3.3.5.2.2 MS-Quarantine-Session-Timeout
When a NAS that supports this attribute receives the attribute, it applies a time-out for the endpoint client connection set to the attribute's value, in seconds.
If the same endpoint client later gets an Access-Accept without this attribute (unrestricted), the time-out is dropped.
If the time-out expires while the connection is still in restricted quarantine, the NAS disconnects the endpoint connection. <17>
Clients that do not support this attribute ignore it.
For more details about this attribute, see section 2.2.1.4.
