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 eth-
       ernet 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  con-
              vention 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 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.
