70-persistent-net.rules ignored on Centos 6.6

[midnightoil]

Because of some application SW licenses I need to pin 'eth0" and "eth1" to specific NICs. I've read countless forum postings but no joy.

Centos 6.6

Code: Select all

uname -a
Linux dvmon 3.10.80-1.el6.elrepo.i686 #1 SMP Sun Jun 7 08:15:14 EDT 2015 i686 i686 i386 GNU/Linux

As a test I edited /etc/udev/rules.d/70-persistent-net.rules even to change ethX to enX, so en0 and en1. After reboot ifconfig still reports eth0 and eth1.

The motherboard (Gigabyte H87N-WIFI) has a separate ethernet controller for each NIC and /var/log/messages shows that it is always the lowest numbered device/interface that is assigned as eth0.

Should this even work in Centos 6.6?

Setting log-priority to 'info' and running udevadm trigger doesn't show any hints... Any advice?
