Cloud Enterprise Network:CreateCenInterRegionTrafficQosQueue

Last Updated:Apr 11, 2023

Creates a queue in a quality of service (QoS) policy.

Operation Description

The CreateCenInterRegionTrafficQosQueue operation 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 the QoS policy to determine the status of the queue. When you call this operation, you must set the TrafficQosPolicyId parameter.

  • If a QoS policy is in the Modifying state, the queue is being created. In this case, you can query the QoS policy and queue but cannot perform other operations.
  • If a QoS policy is in the Active state, the queue is created.

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 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 all requests. The token can contain only ASCII characters.

NoteIf you do not set this parameter, ClientToken is set to the value of RequestId. The value of RequestId may be different for each request.

Specifies whether to perform a dry run. Valid values:

  • true: performs a dry run. The system checks the required parameters, the request format, and the service 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.

The name of the queue.

The name must be 2 to 128 characters in length, and can contain letters, digits, hyphens (-), and underscores (_). It must start with a letter.


The description of the queue.

The description must be 1 to 256 characters in length, and can contain letters, digits, underscores (_), and hyphens (-). It must start with a letter.


The maximum bandwidth of the queue,

  • in percentage. For example, a value of 20 specifies that the queue can occupy at most 20% of the bandwidth allocated to the inter-region connection.
  • The sum of percentage values specified for all queues that belong to the same inter-region connection cannot exceed 100%.

The ID of the QoS policy.


The differentiated services code point (DSCP) value that matches the current queue.

You can specify at most 20 DSCP values for a queue in each call. Separate DSCP values with commas (,).


The DSCP value that matches the current queue.

You can specify at most 20 DSCP values for a queue in each call. Separate DSCP values with commas (,).


Response parameters


The response.


The ID of the queue.

Error codes

HTTP status codeError codeError messageDescription
400IllegalParam.RemainBandwidthPercentThe specified RemainBandwidthPercent is invalid.The error message returned because the RemainBandwidthPercent parameter is set to invalid value.
400IncorrectStatus.TrafficQosPolicyThe status of TrafficQosPolicy is incorrect.The error message returned because the status of the specified QoS policy does not support the operation.
400Duplicated.DscpsThe parameter Dscps are duplicated.The error message returned because the descriptions are duplicate.
404InvalidTrafficQosPolicyId.NotFoundThe specified TrafficQosPolicyId is not found.The error message returned because the specified QoS policy ID (TrafficQosPolicyId) does not exist.
