NetFlow Export For Public IP on Switch

Hi Kannan,

Your switch 3750E doesn't support NetFlow. What you can try is SPAN the internet traffic to a software netflow generator that can convert the monitored traffic to NetFlow data. This netflow generator will send to your NetFlow collector. Check

The ASR 1002 is very capable of exporting Netflow. The configuration guide (link) explains it in some detail.
