Noctilucenthow to remove Cipher from SSL profile
Hi experts,
I wanted to remove below cipher form SSL profile.
10: 49200 ECDHE-RSA-AES256-GCM-SHA384 256 TLS1.2 Native AES-GCM SHA384 ECDHE_RSA 11: 49192 ECDHE-RSA-AES256-SHA384 256 TLS1.2 Native AES SHA384 ECDHE_RSA
Please help me to compose it.

Just 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

As 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.
