This chapter lists the NTPL commands and parameters that were supported in the Green Bay 2 release but that are not supported for 4GA SmartNICs in the Link-Capture™ Software 12.8 release or that have changed for these SmartNICs. See DN-0449 for the complete NTPL syntax for 4GA SmartNICs in Link-Capture™ Software 12.8.
The TxIgnore and TxPort parameters will change the values of the corresponding bits in the standard packet descriptor of a captured file, but they will only have an affect if a Setup NTPL command points to the bits in question using the TxIgnorePos or the TxPortPos parameter, respectively.
The Decapsulate parameter is not supported.
Align is a new parameter for 4GA SmartNICs in the Link-Capture™ Software 12.8 release. Its default value is Packed. This means that per default frames are stored back-to-back in the host buffer with no padding in between, while in the Green Bay 2 release frames were always 8-byte aligned and zero-padded.
For NT200A02 SmartNICs running on a capture/replay image, the Retransmit command is not supported. It has been replaced by the Assign command using the DestinationPort parameter.
For other Napatech SmartNICs, the DestinationPort parameter of the Retransmit command cannot be set to multiple ports.
The Deduplication command is not supported. It has been replaced by the DeduplicationConfig command, the Assign command using a correlation key recipe, and the DeduplicationWindow parameter in the ntservice.ini file. This allows deduplication on traffic up to 2 x 100 Gbit/s at full wire speed and on specific types of traffic, using much larger packet windows, which makes the feature much more usable and effective.
The IPMatch parameter is not supported.
For the TupleSwap parameter the IPMatchFirst and IPMatchLast values are not supported.
If a hash mask is defined using the HashMask command, this must be done before the HashMode command.
The HashMask command must always appear before the corresponding HashMode command.
For the ClassifyUnmatched parameter the All value is not supported.
The ListType parameter is not supported.
The JumboFrame parameter is not supported.
For the Layer3Protocol parameter the IPX value is not supported.
For data tests the ByteStr32 data type is not supported for 4GA SmartNICs (see 32-Byte Strings); and data values and data masks are restricted for 4GA SmartNICs compared to Green Bay 2. Furthermore, some NTPL expressions from Green Bay 2 might have to be rewritten to better utilize the resources.
For error tests the FrameSmall, FrameLarge, DecodeError and InnerDecodeError values are not supported.
The IpChecksumError, UdpChecksumError and TcpChecksumError values are only supported for NT200A02, NT100A01 and NT50B01 SmartNICs running on test and measurement images.
