I have a simple question that might be easy to answer but if you have a supporting document please provide the link. The question is:
Is it recommended to have Netflow running permanently in a 6509 or is it a tool that needs to be enable only as needed (reactive troubleshooting)?
Planing on enabling it on our ISP port for traffic analysis using solarwinds, but unsure if it is a feature that should stay ON all the time since i think it may cause performance issues or increase CPU utilization in the switch. I may be wrong so any supportive information is welcome.
Thank you,
Francisco.
