5. Apply required filter.

6. Change the IP in filter of Node which is sending Netflow to Orion (Cisco/Juniper/Switch/Router) and apply.

ip.src == && udp.port == 2055


udp.port == 2055

7.  Click Apply.


You should be able to see traffic from the Nodes like Cflow (for Cisco ), flow for Juniper, or Sflow.

If you still do not see packet, check your device or network for further troubleshooting. This will confirm Orion is not receiving any packet hitting NTA default port 2055.
