prepaid volume quota with cisco nas

[Anirudh Malhotra]

Hi,

Check this out if it helps. You want to renew data quota every hour to 5 MB, and whenever the data limit is reached you want to deny the access for that hour. Right?

So two cases are made out of this:

To deauth user whenever limit is reached****
- Check accounting packets on every packet run a query on radacct to check if limit is reached for this hour, if it has, send a disconnect. This will enter a "admin-reset" in accounting stop packet in radacct table.

To stop user from authenticating when limit is reached****
- Run a query on sql radacct to check whether the user has been "admin-reset"(this would be sent from case 1 where limit is reached) for this hour, if it has, reject the request.


BR,
Anirudh Malhotra
