AiUInt32 ul_PayloadMode
Defines the Payload Mode, for data flow reduction. So you can specify up to which level the
data shall be stored in the data buffer. With this function you can define this level for each VL.
Using this mode you can see the traffic on the bus without monitoring and transferring the full
data load.
Value Description
FDX_PAYLOAD_FULL Frames will be stored with full payload in the Monitor buffer.
This means the full Ethernet (MAC) frame is available for the
application.
FDX_PAYLOAD_IP_EXT Only the Frame status header, the MAC- /IP- frame headers
plus 20 bytes of the IP-Payload will be stored in the
corresponding data buffer.
FDX_PAYLOAD_IP Only the Frame status header, the MAC- /IP- frame headers
will be stored in the corresponding data buffer.
FDX_PAYLOAD_MAC Only the Frame status header, the MAC- frame headers will
be stored in the corresponding data buffer.
FDX_PAYLOAD_DEFAULT use default Value
Note: If port oriented functions used only ul_PayloadMode = FDX_PAYLOAD_FULL is
possible.
AiUInt32 ul_TCBIndex
This value defines the Trigger Control Block (TCB) Index which is written to the Monitor Trigger
Index Word if a frame has been received for the given VL. A value of FFh disables any
modification of the Trigger Index Word if a frame for the given VL is received.
A value of 0, disables the complete Trigger Control Block Processing with reception of the
given VL.
Valid range is 0...FDh and FFh (FEh reserved for internal use, ASP).
