Hi,
Just trying to understand why there is a consistent ~50% discrepancy between the input data rate of the SPAN source interface and the output data rate of the SPAN destination interface?
Input/output rates seem to align for another monitor session running on the same switch.
Any insight would be greatly appreciated! Thanks.
