Cloud Enterprise Network:DeleteCenInterRegionTrafficQosPolicy

Last Updated:Mar 25, 2024

Deletes a quality of service (QoS) policy.

Operation description

  • Before you delete a QoS policy, you must delete all queues in the QoS policy except the default queue. For more information, see DeleteCenInterRegionTrafficQosQueue .

  • DeleteCenInterRegionTrafficQosPolicy 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 ListCenInterRegionTrafficQosPolicies operation to query the status of a QoS policy.

    • If a QoS policy is in the Deleting state, the QoS policy is being deleted. You can query the QoS policy but cannot perform other operations.
    • If a QoS policy cannot be found, the QoS policy is deleted.


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

You can use the client to generate the value, but you must make sure that it is unique among all requests. The client 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.

Specifies whether to perform a dry run. Default value: false. 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.
