1、安装vlan软件包

sudo apt-get install vlan

2、加载8021q模块

sudo modprobe 8021q

sudo sh -c 'grep -q 8021q /etc/modules || echo 8021q >> /etc/modules'

3、配置vlan子接口

sudo cat /etc/network/interfaces

auto em1.12

iface em1.12 inet static

address 120.52.139.9

netmask 255.255.255.240

gateway 120.52.139.1

auto em1.13

iface em1.13 inet static

address 123.58.236.26

netmask 255.255.255.248

auto em1.16

iface em1.16 inet static

address 223.71.150.91

netmask 255.255.255.248

4、激活vlan子接口

sudo ifup em1 12

sudo ifup em1.13

sudo ifup em1.16

5、重启网络服务
