QoS

Consider the following when configuring QoS:

  • Understand your network traffic patterns and requirement. You might have to observe the QoS class statistics,and change queue depths, and/or change the default QoS class share percentage to avoid tail-drops as shown in QoS statistics.
  • Sometimes, the entire subnet is added to a Rule for ease of configuration instead of creating Rules for particular application IP addresses. Adding entire subnet to a rule incorrectly maps all the traffic in the subnet to one Rule. Therefore the QoS classes associated with that Rule might lead to tail drop and poor application performance or user experience.
