UpdateTransitRouterVpcAttachmentZones - Cloud Enterprise Network

Modifies the zones and vSwitches that are associated with a virtual private cloud (VPC) connection.

Operation description

When you add a zone and a vSwitch for a VPC connection, make sure that the vSwitch has at least one idle IP address. When you modify the zones and vSwitches of a VPC connection, the Enterprise Edition transit router creates an elastic network interface (ENI) in the vSwitch. The ENI occupies one IP address in the vSwitch. The ENI forwards traffic between the VPC and the Enterprise Edition transit router.
UpdateTransitRouterVpcAttachmentZones is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the ListTransitRouterVpcAttachments operation to query the status of a VPC connection.
- If a VPC connection is in the Modifying state, the VPC connection is being modified. You can query the VPC connection but cannot perform other operations.
- If a VPC connection is in the Attached state, the VPC connection is modified.

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:
- The required resource types are displayed in bold characters.
- 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
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters. Note If you do not set this parameter, ClientToken is set to the value of RequestId. The value of RequestId for each API request may be different.	123e4567-e89b-12d3-a456-42665544****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run. The system checks the required parameters, request syntax, and 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 request.	false
TransitRouterAttachmentId	string	Yes	The ID of the VPC connection.	tr-attach-9bbqyygouv4cpn****
AddZoneMappings	array<object>	No	The zones and vSwitches that you want to add to the VPC connection.
	object	No	The ID of the vSwitch that you want to add to the VPC connection. You can specify at most 10 vSwitches in each call.
VSwitchId	string	No	The ID of the vSwitch that you want to add to the VPC connection. You can specify at most 10 vSwitches in each call. If the VPC connection belongs to the current Alibaba Cloud account, you can call the DescribeVSwitches operation to query the IDs of the vSwitches and zones of the VPC. If the VPC connection belongs to another Alibaba Cloud account, you can call the ListGrantVSwitchesToCen operation to query the IDs of the vSwitches and zones of the VPC.	vsw-wz988dda8ldm4uvmx****
ZoneId	string	No	The ID of the zone where the vSwitch that you want to add to the VPC connection is deployed. You can specify at most 10 vSwitches in each call.	cn-hangzhou-h
RemoveZoneMappings	array<object>	No	The zones and vSwitches that you want to remove from the VPC connection.
	object	No	The zones and vSwitches that you want to remove from the VPC connection. You can specify at most 10 pairs of zones and vSwitches in each call.
VSwitchId	string	No	The ID of the vSwitch that you want to remove from the VPC connection. You can remove at most 10 vSwitches from a VPC in each call.	vsw-wz9f5izl6wshndmta****
ZoneId	string	No	The ID of the zone where the vSwitch that you want to remove from the VPC connection is deployed.	cn-hangzhou-i
