Additional Expression | The Additional Expression is optional. Enter an APL code expression that is going to be evaluated along with the ID Fields. Use the The Additional Expression is useful when you have several UDR types with a varying number of ID Fields, that are about to be consolidated. Having several UDR types requires the ID fields to be equal in number and type. If one of the types requires additional fields that do not have any counterpart in the other type or types, these must be evaluated in the Additional Expression field. Save the field contents as a session variable, and compare the new UDRs with it. For an example, see Association - Radius UDRs in Aggregation Example - Association of IP Data.

Create Session on Failure | Select this check box to create a new session if no matching session is found. If the check box is not selected, a new session will not be created when no matching session is found.
If the order of the input UDRs is not important, all the rules should have this check box checked. This means that the session object is going to be created regardless of the order in which the UDRs arrive. However, if the UDRs are expected to arrive in a particular sequence, Create Session on Failure must only be selected for the UDR type or field that is considered to be the master UDR, i e the UDR that marks the beginning of the sequence. In this case, all the slave UDR types or fields are targeted for error handling if they arrive before their master UDR.

Add Rule | Click this button to add a new rule for the selected UDR Type. The rule will appear as a new folder to the right of the UDR Types in the Aggregation profile configuration. Usually only one rule is required. However, in a situation where a session is based on IP number, stored in either a target or source IP field, two rules are required. The source IP field can be listed in the ID Fields of the first rule and the target IP field listed in the ID Fields of the second rule. | ||||||||||
