[c-nsp] Cisco noob -- design guidance request

[David L. West]

Thanks. I think I screwed up buying the hardware though. I have a 2960G-24TC 
as the core switch in the server room, a 2960-48TT for the first floor, and 
a 3548XL for the 3rd. Only the last is Layer 3.

Reading your message and doing further research I begin to suspect I have to 
have Layer 3 switches throughout for this all to work.
