Hey Mark,
You can use "ip" tools to do the trick. For Ubuntu I wrote this upstart script that helps with it without touching udev. You can see it here: http://www1.ngtech.co.il/paste/1175/
You can run this function at runtime and it will change the interface name.
On CentOS you will need to find the right "spot" in boot to apply this link. Before NetworkManager and after udev.
All The Bests, Eliezer

All,
I am trying to understand better how you give an interface a more descriptive name and get it all working without a reboot, if possible.
We have 1G and 10G interfaces, and I’m trying to use names like 1G-internal, 1G-external, 10G-private, etc. When I boot up, it’s all fine, but if I add one I’m not sure if there is a way to avoid the reboot? For example, I added the 10G interface names this week.
Specifically, is there a way to change the network interface name you see in ifconfig and nmcli connection without rebooting CentOS 7?
I changed the name in network-scripts. I tried to restart NetworkManager.
I brought down the interface and tried to rename the file and bring it up again, but it still retains the previous run-time setting associated with the same UUID in the file.
Also I find that on all but one of the server on which I did this, I can restart NetworkManager, but network.service is failing to restart. Do I want both active? And if yes, is this indicative of a problem related to changing the interfaces that goes away (only) by rebooting? For some reason, after doing this on several systems, on only one I can restart network.service, but it also still shows the old interface name.
thanks, Mark
