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
RegionId	string	No	The ID of the region where the network instance is located. You can call the DescribeChildInstanceRegions operation to query region IDs.	cn-hangzhou
CenId	string	Yes	The ID of the CEN instance.	cen-nye53d7p3hzyu4****
ProductType	string	Yes	The type of the network instance. Valid values: VPC: a virtual private cloud (VPC). VBR: a virtual border router (VBR). CCN: a Cloud Connect Network (CCN) instance. VPN: an IPsec-VPN connection. ECR: an Express Connect router.	VPC
MaxResults	integer	No	If you omit this parameter, all entries are returned. The MaxResults value in the response then indicates the total number of entries. If you set this parameter, the response is paginated. The MaxResults value specifies the number of entries to return on each page. Valid values: 1 to 100. The MaxResults value in the response indicates the number of entries on the current page. Setting MaxResults to 20 is recommended.	20
NextToken	string	No	The token used to retrieve the next page of results. Omit this parameter for the first request. Set this parameter to the NextToken value from the previous response to retrieve the next page of results.	FFmyTO70tTpLG6I3FmYAXGKPd****
ChildInstanceId	string	No	The ID of the network instance to query.	vpc-rj9gt5nll27onu7****
ChildInstanceOwnerId	integer	No	The ID of the Alibaba Cloud account that owns the network instance.	1250123456123456
EnabledIpv6	boolean	No	Specifies whether IPv6 is enabled. This parameter applies only when ProductType is set to VPC. Set to true to return only VPCs with IPv6 enabled, or false to return only those with IPv6 disabled. If you omit this parameter, the response is not filtered by the IPv6 status.	true
