Which version of ClearPass supports TLS version 1.2 for TLS-based EAP methods?
Is it possible to disable TLS 1.2, if any of my client device is not able to authenticate using TLS 1.2?
TLS version 1.2 support is available from ClearPass 6.5.2 for TLS-based EAP methods.
A new RADIUS service parameter "Disable TLS 1.2" is available from ClearPass 6.5.2 to disable TLS version 1.2.
To disable TLS 1.2, navigate to Administration >> Server Manager >> Server Configuration >> click on Server Name and go to Service Parameters >> Radius Server >> Main >> and set the knob Disable TLS 1.2 to TRUE.
Note: Service Parameters is not a global configuration. So any changes to the service parameters should be performed on all the nodes in the Cluster.
