This directive is used to assign a MAC address to an interface, overriding the one assigned to the physical NIC, This directive should not be used in conjunction with HWADDR. is the hardware address of the Ethernet device in the form AA:BB:CC:DD:EE:FF. This directive is useful for machines with multiple NICs to ensure that the interfaces are assigned to the correct device names regardless of the configured load order for each NIC's module, This directive should not be used in conjunction with MACADDR.

Linux set mac address how to#
How to assign a permanent MAC address to the bonding interface in RHEL ?.The Network Interface MAC address is changing after each reboot.Stay tuned with It’s FOSS for more Linux tutorial and tips. You have successfully changed the MAC address in true Linux style. Now, verify new MAC address: ip link show enp0s31f6 Next, set the new MAC using command: sudo ip link set dev enp0s31f6 address XX:XX:XX:XX:XX:XXįinally, turn the network back on with this command: sudo ip link set dev enp0s31f6 up I would recommend using Macchanger but if you don’t want to use it, there is another way to change the MAC address in Linux.įirst, turn off the network card using command: sudo ip link set dev enp0s31f6 down Restart your network manager and the associated network interface. sudo macchanger -r wlp2s0b1 Change MAC Address in Linux 4.
