CentOS7设置网卡子接口

作者:互联网

1.网卡上联到trunk端口

2.编辑网卡配置文件,cat /etc/sysconfig/network-scripts/ifcfg-eth0,内容如下:

# Generated by VMWare customization engine.
DEVICE=eth0
ONBOOT=yes

2.cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.202 #新建vlan202子接口文件

cat /etc/sysconfig/network-scripts/ifcfg-eth0.202,内容如下:

PHYSDEV=eth0
VLAN=YES
TYPE=Vlan
VLAN_ID=202
NAME=eth0.202
REORDER_HDR=yes
GVRP=no
MVRP=no
ONBOOT=yes
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
BOOTPROTO=none
IPADDR=10.10.202.13
NETMASK=255.255.255.0
GATEWAY=10.10.202.254

2.重启网卡服务,如果报错则 systemctl restart NetworkManager。如果之前该机器配置过网卡,则还要删掉默认路由,vim /etc/sysconfig/network 删除默认网关行
