SummaryWhen you add up the appliance bandwidth of each device in the aggregate interface report they do not sum up to aggregate bandwidth.
OverviewWhy does the aggregate interface report throughput an addition/sum of the per appliance throughout of the devices in the aggregate report?
The aggregate interface throughput graph shows:
1. The maximum bandwidth, this is usually shaded blue. If only one device has the highest bandwidth throughout the period that is selected then that device's maximum throughout will be the one on the maximum throughout.
2. The average throughput is an average, as such will give an average of all the appliances.
The aggregate interface throughput graph is displaying properly, and does not display the stacked throughput.
