USER’S GUIDE

radius

Displays the current RADIUS server configuration data.

radacc

Allows you to change the current RADIUS Accounting Server configuration data. After entering the radacc command, you will be presented with a RADIUS Accounting Menu similar to that in CFGEDIT.

RADIUS ACCOUNTING SERVER CONFIGURATION ELEMENTS

RADIUS ACCOUNTING

You may enable or disable this feature. The default is disabled.

UDP PORT NUMBER

The UDP port number used by the RADIUS Accounting Server. This information is required for the Primary RADIUS Server, and also required if a Secondary RADIUS Server is configured. The officially-assigned port number for RADIUS Accounting is 1813.

Refer to the RADIUS Authentication Server Configuration Elements section for additional elements that are in common with the RADIUS Authentication Server.

RADIUS ACCOUNTING SERVER BACKGROUND INFORMATION

CyberSWITCH UAA software version 7.2 (or earlier) provides for a RADIUS implementation which uses RADIUS only for Authentication. CyberSWITCH UAA software version 7.3 (and beyond) provides the ability to use RADIUS to maintain accounting information as well. This additional capability should be especially useful to Internet Service Providers who have standardized on RADIUS for call accounting.

When enabled and properly configured, the CyberSWITCH software implements a RADIUS Accounting Client. The RADIUS Accounting Client sends accounting packets to the RADIUS Accounting Server. These packets support the following attributes:

•NAS-IP-Address

•NAS-Port-Type (in format abcdd, where a = WAN card slot, b=WAN port, c = modem card slot, and dd = modem number)

•Acct-Status-Type

•Acct-Session-Id

•User-Name

•Calling-Station-Id

•Framed-IP-Address

•Acct-Session-Time

When a call is initiated and authenticated successfully, CyberSWITCH software will send an accounting-request packet to flag a call “START”. When the call is terminated, it will send an accounting-request packet with a value of “STOP”. This packet exchange provides a means of determining the session time for the call (i.e., the number of seconds that the call has been active).

PERFORMANCE

RADIUS Accounting consumes an additional 32 bytes of memory per connection, or a total of 6144 bytes on a full, 192-connection system.
