I believe it does 1G/10G on all ports.  Previous N5k models had
limitations in this area.

Mixing 1G and 10G on the same chassis is not generally a good idea
because you will end up dropping packets due to the speed differences
between the two media.

it doesn't work like that on these platforms.  You may run into issues
with oversubscription between the fabric extenders and the local switch
or between one local switch and another, but the switches themselves
should be able to handle line rate on all ports.

BTW, the N3000 series is a completely different internal architecture to
the N5K series.
