Re: [IPFIX] IPFIX / Netflow

Thanks Paul,

This really simplifies things here. Now we're certainly about what we can develop or use on ways to maintain compatibility between IPFIX and NFv9 standards.

Juarez,

Why do ipfix implementations such as vermont, maji, YAF(silk) just
export ipfix messages and not netflow v9 messages?

Is there some legal restrictions with cisco?

No. While Cisco holds patents pertaining to NFv9 export, we allow that:

 "If any claims of any issued Cisco patents are necessary for
  implementing this specification, any party will have the right to use
  any such patent claims under reasonable, non-discriminatory terms,
  with reciprocity, to implement and fully comply with the
  specification."
