Cisco ASR1002-X Netflow version 5 performance

[Josef Baloun]

Hello,

customer is asking me regarding 1:1 Netflow version 5 on ASR1002-X.

Is it fully supported?

Is there any known caveat?

I suspect it lowers stability of the system, and need to be sure.

Thank you,

Josef Baloun

Are you referring to the sampling ratio? 1:1 sampling is sending all traffic conversations for NetFlow analysis using sampling. This can result in an increase in CPU and memory utilization on the device - so if this is a traffic heavy network, 1:1 sampling is not recommended.
