OPERATOR ERROR Use ethertool or "service network restart" the ifconfig needs a real nic not a virtual nic that bonds two nic's. run 'service network restart' and watch the order that the interfaces come up, I think, once again I think that the ethX's need to be up prior to bond0 activating. ________________________________ From: William Reich <reich@xxxxxxxxxxx> To: General Red Hat Linux discussion list <redhat-list@xxxxxxxxxx> Sent: Wednesday, August 19, 2009 11:33:34 AM Subject: IP Bonding and ifconfig We have configured IP Bonding to use eth3 and eth4. The bonded network name is ... "bond0". Testing out the configuration, we use ifconfig to bring the networks up and down. When we bring down eth3 or eth4 with the ifconfig tool, and then bring them back up, we get the expected result. When we use the ifconfig tool to bring down the "bond0", we see the network(s) go down. But, when we try to bring "bond0" back up using the ifconfig tool, the network does not come up. No traffic flows. Is this an OS bug or operator error of some type ?
