F5 LTM Default Ciphers

Hi all, I have a tcpdump where the client is unable to reach the VIP on port 443 which i can see it's using TLS1.2

I was just checking on my newly setup F5 LTM 12.0.0 and notice the below after running "tmm --clientciphers DEFAULT" Does this means no ciphers is enabled by default ? how do i enabled it ?

[adm@Host:Active:Changes Pending] ~  tmm --clientciphers DEAFULT
       ID  SUITE                            BITS PROT    METHOD  CIPHER    MAC     KEYX
[adm@Host:Active:Changes Pending] ~

    Hi Doran. The DEFAULT cipher list actually includes a very robust set of ciphers. Here's a link to show you the list of ciphers included in the DEFAULT list.

    You are unable to see the ciphers because of a typo in the command ( "tmm --clientciphers DEAFULT" )

     

    The DEFAULT is mentioned as DEAFULT. :)

    there is a spelling mistake of "DEFAULT" is type incorrectly, type right spelling and it will come: ==========================Correct Spelling of DEFAULT================================= [adm@Host:Active:Changes Pending] ~ tmm --clientciphers DEFAULT
