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, 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 | 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 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.
