centos7使用nmcli配置网卡聚合链路

1、CentOS 7 使用 nmcli 配置网卡聚合链路CentOS7 系列对多网卡的配置发生很大的改变， 以下以 基于 RECL-7.0 系列对 actviebackup 属性的配置笔记。rootserver0 # nmcli con show/ 蓝色粗体的网卡是本例配置的网卡NAME UUIDTYPE DEVICEEthernet connection 2 8afe67cc-20ef-4985-86c3-b8d3c9371fc9 ens34802-3-ethernetEthernet connection 30cf045a5-012c-46bd-9367-1139666871b5802-3-e
