实验环境：CentOS Linux release 7.6.1810 (Core)

配置bond0，mode 1

nmcli是必须开启NetworkManager的服务

1、# nmcli connection add con-name bond0 ifname bond0 type bond mode active-backup ip4 192.168.0.110/24 gw4 192.168.0.1 ipv4.dns 192.168.0.1 autoconnect yes ipv4.method manual

2、# nmcli connection add type bond-slave ifname ens39 master bond0

# nmcli connection add type bond-slave ifname ens40 master bond0

3、# nmcli connection up bond-slave-ens39

# nmcli connection up bond-slave-ens40

4、# nmcli connection show

5、查看bond是否配置成功

#ip addr

#cat /proc/net/bonding/bond0

6、测试断开其中一个网卡，是否正常

#nmcli connection down bond-slave-ens39

配置子接口，即端口是hybird或者trunk

例如vlan是772

1、# nmcli connection add con-name bond0 ifname bond0 type bond mode active-backup autoconnect yes

2、# nmcli connection add con-name bond0.772 ifname bond0.772 type vlan id 772 dev bond0 ip4 192.168.0.110 gw4 192.168.0.1 ipv4.dns 192.168.0.1 autoconnect yes ipv4.method manual

3、# nmcli connection add type bond-slave ifname ens39 master bond0

# nmcli connection add type bond-slave ifname ens40 master bond0

4、# systemctl restart network

5、查看是否配置成功

6、查看网卡配置文件信息
