You need to seperate the issues.
COA/Disconnect is an RFC standard.
acctupdate is not.

You can use either with chilli.

COA/Disconnect
--------------
You get a COA and a Disconnect.
Disconnect would ask the NAS (chillespot) to disconnect the client
COA can modify Authorisation parameters like time left or bandwidth available.

COA/Disconnect is sent from the radius server to the NAS (chilli)

acctupdate
----------
Chilli has implements a second (non RFC way) where the Accounting Reply can 
contain similar Radius Attibutes to what a COA packet would contain.

This is for cases where you cannot reach the NAS from the Radius server. 
(e.g. the NAS is behind a dynamic nat)

It works very well. (I use it here).


Cheers,
