Domain name for API request: clb.tencentcloudapi.com.
This API (ModifyListener) is used to modify the attributes of a CLB listener, such as listener name, health check parameter, certificate information, and forwarding policy.
This is an async API. After it is returned successfully, you can call the DescribeTaskStatus API with the returned RequestID as an input parameter to check whether this task is successful.
A maximum of 20 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
Parameter Name | Required | Type | Description |
---|---|---|---|
Action | Yes | String | Common Params. The value used for this API: ModifyListener. |
Version | Yes | String | Common Params. The value used for this API: 2018-03-17. |
Region | No | String | Common Params. This parameter is not required for this API. |
LoadBalancerId | Yes | String | CLB instance ID |
ListenerId | Yes | String | CLB listener ID |
ListenerName | No | String | New listener name |
SessionExpireTime | No | Integer | Session persistence time in seconds. Value range: 30-3,600. The default value is 0, indicating that session persistence is not enabled. This parameter is applicable only to TCP/UDP listeners. |
HealthCheck | No | HealthCheck | Health check parameter. It is only applicable only to TCP, UDP, TCP_SSL and QUIC listeners. |
Certificate | No | CertificateInput | Certificate information. This parameter is only applicable to HTTPS/TCP_SSL/QUIC listeners. Certificate and MultiCertInfo cannot be both specified. |
Scheduler | No | String | Listener forwarding method. Valid values: WRR, LEAST_CONN.These values respectively indicate weighted round robin and least connections. The default value is WRR.Use cases: This applies to TCP/UDP/TCP_SSL/QUIC listeners. The balancing method for Layer-7 listeners should be modified in the forwarding rules. |
SniSwitch | No | Integer | Whether to enable the SNI feature. This parameter applies only to HTTPS listeners. The default value is 0, indicating disabled, and 1 indicates enabled. Note: The SNI feature can be enabled for listeners that have not enabled SNI, but cannot be disabled for listeners that have enabled SNI. |
TargetType | No | String | Target backend type. NODE : A single node; TARGETGROUP : A target group. |
KeepaliveEnable | No | Integer | Whether to enable long connections. This parameter applies only to HTTP and HTTPS listeners.The default value is 0, indicating disabled, and 1 indicates enabled. |
DeregisterTargetRst | No | Boolean | Whether to send the TCP RST packet to the client when unbinding a real server. This parameter is applicable to TCP listeners only. |
SessionType | No | String | Session persistence type. NORMAL indicates the default session persistence type, and QUIC_CID indicates session persistence by QUIC connection ID. QUIC_CID only supports UDP protocols.Use cases: This applies to TCP/UDP/TCP_SSL/QUIC listeners. |
MultiCertInfo | No | MultiCertInfo | Certificate information. You can specify multiple server-side certificates with different algorithm types. This parameter is only applicable to HTTPS listeners with the SNI feature not enabled. Certificate and MultiCertInfo cannot be specified at the same time. |
MaxConn | No | Integer | Maximum number of concurrent connections at the listener level. This parameter is supported only for LCU-supported instances with TCP/UDP/TCP_SSL/QUIC listeners currently. Value range: 1 to the maximum number of concurrent connections for the instance specification. -1 indicates that no limit is set on the concurrent connections at the listener level. Classic network instances do not support this parameter. |
MaxCps | No | Integer | Maximum number of new connections at the listener level. This parameter is supported only for LCU-supported instances with TCP/UDP/TCP_SSL/QUIC listeners currently. Value range: 1 to the maximum number of new connections for the instance specification. -1 indicates that no limit is set on the new connections at the listener level. Classic network instances do not support this parameter. |
IdleConnectTimeout | No | Integer | Connection idle timeout period (in seconds). It’s only available to TCP listeners. Value range: 300-900 for shared and dedicated instances; 300-2000 for LCU-supported CLB instances. It defaults to 900. To set a period longer than 2000 seconds (up to 3600 seconds), please submit a submit. |
SnatEnable | No | Boolean | Whether to enable SNAT. |
Parameter Name | Type | Description |
---|---|---|
RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
