The following example uses the native IOS command line interface to configure the SUP and MSFC modules of a 6500 series switch. This example is based on the Cisco documentation for Cat6500 w/ SUP2/720 running IOS 12.1. For further information, refer to http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.1E/native/configuration/guide/nde.pdf

At the switch level (SUP2)

mls netflow # Enables Netflow on the PFC

mls nde sender version 5 # Turns on Netflow, sets version

mls flow ip interface-full # Sets an appropriate flow mask

mls nde interface # Populates egress interface fields

mls aging normal 32 # Netflow inactive timeout in seconds

mls aging long 64 # Netflow active timeout in seconds

At the routing module (MSFC)

ip flow-export version 5 # Define Netflow version

ip flow-export destination 10.70.x.x 2055

ip flow-cache timeout inactive 15

On each interface that you want to monitor (for example interface gi 7/1)

ip route-cache flow

The commands listed above are done in Native IOS which you should be using from what you post as your IOS version. The first set of commands are run on the PFC, and the 2nd group are features of NetFlow that run at Layer 3 only.

The per-interface NDE feature allows you to enable or disable NetFlow collection on a per-interface basis for packets forwarded in hardware (PFC) or software (RP). This feature is automatically enabled in Release 12.2(33)SXH and later releases.

Check here as well and make sure you are using NetFlow correctly on your box, and your software meets the requirements of what you are trying to do.
