F5 client ssl cipher suites allowing anon auth

Need to understand how F5 handles ssl client profiles I have an issue raised that TLS_DH_anon_WITH_AES_128_CBC_SHA is allowed and needs to be blocked but in F5 config its not specifically allowed. These are allowed in there but my understanding is RSA is implied for auth in these cases and anon auth shouldnt work AES256-SHA:AES128-SHA:AES: Thanks
