When using GAiA, it might be necessary to temporarily change the MAC address of the interface eth 0 to 00:0C:29:12:34:56. After restarting the network the old MAC address should be active. How do you configure this change?
A.
As expert user, issue these commands: # IP link set eth0 down # IP link set eth0 addr 00:0C:29:12:34:56 # IP link set eth0 up
B.
Edit the file /etc/sysconfig/netconf.C and put the new MAC address in the field (conf :(conns :(conn :hwaddr (ג€00:0C:29:12:34:56ג€)
C.
As expert user, issue the command: # IP link set eth0 addr 00:0C:29:12:34:56
D.
Open the WebUI, select Network > Connections > eth0. Place the new MAC address in the field Physical Address, and press Apply to save the settings.
To change the MAC in R80 it can be done in two ways
CLI: set interface eth0 mac-addr XX:XX:XX:XX:XX:XX
GAIA: Network Management -> Network Interface -> ethX -> Edit -> Ethernet -> Hardware Address
Exactly can not be D, this is not the path on the GUI...
The correct path is:
Network management > Network interface > select the interface > Edit...

I think D is not correct as it saves the change to the config. So after a restart it would come back with the new MAC not the old. In C the config change is not saved so it would revert back to the old value after restart.
