Has anyone ever run all 3 FCC ports at the same time with a 100Mbit link? I think I'm seeing the Communications Processor get overloaded, but Motorola claims there is no problem. The setup is as follows: FCC1 is ftp-ing a very large file out (say 100MBytes). FCC2 is ftp-ing a very large file in. FCC3 is being pinged at maximum rate by a PC. What happens occasionally (like 1 out of 10 times) is that the ping on FCC3 is not responded to in any manner. A close examination of the Ethernet PHY (AM79C874) indicates no errors, but the MAC is reporting CRC errors. I have captured the MAC --> PHY transfers on a logic analyzer and am decoding them at present (I hate computing a CRC-32 by hand). I was hoping someone else has experience relative to this situation.
