Operation description

QPS limits

This API is limited to 10 queries per second (QPS) for each user. If you exceed this limit, API calls are throttled, which may affect your business. Call this API at a reasonable rate to prevent throttling.

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
DdosRegionId	string	Yes	The ID of the region where the asset that is assigned a public IP address resides. Note Call DescribeRegions to query all region IDs.	cn-hangzhou
InstanceType	string	Yes	The instance type of the asset that is assigned a public IP address. Valid values: ecs: an Elastic Compute Service (ECS) instance. slb: a Server Load Balancer (SLB) instance. eip: an Elastic IP Address (EIP) instance. ipv6: an IPv6 Gateway instance. swas: a simple application server instance. waf: a dedicated Web Application Firewall (WAF) instance. ga_basic: a Global Accelerator (GA) instance.	ecs
InstanceId	string	Yes	The instance ID of the asset that is assigned a public IP address. Note Call DescribeInstance to query the IDs of the ECS, SLB, and EIP instances that belong to your Alibaba Cloud account.	i-uf6idy3c57psf7vu****
Bps	integer	No	The traffic scrubbing threshold in Mbps. This threshold cannot exceed the peak public network traffic of the instance. If you set this parameter, you must also set the Pps parameter. Otherwise, the configuration does not take effect. Use the monitoring tools that are provided for your instance to query its public network traffic: If you use an ECS instance, see View instance monitoring data. If you use an SLB instance, see View monitoring data.	100
Pps	integer	No	The packet scrubbing threshold in packets per second (pps). If you set this parameter, you must also set the Bps parameter. Otherwise, the configuration does not take effect. This threshold cannot exceed the peak data packet traffic of the instance. Use the monitoring tools that are provided for your instance to query its data packet traffic: If you use an ECS instance, see View instance monitoring data. If you use an SLB instance, see View monitoring data.	70000
IsAuto	boolean	No	Specifies whether to automatically adjust the scrubbing threshold based on the traffic load of the instance. Valid values: true: The scrubbing threshold is automatically adjusted. You do not need to set the Bps and Pps parameters. false: The scrubbing threshold is not automatically adjusted. You must set the Bps and Pps parameters. Default value: false	false
InternetIp	string	No	The public IP address of the asset.	192.0.XX.XX
ClientToken	string	No
