[Linux] NIC Card Reorder on RedHat/ CentOS

      In some cases, we may clone a system for deploy a new system quickly, then encountered a problem on NIC order.

      Let's resolve this problem.


Edit this file:     

/etc/udev/rules.d/70-persistent-net.rules


The content of this file is shown below:
# PCI device 0x14e4:0x164c (bnx2) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="00:11:22:33:44:55", ATTR{type}=="1", KERNEL=="eth", NAME="eth0"

# PCI device 0x8086:0x10d6 (igb) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?", ATTR{address}=="aa:bb:cc:dd:ee:ff", ATTR{type}=="1", KERNEL=="eth", NAME="eth1"

Just set the device name as the output "ifconfig -a" accordingly.
