Can you check > ifconfig dc0? Yes of course, I knew I would forget to send something: dc0: flags=8843 mtu 1500 inet 193.2.4.17 netmask 0xffffff00 broadcast 193.2.4.255 ether 00:00:f8:10:52:47 media: Ethernet autoselect (100baseTX ) status: active > > To have collisions, it must be running half-duplex.

The other end is a switch and it is on FDX, that is why these collisions are so curious. Switch doesn't see input errors, it does however see out errors. I tried explicitly setting dc0 to 100baseTX, full-duplex and collisions are still there. Also I tried setting this explicitly in SRM, but no change.
