Opened: May 13, 2021
Severity: 4-Minor

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 and unsuccessful completion of a transaction. root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos)# list ltm rule log_dia_error ltm rule log_dia_error { when DIAMETER_INGRESS { set cmd_code [DIAMETER::command] if { $cmd_code == 272 } { set cc_req_type [DIAMETER::avp data get 416 integer32] if {[DIAMETER::is_response] && $cc_req_type == 3 } { log local0. "Persistence record delete-on-any" DIAMETER::persist delete-on-any } } }

Workaround

None

Fix Information
