DSCP is a mechanism used for classifying network traffic on IP networks It uses the 6 bit Dif ferentiated Services Field DS or DSCP field in the IP header for packet classification purposes Using Layer 3 classification enables you to maintain the same classification semantics beyond local network across routers Every transmitted packet holds the information allowing network devices to map the packet to the appropriate 802 1Qbb CoS For DSCP based PFC the packet is marked with a DSCP value in the Differentiated Services DS field of the IP header 3 1 10 1 Setting the DSCP in the IP Header Marking DSCP value in the IP header is done differently for IP packets constructed by the NIC e g RDMA traffic and for packets constructed by the IP stack e g TCP traffic ForIP packets generated by the IP stack the DSCP value is provided by the IP stack The NIC does not validate the match between DSCP and Class of Service CoS values CoS and DSCP values are expected to be set through standard tools such as PowerShell command New NetQosPolicy using Priority Value8021Action and DSCPAction flags respectively For IP packets generated by the NIC RDMA the DSCP value is generated according to the CoS value programmed for the interface CoS value is set through standard tools such as PowerShell command New NetQosPolicy using Priority Value8021 Action flag The NIC uses a mapping table between the CoS value and the DSCP value configured thr
