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.
udev is in control. You need a
/etc/udev/rules.d/70-persistent-net.rules like:
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:8b:02:81:f4:4a", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
Then I think you first restart udev then network.
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
