User’s Guide Version 1.0
To edit RADIUS server click the edit button:
Figure 112 – Add New RADIUS Server
Name – specify the new RADIUS server name.
Default – check the check box to make the selected RADIUS the default server.
Authentication IP – authentication RADIUS server IP address [dots and digits].
Authentication Port – specify the network port used to communicate with RADIUS [1-65535].
The port default value of 1812 is based on RFC 2138 "Remote Authentication Dial-
in User Service (RADIUS)".
Authentication Secret – shared secret string that is used to encrypt data frames used for
authentication server.
Accounting IP – accounting RADIUS server IP address [dots and digits].
Accounting Port – specify the network port used to communicate with RADIUS [1-65535].
Accounting Secret – shared secret string that is used to encrypt data frames used for accounting
server.
Backup IP – backup RADIUS server IP address [dots and digits].
Backup Port – specify the network port used to communicate with RADIUS [1-65535].
Backup Secret – shared secret string that is used to encrypt data frames used for backup server.
Shared secret must be the same on RADIUS server and RADIUS client.
Reverse Accounting – [enabled/disabled]. The RADIUS accounting request contains Acc-Input-
Octets and Acc-Output-Octets attributes. The interpretation of these attributes according the
RFC2866 is relative to the point of view. If this point is at the AC - Acct-Input* attributes should contain
the bytes/packets received at AC port from the client and Acct-Output* attributes should contain
bytes/packets sent from AC port to the client. If we move this point to the client - we will get the
reversing of Acct-Input* and Acct-Output* attributes values. The Acct-Input* then should contain
bytes/packets received from AC, what is bytes/packets that AC sent to the user in AC point of view
and what was Acct-Output*.
The AC implementation of RADIUS accounting request is at the client point of view
(reverse accounting is disabled).
