I'm trying to configure Teaming with two NICs. I'm running CentOS 7.5.1804 on VMware Workstation 14.1.2.

Steps I have done:
1) added team interface with below command

[root@client1 ~]# nmcli c a type team ifname myteam1 con-name myteam1 config my.conf

Connection 'myteam1' (6d95c6a4-cde9-437f-81e2-6c2cc2c0064e) successfully added.

Content of my.conf file:

[root@client1 ~]# cat my.conf 

{

    "device":   "myteam1",

    "runner":   {"name": "activebackup"}

}

2) I have added 2 slave interfaces:

[root@client1 ~]# nmcli c a type ethernet ifname ens33 con-name myteam1_slave1 master myteam1 

Connection 'myteam1_slave1' (dd1d1bde-ff15-4d53-a174-96225e95f431) successfully added.

[root@client1 ~]# nmcli c a type ethernet ifname ens37 con-name myteam1_slave2 master myteam1 

Connection 'myteam1_slave2' (bcd1319c-cb9b-4290-87ab-ef35d2a127b7) successfully added.

3) Restarted network and NetworkManager services.
4) Checked the my team interface state:

[root@client1 ~]# teamdctl myteam1 state

setup:

  runner: activebackup

ports:

  ens33

    link watches:

      link summary: up

      instance[link_watch_0]:

        name: ethtool

        link: up

        down count: 0

  ens37

    link watches:

      link summary: up

      instance[link_watch_0]:

        name: ethtool

        link: up

        down count: 0

runner:

  active port: ens33

When I try to check connection everything is fine. But when I try to take down myteam1_slave1 (ens33) I am losing connectivity despite the fact that it switches runner active port to ens37.

Please assist!
