I did some more testing, If i drop the tagging in the interfaces on the switch against the openbsd machine and use them as ordinary ports and assign an IP addr to trunk0 everything work fine. The switches has a vlan-trunk between them so that works as well. I unplugged the interfaces in trunk0 to test the connectivity between the switches and everything works. The problem seems to be when i attach a vlan to trunk0, the traffic don't go to trunk0. The vlan config works when I'm not using trunk(4), can this be a bug in trunk(4)? Any ideas?
