A system and method to automatically configure packet classification at a customer edge network device connecting a customer network to a service provider network. The method may comprise accessing the IP header of a packet received from the customer network to identify a customer service level classification of the packet. A memory may be accessed to retrieve service provider packet classification data identifying classes of service provided to the customer network. The packet classification of the service provider with the associated customer classification is associated and mapped, whereafter the Ethernet header of the packet may be populated with the mapped service provider packet classification.
