Enable NetFlow export on a Cisco router

Turn on NetFlow v9 export so Zynty can build traffic and conversation analysis for a router's interfaces.

What you'll need

  • Admin access to the device's CLI (console, SSH or Telnet)
  • The router already added in Zynty over SNMP or SSH
  • The collector's IP address

Enable flow capture on an interface

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

Point the export at your collector

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

Turn on the protocol in Zynty

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.
