Issue/Introduction
Sub Interfaces on our devices are showing high utilization where the physical port itself shows shows low to no traffic at all. Is this expected or could it relate to a counter issue?
Cause
Different speeds on the different interface items result in different X and Y labels/ratios making the charts look incorrect at first glance.
Environment
All supported Performance Management releases
Resolution
When comparing reports in this scenario it's important to be mindful of the Speed set on the target interface.
One set to 10 MB/s will have lower looking Utilization values than one with a 2.05 MB/s speed.
One set to 10 MB/s will have lower looking Utilization values than one with a 2.05 MB/s speed.
