PPPoE "authentication interval"

Is there a way for an active pppoe connection to be checked for authorization at a specified time interval?

Example,

I connect with my pppoe client, 10 minutes later my account is disabled. I am still connected since I was previously authenticated.

I would like to implement a “re-authentication” interval to check every x minutes to make sure I am still authorized to access the network.

Is this possible?

Thanks,

Can you pont me in a more specific direction? Do I need to look at the “Disconnect-Messages” portion?

Does this feature require additional configuration of my radius server?

Thanks,

it is link on ‘Connection Terminating from RADIUS’ section

look at ‘dialup.radkill’ (FreeRADIUS?) script
