Are you using wired networks (i.e., IEEE 802.1X for Ethernet)? If yes,
please note that hostapd does not include port access entity (PAE). In
other words, it does not enforce the port authorized/unauthorized
processing or in any way change how data frames are passed through.
If you want to block the frames on an unauthorized port in a wired
network, you will need to use external mechanism (e.g., a kernel module
to implement PAE functionality or Linux bridge filtering/ibtables) to do
this and modify hostapd wired driver wrapper (driver_wired.c) to
configure the external mechanism to block/unblock the port based on IEEE
802.1X authorization state.
