A UAFX Station shall provide a PriorityMappingTable with at least the default entries for MappingUri/QosCate gory and PriorityLabel as defined in Table 3. If PCP and DSCP values have not been explicitly configured (i.e., to accommodate the needs of an existing network), PriorityValue_PCP and PriorityValue_DSCP shall assume the values defined in Table 3.

Table 3 – Default PriorityMappingEntryType values

MappingUri/QosCategory	PriorityLabel	PriorityValue_PCP(default)	PriorityValue_DSCP(default)
opc.qos.cat://priority	opc.qos.lbl://green	4	46

Each physical network interface available to the UAFX Application represented by an instance of IetfBaseNetworkInterfaceType in the NetworkInterfaces Folder shall have a reference to an instance of PriorityMappingTableType that is exposed to OPC UA Clients, e.g., for adaptation during the system integration phase (see 5.6.4.4), as defined in OPC 1000022. The referenced PriorityMappingTableType instance shall include the AddPriorityMappingEntry and DeletePriorityMappingEntry Methods.
