>Description:
ifconfig vlan407
vlan407: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=3<RXCSUM,TXCSUM>
        ether 00:1b:21:45:da:b8
        inet I.N.E.T netmask 0xfffffff8 broadcast 77.93.52.7
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        vlan: 407 parent interface: igb0
ifconfig vlan408 create
ifconfig vlan408 inet S.O.M.E netmask 255.255.255.248 vlan 408 vlandev igb0
tell about error(sorry, do not save), but config is applyed

ifconfig vlan408
vlan408: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=3<RXCSUM,TXCSUM>
        ether 00:1b:21:45:da:b8
        inet 10.11.19.51 netmask 0xfffffff8 broadcast 10.11.19.55
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        vlan: 408 parent interface: igb0

Tcp dump shows that no traffic is seen on vlan408 and vlan407
