[c-nsp] Is the Nexus 3064PQ usable ?

[Dan Brisson]

We had this same question about 3 years back and I'm not sure that 
anything has changed, but take this for what it's worth.  The Nexus 5k 
line uses cut-through switching where your traditional catalyst line 
switches are store and forward.  Here's a good link on this topic:

http://www.cisco.com/c/en/us/products/collateral/switches/nexus-5020-switch/white_paper_c11-465436.html

Also, the Nexus line may not have features that you want in a campus, 
such as layer 2 protections like dhcp snooping, DAI, etc...  That said, 
just make sure you know what features you need, including IPv6 features, 
which without verifying, I'm guessing are more plentiful in the Catalyst 
line.

Hope that helps.
