About Parameter Templates
Parameter templates are a part of the action template. The parameter templates assigned to the action template serve as input parameters for the policy action at enforcement time. You can configure the required parameters of an action template in two ways:
Default values: You can define parameters with default values and select one of these values as the default value. When the action template and its associated parameter template are used in a policy, you can restrict the policy action to use only the defined default values.
Blank values: Alternatively, you can define parameters with blank values. When the action template and its associated parameter template are used in a policy, the policy action accepts any desired value.
