  • Hello friend , 
            you are prompted to this shap while opening your F5 Big-IP appliance first time. 
    you need to use the default credentials first as below : 
    > localhost login : root 
    > Password : default

    >(current) UNIX password: default 
    " enter the default Password again for UNIX " 

    After That you are prompted to set the new root Password and Confirmation as well. 

    Then , F5 Command line Bash prompt will appear for you.

    I hope my reply meets your needs. 🙂
