I have a qustion with regard to the difference between Jflow/Netflow v5 and v10.
I already know the basic differences:
-the record format of the "Netflow/Jflow" packets v5 are different from v10 so this might be already a first good point which differentiate the 2 version: v10 give more freedom in selecting which information we might want to sample (basically)
-v5 does not support IPv6
-for MX, v5 and v10 are only supported on MPC-3D line card
-v5 is based on rfc 3954
-v10 is based on RFC 7011, RFC 7012
So, assuming that I am only interested in IPv4 and I have an MX with line card MPC-3D I have than the freedom to implement the v5 or v10. what are the drawback in using sampling from the RouteEngine (v5) or from the Packet Forward Engine (v10, IPFIX) in terms of "cpu´s" load or other resurces limitation which could impact the normal forwarding of the production traffic?
Here are my views regarding your query.
RE based sampling limitations:
PFE based or inline sampling restrictions and limitations:
The following considerations apply to the inline flow-monitoring instance configuration:

Thank you for your contribution on my question. I did not have enough time to go through this topic during the last months in any case I appreciate your effort on this.
>>You can configure only one type of sampling–either PIC-based sampling or inline sampling–per family in a sampling instance. >>However, you can configure PIC-based and inline sampling for different families in a sampling instance.
-> Maybe it is a late question, but trying to understand the difference between PIC-based and inline.
Thanks in advance.
"Inline" - executed on Trio LU chip , or its equivalent (equivalent of separate LU chip in newer Trio single-chip versions). Can be done on any MPC linecard, no special separate HW is required. Requires license.
"PIC-based" - executed on Services card (MS-DPC, MS-MPC, MS-MIC). Special separate HW (MS-DPC, MS-MPC or MS-MIC) is required, license is required.
