these are 3 diferent router, the First Router was x86, second and third are CCR 1016, recently i just notice from ether1 to ether 10 all mac address was Same on the 3 router.
how wonder why this can happen? anybody has a clue? and how to make them not same again?
Thanks
is it possible that you have used system backup tool to copy config from one to another, because, when you do that it also clones the Mac adresses, under the ethernet interface, just hit the “reset Mac-adress” button and that should clear it
probably because you restored the same backup file on the three device.
look at interface property and click on reset mac, or via console “/interface ethernet reset-mac-address”
My guess would be imported config script.
You have a Reset MAC address button in interface windows. Click it and it should revert back to original (unimported) MAC.
You can check aginst label on Routerboard hardware. It should be the same.
Also check Bridges (admin mac). And change it accordingly. Same MAC on different devices will break your network!
