1.添加模块

modprobe --first-time 8021q

查询模块状态

modinfo 8021q

2.创建VLAN配置文件

cd /etc/sysconfig/network-scripts

cat ifcfg-eth0.10

DEVICE=ethX.10

BOOTPROTO=none

ONBOOT=yes

IPADDR=192.168.48.211

PREFIX=24

NETWORK=192.168.48.0

VLAN=yes

3.创建VLAN网卡

ip link add link eth0 name eth0.10 type vlan id 10
