= Step 1 =
You can manually force the assignment from a network card to what device comes up as (eth0, eth1 ...), by changing the udev rules. You can manually edit this file:
This file maps the card with MAC 00:1d:60:b5:43:66 to eth0 and the card with 5c:d9:98:af:21:43 to eth1.
If you want to reverse the assignementsassignments, switch eth0 and eth1 at the end of the entries. Or delete one of the entries. = Step 2 = You may need to also edit this configuration file as well: /etc/sysconfig/network-scripts/ifcfg-eth0 if it has the MAC address for the device in it (e.g. in a variable called HWADDR). '''Example''' HWADDR=00:1d:60:b5:43:66 You will need to adjust the HWADDR to match the MAC address of the card you wish to make eth0. Note: if you wish to keep eth1 active, you may also have to edit ifcfg-ith1 as well.
These changes will only take effect after a rebootor a restart of the network services.
