pnic loadconf Command Example
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
(Master FPGA)
This address is mapped to the parameter Flow timeout (measured in
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
(Master FPGA)
This address is mapped to the parameter Flow length (measured in
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
(PCI-X FPGA)
This address is mapped to the parameter Burst size (measured in 32-bit
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
(PCI-X FPGA)
This address specifies the count in PCI-X clocks before the DMA buffer is
transferred to the host if the buffer contains less than the programmed
burst size.
