I currently have a CentOS 6.5 box with 4 NICs.
eth3 all come up fine, however when I bring
eth1 up with an IP address, even on it's own, it causes complete network loss.
If I remove the IP and bring
eth1 up with the other NICs it works fine. Then adding an IP and restarting network services causes the network to lose connection again and requires a console connection to bring the interface down.
Is there anything that can be causing this on this particular NIC?
Configs for each NIC as below:
DEVICE=eth0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=none HWADDR=3C:4A:92:11:11:11 IPADDR=192.168.228.225 PREFIX=24 GATEWAY=192.168.228.254 DNS1=192.168.224.201 IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=no NAME="Management"
