NIC Teaming on CentOS 7 with nmcli
1、Teaming Daemon安装
为了使用teaming功能，首先必须安装teamd包，系统通常不会安装。使用如下命令进行安装。
#yum install teamd -y
2、nmcli配置teaming
首先查看系统当前connection及device配置
[[email protected] Desktop]# nmcli connection show
NAME UUID TYPE DEVICE
[[email protected] Desktop]# nmcli device status
DEVICE TYPE STATE CONNECTION
eno16777736 ethernet disconnected --
eno33554992 ethernet disconnected --
lo loopback unmanaged --
[[email protected] 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
检查配置
[[email protected] Desktop]# nmcli connection show
NAME UUID TYPE DEVICE
myteam0-port2 1a0f2bfd-cea1-4c7b-b2de-d34199b8561e 802-3-ethernet eno33554992
myteam0-port1 8e0c325c-d069-4014-bb75-1fa1f4674618 802-3-ethernet eno16777736
myteam0 e2976c8e-da7d-4901-88c6-db8a9913947c team team0
[[email protected] Desktop]# nmcli device status
DEVICE TYPE STATE CONNECTION
eno16777736 ethernet connected myteam0-port1
eno33554992 ethernet connected myteam0-port2
team0 team connected myteam0
lo loopback unmanaged --
[[email protected] Desktop]# ip a s

通过teamnl查看slave网卡状态
[[email protected] ~]# teamnl team0 ports

3、修改teaming配置
[[email protected] Desktop]#nmcli connection modify myteam0 team.config ‘{ "runner": {"name": "roundrobin"}}‘
需要重启下team0方可生效[[email protected] Desktop]# nmcli connection down myteam0
Connection ‘myteam0‘ successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/9)
[[email protected] Desktop]# nmcli connection show
