Flexible Netflow/NEtflow Monitor can not be applied under interface after IOS upgrade

[gabor_fejer]

Hello All,

Just over the IOS upgrade from 152-1.SY5  to .155-1.SY6 on a cisco 6880-X box, but the old netflow commands seem to be not working anymore. Any idea how to apply netflow ? I don't understand this beaviour.

Thanks in advance!

(config-if)# ip flow monitor IPv4-FlowMonitor input

Look at the syntax changed :
