VLAN 1 on Cisco is their default VLAN, thus only untagged frames will be processed (I believe). Your OpenBSD box creates Tagged frames on VLAN 1 so it doesn't work. You could use assigned the IP address to the interface on top of creating subinterfaces (VLANs), then it should work as the non-vlan interface would send untagged packets. Am I Correct?

I have set up a dot1q trunk between a Cisco switch and an OpenBSD 3.1 box. Everything works beautifully except of VLAN 1 which is default Native VLAN on the Cisco switch. I am not able to see traffic on this interface on the BSD box until I change Native VLAN on the switch to something else. This of course solves the problem, but I am just curious - is this correct behaviour ?? I know that Native VLAN is untagged, but if I connect a Cisco router instead of the BSD box, Also VLAN 1 (native vlan) is reachable via a VLAN-subinterface on the router.... (And I do of course see the traffic on the physical interface. it is just that i want it to go to the vlan-interface :-) Best regards, Johan -------------- next part -------------- An HTML attachment was scrubbed...
