ReplaceVpcDhcpOptionsSet - Virtual Private Cloud - Alibaba Cloud Documentation Center

Replaces the DHCP options set that is associated with a virtual private cloud (VPC).

Operation description

The ReplaceVpcDhcpOptionsSet operation is asynchronous. After you send the request, the system returns a request ID. However, the operation is still being performed in the system background. You can call the DescribeVpcAttribute operation to query the status of a DHCP options set:
- If the DHCP options set is in the Pending state, the DHCP options set is being replaced.
- If the DHCP options set is in the InUse state, the DHCP options set is replaced.
You cannot repeatedly call the ReplaceVpcDhcpOptionsSet operation to replace the DHCP options set associated with a VPC within the specified period of time.

There is currently no authorization information disclosed in the API.

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region to which the DHCP options set belongs. You can call the DescribeRegions operation to query the most recent region list.	cn-hangzhou
DhcpOptionsSetId	string	Yes	The ID of the new DHCP options set.	dopt-o6w0df4epg9zo8isy****
VpcId	string	Yes	The ID of the associated VPC.	vpc-dsferghthth****
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The client token can contain only ASCII characters. Note If you do not set this parameter, the system uses RequestId as ClientToken. RequestId may be different for each API request.	0c593ea1-3bea-11e9-b96b-88e9fe637760
DryRun	boolean	No	Specifies whether to check the request without performing the operation. Valid values: true: checks the request without performing the operation. The system checks whether your AccessKey pair is valid, whether the Resource Access Management (RAM) user is authorized, and whether the required parameters are set. If the request fails to pass the check, the corresponding error message is returned. If the request passes the check, the DryRunOperation error code is returned. false (default): sends the request. If the request passes the check, a 2XX HTTP status code is returned and the operation is performed.	false
