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 physical lan.
add [interface-name] [vlan-id]
Creates a vlan-device on [interface-name]. The resulting
vlan-device will be called according to the nameing convention
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 |
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.
