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/PredictableNetworkInterface... (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.
