RADIUS Client Settings
RADIUS
(Remote Authentication Dial In User Service) specifies the RADIUS protocol used for authentication, authorization and accounting, to
differentiate, to secure and to account for the users. The RADIUS Server provides the option for a caller from/through QX to pass authentication and to be
able to dial a specific number.
When a RADIUS client is enabled on the QX, and according to the configuration of
AAA Required
), the RADIUS server will
be used to authenticate user and/or to account for the call. This can be accomplished by automatic detection of the caller’s number or a customized login
prompt where the caller is expected to enter a username and password.
Transactions between the client and the RADIUS server are authenticated through the use of a shared Secret Key, which is never sent over the network. In
addition, user passwords are encrypted when sent between the client and RADIUS server to eliminate the possibility of a party viewing an unsecured
network where they could determine a user's password. If no response from the RADIUS Server is returned after the Receive Timeout expires, the request
is resent numerous times as defined in the Retry Count list. The client can also forward requests to an alternate server(s) if the primary server is down or
unreachable. An alternate server can be used after a number of failed tries to the primary server.
Once the RADIUS server receives the request, it determines if the sending client is valid. A request from a client that the RADIUS server does not recognize
must be silently discarded. If the client is valid, the RADIUS server consults a database of users to find the user whose name matches the request. The user
entry in the database contains a list of requirements (username, password, etc.) that must be met to give access to the user. If all conditions are met, the
user gets access to the QX Network.
