centos7 team网卡绑定不生效
1.Teamd 查看状态不能发发现绑定端口Ens37ens38 网卡下有配置情况下，team0绑定后可以生效但是
使用teamdctlteam0 st查看不到端口具体信息
# teamdctl team0 st

runner: activebackup

2、esn37ens38 接口下有配置
删除端口配置
nmcliconndelteam0-port1
nmcliconndelteam0-port2
nmcliconndelens37
nmcliconndelens38
Nmcli con show
Ip addr
3、重新添加team-slave端口
添加team-slave 端口
Nmcli con add type teamcon-name team0-port1 ifname ens37 master team0
Nmcli con add type teamcon-name team0-port2 ifname ens38master team0
4、检查team0状态，状态正常
# teamdctl team0 st
setup:
runner: activebackup
ports:
ens37
link watches:
link summary: up
instance:
name: ethtool
link: up
down count: 0
ens38
link watches:
link summary: up
instance:
name: ethtool
link: up
down count: 0
runner:
active port: ens37
5、ifdown ens37端口
初始状态活动端口为ens37, 网络正常 ，关闭ens37端口，活动端口切换为ens38,ping丢包2个
# ifdown ifcfg-team0-port1
Device 'ens37' successfully disconnected.
# teamdctl team0 st
setup:
runner: activebackup
ports:
ens38
link watches:
link summary: up
instance:
name: ethtool
link: up
down count: 0
runner:
active port: ens38
#
6、ifupens37端口
Ping短暂中断，后面恢复正常active prots依然为ens38 ,没有发生抢占，非常OK
# teamdctl team0 st
setup:
runner: activebackup
ports:
ens38
link watches:
link summary: up
instance:
name: ethtool
link: up
down count: 0
ens37
link watches:
link summary: up
instance:

link: up
down count: 0
runner:
active port: ens38
