The inherit-certkeychain attribute of a child Client SSL profile can unexpectedly change after upgrade.


An incorrect cert key chain is used in the profile.


This issue occurs when all of the following conditions are met: -- You create a Client SSL profile that does not inherit the certificate, key, and chain certificate settings from the parent profile. -- You upgrade to BIG-IP 11.5.1 (HF6 or later), 11.5.2, 11.5.3, or 11.6.0.


Manually edit bigip.conf to contain the correct value. To do so, add the following line into child client ssl profile: inherit-certkeychain false Run the command: tmsh load sys config

Fix Information

The certificate, key, and chain certificate settings in a Client SSL profile no longer change after an upgrade.
