I'm running FreeBSD 10.0-RELEASE-p1 on an ASRock C2550DI4 motherboard with two built-in Intel i210 NICs, which I've aggregated together with lagg(4). The NICs are connected to a HP 1810-8Gv2 switch, and the ports trunked together there.
/etc/rc.conf
However, when I started a
Interestingly, the individual interfaces (igb0 and igb1) don't show any errors. In addition, the switch reports that no packets have been received with an error either on the individual ports or the trunk. The switch also says that the ports are connected at 1000 Mbps/full duplex.
Since I can't find any indication of the errors in any of the system logs either, might anybody have a suggestion as to where I should go looking next? Maybe try some kernel tunables or other system utilities besides
Finally, for completeness sake, below are two Munin graphs showing that the errors go hand in hand with outbound lagg0 traffic.
