I configured NetFlow on Cat6500, but application shows only a few MBytes, whereas it should have been several GBytes. |

Cat6500 uses MSFC
only for the first packet, and the last packets are switched using PFC
(CEF
, dCEF
). To correct configure Netflow
export on the Cat6500, you must enable Netflow on the MSFC and on the PFC. In your configuration is only the MSFC-netfow enabled, and the majority of traffic (PFC-switched) is missed! Or the netflow data from the switch is not getting to the collector anymore. Check the devices, supervisor and MSFC for config changes. |
