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
