Hello,

I've got two ethernet cards Intel PRO/1000 QP (82571EB) and Intel
PRO/1000 QP (82575GB) in one router/firewall. I use OpenBSD 4.8 on
this box. That works fine, but I see some input "Ierr" on the interfaces
(using netstat), even when the load is not very high.

$ netstat -I em2 -w2 (bandwith = 150 Mbits)
em2 in
packets errs
43263 0
43458 17
39056 0
46648 124
44783 630
42571 0
45338 0
40932 33
43713 84
40193 193
40491 0

I would like to know if under FreeBSD, you see this kind of Ierr?

Thanks, regards.

what does
sysctl -a dev.em
show for the two cards and what version of FreeBSD are you using ?

On my RELENG_8 box anywhere from 150-200Mb. Its an i7 920 with HT
disabled. I get the odd error when traffic might burst to ~300Mb, or if
its a high pps DDoS

Thanks to all, I think I should have a try with FreeBSD so.

Make sure you try under freebsd 8.2 as the igb driver was improved, as
pointed out by Jack Vogel from Intel.
