vconfig

VCONFIG(8)						      System Manager's Manual							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 (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 net-
	      work 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.

FILES

       /proc/net/vlan/config
       /proc/net/vlan/[vlan-device]

       ip(8), ifconfig(8)
