Recently, I had to copy the settings of one MikroTik router to another one and after I saved the settings to a file and populated them on the second, I noticed that mac addresses were also copied.
Therefore, we had to reset them to standard ones.
First, let’s see what the interface numbers are (I have ether1 for 0, ether2 for 1, etc.):
interface ethernet print
And reset their mac-addresses:
interface ethernet reset-mac-address 0 interface ethernet reset-mac-address 1 interface ethernet reset-mac-address 2 interface ethernet reset-mac-address 3 interface ethernet reset-mac-address 4
If you need to reset the mac of the wireless interface, then save the wireless settings to the file:
interface wireless export file wifibackup
Look at the wireless interfaces (I have one at number 0):
interface wireless print
Reset all settings including the mac address:
interface wireless reset-configuration 0
Restore the settings from the previously saved file (mac-address in this case will remain standard):
