## NAME
       vconfig - VLAN (802.1q) configuration program.

## SYNOPSIS
       **vconfig** _[lots_ _of_ _long_ _options]_

## DESCRIPTION
       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.

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

### 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, eth‐
              ernet 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** **|** **DEV**___**PLUS**___**VID**___**NO**___**PAD**
              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 physi‐
              cal network device will be ignored.  Dumping the network-device  will  show  only  un‐
              tagged(non-vlan) traffic, and dumping the vlan-devices will only show traffic intended
              for that vlan, without the tags.
