As per RFC 2865 and RFC 2866, port 1812 is used for Authentication and port 1813 is used for Accounting. If a port number other than 1812 or 1813 is needed the port number being used can be modified through the object in the ClientView application
If implementing both Authentication and Accounting, the Authentication process can be run on one RADIUS Server and the Accounting process can be run on a separate RADIUS Server -or- both Authentication and Accounting processes can be run on one RADIUS Server. Verify the RADIUS Servers are all configured correctly. Refer to the object for more information on setting up Authentication and Accounting on one or more RADIUS Servers.
The RADIUS attributes and VSA’s included in the RADIUS messages will vary based on the following:
The Protocol utilized.
What leg of the call the protocol is used on.
Whether the protocol is TDM (SS7 or ISDN) or IP (SIP).
The User name and Password values configured for the Authentication Server used will be included in the user name and password attributes in the Access-Request message sent from the IMG.
See IMG 1010 - Configure RADIUS topic for more information on how to configure RADIUS on the IMG.
