User-Defined Variables
In service profiles, the Junos OS enables you to configure custom variables at the [dynamic-profiles profile-name variables] hierarchy level and associate those variables with supported RADIUS VSAs. The dynamic profile obtains and replaces data for these variables from an external server (for example, from RADIUS authentication and authorization VSAs) during the subscriber authentication process. At run time, the variables are replaced by these actual values (obtained from default information on the router or from the RADIUS server) and are used to configure the subscriber interface.
For a complete list of supported RADIUS VSAs for which you can create variable associations, see RADIUS Attributes and Juniper Networks VSAs Supported by the AAA Service Framework.
You can also configure the user-defined variables with a default value. The default value provides a standalone configuration for the associated statement or a backup for the statement configuration if the RADIUS server is inaccessible or the VSA attribute does not contain a value.
