My manually do you mean brctl etc. or ifup bond0?

When they system is booting does it even mention bond0 when starting network services?

As a sanity check the network service is set to start on boot right? Is networkmanager installed?

Hi

Thanks for your quickly replied, Please see my feedback words in blue

My manually do you mean brctl etc. or ifup bond0?

I meant command #service network restart

When they system is booting does it even mention bond0 when starting network services?

I used command ifconfig to checked only see eth0 & eth1 up, but didn't see bond0 up.

As a sanity check the network service is set to start on boot right? Is networkmanager installed?

networkmanager? I though when I installed Fedora 12 the networkmanager has been installed.

NetworkManager will be the default on fedora 12. Unfortunately it does things differently than the standard network service. Honestly without doing research I do not know how to configure bonded interfaces within NetworkManager.

If you chkconfig --list network it should show all levels off. If this machine is a server type system it may be worth while turning NetworkManager off and turning network on and then relying on the network-scripts alone. NetworkManager is more suited to desktops and laptops that use VPNs, wireless, ppp etc whose configs may change fairly frequently.
