We are using a Cisco Catalyst 5513 with a NFFC II Engine and enabled
NetFlow exports on both!

Could it be the problem that the switch caches some information without
letting the RSM know about the packets (just switches the packet with the
information inside its cache)?

Our thoughts are based on this:

We could only account packets if the RSM is used to make a routing
decicion and the packet crosses a vlan border - correct?

Thank you!
