We just received our first rb816 and installed it on a rb600a router running RouterOS v3.30.
The MAC addresses are invalid and ports from switch1 & switch2 are using the same MAC addresses.
I upgraded to RouterOS v4.9 with no change. I also reset the configuration with the rb816 attached and also reset it with it not attached with no change to this issue.

Has anyone else seen this? I could manually enter the MAC addresses from the sticker on the bottom of the rb816, but I would prefer it to just work instead.
