Call CreateCenInterRegionTrafficQosQueue to create a QoS queue - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Creates a queue configuration for a traffic scheduling policy. You can invoke the CreateCenInterRegionTrafficQosQueue operation to manage network traffic of different types and priorities in a fine-grained manner, ensuring the performance of critical service traffic and compliance with the service level protocol.

Operation description

The CreateCenInterRegionTrafficQosQueue operation is asynchronous. The system first returns a queue ID, but the queue is not yet created and the creation task is still running in the background. You can call the ListCenInterRegionTrafficQosPolicies operation to query the status of the traffic scheduling policy and determine the creation status of the queue. When you query the status, 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 perform query operations on the traffic scheduling policy and the queue. You cannot perform other operations.
If the traffic scheduling policy is in the Active state, the queue is created.

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 generate a parameter value on your client to ensure that the value is unique across different requests. The client token only supports ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the client token. The RequestId of each API request may be different.	123e4567-e89b-12d3-a456-426****
DryRun	boolean	No	Specifies whether to only precheck the request. Valid values: true: sends a check request and does not create the queue. The system checks whether required parameters are specified, the request format is valid, and service limits are met. If the request fails the check, the system returns an error. If the request passes the check, the system returns the `DryRunOperation` error code. false (default): sends a regular request and creates the queue after the request passes the check.	false
QosQueueName	string	No	The name of the queue. The name can be empty or 1 to 128 characters in length. It 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. It cannot start with http:// or https://.	desctest
RemainBandwidthPercent	string	No	The maximum cross-region bandwidth that the queue can use when bandwidth is allocated in percentage mode. The bandwidth value is calculated as a percentage. For example, if you enter 20, the queue can use up to 20% of the cross-region bandwidth. The sum of the bandwidth percentages of all queues under a cross-region connection instance cannot exceed 100%.	20
Bandwidth	integer	No	The maximum cross-region bandwidth that the queue can use when bandwidth is allocated in absolute value mode. 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 the cross-region bandwidth. The sum of the bandwidth of all queues under a cross-region connection instance cannot exceed the cross-region bandwidth.	20
TrafficQosPolicyId	string	Yes	The ID of the traffic scheduling policy.	qos-qdvybn468kaoxx****
Dscps	array	Yes	The Differentiated Services Code Point (DSCP) values to be matched by the queue. You can enter up to 20 DSCP values at a time. Separate multiple DSCP values with commas (,).
	integer	No	The Differentiated Services Code Point (DSCP) values to be matched by the queue. You can enter up to 20 DSCP values at a time. Separate multiple DSCP values with commas (,).	5
