Netflow shows double the bandwidth on link

Jump to solution

Hello,

We're installing Cisco 4331 series routers at a couple of our remote sites.  Each Router has 8 T1s in a Multilink.  In NPM the available bandwidth shows 12.288Mbps.  When I do stress testing NPM shows utilization is 12.288Mbps.  When I check Netflow Traffic Analyzer during the stress test it shows utilization of 23.9Mbps.  I am currently at a loss as to why there is a difference with NTA.  Anyone have any idea what could be happening?

Thank you

Hi,

Please ensure that you have configured only the command 'ip flow ingress' or 'ip flow egress' on the interfaces if you use both of them the traffic gets duplicated.
