I configured the jFlow sampling in Juniper MX480:

enter image description here

but in my receive data server, there is no data received:

and when I use Paessler Netflow Tester test it, there cannot use 14.224.224.253:

enter image description here

Whether should I stop some processes then I can use it to receive data?

and when I use Any IP with 50001 port, there get nothing data received.

I use wireshark capture the packages, do not get the udp:50001 data:

Is there any problem with the MX480's jflow configuration?

I do not find any MPC there.

and there shows nothing for checking accounting:

admin@MX-RE0> show services accounting status 

{master}
admin@MX-RE0> show services accounting flow 

{master}

  • What does show services accounting flow show you? Also, do you have any DPCs or does your MX only have MPCs installed? – Jordan Head Mar 23 '20 at 13:11
  • See my updated post, and I hear about version 5 do not need any MPC. – 244boy Mar 23 '20 at 14:18
  • One more question, is there a reason you're doing version 5? All of this processing will be done on the routing engine and depending on your sampling interval/run rate, put additional strain on it. Your other option is v9 or v10 (IPFIX) which is done directly on the cards themselves. I'll provide the answer you're looking for, I just wanted to make sure you were aware. – Jordan Head Mar 23 '20 at 15:10
