RHCE:配置链路聚合Teamd可以使用的配置选项：
Broadcast:传输来自所有端口的每个包
Roundrobin:以轮循的方式传输来自每个端口的包
Activebackup:监视链路更改并选择活动端口进行数据传输
Loadbalance:监视流量并使用HASH函数以负载均衡的方式来进行数据传输
Lacp:这个需要交换机支持
添加网络组：
[root@foundation0 ~]# nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}'
Connection 'team0' (5d339c44-9c06-4a73-91d6-b8596458e1ca) successfully added.
为网络组team0添加IPV4地址：
[root@foundation0 ~]# nmcli connection modify team0 ipv4.addresses "192.168.2.69/16"
[root@foundation0 ~]# nmcli connection modify team0 ipv4.method manual
[root@foundation0 ~]# nmcli connection down team0
[root@foundation0 ~]# nmcli connection up team0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/15)
为网络组端口team0添加网卡接口：
为team0网络组添加网卡接口：
[root@foundation0 ~]# nmcli connection add type team-slave ifname eno67109424 master team0
Connection 'team-slave-eno67109424' (4eb2f5bf-bc26-41a3-b962-4cf1a3067c92) successfully added.
[root@foundation0 ~]# nmcli connection add type team-slave ifname eno83886648 master team0
Connection 'team-slave-eno83886648' (c292c983-6a3b-4ce4-a8cf-01e9931e437f) successfully added.
查看创建后的配置:
[root@foundation0 ~]# nmcli connection show

启用team0接口
[root@foundation0 ~]# nmcli connection up team0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/18)
查看team0是否配置成功：
[root@foundation0 ~]# nmcli connection show team0

6: eno83886648: up 1000Mbit FD
网络组接口有配置IP地址，而网络组下面的端口没有配置IP地址：
[root@foundation0 ~]# ip addr show eno67109424

如果team0修改配置后，端口网卡的配置也要重新配置
修改teamd的运行模式： 将activebackup修改成roundrobin
方法一：修改配置文件：
[root@foundation0 ~]# nmcli device disconnect team0 #停止team0
[root@foundation0 ~]# vim /etc/sysconfig/network-scripts/ifcfg-team0 #修改网卡配置文件
DEVICE=team0
TEAM_CONFIG="{\"runner\":{\"name\":\"roundrobin\"}}" #将activebackup修改成roundrobin
DEVICETYPE=Team
BOOTPROTO=none
DEFROUTE=yes
[root@foundation0 ~]# nmcli connection load /etc/sysconfig/network-scripts/ifcfg-team0 #重新加载配置文件
重新激活网络组配置文件:
[root@foundation0 ~]# nmcli connection up team0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/24)
重新激活端口配置文件：
[root@foundation0 ~]# nmcli connection up team-slave-eno83886648
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/25)
[root@foundation0 ~]# nmcli connection up team-slave-eno67109424
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/26)
查看是否配置成功:
[root@foundation0 ~]# teamdctl team0 state
setup:

},
"eno83886648": {
"link_watch": {
"name": "ethtool"
}
}
},
"runner": {

}
}
查看使用teamnl 命令显示要调整的选项：
[root@foundation0 ~]# teamnl team0 options

priority (port:eno67109424) 0
user_linkup_enabled (port:eno67109424) false

enabled (port:eno83886648) true
mcast_rejoin_interval 0
mcast_rejoin_count 0
notify_peers_interval 0
notify_peers_count 0
mode roundrobin
方法二：通过命令来修改：
[root@foundation0 ~]# nmcli device disconnect team0 #先关闭接口后修改
[root@foundation0 ~]# nmcli connection modify team0 team.config '{"runner":{"name":"activebackup"}}' #将roundrobin修改成activebackup
查看配置文件是否修改成功

重新连接team0
[root@foundation0 ~]# nmcli connection up team0
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/27)
查看team0下面的端口，因修改了配置，所以，以前所有的端口都没有生效。
[root@foundation0 ~]# teamdctl team0 state
setup:
runner: activebackup
runner:

将team0下面的两个端口重新激活生效：
[root@foundation0 ~]# nmcli connection up team-slave-eno83886648
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/28)
[root@foundation0 ~]# nmcli connection up team-slave-eno67109424
