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

[Dan Lockwood]

I'm surfing through Software Advisor on CCO and do not see the Sup32
listed as an option.  Is it still too new?  Since it has a built in
MSFC2 can I assume that I has similar routing support, OSPF, etc to the
720?

Thanks,
Dan

The Sup2 with DFC's will only support the quoted (marketing math) 256Gb
if you have the fabric module installed.

Effectively the Sup2 and Sup32 are equivalent baring three things:

1)  The Sup2 does support the addition of the Switch Fabric Module
2)  The Sup2 has a PFC2 while the Sup32 has the PFC3B/BXL.
3)  The Sup2 has the option of the MSFC2 while the Sup32 includes a
MSFC2

Since the Sup2 without a fabric operates in the same mode as a Sup32, so
they both have the same throughput capability of (marketing math) 32Gb.
The primary functional difference is the features on the PFC, so I would
suggest looking into the PFC3B's feature set to see if that more aligns
with what you want to accomplish.
