How to enable Acct-Interim-Interval?

I'm not quite sure how to enable Acct-Interim-Interval in free radius.


post-auth {
        update reply {
                Acct-Interim-Interval = 60

I still can't see the accounting data (Octlets) to be updated after 60
Only after I disconnect the connection, I can see them updated.

Before my NAS is accused of not supporting it, I can see it does:

Interval in seconds for interim RADIUS accounting updates, if not specified
> by the RADIUS server in the Access-Accept message.

What am I missing, please?
