Noctilucenthow to remove Cipher from SSL profile
Hi experts,
I wanted to remove below cipher form SSL profile.

NimbostratusJust use the exclamation mark to exclude a cipher suite you don't want, and append it to your cipher config. Assuming that you have no other cipher customization in place at this point, the end result would be
DEFAULT:!ECDHE-RSA-AES256-SHA384 tmm --clientciphers 'DEFAULT'

CumulonimbusAs Hannes has said.
Might also be worth investigating what current cipher string is in use under DEFAULT (It changes with each software version potentially)
Depending on your reasoning for stopping negotiation with that cipher, you may want to block the entire ECDHE Cipher suite.
