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  prior-
              ity  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 net-
              work-device will show only untagged(non-vlan) traffic, and dump-
              ing  the  vlan-devices  will only show traffic intended for that
              vlan, without the tags.
