whether default cipers supports to TLS 1.0 in TMOS 13.1.1 or not.

Hi,

You have all info needed in this article (K13163: SSL ciphers supported on BIG-IP platforms (11.x - 13.x)):

https://support.f5.com/csp/article/K13163

As you can noticed, TLS1.2 is supported in the NATIVE SSL stack in BIG-IP 13.0.0 - 13.1.0.

You don't need to enable it by default. but you can force it (use only tls1.2). but in this case client that not support tls1.2 will receive a reset.

regards,
