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...

[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
