Block CBC

Hi there,

I'm having a challenge on Blocking entirely the CBC cipher.

The ciphers I'm using are:

ECDHE-RSA-AES128-GCM-SHA256
ECDHE-RSA-AES128-SHA256
ECDHE-RSA-AES256-GCM-SHA384
ECDHE-RSA-AES256-SHA384
ECDHE-ECDSA-AES128-GCM-SHA256
ECDHE-ECDSA-AES256-GCM-SHA384
ECDHE-ECDSA-AES256-SHA384
ECDHE-ECDSA-CHACHA20-POLY1305-SHA256
ECDHE-RSA-CHACHA20-POLY1305-SHA256
ECDHE-ECDSA-AES128-SHA256

The problem is that even the above ciphers are selected, the testing shows that the F5 can communicate with CBC.

Any further configuration needed here 

Thank you

A
