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. Default value: false. Valid values:
  • true: enables deletion protection.
  • false: does not enable deletion protection.
VpcId String No No The ID of the virtual private cloud (VPC). 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 supports the pay-by-bandwidth metering method.

Valid values: 1 to 10000.

Unit: Mbit/s.

Default value: 1.

The maximum bandwidth of an internal-facing SLB instance is set by the system when you configure the pay-by-data-transfer metering method for the instance.

  • If the InternetChargeType property is set to paybybandwidth, the Bandwidth property only takes effect when the Bandwidth value of the SLB listener is set.
  • If the InternetChargeType property is set to paybytraffic, the Bandwidth value that you set for the SLB listener takes precedence over the value of the Bandwidth property.
AddressType String No No The IP address type of the SLB instance.
Default value: internet. Valid values:
  • internet: The SLB instance uses a public IP address. The domain name of the instance is resolved to the public IP address. Therefore, the instance can be accessed over the Internet.
  • intranet: The SLB instance uses a private IP address. The domain name of the instance is resolved to the private IP address. Therefore, the SLB instance can be accessed only over the VPC in which the instance is deployed.
VSwitchId String No No The ID of the vSwitch. 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 you do not specify this property, the system assigns a name as the value of this property.

InternetChargeType String No No The metering method of the Internet-facing SLB instance.
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 that you want to add to the SLB instance. You can add up to five tags.

For more information, see Tags properties.

LoadBalancerSpec String No Yes The specification 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 specification of an SLB instance varies based on the region in which the SLB instance is deployed. For more information about each instance specification, see FAQ about high-performance SLB instances.

PayType String No No The billing method of the SLB instance. Valid values:
  • PayOnDemand: the pay-as-you-go billing method
  • PrePay: the subscription billing method
ModificationProtectionStatus String No No Specifies whether to enable the configuration read-only mode. Default value: NonProtection. Valid values:
  • NonProtection: disables the configuration read-only mode.
  • ConsoleProtection: enables the configuration read-only mode. You can enable this mode in the SLB console.
ModificationProtectionReason String No No The reason why you want to enable the configuration read-only mode. The reason must be 1 to 80 characters in length, and can contain letters, digits, periods (.), and hyphens (-).
AddressIPVersion String No No The version of the IP address. Valid values:
  • ipv4
  • ipv6
    Note When you set the value to ipv6, take note of the available regions and specifications.
AutoRenewPeriod Integer No No The auto-renewal cycle of the SLB instance. This property only takes effect when the AutoRenew property is set to true.

  • Valid values if the PricingCycle property is set to Month: 1 to 9.
  • Valid values if the PricingCycle property is set to Year: 1 to 3.
AutoRenew Boolean No No Specifies whether to enable auto-renewal for the SLB instance. Default value: false. Valid values:
  • true: enables auto-renewal.
  • false: does not enable auto-renewal.

Tags syntax

"Tags": [
  {
    "Key": String,
    "Value": String 
  }
]

Tags property

Field Type Required Editable Description Constraint
Key String Yes No The key of the tag. The key must be 1 to 64 characters in length, and cannot contain http:// or https://. It cannot start with acs: or aliyun.
Value String No No The value of the tag. The value must be 0 to 128 characters in length, and cannot contain http:// or https://. It cannot start with acs: or aliyun.
