Invalid flow errors recorded in the NetFlow Analyzer may result when a flow duration exceeds the cache timeout values. This condition displays the following event in the Traffic Analyzer Events monitor:

NetFlow Receiver Service [Poller] detected long flow with duration 90s on <link>Node</link>

 

To resolve this error, the following lines must appear in the Flow Monitor section of the Configuration file for Flow Records on Cisco devices:

cache timeout inact 10

cache timeout act 5

For additional information, see Configuring Devices for Flow Collection in the online help.
