[c-nsp] Catalyst 3850 10G version experiences

[Robert Hass]

Hi
I'm building mid-large campus network with 3000 access ports.

Is it good idea to use stack of two 3850-XS units as core/aggregation layer
? I'm planning to use 2 or 4 Catalyst 3850-24SX in stack.

They're quite fresh products - released Mid 2015. So their maturity is
questionable...
Maybe I shoud choose something proven in field like Catalyst 4500-X.
Also I'm afraid about small buffers on 3850XS.
