XI.2.3 - Radius requests

To authenticate a user, the NAS emits a request ("Access Request") toward the Radius
server. The Radius server can reject the request ("Access Reject") or accept the request
("Access Accept").
If the request is accepted, the NAS can inform the Radius server about the starting and
ending of the
session ("Accounting Request").
Radius requests carry several attributes. The following table shows the requests emitted
by the NAS.
