[c-nsp] Switch recommendation

[Michael K. Smith - Adhost]

The 4500 series will handle 32k Mac addresses if I remember correctly.  I
would recommend the WS-X4306-GB 6 port card.  It's non-blocking and can
handle jumbo frames on all ports.  If you just want to switch then the Sup
2+ will probably do what you need.  Then you could consider Sup redundancy
with the 4507 chassis...

Also, I would concur with others' comments about broadcast domains.  2
VLAN's with 20k hosts is a recipe for disaster regardless of the switch.

A handful. Today 2, tomorrow maybe 10?
