網路群組team：是將多個網路卡聚合在一起，從而實現容錯和提高吞吐量
#1 建立網路群組介面
nmcli connection add type team con-name TEAMname ifname INTname [config JSON]
TEAMname 指定連接名，INname指定介面名，
JSON指定runner方式，格式為：'{" runner":{"name":"METHOD"}}'
METHOD 可以是broadcast、roundrobin、activebackup、loadbalance、lacp
（1）建立網路介面群組team0
[root@centos7 ~]# nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"loadbalance"}}'
Connection 'team0' (e70483a1 -2688-4eb2-9466-8e732360291d) successfully added.
（2）給網路組team0配置IP位址
[root@centos7 ~]# nmcli connection modify metham0
##[root@centos7 ~]# nmcli connection modify metham0 ipv4.methamodman ipv4.addresses 200.200.200.200/24 gw4 200.200.200.12 建立port介面（SLAVE）
既就是產生群組組成員的設定檔。 注意：這個設定檔和網卡設定檔是相互獨立的。 nmcli connection add type team-slave con-name SLAVEname ifname INname master TEAMnameSLAVEname 指定連線名，INTname指定網路介面名稱（相當於指定要加入網路群組的網路卡名）， TEAMnmae指定所屬網路群組。 若連接名稱不指定，預設為team-slave-IFACE建立介面群組
這裡使用ens34、ens38兩塊網路卡[root@centos7 ~]# nmcli connection add con-name team0-ens34 type team-slave ifname ens34 master team0#Connection 'team0-ens34' (a481fb6d-bf61-413d-a27-ens34' (a481fb6d-bf61-413d-a27-28721a ) successfully added.[root@centos7 ~]# nmcli connection add con-name team0-ens38 type team-slave ifname ens38 master team0Connection 'team0-ens38' (758d0e-162 -46b2-b539-1d853a45be6b) successfully added.##3 啟用網路群組
啟用網路群組：nmcli connection up team0
## 啟用網路群組：nmcli connection up team0 啟用網路群組：nmcli connection up team0 啟用網路群組：nmcli connection up team0啟用群組成員：nmcli connection up SLAVEname[root@centos7 ~]# nmcli connection up team0Connection successfully activated (master waiting for slaves) (D-Bus active path: / org/freedesktop/NetworkManager/ActiveConnection/20)[root@centos7 ~]# nmcli connection up team0-ens34

6 刪除網路群組
#（1）斷開連接[root@centos7 ~]# nmcli connection down team0
Connection 'team0' successfully deactivated (D- Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/7)
查看下狀態
#[root@centos7 ~]# teamdctl team0 state
Device "team0" does not exist
[root@centos7 ~]# nmcli connection show

可以看到已經關閉成功
（2）刪除TEAM群組成員
[root@centos7 ~]# nmcli connection delete team0-ens34
Connection 'team0-ens34' (a4816d-bf61-413d-a2c7-289966bee1a7) successffbleted.
