(BSD) that has been in use since the development of the PLC-5
Ethernet over eight years ago. This stack was also ported over to the
legacy Ethernet products to let us take advantage of any bug fixes we
did not pickup over the years, enhanced UDP message support and the
ability to do super-netting.
• Addition of Connection Count Added to Diagnostics (OS501 only)
The diagnostic sub-segment in the dualport was modified to contain a
count of the total ethernet connections, the inbound connections and
the outbound connections. This data is transferred to the ethernet
channel diagnostic file (if of sufficient length) during the motherboard
housekeeping. The counts are available at word 50 (total), 51 (inbound)
and 52 (outbound) in the diagnostic file for the ethernet channel.
• Addition of IBD (I Be Dead) Data Added to Diagnostics (OS501 only)
The diagnostic sub-segment in the dualport was modified to contain
IBD data upon crash of the daughtercard. If the crash occurs after
communication with the motherboard is established, this data is
transferred to the ethernet channel diagnostic file (if of sufficient length)
during the motherboard housekeeping. The data contains register, stack,
address, traceback and error information about the crash. The data
starts at word offset 5 of the diagnostic file. This will allow the IBD data
to be maintained in the diagnostic file over subsequent power-cycles,
allowing for support analysis.
• Memory Module Bootp problem (OS501 only)
Currently, there is a bug for the memory module. If S2:1/10 bit (Load
Memory Module on Memory Error Bit) is set, when processor has
hardware fault, program in memory module will be loaded into the
processor, the IP address in memory module will be applied with bootp
is disabled in the memory module. However, current processor applies
the IP address set by bootp under above situation.
