Virtual Private Cloud:ReplaceVpcDhcpOptionsSet

Last Updated:May 14, 2024

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.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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


The region to which the DHCP options set belongs. You can call the DescribeRegions operation to query the most recent region list.


The ID of the new DHCP options set.


The ID of the associated VPC.


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.

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.

Response parameters


The ID of the request.
