How much bandwidth does Netflow use to collect data from remote routers/switches? Netflow admin guide does not give much detail on how much bandwidth and min/max bandwidth recommendation.
Thanks!!
This will be highly dependent on the number of conversations that are being summarized by Netflow. Luckily its just a summary and carries no actual payload. Each UDP datagram carries information for many flows as well. Netflow v5 is 30 flows per datagram in right around 1500 byte packets. I can say that in all the customer environments I have seen, the amount is not substantial.
