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

C is correct : tested in lab command expert [Expert@FWR81:0]# ip link set eth0 addr 00:1C:29:12:34:56 After reboot return to the original MAC

C is right answer VALID IN LAB

The question with answer.

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... https://community.checkpoint.com/t5/Security-Gateways/Is-it-possible-to-change-an-interface-MAC-address/td-p/58453?lightbox-message-images-58453=1905i6A14857F5E1DA9B1

READ CAREFULLY, it says "using GAIA", The correct answer should be D

I think D, https://community.checkpoint.com/t5/Security-Gateways/Is-it-possible-to-change-an-interface-MAC-address/td-p/58453

absolute C is correct tested in lab

I think D is the answer, as the question is related to using GAIA....

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.

C ip link help Usage: ip link set DEVICE { up | down | arp { on | off } | dynamic { on | off } | multicast { on | off } | allmulticast { on | off } | promisc { on | off } | trailers { on | off } | txqueuelen PACKETS | name NEWNAME | address LLADDR | broadcast LLADDR | mtu MTU } ip link show [ DEVICE ]

Answer would be D

I think, D) is the correct answer. There is no command IP link in expert mode
