RHEL NIC missing

Posted on

Problem :

I have a RHEL server with 4 NICS. I bound eth2 and eth3 as bond0.

However, I don’t know how to unbind the two NICs, so I just deleted ifcfg-bond0. Then I entered service network restart, and after that, I’m unable to find eth3. It’s not loaded at all.

I’ve tried to reboot my server, but it’s still not working…

Solution :

Remove MASTER=bond0 from eth2/3 and also remove, also remove alias bond0 bonding from /etc/modprobe.conf

In your ifcfg-eth2 and ifcfg-eth3 files under /etc/sysconfig/network-scripts, remove these two lines:


Restart your network service and everything should be ok.

Dont forget to clean up, remove any line having a bond-related configuration in your /etc/modprobe.conf
