Hello @yeowkm99 ,

 

If you are going to configure netflow, I think it will have a low impact on performance because netflow packets can be processed on the NPU side. But if you are going to configure sFlow, it will probably have a high impact on performance because sFlow packets can be processed on the CPU instead of the NPU.
