            Bug ID: 225362
           Summary: Creating VLAN
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: vermaden at interia.pl

Look at this command:

# ifconfig em0.4 create vlan 2 vlandev em0 inet 10.0.0.1/24

Theoretically it should create interface 'em0.4' with VLAN '2', but it creates
interface 'em0.4' with VLAN '4'.

# ifconfig em0.4
em0.4: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=103<RXCSUM,TXCSUM,TSO4>
        ether xx:xx:xx:xx:xx:xx
        inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255 
        inet6 fe80::f2de:f1ff:febd:51ae%em0.4 prefixlen 64 scopeid 0x6 
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: no carrier
        vlan: 4 vlanpcp: 0 parent interface: em0
        groups: vlan 

Is that a bug?

Regards.
