 * `certificate_ca_id` - (Optional, String) ID of the client certificate. NOTES: Only supports listeners of `HTTPS` and `TCP_SSL` protocol and must be set when the ssl mode is `MUTUAL`.
 * `certificate_id` - (Optional, String) ID of the server certificate. NOTES: Only supports listeners of `HTTPS` and `TCP_SSL` protocol and must be set when it is available.
 * `certificate_ssl_mode` - (Optional, String) Type of certificate. Valid values: `UNIDIRECTIONAL`, `MUTUAL`. NOTES: Only supports listeners of `HTTPS` and `TCP_SSL` protocol and must be set when it is available.
+* `deregister_target_rst` - (Optional, Bool) Whether to send the TCP RST packet to the client when unbinding a real server. This parameter is applicable to TCP listeners only.
 * `end_port` - (Optional, Int, ForceNew) This parameter is used to specify the end port and is required when creating a port range listener. Only one member can be passed in when inputting the `Ports` parameter, which is used to specify the start port. If you want to try the port range feature, please [submit a ticket](https://console.cloud.tencent.com/workorder/category).
 * `h2c_switch` - (Optional, Bool, ForceNew) Enable H2C switch for intranet HTTP listener.
 * `health_check_context_type` - (Optional, String) Health check protocol. When the value of `health_check_type` of the health check protocol is `CUSTOM`, this field is required, which represents the input format of the health check. Valid values: `HEX`, `TEXT`.
