You can put accounting into both the radacct & database if you want.
What is the use of Acct-Interim-Interval? Is it not possible to get the
update using this? Is it the received from radius server as a
Authentication/Accounting response? or NAS has to send it as a request?
Acct-Interim-Interval is a value, sent from the radius server to the
NAS, in the authentication response.
It instructs the NAS to send interim accounting packets to the radius
server, at the interval given. For example:
NAS: access-reqest
Srv: access-accept Acct-Interim-Interval = 300 (5 minutes)
NAS: Accounting-Start
<300 second gap>
NAS: Accoounting-Alive inbytes=10000 outbytes=10000
<300 seconds gap>
NAS: Accoounting-Alive inbytes=20000 outbytes=20000
...
NAS: Accounting-Stop
If the radius server doesn't give Acct-Interim-Interval, the NAS may
have a default value, or may not send interim accounting at all.
To repeat the answer to your original question: there is no mechanism in
radius (or extension in FreeRadius) for a NAS to query a radius server
for accounting.
Accounting is one-way - NAS -> Radius server.
You will need to use another method (query the files, or query a
database) to do what you asked.
