Hi,

I have a 12M microwave link connected to cisco 2811 Fastethernet 0/1. The netflow graph sometimes shows peeks up to 75 to 100M which is a bit odd. The MRTG graph at the ISP side is showing the correct graph which is 12M maximum.

I checked the 5 minute input rate and 5 minute output rate on the router interface and they never exceeded 12M. other routers are displaying the bandwidth usage correctly.

netflow version I am using is 7.5 build 7500

any idea what could be wrong

Regards,

Ramzi
