Affected Product(s):
BIG-IP Install/Upgrade, LTM
Known Affected Versions:
11.4.0, 11.4.1
Fixed In:
11.5.0
Opened: Aug 14, 2013 Severity: 3-Major
If the default LTM Policy, '_sys_CEC_video_policy', was modified using the GUI, the changes were not persisted (saved to /config/bigip.conf) and will be lost if 'load sys config' is executed or during an upgrade. If modification was done with TMSH, the changes were persisted. It is a good practice to clone the default configurations and make modifications on the clone as well as assign the cloned configuration to the virtual server instead of the default configuration.
If rules were added, removed or updated or changes were made to the default policy itself using only the GUI they were not saved in /config/bigip.conf and may be lost during upgrade or when user executed 'load sys config'.
Modification of LTM Policy _sys_CEC_video_policy in the GUI.
TMSH can be used to force persistence. For example a TMSH command to 'modify ltm policy _sys_CEC_video_policy strategy first-match' (or any modification even if it does not change the configuration value) followed by 'save sys config' causes the setting to be saved in bigip.conf.
