ATM_BLLI structure (ws2atm.h)
The ATM_BLLI structure is used to identify B-LLI information for an associated ATM socket.
Syntax
typedef struct {
DWORD Layer2Protocol;
DWORD Layer2UserSpecifiedProtocol;
DWORD Layer3Protocol;
DWORD Layer3UserSpecifiedProtocol;
DWORD Layer3IPI;
UCHAR SnapID[5];
} ATM_BLLI;
Members
Layer2Protocol
Identifies the layer-two protocol. Corresponds to the User information layer 2 protocol field in the B-LLI information element. A value of SAP_FIELD_ABSENT indicates that this field is not used, and a value of SAP_FIELD_ANY means wildcard.
Layer2UserSpecifiedProtocol
Identifies the user-specified layer-two protocol. Only used if the Layer2Protocol parameter is set to BLLI_L2_USER_SPECIFIED. The valid values range from zero–127. Corresponds to the User specified layer 2 protocol information field in the B-LLI information element.
Layer3Protocol
Identifies the layer-three protocol. Corresponds to the User information layer 3 protocol field in the B-LLI information element. A value of SAP_FIELD_ABSENT indicates that this field is not used, and a value of SAP_FIELD_ANY means wildcard.
Layer3UserSpecifiedProtocol
Identifies the user-specified layer-three protocol. Only used if the Layer3Protocol parameter is set to BLLI_L3_USER_SPECIFIED. The valid values range from zero–127. Corresponds to the User specified layer 3 protocol information field in the B-LLI information element.
Layer3IPI
Identifies the layer-three Initial Protocol Identifier. Only used if the Layer3Protocol parameter is set to BLLI_L3_ISO_TR9577. Corresponds to the ISO/IEC TR 9577 Initial Protocol Identifier field in the B-LLI information element.
SnapID[5]
Identifies the 802.1 SNAP identifier. Only used if the Layer3Protocol parameter is set to BLLI_L3_ISO_TR9577 and Layer3IPI is set to BLLI_L3_IPI_SNAP, indicating an IEEE 802.1 SNAP identifier. Corresponds to the OUI and PID fields in the B-LLI information element.
