netflow on Cat6 and netflow collector

I have configured the netflow on our switches according to the configuration guide from cisco wensite, and this is my config:

mls netflow

mls flow ip interface-full

ip flow ingress layer2-switched vlan 25,48

mls nde sender version 5

interface Vlan25

ip address 10.122.25.15 255.255.255.0

ip flow ingress

ip route-cache flow

!

interface Vlan48

ip address 10.122.48.201 255.255.255.0

ip flow ingress

ip route-cache flow

ip flow-export source Vlan25

ip flow-export version 9

ip flow-export destination x.x.x.x 9991

I can find the data been collected by the server on which cisco Netflow Collector has been installed, and I can generate report, but only show us the simple result such as: source

Ip and destination IP.

If we change to generate report based on protocol, it always gave us error message: no protocol data from result file.
