       vconfig - VLAN (802.1q) configuration program.


       vconfig [lots of long options]


       The  vconfig  program allows you to create and remove vlan-devices on a
       vlan enabled kernel. Vlan-devices are virtual  ethernet  devices  which
       represents the virtual lans on the physical lan.


       add [interface-name] [vlan-id]
              Creates   a   vlan-device  on  [interface-name].  The  resulting
              vlan-device will be called according to the  nameing  convention

       rem [vlan-device]
              Removes the named vlan-device.

       set_flag [vlan-device] 0 | 1
              When  1 (the default since 2.6.18), ethernet header reorders are
              turned on.  Dumping the device will appear as a common  ethernet
              device  without  vlans. When 0 however, ethernet headers are not
              reordered, which results in vlan tagged packets when dumping the
              device.  Usually  the default gives no problems, but some packet
              filtering programs might have problems with it.

       set_egress_map [vlan-device] [skb-priority] [vlan-qos]
              This flags that outbound packets with a particular  skb-priority
              should be tagged with the particular vlan priority vlan-qos. The
              default vlan priority is 0.

       set_ingress_map [vlan-device] [skb-priority] [vlan-qos]
              This  flags  that  inbound  packets  with  the  particular  vlan
              priority   vlan-qos   should   be   queued   with  a  particular
              skb-priority. The default skb-priority is 0.

       set_name_type VLAN_PLUS_VID |  VLAN_PLUS_VID_NO_PAD  |  DEV_PLUS_VID  |
              Sets  the way vlan-device names are created. Use vconfig without
              arguments to see the different formats.

       NOTES  VLAN will use Broadcom's NICE interface when the network  device
              supports  it.  This  is necessary, since usually the hardware of
              these devices already removes the vlan  tag  from  the  ethernet
              packet.  The  set_flag  option on vlan-devices created on such a
              physical  network  device  will   be   ignored.    Dumping   the
              network-device  will  show  only untagged(non-vlan) traffic, and
              dumping the vlan-devices will only  show  traffic  intended  for
              that vlan, without the tags.
