NIC Teaming on CentOS 7 with nmcli

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

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

NAME UUID TYPE DEVICE

[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

检查配置

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

通过teamnl查看slave网卡状态

[root@miWiFi-R3-srv ~]# teamnl team0 ports

3、修改teaming配置

[root@miWiFi-R3-srv Desktop]#nmcli connection modify myTeam0 team.config '{ "runner": {"name": "roundrobin"}}'

需要重启下team0方可生效[root@miWiFi-R3-srv Desktop]# nmcli connection down myTeam0
