В новом поколении маршрутизаторов настройка netflow поменялась. Теперь это можно настроить через Flexible NetFlow и нужно вводить следующие команды:

flow record NFArecord
 match ipv4 protocol
 match ipv4 source address
 match ipv4 destination address
 match transport source-port
 match transport destination-port
 match application name
 match interface input
 collect interface output
 collect ipv4 source mask
 collect ipv4 destination prefix
 collect ipv4 destination mask
 collect counter bytes long
 collect counter packets long
 collect timestamp sys-uptime first
 collect timestamp sys-uptime last
