    Hi All,

    We've got a FreeBSD test box in house - that's hooked up to another FreeBSD
    box via a crossover cable on one port (em0) - and to a switch & small
    network on the other port (em1).

    netstat -i -b shows...

    "
    Name Mtu Network Address Ipkts Ierrs
    em0 1500 <Link#1> 00:07:e9:59:c1:11 42631375 0
    em0 1500 192.168.0.1/30 em0 206 -
    em1 1500 <Link#2> 00:02:b3:e8:ca:bf 5978522 11465

              Ibytes Opkts Oerrs Obytes Coll
    [em0] 1761716617 43032198 0 97470457 0
    [em0] 17336 3457943 - 1979378621 -
    [em1] 4135141601 5545022 0 1570455231 0
    "

    [Wrapped for sanity]

    The em1 interface is constantly clocking up 'Ierrs' - admittedly they are a
    very small percentage of the total packets on the interface, but never the
    less they clock up constantly...

    Is this likely to be something silly like 'cheap switch' (It's a DLink
    10/100 - nothing special).

    Is it normal to run a small % (i.e. <0.01) of errors? - I found the devtool
    'ifinfo' - but this just reports them as 'Input Errors' as well...

    I'm trying to get hold of a different brand switch etc. to try it with at
    the moment...

    Thanks for any input,

    -Karl
