Operation Manual – QoS-QoS ProfileH3C S3100 Series Ethernet Switches Chapter 1 QoS Configuration1-3adjusting traffic. Congestion avoidance is usually applied in the outbound directionof a port.Traffic classification is the basis of all the above-mentioned traffic managementtechnologies. It identifies packets using certain rules and makes differentiated servicespossible. Traffic policing, traffic shaping, congestion management, and congestionavoidance are methods for implementing network traffic control and network resourcemanagement. They are occurrences of differentiated services.1.2 QoS Supported by the S3100 Series Ethernet SwitchesThe S3100 series Ethernet switches support the QoS features listed in Table 1-1.Table 1-1 QoS features supported by the S3100 series Ethernet switchesCategory Features Refer to…Traffic classificationIncoming traffic classificationbased on ACLs of thefollowing types:z Basic ACLsz Advanced ACLsz Layer-2 ACLsz For detailedinformation aboutACLs, refer to theACL module inthis manual.z For informationabout trafficclassification,refer to TrafficClassification.QoS actionQoS actions for packetsmatching the specified ACL:z Priority markingz Traffic policingz Traffic redirectingz Traffic accountingz Traffic mirroringz For informationabout prioritymarking, refer toPriority Marking.z For informationabout trafficpolicing, refer toTraffic Policingand TrafficShaping.z For informationabout trafficredirecting, referto TrafficRedirecting.z For informationabout trafficaccounting, referto Flow-BasedTrafficAccounting.z For informationabout trafficmirroring, refer toTraffic Mirroring.
