1.
team也是链路聚合的一种方式
最多支持8块网卡
支持模式
广播
论旬
主备
负载均衡
2.配置
nmcli connection add con-name team0 ifname team0 type team config ‘{"runner":{"name":"activebackup"}}‘ ip4 172.25.254.100/24
nmcli connection add con-name eth0 ifname eth0 type team-slave master team0
nmcli connection add con-name eth1 ifname eth1 type team-slave master team0
3.测试
watch -n 1 teamdctl team0 stat
ifconfig eth0 down
ifconfig eth0 up
