disabling protocol

Hi, What is the difference between the below procedures 1) tmsh modify sys http ssl-protocol 'all -SSLv2 -SSLv3 -TLSv1'

tmsh list sys http ssl-protocol sys httpd { ssl-protocol "all -SSLv2 -SSLv3 -TLSv1" }

2) tmsh list /ltm profile client-ssl Test options ltm profile client-ssl Test { options { dont-insert-empty-fragments no-tlsv1 } }

If we want to disable tlsv1 and keep only tlsv1.1 and 1.2 , it can be do with CIPHERS ? ( ciphers DEFAULT) ,If yes what would be the string ?

Thanks
