NetFlow counting traffic by source and destination

[basbulg]

Howdy!

Is there a way to configure NetFlow so that it counts traffic (bytes and packets) entering an interface only if the traffic IP source/destination match an access-list?

Edit: typo

@basbulg yes you can use an access-list to match the traffic to be sent to the netflow connector.

never tried this - this required testing by reversing the ACL.
