With free-bsd machines it is only possible to use single-tagged vlans. This problem exsits in all Free-BSD releases. >How-To-Repeat: theoretical example: ifconfig vlan1 create ifconfig vlan1 vlan 1 vlandev fxp0 ifconfig vlan2 create ifconfig vlan2 vlan 2 vlandev vlan 1 >Fix: we thing if_vlan.c should be modified to accept creation of double vlans and to deny creation of tripple, quad tagged vlans.... >Release-Note: >Audit-Trail: >Unformatted:
