Properties

Property Type Required Editable Description Constraint
ResourceGroupId String No No The ID of the resource group to which the SLB instance belongs. None.
VSwitchId String No No The ID of the vSwitch. The vSwitch must be in the same VPC as the source SLB instance. If you do not specify this parameter, the vSwitch of the source SLB instance is used.
SourceLoadBalancerId String Yes No The ID of the SLB instance to be cloned. None.
BackendServersPolicy String No No The clone policy, which specifies the ECS instances listened by the new SLB instance and the weight of each ECS instance. Default value: clone. Valid values:
  • clone: The ECS instances listened by the source SLB instance and the weight of each ECS instance are cloned to the new SLB instance.
  • empty: No ECS instances are attached to the new SLB instance.
  • append: The ECS instances listened by the source SLB instance and the weight of each ECS instance are cloned to the new SLB instance. New ECS instances that have weights specified are also attached to the new SLB instance.
  • replace: New ECS instances that have weights specified are attached to the new SLB instance. However, the ECS instances listened by the source SLB instance and the weight of each ECS instance are not cloned to the new SLB instance.
BackendServers List No Yes The list of new ECS instances to be listened. For more information, see BackendServers properties.
LoadBalancerName String No No The name of the new SLB instance. You can customize the instance name. The name must be 1 to 80 characters in length, and can contain letters, digits, hyphens (-), forward slashes (/), periods (.), and underscores (_).
Tags List No Yes The list of tags to be bound to the SLB instance. Tags must be specified as key-value pairs. A maximum of five tags can be specified.

For more information, see Tags properties.

TagsPolicy String No No The policy for handling tags. Default value: empty. Valid values:
  • clone: The tags of the source SLB instance are used.
  • empty: No tags are configured.
  • append: The tags of the source SLB instance are reserved while new tags are added.
  • replace: The tags of the source SLB instance are deleted while new tags are added.

BackendServers properties

Property Type Required Editable Description Constraint
ServerId String Yes Yes The ID of the backend server. Only ECS instances in the running state can be attached to the SLB instance as backend servers. A maximum of 20 backend servers can be attached each time.

You can specify elastic network interfaces (ENIs) as the backend servers for only guaranteed-performance SLB instances.

Weight Integer Yes Yes The weight of the ECS instance to be attached to the SLB instance. Valid values: 0 to 100.

Default value: 100.
ServerIp String No No The IP address of the backend server. None.
Type String No No The type of the backend server. Default value: ecs. Valid values:
  • ecs: ECS instance
  • eni: ENI
  • eci: Elastic Container Instance (ECI)
Description String No Yes The description of the backend server. The description must be 1 to 80 characters in length and can contain letters, digits, hyphens (-), forward slashes (/), periods (.), and underscores (_).
