I assumed since he was asking about a "top of rack" (TOR) switch, he was actually using it as a top of rack switch and adding a couple more uplinks to his core would be cheaper than replacing all the hardware. Not understanding the topology and the application makes good recommendations a crap shoot, at best.

So as its not generally needed for the sort of things that tor switches are used for, its not added to the hardware spec. Nick
