NimbostratusAdding a new crypto set to the SSL Client Profile
I would like to add the support for the following ciphers to a specific SSL Client Profile on the LTM. I believe that I need to enter it into Configuration\Advanced\Ciphers in the new client profile. (I do not want to modify the default cipher list.)
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 TLS_RSA_WITH_AES_128_CBC_SHA256 TLS_DHE_DSS_WITH_AES_128_CBC_SHA256 TLS_DHE_RSA_WITH_AES_128_CBC_SHA TLS_RSA_WITH_AES_128_CBC_SHA TLS_DHE_DSS_WITH_AES_128_CBC_SHA
For example, for the fist one on the list, should the strings I put in look like the following? DEFAULT:ECDHE:ECDSA:AES128:CBC:SHA256 In case this is added, would all the cipher sets be still available in this SSL Client Profile? In case that I would only like to use the specific cipher set for this Client Profile, would I just use something like: ECDHE:ECDSA:AES128:CBC:SHA256
Thank you

you may check cipher suite yourself using tmm --clientciphers command.
sol15194: Overview of the BIG-IP SSL/TLS cipher suite
https://support.f5.com/kb/en-us/solutions/public/15000/100/sol15194.html 
kva_178637This would only allow me to search the ciphers currently set up. For example using tmm --clientciphers HIGH will give me a list of the more secure ones that are already available.
I am looking at adding clientciphers that are not defined yet, using something along the lines of the following KO: https://support.f5.com/kb/en-us/solutions/public/13000/100/sol13171.html
My question is, can I add a clientcipher that isn't listed using the following: ECDHE:ECDSA:AES128:CBC:SHA256 (and what would be the difference if one used DEFAULT:ECDHE:ECDSA:AES128:CBC:SHA256, forgive if the answer is obvious.)
Thank you for your help

Hi Nitass, thank you very much for your answer. This helped me to resolve my issue!!!
When I try this command on our 11.4.1 system, I don't see any ECDHE with SHA256:

One of the combinations that would make the system work is: TLS_DHE_RSA_WITH_AES_128_CBC_SHA The following looked like they could work (since I read someplace that the CBC is optional normally), so I tested using DHE.
