UpdateLoadBalancerAddressTypeConfig - Server Load Balancer

Changes the network type of the IPv4 address for a Network Load Balancer (NLB) instance.

Operation description

Make sure that an NLB instance is created. For more information, see CreateLoadBalancer .
You can call the GetLoadBalancerAttribute operation to query the AddressType value of an NLB instance after you change the network type.
UpdateLoadBalancerAddressTypeConfig is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the GetJobStatus operation to query the task status:
- If the task is in the Succeeded state, the network type of the IPv4 address of the NLB instance is changed.
- If the task is in the Processing state, the network type of the IPv4 address of the NLB instance is being changed. In this case, you can perform only query operations.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

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:
- For mandatory resource types, indicate with a prefix of * .
- 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

Parameter	Type	Required	Description	Example
LoadBalancerId	string	Yes	The ID of the NLB instance.	nlb-83ckzc8d4xlp8o****
AddressType	string	Yes	The new network type. Valid values: Internet: The NLB instance uses a public IP address. The domain name of the NLB instance is resolved to the public IP address. The NLB instance is accessible over the Internet. Intranet: The NLB instance uses a private IP address. The domain name of the NLB instance is resolved to the private IP address. The NLB instance can be accessed over the virtual private cloud (VPC) where the NLB instance is deployed.	Internet
ZoneMappings	array<object>	No	The mappings between zones and vSwitches. You can specify up to 10 zones.
ZoneMapping	object	No	The mapping between the zone and a vSwitch in the zone.
VSwitchId	string	No	The ID of the vSwitch in the zone. You can specify only one vSwitch (subnet) in each zone of an NLB instance.	vsw-bp10ttov87felojcn****
ZoneId	string	No	The zone ID of the NLB instance. You can call the DescribeZones operation to query the most recent zone list.	cn-hangzhou-a
AllocationId	string	No	The ID of the elastic IP address (EIP).	eip-bp1aedxso6u80u0qf****
EipType	string	No	The type of the EIP. Valid values: Common: an EIP Anycast: an Anycast EIP Note This parameter is required only if AddressType is set to Internet.	Common
DryRun	boolean	No	Specifies whether to perform a dry run, without sending 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 (default): performs a dry run and sends the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.	false
ClientToken	string	No	The client token used to ensure the idempotence of the request. You can use the client to generate this value. Ensure that the value is unique among all requests. Only ASCII characters are allowed. Note If you do not specify this parameter, the value of RequestId is used.** RequestId** of each request is different.	123e4567-e89b-12d3-a456-426655440000
RegionId	string	No	The region ID of the NLB instance. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
