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 Resourcesis 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
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| RegionId | string | Yes | The region ID of the QoS policy. You can call the DescribeRegions operation to query the most recent region list. | cn-shanghai |
| ClientToken | string | Yes | The client token that is used to ensure the idempotence of the request. You can use the client to generate a 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 request ID as the client token. The request ID may be different for each request.
| 123e4567-e89b-12d3-a456-426655440000 |
| QosId | string | Yes | The ID of the QoS policy. | qos-2giu0a6vd5x0mv4700 |
| QueueId | string | Yes | The ID of the QoS queue. | qos-queue-9nyx2u7n71s2rcy4n5 |
| Priority | integer | Yes | The priority of the QoS rule. Valid values: 1 to 9000. A larger value indicates a higher priority. The priority of each QoS rule must be unique in the same QoS policy. | 1 |
| Protocol | string | Yes | The protocol of the QoS rule. Valid values:
| ALL |
| SrcCidr | string | No | The source IPv4 CIDR block that matches the QoS rule traffic. Note
When this parameter is unavailable, specify SrcIPv6Cidr or DstIPv6Cidr.
| 1.1.1.0/24 |
| DstCidr | string | No | The destination IPv4 CIDR block that matches the QoS rule traffic. Note
When this parameter is unavailable, specify SrcIPv6Cidr or DstIPv6Cidr.
| 1.1.1.0/24 |
| SrcIPv6Cidr | string | No | The source IPv6 CIDR block that matches the QoS rule traffic. Note
When this parameter is unavailable, specify SrcCidr or DstCidr.
| 2001:0db8:1234:5678::/64 |
| DstIPv6Cidr | string | No | The destination IPv6 CIDR block that matches the QoS rule traffic. Note
When this parameter is unavailable, specify SrcCidr or DstCidr.
| 2001:0db8:1234:5678::/64 |
| SrcPortRange | string | No | The range of source ports that match the QoS rule traffic. Valid values: 0 to 65535. If the traffic does not match, the value is -1. You can specify only one port. The start port number must be the same as the end port number. | -1/-1 |
| DstPortRange | string | No | The range of destination ports that match the QoS rule traffic. Valid values: 0 to 65535. If the traffic does not match, the value is -1. You can specify only one port. The start port number must be the same as the end port number. Different protocols correspond to different ports. Valid values:
| -1/-1 |
| MatchDscp | integer | No | The DSCP value that matches the QoS rule traffic. Valid values: 0 to 63. If no value is matched, the value is -1. | 1 |
| RemarkingDscp | integer | No | The new DSCP value. Valid values: 0 to 63. If you do not change the value, set the value to -1. | 1 |
| RuleName | string | No | The name of the QoS rule. The name must be 0 to 128 characters in length and cannot start with | qos-rule-test |
| RuleDescription | string | No | The description of the QoS rule. The description must be 0 to 256 characters in length and cannot start with | qos-rule-test |

| HTTP status code | Error code | Error message | Description |
|---|---|---|---|
| 400 | IllegalParam.%s | The param of %s is illegal. | The parameter is invalid. |
| 400 | IncorrectStatus.Qos | The status of QoS is incorrect. | The status of the QoS policy is abnormal and the operation cannot be performed. Try again later. |
| 400 | EcQoSConflict | The specified QoS is conflict with other QoS. | The current QoS configuration conflicts with other configurations. Please try again later. |
| 400 | EcQosRuleNotAllowV4AndV6 | QoS rules do not allow IPv4 and IPv6 addresses to be mixed and updated. | Both IPv4 address configuration and IPv6 address configuration are not allowed in a QoS rule. If the original configuration network type is IPv4 and cannot be modified to IPv6 (or vice versa), please check and modify it. |
| 400 | QuotaExceeded.QosRuleCount | The quota of QosRuleCount is exceeded. | The number of QoS rules in the QoS queue exceeds the limit. If you want to increase the quota, contact your business manager. |
