Symptoms

MRF DIAMETER is not DIAMETER-application aware. It does not have application-specific business logic. When creating a DIAMETER solution, BIG-IP operators often need to write iRule scripts that remove a session persistence entry at the end of a transaction.

Impact

iRule script is required.

Conditions

Some applications require removal of the persistence entry upon successful completion of a transaction. Other applications require removal upon unsuccessful completion of a transaction.

Workaround

Systems requiring automatic removal of a session persistence entry must write iRule scripts that inspect the answer message for its success and then use the DIAMETER::persist reset iRule command.

Fix Information

It is not possible to instruct the system to automatically remove a persistence entry based on the result status of a answer message.
