
NDIS_OBJECT_HEADER Header;
ULONG Flags;
NDIS_SWITCH_PORT_ID PortId;
NDIS_SWITCH_PORT_PROPERTY_TYPE PropertyType;
NDIS_SWITCH_OBJECT_ID PropertyId;
NDIS_SWITCH_OBJECT_SERIALIZATION_VERSION SerializationVersion;
ULONG FirstPropertyOffset;
ULONG NumProperties;
USHORT Reserved;
} NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS, *PNDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS;
Members
Header
The type, revision, and size of the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure. This member is formatted as an NDIS_OBJECT_HEADER structure.
The Type member of Header must be set to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure, the Revision member of Header must be set to the following value:
NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS_REVISION_1
Original version for NDIS 6.30 and later.
Set the Size member to NDIS_SIZEOF_NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS_REVISION_1.
Flags
A ULONG value that contains a bitwise OR of flags. This member is reserved for NDIS.
PortId
An NDIS_SWITCH_PORT_ID value that contains the unique identifier of the extensible switch port for which properties are enumerated.
PropertyType
An NDIS_SWITCH_PORT_PROPERTY_TYPE enumeration value that specifies the port property type. When an OID method request of OID_SWITCH_PORT_PROPERTY_ENUM is issued, the extensible switch extension returns port properties that match this property type.
PropertyId
A GUID value that identifies the property for the extensible switch port.
SerializationVersion
An NDIS_SWITCH_OBJECT_SERIALIZATION_VERSION value that identifies the format version of the serialized port property data. This data is serialized for access by the extension from the Managed Object Format (MOF) file that defined the property.
FirstPropertyOffset
A USHORT value that specifies the offset, in bytes, to the first NDIS_SWITCH_PORT_PROPERTY_ENUM_INFO element that follows the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure. The offset is measured from the start of the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure up to the beginning of the first element of the array.
NumProperties
A ULONG value that specifies the number of NDIS_SWITCH_PORT_PROPERTY_ENUM_INFO elements that follow the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure.
Reserved
Reserved for future use.
Remarks
The NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure is used in OID method requests of OID_SWITCH_PORT_PROPERTY_ENUM. An array of NDIS_SWITCH_PORT_PROPERTY_ENUM_INFO structures follow the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure in the information buffer that is associated with these OID set requests. The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to this information buffer.
Extensible switch extensions can access the first NDIS_SWITCH_PORT_PROPERTY_ENUM_INFO structure that is specified by the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS structure by using the NDIS_SWITCH_PORT_PROPERTY_ENUM_PARAMETERS_GET_FIRST_INFO macro.
