A network device includes a packet ingress configured to receive packets from a network, and a packet processor. The packet processor is configured to identify a first packet of the received packets as a double VLAN tagged packet including a first priority field associated with a first VLAN tag and a second priority field associated with a second VLAN tag. The packet processor is also configured to assign an extended priority profile to the first packet based on one or more bits of the first priority field and one or more bits of the second priority field, the extended priority profile being among a group of possible extended priority profiles that is larger than any group of possible priority profiles associated with a single VLAN tag of the first packet. The packet processor is further configured to process the first packet according to the assigned extended priority profile.
