====== Configuration of work with NOKIA attributes ======
===== Purpose =====
RADIUS defines requirements for the data composition in request and response packets, while allowing functionality to be extended for specific tasks using vendor specific attributes — attributes defined by a particular vendor, for example, to transmit data with non-standard semantics.\\
To ensure correct interaction, NOKIA BNG must correctly process attributes from SSG BNG and vice versa (SSG BNG acts as a RADIUS client, NOKIA BNG as a RADIUS server). For this purpose, FreeRADIUS provides a mechanism for dynamic processing of attributes passing through it in both directions.

===== Configuration of FreeRADIUS as a load-balancing VASE NAS proxy adapter for NOKIA AAA =====
The configuration archive is provided upon request by technical support engineers.

The archive contains the following directories:
  - ''scripts'' — scripts for emulating VASE NAS requests for debugging and verification. The scripts contain examples of authorization and accounting requests for test users.
  - ''proxy/raddb'' — FreeRADIUS configuration for adapting VASE NAS to NOKIA AAA.

<note tip>Adaptation of AUTH and ACCT requests is implemented; CoA support is planned to be added.</note>

To deploy in a production environment, it is required to:
  - install the FreeRADIUS server according to the [[https://freeradius.org/documentation/|installation guide]] on the software website.
  - replace the default configuration created by the installer with the configuration from the archive.
  - configure the source client addresses of VASE NAS and the target NOKIA AAA servers according to the instructions in [[dpi:dpi_components:freeradius:balancing_proxy]].
  - configure the source realms for VASE NAS users in the file ''proxy.conf'' (currently ''rlm_pppoe_prod_servers'' and ''rlm_ipoe_prod_servers'').
