Cloud Enterprise Network:CreateCenInterRegionTrafficQosQueue

Last Updated:Aug 12, 2026

Creates a queue configuration under a traffic scheduling policy. If you need to manage different types and priorities of network traffic to ensure the performance of critical service traffic and comply with Service-Level Agreements (SLAs), you can call the CreateCenInterRegionTrafficQosQueue operation.

Operation description

CreateCenInterRegionTrafficQosQueue is an asynchronous operation. After you send a request, the system returns a queue ID but the queue is not yet created. The creation task continues to run in the background. You can call the ListCenInterRegionTrafficQosPolicies operation to query the status of the traffic scheduling policy to determine the creation status of the queue. When you call this operation, you must specify the TrafficQosPolicyId parameter.

  • If the traffic scheduling policy is in the Modifying state, the queue is being created. In this state, you can only query the traffic scheduling policy and queue. You cannot perform other operations.

  • If the traffic scheduling policy is in the Active state, the queue is created.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter

Type

Required

Description

Example

ClientToken

string

No

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 RequestId value as the ClientToken value. The RequestId value of each API request is different.

123e4567-e89b-12d3-a456-426****

DryRun

boolean

No

Specifies whether to perform a dry run. 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. If the request passes the dry run, the queue is created.

false

QosQueueName

string

No

The name of the queue.

The name can be empty or 1 to 128 characters in length and cannot start with http:// or https://.

nametest

QosQueueDescription

string

No

The description of the queue.

The description can be empty or 1 to 256 characters in length and cannot start with http:// or https://.

desctest

RemainBandwidthPercent

string

No

The maximum inter-region bandwidth that the queue can use when bandwidth is allocated by percentage.

  • The bandwidth value is calculated as a percentage. For example, if you enter 20, the queue can use up to 20% of the inter-region bandwidth.

  • The sum of the bandwidth percentages of all queues under an inter-region connection cannot exceed 100%.

20

Bandwidth

integer

No

The maximum inter-region bandwidth that the queue can use when bandwidth is allocated by absolute value. Unit: Mbit/s.

  • The bandwidth value is calculated as an absolute value. For example, if you enter 20, the queue can use up to 20 Mbit/s of inter-region bandwidth.

  • The sum of the bandwidth values of all queues under an inter-region connection cannot exceed the inter-region bandwidth value.

20

TrafficQosPolicyId

string

Yes

The ID of the traffic scheduling policy.

qos-qdvybn468kaoxx****

Dscps

array

Yes

The DSCP values to be matched by the queue.

You can specify up to 20 DSCP values at a time. Separate multiple DSCP values with commas (,).

integer

No

The DSCP values to be matched by the queue.

You can specify up to 20 DSCP values at a time. Separate multiple DSCP values with commas (,).
