Unhappy NIC_teaming working only on primary Ethernet port - RHEL 7.6


Hi everyone,

i have configured nic teaming on rhel 7.6 server,"teamdcl team0 stat" showing both configured port up, when i down primary port its switch to next active port but i am not able to ping or access ip through slave port but when i up the primary port and switch team to primary port its working fine also i configured nic with bond module, i am facing same issue does anyone know what could be issue or what i am missing here, i am using Oracle Virtualbox Guest VM RHEL 7.6.

Regards,
Pravin Goud

It will help if you posted your config files...
What is in dmesg (or messages) when you down the primary port?

Please check below cofiguration

[root@node1 ~]# teamdctl team0 stat

[root@node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-team0

DEVICE=enp0s9
ONBOOT=yes
TEAM_MASTER=team0
DEVICETYPE=TeamPort
[root@node1 ~]#


When i down enp0s8 team switch to enp0s9 but ping dosent work, but when i up the enp0s8 port and switch same port on team i can access or ping the machine thats mean teaming only working on Primary connection (enp0s8).
