A CEX Configuration Set provides a mechanism for assigning up to 10 unique Application Ids and up to 10 unique supported Vendor IDs to a Local Node or connection. A default CEX Configuration Set, called Default, is always available, and is pre-populated with the “RELAY” Application Id (0xFFFFFFFF).
Each Local Node will refer to a single CEX Configuration Set. The CEX Configuration Set is mandatory for Local Node. Each transport connection can optionally refer to a single CEX Configuration Set. During CEX message exchange, the CEX Configuration Set in the transport connection is used if configured. Otherwise, the CEX Configuration Set in the Local Node (associated with the transport connection) is used. A Vendor Id can be sent in the Supported-Vendor-ID AVP of a CEX even though the Vendor Id is not configured in the Selected Supported Vendor Ids for the CEX Configuration Set.
The application has a default CEX Configuration Set called Default, which is always available. The Default CEX Configuration Set options cannot be modified or deleted. When you create a new CEX Configuration Set the values of the Default CEX Configuration Set are automatically populated into the new CEX Configuration Set, allowing you to easily create a new CEX Configuration Set that needs to have only a few options adjusted.
Application Ids and Types (Authentication or Accounting) and Vendor Ids for Vendor Specific Application Ids can be configured on the CEX Parameters GUI pages. The configured CEX Parameters will appear for selection on the GUI pages for configuring CEX Configuration Sets.
