Network connection show disconnect after configure Bonding


Hi All,

I have 4 network ports (eth0, eth1, eth2 and eth3), i configured eth0 and eth2 as Bonding, after configure and perform server restart find out network connection in GUI show connection disable, check on network connection in GUI both eht0 and eth1 is missing from network connection GUI. When i'm check using ifcfg -a command i can see bond0 and eth0 and eth2, the connection is up!!

May i know what wrong for the settings? How come when i check using command if show connection is up and i can ping this bonding connection but check using GUI i can't see eth0 and eth2, check taskbar it show connection are disconnected.

Please find below for my settings.

Based on your files, I'm guessing you have a RHEL-base OS. Centos?

What does ifcfg give you? Also, what GUI are you using?
