Last Updated:May 14, 2024

Disassociates a DHCP options set from a virtual private cloud (VPC).

Operation description


  • DetachDhcpOptionsSetFromVpc is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeVpcAttribute operation to query the status of the task.

    • If the DHCP options set is in the Pending state, the DHCP options set is being disassociated.
    • If the DHCP options set is in the UnUsed state, the DHCP options set is disassociated.
  • You cannot repeatedly call the DetachDhcpOptionsSetFromVpc operation to disassociate a DHCP options set from 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.

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 DHCP options set to be disassociated from a VPC.


The ID of the VPC.


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 client token can contain only ASCII characters.

Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

Specifies whether to perform only a dry run, without performing the actual request. Valid values:

true: performs only a dry run. The system checks your AccessKey pair, the Resource Access Management (RAM) user permissions, and the required parameters. 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 performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.
