  20. 802.1p bit mapping to QoS • Tagged Ethernet frames have a priority of 0-7 • By default, tags are not passed to the ELAN (P/Q support disabled) • The LEC signals for the default SVC type (UBR) unless configured otherwise • Priority information is lost when frames are transferred back to the VLAN at the far end • QoS bundles allow priority information to be preserved by mapping an 802.1p bit to a specific SVC type • A QoS bundle consists of up to eight QoS sets • Each QoS set maps an 802.1p priority to an existing UPC contract • A QoS bundle is associated with a LEC using the –qosIndex parameter
