Turn on NetFlow v9 export so Zynty can build traffic and conversation analysis for a router's interfaces.
Apply ingress and egress flow capture to each interface you want traffic visibility on, usually your WAN and core-facing interfaces rather than every access port.
configure terminal interface GigabitEthernet0/1 ip flow ingress ip flow egress exit
Set the destination and version. Zynty accepts NetFlow v5 and v9; v9 is recommended for its richer, template-based records.
ip flow-export destination 10.20.0.50 2055 ip flow-export version 9 ip flow-export source Loopback0 end write memory
Open the device's Protocols tab and confirm NetFlow shows as receiving records, it usually takes one to two export intervals (60-180 seconds) to appear.
