Enable Traffic-Flow on the router as:
[admin@MikroTik] ip traffic-flow> set enabled=yes [admin@MikroTik] ip traffic-flow> print enabled: yes interfaces: all cache-entries: 1k active-flow-timeout: 30m inactive-flow-timeout: 15s [admin@MikroTik] ip traffic-flow>
2. Specify IP address and port of the host, which will receive Traffic-Flow packets:
[admin@MikroTik] ip traffic-flow target> add dst-address=192.168.0.2 port=2055 version=9 [admin@MikroTik] ip traffic-flow target> print Flags: X - disabled # SRC-ADDRESS DST-ADDRESS PORT VERSION 0 0.0.0.0 192.168.0.2 2055 9 [admin@MikroTik] ip traffic-flow target>
Now the router starts to send packets with Traffic-Flow information.
