Usage Information

The syntax of such parameter files is (address) value where address is the decimal address of the DPI control register, and value is the hexadecimal parameter to be loaded. Table 27 shows the parameters to which each address is mapped.

Table 26 pnic loadconf Address Mapping

Address Corresponding Parameter

Address 20 This address is mapped to the parameter Flow timeout (measured in (Master FPGA) multiples of 0.86 seconds). This parameter controls how quickly the stateful packet analysis can garbage-collect previous states. Smaller

values increase the number of concurrent flows that can be tracked. The default value is 16.

Address 16 This address is mapped to the parameter Flow length (measured in (Master FPGA) packets). This parameter controls the maximum number of packets in a

flow that are considered for capturing. Typical values range from 6 to16.

Address 24 This address is mapped to the parameter Burst size (measured in 32-bit (PCI-X FPGA) words). This parameter sets the number of 32-bit words to transfer in one

PCI-X master cycle. Larger bursts achieve higher throughput but may increase buffering latency and contention with other devices sharing the same bus. The default value is 1024.

Address 36 This address specifies the count in PCI-X clocks before the DMA buffer is (PCI-X FPGA) transferred to the host if the buffer contains less than the programmed

burst size.
