Setting extracted via rear port:

Answer for above:

Here customer need to set settingvalueBeh.(refer cell 09FE) as locked mode instead of independent.

Below is explanation:

Independent: cell [092E] Setting Values will be independent in each interface. For example, the Front Port can have [092E] set to Secondary and a remote port can have [092E] set to Primary.

Locked Mode: cell [092E] Setting Values are locked to the same value for all interfaces. All interfaces are have the same value for [092E]. Whichever interface selects Locked Mode will have its setting for [092E] applied to all interfaces. Any interface can then change [092E] and it will apply on all interfaces.
