Description: Traffic class priority queue the received frame is mapped to.
What is hm2CosMapIpDscpTrafficClass?
This value determines which traffic-class priority queue a frame is assigned to based on its IP DSCP marking, letting the switch translate Layer-3 DSCP values into the switch's internal Layer-2 queue scheme. It is used to keep QoS treatment consistent as traffic crosses from routed, DSCP-marked flows into the switch's local queuing model. For example, an admin might map DSCP value 46, commonly used for voice traffic, to traffic class 7 so that marked voice packets get top-priority queuing on this switch.
