Hi All,
I have a usage question about netcf. Why netcf can not rename a existing physical
interface dynamically by itself?
The name of a physical interface is determined by lower levels of the
operating system, and can't be modified by netcf. the configuration that
is setup by netcf can only reference an *existing* physical device name,
it can't rename it.
If you have any other method, please share to me, or can we add
support for it in netcf?
One source of information is here:
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterf...
(although that only completely applies to systems running recent
systemd, e.g. Fedora 20, but not to RHEL6 as you appear to be running)
There is a reference there of how to change an interface name in a
system that isn't using "predictable network interface names" (or
biosdevname, which was a short-lived alternative attempt at a solution
to the same problem): modify the file
/etc/udev/rules.d/70-persistent-net.rules. You'll need to reboot the
system for this to take effect.
