Queries the information about quality of service (QoS) policies.
Operation description
When you call the ListCenInterRegionTrafficQosPolicies operation, take note of the following information:
-
If you do not set the TrafficQosPolicyId parameter, the system returns information about QoS policies based on the values of the TransitRouterId, TransitRouterAttachmentId, TrafficQosPolicyName, and TrafficQosPolicyDescription parameters, but does not return information about the queues in the QoS policies. The TrafficQosQueues parameter is not included in the response.
-
If you specify a QoS policy ID in the TrafficMarkingPolicyId parameter, the system returns the information about the QoS policy and the queues. The TrafficQosQueues parameter is included in the response.
If the TrafficQosQueues parameter contains an empty array, it indicates that the QoS policy contains only the default queue.
