    Hi,

    I have a Cisco 2621xm and PIX 525 connected together. The Cisco 2621xm
    is my perimeter router and connects via fast ethernet port to my PIX's
    outside interface. I am getting CRC and input erros (no collisions) on
    the Cisco 2621xm but not on my PIX. We have replaced the cable, checked
    for EMI, but we are still getting these erros. When I do a show
    interface on my 2621xm this is what it looks like:

    FastEthernet0/1 is up, line protocol is up
    Hardware is AmdFE, address is 000f.24d5.3f61 (bia 000f.24d5.3f61)

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    This is what I get when I do a show interface on the PIX:

    interface ethernet0 "outside" is up, line protocol is up
    Hardware is i82559 ethernet, address is 0013.6031.c216

    0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
    394633441 packets output, 4227635261 bytes, 95085 underruns
    0 output errors, 0 collisions, 0 interface resets
    0 babbles, 0 late collisions, 0 deferred
    0 lost carrier, 0 no carrier
    input queue (curr/max blocks): hardware (128/128) software
    (0/81)
    output queue (curr/max blocks): hardware (0/89) software (0/1)

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Not sure what is wrong. I have read in some places that this is a
    warning that a hardware failure is possible in the near future. Has
    anyone else experienced this problem or does anyone have any
    suggestions?

    Thanks

    We did a few things steve. First of all we ran a totally different
    cable a totally differnt path. Second of all, we put a fluke network
    meter on there and it didn't find anything. Have you had this problem
    before and EMI was the resulting problem?

    Your input is appreciated.

    Thanks

    Adam
