This depends on your NAS (i.e. access point).

If the NAS support packet-of-disconnect or CoA,  you can send them a 
radius request, directed to the NAS, to disconnect the session. The 
command line tool "radclient" can be used to send these. Consult the 
docs for your NAS to find out what attributes you will need to send - 
commonly you'll need username and accouting session ID.

If the NAS doesn't support PoD/CoA, you will need to again consult the 
NAS docs for other methods, such as using SNMP or expect/telnet to 
remove a session.
