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 filter-
	      ing 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
	      dumping  the  vlan-devices  will only show traffic intended for
	      that vlan, without the tags.
