首先查看系统当前connection及device配置

[root@MiWiFi-R3-srv Desktop]# nmcli connection show

[root@MiWiFi-R3-srv Desktop]# nmcli device status

DEVICE TYPE STATE CONNECTION

eno16777736 ethernet disconnected --

eno33554992 ethernet disconnected --

lo loopback unmanaged --

[root@MiWiFi-R3-srv Desktop]#

创建teaming接口

#nmcli con add type team con-name myteam0 ifname team0 config '{ "runner": {"name": "loadbalance"}}'

配置team静态ip

#nmcli con mod myteam0 ipv4.addresses 192.168.31.108/24

#nmcli con mod myteam0 ipv4.gateway 192.168.31.1

#nmcli con mod myteam0 ipv4.method manual

添加eno16777736、eno33554992至myteam0中。

#nmcli con add type team-slave con-name myteam0-port1 ifname eno16777736 master myteam0

#nmcli con add type team-slave con-name myteam0-port2 ifname eno33554992 master myteam0

激活taaming接口

#nmcli con up myteam0
