Configuring Diameter AVPs for Gx Applications

You can exclude Diameter attribute-value pairs (AVPs) from or include in the credit control request (CCR) messages between the MX Series router and the policy and charging rules function (PCRF) server.

Note:

The configuration of the Diameter AVPs for dynamic PCEF policies is optional.

To configure Diameter AVPs for Gx applications:

  1. Specify the name of the Diameter Gx profile for which you are configuring the Diameter AVPs.

    The Diameter Gx profile name can contain letters, numbers, and hyphens (-) and can be up to 128 characters long.

  2. Specify the optional AVPs to be excluded from the CCR messages between the MX Series router and the PCRF. By default, all AVPs are included in the CCR messages.

    You can specify more than one AVP in a single line.

    Table 1 describes the AVPs that you can exclude from CCR messages.
