Same MAC addresses

Question

ZyXEL

Has anyone seen the same mac addresses on end network devices? I am told that they have seen it several times on Zyxel switches ...

Answer 1

It often happens on any D-Link, Acorp, 3COM, etc. class equipment. On network cards and D-Link access points even too often.

Answer 2

there are glitches. Once a batch of motherboards came to us with the same poppies on built-in network cards.

Answer 3

On many routers, you can change the MAC address using standard admin tools. It is unlikely that manufacturers will specifically set the same MAC addresses, but admins can do this without any problems, including on the network cards of your computer or laptop. So there is nothing surprising in this.

Answer 4

Out of the box - hardly. But on some devices, when flashing, there is a final stage - setting the MAC. She could have been forgotten.

Answer 5

I also met a similar situation with Intel network cards, one batch, I met at school ...
