Virtual Private Cloud:UnassociateRouteTable

Last Updated:Dec 02, 2023

Disassociates a route table from a vSwitch.

Operation Description


  • UnassociateRouteTable 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 DescribeVSwitchAttributes operation to query the status of the task.

    • If the vSwitch is in the Pending state, the route table is being disassociated.
    • If the vSwitch is in the Available state, the route table is disassociated.
  • You cannot repeatedly call the UnassociateRouteTable operation to disassociate a route table from a vSwitch within the specified period of time.


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


The region ID of the virtual private cloud (VPC) to which the custom route table belongs.

You can call the DescribeRegions operation to query the most recent region list.


The ID of the route table.


The ID of the vSwitch from which you want to disassociate the route table.


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 specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

Response parameters


The request ID.
