When I enable link a= ggregation using LACP mode on two ports of our card, I expected load to be b= alanced on two ports(both are up). But interestingly traffic is flowing on o= nly one interface.=20 If I administratively bring down the interface on which traffic is flowing, I= see lot of packet loss for about 30 secs, After that it picks up. I think this is not expected. Are there any known issues with FreeBsd 8.2 ? Thanks, Naresh.=
