I have a  few 9k's and are about to turn up Netflow and was curious about sampling rates. I have the following line cards A9K-8T-LA9K-MOD80-TR A9K-MOD160-TR Does it matter what RSP's I have? I have RSP-440's and RSP-880's? Is there a way to monitor...

If I have 2 10G links between ASR9k'  is it preferred to make them and L3 channel or two independent L3 interfaces? 

Is there a way to sort thru netflow on my asr9k for a specific host address? Will there be any impact? or just no big deal
