创建 team0 设备和 team0 会话

向team0中添加从设备（ens224、256）

[root@xixi ~]# nmcli connection add type team-slave ifname ens224 con-name team0-port1 master team0
Connection 'team0-port1' (3c198f30-556c-407d-8a58-1c7e123b4791) successfully added.
[root@xixi ~]# nmcli connection add type team-slave ifname ens256 con-name team0-port2 master team0
Connection 'team0-port2' (cd8f75d6-e16a-402e-a651-a8d964683282) successfully added.

先激活 team0-port1、team0-port2 从设备，再激活 team0 主设备

[root@xixi ~]# nmcli connection up team0-port1
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/11)
[root@xixi ~]# nmcli connection up team0-port2
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/12)
[root@xixi ~]# nmcli connection up team0
Connection successfully activated (master waiting for slaves) (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/13)

[root@xixi ~]# nmcli connection show

查看 team0 的工作状态

[root@xixi ~]# teamdctl team0 stat
setup:
runner: activebackup
ports:
ens224
link watches:
link summary: up
instance[link_watch_0]:
name: ethtool
link: up
down count: 0
ens256
link watches:
link summary: up
instance[link_watch_0]:

link: up
down count: 0
runner:
active port: ens224

7: team0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

当从设备 team0-port1 （ens224）断开时，会切换到 ens256

[root@xixi ~]# nmcli connection down team0-port1
Connection 'team0-port1' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/14)
[root@xixi ~]# teamdctl team0 stat
