# Class CIM_Hdr8021PService
extends CIM_QoSService

This class represents a specialization of the general concept of forwarding network traffic by adding specific semantics that define how traffic is forwarded based on the value of the Priority field in the 802.1P header. This class is used to enable DiffServ domains and domains that support 802.1P only to exchange traffic. It represents the mapping between implementations that only support 802.1P priority marking to be mapped to implementations that support DiffServ, which use DSCPs. Hdr8021PService is deprecated since forwarding based on the value of the Priority field in the 802.1P header is specified using a FilterList, which is associated with a ClassifierElement. If there is a need to distinguish a higher-level set of coordinated QoS services, the QoSService class can be instantiated directly.
