 * `certificate_ssl_mode` - (Optional, String, ForceNew) Type of certificate. Valid values: `UNIDIRECTIONAL`, `MUTUAL`. NOTES: Only supports listeners of HTTPS protocol.

 * `health_check_health_num` - (Optional, Int) Health threshold of health check, and the default is `3`. If a success result is returned for the health check 3 consecutive times, indicates that the forwarding is normal. The value range is [2-10]. NOTES: TCP/UDP/TCP_SSL listener allows direct configuration, HTTP/HTTPS listener needs to be configured in `tencentcloud_clb_listener_rule`.
 * `health_check_http_code` - (Optional, Int) HTTP Status Code. The default is 31. Valid value ranges: [1~31]. `1 means the return value '1xx' is health. `2` means the return value '2xx' is health. `4` means the return value '3xx' is health. `8` means the return value '4xx' is health. 16 means the return value '5xx' is health. If you want multiple return codes to indicate health, need to add the corresponding values. NOTES: The 'HTTP' health check of the 'TCP' listener only supports specifying one health check status code. NOTES: Only supports listeners of 'HTTP' and 'HTTPS' protocol.
 * `health_check_http_domain` - (Optional, String) Domain name of health check. NOTES: Only supports listeners of `HTTP` and `HTTPS` protocol.
