NFC Netflow Collector does not collect flows


Check with a sniffer tool if the NetFlow Collection Engine (NFC) router is sending flows to the NFC Collector, as shown:

  # snoop 9999
  If the packet capture is not showing any neflow packets, check the netflow statistics 
  and configuration on the NFC router: 
  # show ip cache flow

Make sure the ip flow-export command has been issued on NFC router.

For more information and examples of Netflow configurations, refer to Configuring Netflow.

If the packet capture shows Netflow packets but the collector is not collecting any flows, perform the steps in the Solving CNS NetFlow Collection Engine Problems section of Troubleshooting CNS NetFlow Collection Engine.
