：CreateListener

The operation that you want to perform. Set the value to CreateListener.

The listener protocol. Valid values: TCP, UDP, and TCPSSL.

The listener port. Valid values: 0 to 65535.

If you set the value to 0, the listener listens by port range. If you set the value to 0, you must specify StartPort and EndPort.

The name of the listener.

The name must be 2 to 256 characters in length, and can contain letters, digits, commas (,), periods (.), semicolons (;), forward slashes (/), at signs (@), underscores (_), and hyphens (-).

The NLB instance ID.

The server group ID.

The timeout period of idle connections. Unit: seconds.

Valid values: 1 to 900. Default value: 900.

The security policy ID. System security policies and custom security policies are supported.

• Valid values for system security policies: tls_cipher_policy_1_0 (default), tls_cipher_policy_1_1, tls_cipher_policy_1_2, tls_cipher_policy_1_2_strict, and tls_cipher_policy_1_2_strict_with_1_3.
• Custom security policy: the ID of the custom security policy.
  • For more information about how to create a custom security policy, see CreateSecurityPolicy.
  • For more information about how to query security policies, see ListSecurityPolicy.

The server certificates. This parameter takes effect only for listeners that use SSL over TCP.

The certificate authority (CA) certificates. This parameter takes effect only for listeners that use SSL over TCP.

Specifies whether to enable mutual authentication. Valid values:

• true
• false (default)

Specifies whether to perform only a dry run, without performing the actual request. Valid values:

• true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned.
• false (default): performs a dry run and performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.

The client token that is used to ensure the idempotence of the request.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters.

The region ID of the NLB instance.

You can call the DescribeRegions operation to query the most recent region list.

Specifies whether to use Proxy Protocol to pass client IP addresses to backend servers. Valid values:

• true
• false (default)

Specifies whether to enable fine-grained monitoring. Valid values:

• true
• false (default)

Specifies whether to enable Application-Layer Protocol Negotiation (ALPN). Valid values:

• true
• false (default)

The ALPN policy. Valid values:

• HTTP1Only: uses only HTTP 1.x. The priority of HTTP 1.1 is higher than the priority of HTTP 1.0.
• HTTP2Only: uses only HTTP 2.0.
• HTTP2Optional: preferentially uses HTTP 1.x over HTTP 2.0. The priority of HTTP 1.1 is higher than the priority of HTTP 1.0, and the priority of HTTP 1.0 is higher than the priority of HTTP 2.0.
• HTTP2Preferred: preferentially uses HTTP 2.0 over HTTP 1.x. The priority of HTTP 2.0 is higher than the priority of HTTP 1.1, and the priority of HTTP 1.1 is higher than the priority of HTTP 1.0.

The first port in the listener port range. Valid values: 0 to 65535.

The last port in the listener port range. Valid values: 0 to 65535.

The number of the last port must be greater than the number of the first port.

The maximum number of connections that can be created per second on the NLB instance. Valid values: 0 to 1000000. 0 specifies that the number of connections per second is unlimited.

The maximum size of a TCP segment. Unit: bytes. Valid values: 0 to 1500.

0 specifies that the maximum segment size remains unchanged.

The request ID.

The listener ID.

The ID of the asynchronous task.
