RE: Help needed - Cisco Netflow

Hi all, the LC on 12000 series is 12000-SIP-601 (engine 5) with multiple STM-1 SPA card. As far as I know the engine 5 card cannot do 450Kpps on netflow. Since the STM-1 is mainly for NB-AMR traffic (95%), do you recommend the sampled netflow instead? Does anyone aware of the sampled netflow accuracy?

During the high load period, it can reaches 450Kpps on a STM-1 link. The router platform is Cisco 12000 series, can the router generate 100% netflow data with such traffic load? Also can someone suggest a carrier class netflow collector for mobile service provider environment.
Just a quick note..
You may want to post the Line Cards they have...Distinct LC have distinct Netflow capabilities (and impact).
