An interface is not filtered even though a monitoring profile is applied with a filter that should filter interface
CA Performance Management 3.5
From the documentation:
Important! CA Performance Management monitors device components if any of the monitored components pass the filter criteria of any associated monitoring profile.
So if a component would be allowed by any monitoring profile filter applied to the device, the component will pass
Make sure that no monitoring profile is applied to a collection the device is in has a filter that would not filter out the component
