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

好像还需要内核支持包转发功能吧？现在vlan间可以分配到不同网段的ip了，但是vlan间通信不能。

是的，配制三层VLAN－trunk

VLAN的配置不是只能在交换机上才行吗？
