I have simple Flexible Netflow config on 7206 router:
flow exporter EXPORTER
transport udp 2055
flow monitor default
ip flow monitor default input
ip flow monitor default output
It worked good for some time. Then suddenly router stopped netflow export. `show flow exporter statistics` command shows constant values. Logs are clean. I have similar config on 3 Cisco 2811 routers, and it works well.
What can cause problem?
Router is Cisco 7206VXR NPE-G2, IOS is Advanced Security 12.4(15)T7.
