What I did on couple of my CentOS boxes is: - use a bridge which is connected to the specific nic(will always look as up after boot) - Run a cron script that checks if the nic state is "NO-CARRIER" or other weird situations like no IP address and try to run ifdown X-nic and then ifup X-nic. Depends on the hardware and situation you might need to choose what fits youe environment as a solution instead of fixing the whole CentOS distro.

Power was lost long enough that UPS did not work. When power came back on the C7 box boots way faster than the switch and resulted in no network. power cycling the C7 box resulted in network. This even happened a second time. The only way to get the box back was to power cycle. the box is remote and no keyboard and mouse connected. Any thoughts on why the e1000e would not talk to the switch ? The switch is an unmanaged linksys - could not get the model. It auto negotiates to 1G/full. Thanks, for any thoughts.
