Hi Avin, Please how did you resolve this case cos I am having exactly the same issue only that I have ISE 2.6. I already configured the rules and policies, installed the anyconnect on the workstation but ISE keeps showing:
Please double check your posture policy matching conditions or share a screenshot of your posture policy. Bypassing scan typically means that you are not hitting (matching) a posture policy. @Rizwan123 check specifically under: Policy->Posture->posture policy you want it to match->Operating Systems: to see what you have configured. I am guessing that you dont have 11.5 configured for support. HTH!
