  1. Have you applied the iRule to the VIP in question?

  2. Do you have a Client SSL profile applied to the VIP in question? If your back-end server ssl based then you have to apply server side ssl profile too for both side ssl offload.

     

    If there is no SSL profile applied, big-ip will not do ssl offload and you will not be able to identify negotiated cipher suit
