Environment

Component : IM Reporting / Admin / Configuration

Resolution

There are circumstances where this is possible.

There may be data on some device/s that is calculating at over 100% due to the wrong ifSpeed being reported by the device. To check if this is the case, run a max report for last 30 days for the same group and see if you can find the interface/s.

Then check the ifSpeed for them.
