Setting Parameters for Value-Added Services

Using parameters, you can define general settings in one object and provide specific values for that setting in another object. For example, you can define the general settings for a rate limiter in a policy, insert a parameter for a rate in the policy, and provide specific values for the rate in each service that uses this policy. For information about the concept of parameters, see Chapter 14, Defining and Acquiring Values for Parameters.

To configure parameters for value-added services:

  1. In the SDX Admin navigation pane, select a value-added service, and then click the Parameter tab.

The Parameter tab appears in the content pane.

  1. Use the field descriptions in Parameter Fields to configure parameters for value-added services.

Parameter Fields

Use the fields in this section to configure parameters for value-added services.

Gateway

Service IP

Service IP Mask

Service Port

Substitution

Session Volume Quota

If the Session Volume Quota attribute is defined in more than one place, which value is used depends on where the value is defined. The SRC software searches for the value in the following order:

  1. Value set in a call to the SAE
  2. Value set in an authorization
  3. Value set in a service definition

Configuring Substitutions

This section shows how to add, modify, validate, and delete substitutions in SDX Admin.

Adding Substitutions

To add a substitution:

  1. In SDX Admin, select the Parameter tab for the service to which you want to add a substitution.
  2. In the unlabeled field below the Substitution field, enter the substitution in the correct syntax (see Formatting Substitutions). For example:
  3. Click Add.

    NOTE: Substitutions for JUNOSe routers may not correctly display in the Substitution field for SDX Admin. To confirm the syntax of a JUNOSe substitution, click on the substitution in the Substitution field, and observe the syntax in the entry field below the Substitution field.


Substitutions to a Transmission Rate for a Scheduled Action

When you use SDX Admin to assign substitutions to the Transmit Rate Unit for a Scheduler action, you can specify one of the following:

Do not use the "rate_in_percent" value as it appears in Policy Editor for substitutions in SDX Admin. Do one or the other. For example in Policy Editor, specify a parameter called 'x' for the Transmit Rate Unit for a Scheduler Action and select rate_in_percent; or in SDX Admin, create a substitution as x = percent.

Modifying Substitutions

To modify a substitution:

  1. In SDX Admin, select the Parameter tab for the service to which you want to add a substitution.
  2. Select the substitution in the Substitutions field.
  3. Modify the substitution in the unlabeled field below the Substitution field.
  4. Click Modify.

Validating Substitutions

To validate a substitution:

  1. In SDX Admin, select Options > Configure.

The Main Configuration window appears.

  1. In the SAE Admin Web Application Server field, enter the identifier of the host on which you installed SAE Web Admin, in the format: <host>:<port>.
  1. Click OK.
  2. Select the substitution in the Substitution field.
  3. Click Validate.

SDX Admin displays the result of the validation.

Deleting Substitutions

To delete a substitution, select it in the Substitutions field, right-click, and select Delete.
