NetFlow and onePK interaction

Hi all,

It is possible or some way to create onePK applications on Nexus 3048 that interact with NetFlow to obtain network statistics?

Thank in advance,

Paulo Torres Gouveia

There isn't a native NetFlow API as of yet.  But you could use the VTY Service Set to run show commands over the onePK channel, parse them and do something with the stats.  The Datapath Service Set also gives you direct access to the traffic flowing through the switch, so you could take that traffic and perform the analysis you want similar to how NetFlow would do it.

Thank you for your reply, Joseph.

Do we have available the Datapath Service Set for Java? Or its only for C?

Natively, it's only available for C.  However, one of our DPSS Principal Engineers created a JNI-based abstraction for DPSS in Java.  It is completely unsupported, but you can download it and give it a try from http://www.marcuscom.com/downloads/BRKSDN-3014 .
