Linux / Unix Command: vconfig
Command Library


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 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 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.


ip(8), ifconfig(8)
