Hey,
I posted about this before as it was a bug with the beta as well, but on my RB2011 the Switch 1 shows as type Unknown… Switch 2 shows as a Atheros 8227 …

Yep… thats what I see. I saw it in 6.2 beta’s but my last post someone said it was fixed… its still there.
It appears to have been fixed in routeros-mipsbe-6.3rc1.
+1 it has resolved my problem 
Thank you.
