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 15, Defining and Acquiring Values for Parameters.
To configure parameters for value-added services:
The Parameter tab appears in the content pane.
![]()
- 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
- Actual IP address of the gateway router. This value is substituted for the policy global parameter called gateway_ipAddress.
- Value—<IP address>
- Default—No value
Service IP
- Actual IP address of the host(s) that provides the service. This value is substituted for the policy global parameter called service_ipAddress.
- Value—<IP address>
- Guidelines—This entry is needed only if the policy group in the service is referencing this parameter.
- Default—No value
Service IP Mask
- Actual IP mask for the service. This value is substituted for the policy global parameter called service_ipMask.
- Value—<IP mask>
- Guidelines—This entry is needed only if the policy group in the service is referencing this parameter.
- Default—No value
Service Port
- Actual Transmission Control Protocol (TCP)/User Datagram Protocol (UDP) port for the service. This value is substituted for the policy global parameter called service_port.
- Value—<port number>
- Default—No value
Substitution
- Substitutions for other parameters (see Configuring Substitutions).
- Value—<substitution in correct syntax>
- Default—No value
Session Volume Quota
- Quota for the volume of data for service sessions. The SRC software uses this value as the default for service sessions created for this service.
- Value—<downstream Quota>.<upstreamQuota>
- <downstream Quota>—Number of bytes available for transmitting data from the network to the subscriber
- <upstreamQuota>—Number of bytes available for transmitting data from the subscriber to the network
- Guidelines—The value of a service session can be defined at runtime either through an authorization plug-in or a call to the SAE API.
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:
Configuring Substitutions
This section shows how to add, modify, validate, and delete substitutions in SDX Admin.
Adding Substitutions
- In SDX Admin, select the Parameter tab for the service to which you want to add a substitution.
- In the unlabeled field below the Substitution field, enter the substitution in the correct syntax (see Formatting Substitutions). For example:
![]()
- Click Add.
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
- In SDX Admin, select the Parameter tab for the service to which you want to add a substitution.
- Select the substitution in the Substitutions field.
- Modify the substitution in the unlabeled field below the Substitution field.
- Click Modify.
Validating Substitutions
The Main Configuration window appears.
![]()
- 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>.
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.
