我不熟悉 2960XR 的语法。在将 Cisco 9300 上当前的 QoS 配置与 cisco 2960XR 匹配时，我需要帮助。谢谢你。QoS 配置是 HQoS 并且如下：

BRS-TC-SW-01#show policy-map
    Policy Map CHILD
    Class COS_Q3
          priority level 1
          police rate percent 20

          exceed-action drop
    Class COS_Q2
          bandwidth remaining 57 (%)
    Class COS_Q1
          bandwidth remaining 29 (%)
    Class COS_Q0
          bandwidth remaining 14 (%)
