How to change default cipher is 11.5.1

How to change default cipher in F5 with version 11.5.1 which does not allows sslv3 globally on protocol level to allow sslv3 for a particular vip.

 

Do i need to use compact ciphersuite for that particular VIP?If yes how will allow sslv3 in cipher for a particluar vip though this being not allowed globally on version 11.5.1 LTM

    You can enable SSLv3 on a particular VIP in the client-ssl profile for the VIP, by setting it to DEFAULT:SSLv3. If you want to do it globally modify the client-ssl profile named "clientssl."

    default 11.5.1 clientssl cipher is !SSLv2:!EXPORT:RSA+AES:RSA+3DES:RSA+RC4:ECDHE+AES:ECDHE+3DES:ECDHE+RC4:-MD5:-SSLv3

     

    in addition to default:sslv3, you may try !SSLv2:!EXPORT:RSA+AES:RSA+3DES:RSA+RC4:ECDHE+AES:ECDHE+3DES:ECDHE+RC4:-MD5
