There is a Campus Manager report which will show you ports with multiple MAC addresses. Go to Campus Manager > User Tracking > Reports > Report Generator > Duplicates. This will show you all ports which have at least two learned MAC addresses.
For every port which has more than one learned MAC, the details for each MAC is listed in the report. For example, if switchA port Fa0/1 has three MACs, you will see three entries each having device name switchA and port Fa0/1.
This is not a best practice deviation, but a different report altogether.
Is there anyway to customize this report, or build a custom report so that it does the same thing with subtle changes. The reason I ask is because the report generated for me lists all the mac address per port, even if it is just a single mac. Is it possibly a bug?
