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

4.重启网络

systemctl restart network

 

注：Centos不支持vconfig，可以使用IP，nmcli，nmtui等命令
