RADIUS NAS-IP Support

SMF supports the RADIUS NAS-IP address functionality for accounting and authentication requests.

In releases prior to 2021.1.0, only one common RADIUS NAS-IP address was used for all requests. This feature is extended to support multiple RADIUS NAS-IP source addresses.

The NAS-IP configuration is supported at the following levels:

  • Global NAS-IP

  • Global accounting NAS-IP

  • Per server-group common NAS-IP

  • Per server-group accounting NAS-IP

The selected NAS-IP is encoded in authentication or accounting requests as per RFC2865 and is also used in the "source-ip" address of outbound UDP packets. This feature supports only the IPv4 NAS-IP address.

For more information, see the Configuring RADIUS NAS-IP section.
