Known Affected Versions:

Fixed In:
12.0.0 HF3
Opened: Sep 09, 2015 Severity: 3-Major
Changing the LSN pool mode may result in a TMM core if the BIG-IP is processing translations and the resulting config is not supported. When the pool mode changes while a translation is in progress validation checks may be skipped. This can cause a NULL pointer exception.
Traffic disrupted while tmm restarts.
Vlans configured with default DAG. A small LSN pool configured with NAPT mode. Changing the pool mode to PBA while translations are in progress. PBA is not supported with default DAG.
None
With this fix, tmm no longer crashes when changing the LSN pool to an unsupported mode.
