Netflow reports twice as much bandwidth

Netflow reports twice as much bandwidth

I recently posted an issue where we were seeing incorrect results and we found it was due to the IP group bandwidth was being reported across multiple ports on the switch as we uplink to an external network.

howerver I am also seeing an issue with the physical ports as well. If I look at the usage in Netflow on the device port which uplinks to our ISP it reports twice as much bandwidth being used as what our ISP are telling us we are using.

I have double checked we are not getting confused with Gb and GB

we are using procurve 2824 Gb switches

Any ideas why the usage would be so differenent?
