The issue is that IEEE 802.1Q specifies that VLAN 0 is "reserved." FreeBSD honors this reservation because the implementation is standards compliant. However, in some instances it would be able to create interfaces on VLAN 0 (e.g., when wanting to use FreeBSD for a "reserved" purpose). I understand that standards compliance is the good default design here.=20 However, it would be great if there were a sysctl flag that could be set to allow interfaces on VLAN0. The default value could be for standards compli= ant behavior, thereby allowing users to enable VLAN 0 if desired and they know = what they are doing. --=20 You are receiving this mail because: You are the assignee for the bug.=
