[c-nsp] WS-X6724-SFP and 7600 S Chassis with RSP720-3CXL

[Saku Ytti]

Sorry about this, didn't read very carefully, though you were
shopping for 1x10GE SPA, which case you'd be paying 10k more for ES20
which has 2x10GE (adding secon 1x10GE SPA in SIP would make it
more expensive than ES20.
However similar math is true for ES20 in 1GE's, it's cheaper
in high density compared to SIP600+SPAs.

And for your latest post, I personally don't see need for
deep buffers in core, but if you do, and vlan local signifance
is not an issue to you, I'd go with ES20.
