VCONFIG(8)                                                          VCONFIG(8)



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,  ethernet  header  reorders  are turned on. Dumping the device will appear as a common ethernet
              device without vlans. When 0(default) 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 par-
              ticular 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.
