    Server Load Balancer:UpdateLoadBalancerAttribute

    Last Updated:Aug 01, 2024

    Modifies the attributes of an Application Load Balancer (ALB) instance, such as the name and the configuration read-only mode.

    Operation description

    UpdateLoadBalancerAttribute is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call GetLoadBalancerAttribute to query the status of the task.

    • If the ALB instance is in the Configuring state, the ALB instance is being modified.
    • If the ALB instance is in the Active state, the ALB instance is modified.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    ClientTokenstringNo

    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.

    Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.
    		5A2CFF0E-5718-45B5-9D4D-70B3FF3898
    DryRunbooleanNo

    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: performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed. This is the default value.
    		true
    LoadBalancerIdstringYes

    The ID of the ALB instance.

    		alb-o9ulmq5hgn68jk****
    LoadBalancerNamestringNo

    The name of the ALB instance. The name must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). The name must start with a letter.

    		lb-instance-test
    ModificationProtectionConfigobjectNo

    The configuration read-only mode.

    ReasonstringNo

    It must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). It must start with a letter.

    This parameter takes effect only when ModificationProtectionStatus is set to ConsoleProtection.

    		test
    StatusstringNo

    The status of the configuration read-only mode. Valid values:

    • NonProtection: disables the configuration read-only mode. In this case, you cannot specify ModificationProtectionReason. If you specify ModificationProtectionReason, the value of the parameter is cleared.
    • ConsoleProtection: enables the configuration read-only mode. In this case, you can specify ModificationProtectionReason.
    Note If you set this parameter to ConsoleProtection, you cannot use the ALB console to modify instance configurations. However, you can call API operations to modify instance configurations.
