OID_SWITCH_PROPERTY_ENUM

The Hyper-V extensible switch extension issues an object identifier (OID) method request of OID_SWITCH_PROPERTY_ENUM to obtain an array. This array contains the provisioned switch policies that match the specified criteria. Each element in the array specifies the properties of an extensible switch policy.

The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to a buffer. This buffer contains the following data:

Remarks

The OID_SWITCH_PROPERTY_ENUM OID must only be issued when the Hyper-V extensible switch has completed activation. Please see Querying the Hyper-V Extensible Switch Configuration for more details.

Unlike OID query requests of OID_SWITCH_PORT_PROPERTY_ENUM, the extension does not have to call any ReferenceSwitchXxx or DereferenceSwitchXxx functions when it issues the OID_SWITCH_PROPERTY_ENUM request down the extensible switch driver stack.

Note  If the extension receives the OID method request of OID_SWITCH_PROPERTY_ENUM, it must not complete the OID request. Instead, it must call NdisFOidRequest to forward the OID request down the extensible switch driver stack.

Return Status Codes

The underlying miniport edge of the extensible switch completes the OID query request of OID_SWITCH_PROPERTY_ENUM and returns one of the following status codes.

Status CodeDescription

NDIS_STATUS_SUCCESS

The OID request completed successfully.

NDIS_STATUS_INVALID_LENGTH

The length of the information buffer is too small to return the NDIS_SWITCH_PROPERTY_ENUM_PARAMETERS structure and its array of NDIS_SWITCH_PROPERTY_ENUM_INFO elements. The underlying miniport edge of the extensible switch sets the DATA.METHOD_INFORMATION.BytesNeeded member in the NDIS_OID_REQUEST structure to the minimum buffer size that is required.

NDIS_STATUS_FAILURE

The request failed for other reasons.

 

Requirements

Version

Supported in NDIS 6.30 and later.
