属性

属性名称 类型 必须 允许更新 描述 约束
MinBandwidthAbs Integer 否 是 最小带宽。 当LimitType取值为Absolute时，必须指定该参数。
Description String 否 是 QoS限速规则的描述。 无
MaxBandwidthPercent Integer 否 是 最大带宽百分比。 当LimitType取值为Percent时，必须指定该参数。
Priority Integer 是 是 规则的优先级。 取值范围：1~7。

取值越小，优先级越高。
MaxBandwidthAbs Integer 否 是 最大带宽。 当LimitType取值为Absolute时，必须指定该参数。
QosId String 是 否 QoS策略的实例ID。 关于QoS策略的更多信息，请参见什么是QoS策略。
PercentSourceType String 否 是 按百分比限速时的带宽类型。 取值：
  • CcnBandwidth：云连接网带宽。
  • InternetUpBandwidth：公网上行带宽。
MinBandwidthPercent Integer 否 是 最小带宽百分比。 当LimitType取值为Percent时，必须指定该参数。
LimitType String 是 是 限速类型。 取值：
  • Absolute：按带宽值。
  • Percent：按百分比。
Name String 否 是 QoS限速规则名称。 长度为2~128个字符，以英文字母或汉字开头，可包含英文字母、汉字、数字、半角句号（.）、下划线（_）和短划线（-）。
