NAS-Port-Type is an integer. Therefore, you need to use the Value
field, not the data field. If you look at the dictionary, you'll

VALUE NAS-Port-Type Async 0
VALUE NAS-Port-Type Sync 1
VALUE NAS-Port-Type ISDN-Async-V120 3
VALUE NAS-Port-Type ISDN-Async-V110 4
VALUE NAS-Port-Type Virtual 5

There, set data to blank or nULL and value = 0.
