Properties

Property Type Required Editable Description Constraint
ResourceGroupId String No No The ID of the resource group. None
DeletionProtection Boolean No No Specifies whether to enable deletion protection. Valid values:
  • true
  • false
VpcId String No No The Virtual Private Cloud (VPC) ID of the SLB instance. None
SlaveZoneId String No No The zone ID of the SLB instance. None
Bandwidth Integer No No The maximum bandwidth of the Internet-facing SLB instance that is billed on a pay-by-bandwidth basis.

Valid values: 1 to 10000.

Unit: Mbit/s.

Default value: 1.

Pay-by-traffic is used as the billing method for network usage of VPC-type instances.

  • If the InternetChargeType parameter is set to paybybandwidth, this parameter is valid only when the Bandwidth parameter of the SLB listener is specified.
  • If the InternetChargeType parameter is set to paybytraffic, the Bandwidth parameter of the SLB listener takes precedence and this parameter is ignored.
AddressType String No No The IP address type of the SLB instance.
Default value: internet. Valid values:
  • internet: After an Internet-facing SLB instance is created, the system allocates a public IP address to the instance so that the instance can forward requests from the Internet.
  • intranet: After an internal SLB instance is created, the system allocates an internal IP address to the instance so that the instance can forward only internal requests.
VSwitchId String No No The vSwitch ID of the SLB instance. None
LoadBalancerName String No Yes The name of the SLB instance. The name must be 1 to 80 characters in length and can contain letters, digits, hyphens (-), forward slashes (/), periods (.),and underscores (_).

If this parameter is not specified, the system assigns a value.

InternetChargeType String No No The billing method of the SLB instance for network usage if the instance is connected to the Internet.
Default value: paybytraffic. Valid values:
  • paybybandwidth
  • paybytraffic
MasterZoneId String No No The primary zone ID of the SLB instance. None
Tags List No Yes The tags to be added to the SLB instance. A maximum of five tags can be added.

For more information, see Tags properties.

LoadBalancerSpec String No Yes The instance type of the SLB instance. Default value: slb.s1.small. Valid values:
  • slb.s1.small
  • slb.s2.small
  • slb.s2.medium
  • slb.s3.small
  • slb.s3.medium
  • slb.s3.large
  • slb.s3.xlarge
  • slb.s3.xxlarge

The available instance type varies based on regions. For more information about the instance types, see FAQ about high-performance SLB instances.

PayType String No No The billing method of the SLB instance. Valid values:
  • PayOnDemand
  • PrePay
ModificationProtectionStatus String No No Specifies whether to modify the protection status. Default value: NonProtection. Valid values:
  • NonProtection: The protection status cannot be modified in the console.
  • ConsoleProtection: The protection status can be modified in the console.
ModificationProtectionReason String No No The reason for which the protection status is modified. The reason must be 1 to 80 characters in length and can contain letters, digits, periods (.),and hyphens (-). It must start with a letter.
AddressIPVersion String No No The IP address version of the SLB instance. Valid values:
  • ipv4
  • ipv6
    Note When this parameter is set to ipv6, take note of the supported regions and specifications.

Tags properties

Property Type Required Editable Description Constraint
Key String Yes No The tag key of the SLB instance. The tag key must be 1 to 64 characters in length and cannot contain http:// or https://. It cannot start with acs: or aliyun.
