vconfig - VLAN (802.1q) configuration program.
vconfig [lots of long options]
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 physi-
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.
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. Usu-
ally 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.
