[nsp] Why couldn't cflowd collect netflow data from 6509?

[Sam Munzani]

When we had it set to ver 8, I didn't collect any data. When switched to ver
7 it worked fine. My receiver is Cisco NFC.

Hi,


I set up net flow exporting on catalyst6509 of our network as below:

On layer 2 configuration prompt:

set mls 10.11.12.22 2056
set mls enable


and On layer3 configuration prompt:

ip flow-export source Loopback0
ip flow-export version 5
ip flow-export destination 10.11.12.22 2055 ( there is another cflowd run
and collect netflow data from a m160 box)

And, I set up cflowd on my linux box with file size 1GB and the number of
file is 20.

When exec 'tcpdump -n udp port 2056'  ,  it shows  catalyst 6509 is sending
udp packets to
udp port 2056 continuously.


I started cflowdmux and cflowd, but after about half an hour, the content of
cflowd files contains nothing.

 I changed NDE version to 8 the result remains the same.


Why? and how could I make it work?
