CHAPTER 15 QoS 15.1 Overview This chapter introduces the quality of service (QoS) parameters you can configure on the Switch. QoS is used to help solve performance degradation when there is network congestion. The Switch allows you to use IEEE 802.1p priority tags or Differentiated Services Code Points (DSCPs) tags to prioritize traffic. 15.2 What You Can Do • Use the Port Priority screen (Section 15.4 on page 86) to specify IEEE 802.1p priority for each port. • Use the IP DiffServ (DSCP) screen (Section 15.5 on page 87) to configure DSCP-based QoS settings. • Use the Priority/Queue Mapping screen (Section 15.6 on page 89) to configure IEEE 802.1p priority and queue mappings for the Switch. • Use the Queuing Method screen (Section 15.7 on page 90) to configure the weight value of each queue. 15.3 What You Need to Know 15.3.1 Queuing algorithms Queuing algorithms allow switches to maintain separate queues for packets from each individual source or flow and prevent a source from monopolizing the bandwidth.
