Don't think you can change that, as in the RADIUS Dictionary the NAS-Port is defined as an integer (number), and NAS-Port-Id is a string (free form text).
The solution for this would be to add the NAS-Port-Id to the Access Tracker view in ClearPass, however that would be a feature request (Innovation Zone). I could not see this requested before, but it feels like a useful feature for ClearPass to maybe even have arbitrary columns in Access Tracker. Innovation Zone is accessible through the Networking Support Portal.
