NimbostratusHTTPS calls supporting TLS V 1.2
Hello,
I have a requirement that some of the applications with VIP's in F5 loadbalancer should support TLS 1.2. I thought of creating a SSL profile with cipher list as TLS V1_2. But i am not ver...
I don't think you need to do anything in particular to enable TLS1.2. It's one of the common features of the SSL/TLS handshake to pick the highest protocol version both parties support. Recent BigIP versions allow (and prefer) TLS1.2 to be used during client-side SSL handshake, unless you have disabled it yourself, or if your software version is badly outdated (10.2.2 and older). While TLS1.2 is given preference, there's nothing that by default would prevent your clients from falling back to older TLS versions if 1.2 is not supported.
- What is your BigIP verion? This SOL lists out the SSL/TLS versions which are enabled by the default clientssl profile configurations, or by the
Cipher String setting. https://support.f5.com/kb/en-us/solutions/public/13000/100/sol13156.htmlDEFAULT

NimbostratusThat helps. The handshake simulations, protocols are clearly saying that my BigIP supports all TLS versions for all types of clients. I think it will be good for my requirement. Thank you.
