Enabling "Honor Cipher Order" on F5 LTM v12.X

not quite sure why those articles don't help, they explain it, pretty extensive in my opinion.

you don't create a DEFAULT or MYDEFAULT, the DEFAULT is a build in set. you are able to manipulate the selection by putting certain sets there like HIGH or RC4 or DCE. with the !RC4 for example you negate a selection.

but next to the sets you can also select the specific ciphers. just put the name in the Cipher field, for example "DHE-RSA-AES256-GCM-SHA384:AES128-SHA256"

do notice from here that not all ciphers you want are possible with F5, i.e. ECDHE-ECDSA-CHACHA20-POLY1305

that should set you off, if it doesn't work, show the error please
