Quickly creating VLANs?

[Miroslav Slavkov]

# ifconfig vlan100 create inet 1.2.3.4/24 vlan 100 vlandev xl0
# ifconfig vlan100
vlan100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 1.2.3.4 netmask 0xffffff00 broadcast 1.2.3.255
        ether 00:10:5a:48:ce:a4
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
        vlan: 100 parent interface: xl0

  Works for me, but if you put in the 'inet' if breaks.
  
  # ifconfig vlan600 create vlan 600 vlandev fxp1 inet 10.20.0.1/24
  ifconfig: inet: bad value
  
  
  man ifconfig:
    Since an interface can receive transmissions in differing
    protocols with different naming schemes, specifying the
    address family is recommended.
  
  either needs to be revised to:
    except when creating a vlan, 'cause that causes sh*t to break
  
  or, the ifconfig command needs to accept 'inet' when creating a vlan.
  
  
  Is inet inherited from the 'vlandev' and therefore redundant?
