Custom cihper suite for ClientSSL Profile
Hello Folks,
I want to use a custom set of ciphers in my ClientSSL Profile. I have gone through the document of F5, how can disallow ciphers by putting
!
However I have a requirement that I need to use only 2 cipher suites such as
AES128-SHA256 & AES256-SHA256 and rest should be deny. How can I deny remaining cipher suites by allowing only the required one?
Any help is appreciated.
Cheers! Darshan

e.g.
[root@ve11a:Active:In Sync] tmp tmm --clientcipher aes128-sha256:aes256-sha256:@strength ID SUITE BITS PROT METHOD CIPHER MAC KEYX 0: 61 AES256-SHA256 256 TLS1.2 Native AES SHA256 RSA 1: 60 AES128-SHA256 128 TLS1.2 Native AES SHA256 RSA - Vitaliy_Savrans

or from GUI
Local Traffic ›› Profiles >> SSL >> Client >> Profile_Name (advance mode)>> Ciphers aes256-sha256:aes128-sha256system will promt ciphers in order to input string at first aes256 then aes128

nice tool to test ssl configuration https://www.ssllabs.com/ssltest/ - swo0sh_gt_13163

Would this disable other ciphers suites from being used?

Also, will it be any downfall?

If implemented, LTM will only Do SSL handshake with these ciphers,

Thank you all! It worked exactly as expected.
For internal test, I have used wireshark and verified the server side cipher suite.
For external test, as suggested above, sslabs is always helpful.
Thank you again,
