ModifyListener - Elastic Load Balancing

ModifyListener

Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.

Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.

To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

AlpnPolicy.member.N

[TLS listeners] The name of the Application-Layer Protocol Negotiation (ALPN) policy. You can specify one policy name. The following are the possible values:

  • HTTP1Only

  • HTTP2Only

  • HTTP2Optional

  • HTTP2Preferred

  • None

For more information, see ALPN policies in the Network Load Balancers Guide.

Type: Array of strings

Required: No

Certificates.member.N

[HTTPS and TLS listeners] The default certificate for the listener. You must provide exactly one certificate. Set CertificateArn to the certificate ARN but do not set IsDefault.

To create a certificate list, use AddListenerCertificates .

Type: Array of Certificate objects

Required: No

DefaultActions.member.N

The actions for the default rule.

Type: Array of Action objects

Required: No

ListenerArn

The Amazon Resource Name (ARN) of the listener.

Type: String

Required: Yes

Port

The port for connections from clients to the load balancer. You cannot specify a port for a Gateway Load Balancer.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 65535.

Required: No

Protocol

The protocol for connections from clients to the load balancer. Application Load Balancers support the HTTP and HTTPS protocols. Network Load Balancers support the TCP, TLS, UDP, and TCP_UDP protocols. You can’t change the protocol to UDP or TCP_UDP if dual-stack mode is enabled. You cannot specify a protocol for a Gateway Load Balancer.

Type: String

Valid Values: HTTP | HTTPS | TCP | TLS | UDP | TCP_UDP | GENEVE

Required: No

SslPolicy

[HTTPS and TLS listeners] The security policy that defines which protocols and ciphers are supported.

For more information, see Security policies in the Application Load Balancers Guide or Security policies in the Network Load Balancers Guide.

Type: String

Required: No

Response Elements

The following element is returned by the service.

Listeners.member.N

Information about the modified listener.

Type: Array of Listener objects
