[c-nsp] Discussion with 6500/7600 Sup Modules

[Dan Lockwood]

Hi All,

We are in the process of purchasing several new 6500/7600 devices for a
network overhaul and I have a few questions about the practical
application of the different supervisors.  For core devices we want to
run the new SUP720, my confusion is for the access layer.  We have a
large campus and data center that will be upgraded.  The Sup1 is old and
I wont buy that.  That leaves me with the Sup2, Sup32 and 720.
According to Cisco the New Sup32 only supports 32Gb while the Sup2 /w
DFC supports 256Gb.  Is this correct or am I misunderstanding something?
So the two questions I'm struggling with are 1) should I push L3
capabilities to the access switches and 2) What supervisor/series of
line cards (2A, 32, 720) should I consider?

Any other important issues I have failed to consider?

Thanks,
Dan
