The way the SSL Handshake works is that the client sends its supported ciphers and the server picks one of them, so to check what ciphers are supported by the server from a client point, you need to loop through an exhaustive list of ciphers one by one and try to connect to the server, this is why it needs to be scripted. I don't think F5 provides such script. If you can't use other options apart from F5 point, you can search for a bash, pythor or perl script to run from F5, but you will need to provide it with accurate list of ciphers. I would rather use other options as it's not the job of F5 to list server ciphers
