CentOS7配置双网卡绑定

配置team0配置文件：

[root@CentOS7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-team0
DEVICE=team0
DEVICETYPE=Team
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.1.71
PREFIX=24
GATEWAY=192.168.1.1
TEAM_CONFIG='{"runner": {"name": "activebackup"}, "link_watch": {"name": "ethtool"}}'

配置eno33554984 :

[root@CentOS7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno33554984
EEVICE=eno33554984
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 100}'

配置eno50332208 ：

[root@CentOS7 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno50332208
DEVICE=eno50332208
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 99}'

重启网络：

[root@CentOS7 network-scripts]# systemctl restart network

查看端口状态：

[root@CentOS7 network-scripts]# teamnl team0 ports
4: eno50332208: up 1000Mbit FD
3: eno33554984: up 1000Mbit FD

查看team状态：　　
[root@CentOS7 network-scripts]# teamdctl team0 state
setup:
　　runner: activebackup
ports:
　　eno50332208
　　　　link watches:
　　　　　　link summary: up
　　　　　　instance[link_watch_0]:
　　　　　　　　name: ethtool
　　　　　　　　link: up
　　　　　　　　down count: 0
　　eno33554984
　　　　link watches:
　　　　　　link summary: up
　　　　　　instance[link_watch_0]:
　　　　　　　　name: ethtool
　　　　　　　　link: up
　　　　　　　　down count: 0
runner:
　　active port: eno33554984

模拟网卡故障：

[root@CentOS7 ~]# ip link set eno33554984 down

查看team状态：
[root@CentOS7 ~]# teamdctl team0 state
setup:
　　runner: activebackup
ports:
　　eno33554984
　　　　link watches:
　　　　　　link summary: down
　　　　　　instance[link_watch_0]:
　　　　　　　　name: ethtool

　　　　　　　　down count: 1
　　eno50332208
　　　　link watches:
　　　　　　link summary: up
　　　　　　instance[link_watch_0]:
　　　　　　　　name: ethtool
　　　　　　　　link: up
　　　　　　　　down count: 0
runner:
　　active port: eno50332208
