[c-nsp] Nexus 5596 architecture

[Jiri Prochazka]

John,

thank you for a reply. I am interrested in unicast traffic only, no L3, 
no QoS requirements, low-latency is not needed, 10G ports only. Switches 
would be used for a standard Internet traffic flows.

I am really interrested in these switches, but I don't want to buy a pig 
in a poke..



Regards,

Jiri Prochazka
