Port Features
QoS in MC-MLPPP
If the user enables the multiclass option under an MLPPP bundle, the MDA egress data path
provides a queue for each of the 4 classes of MLPPP. The user configures the required number of
MLPPP classes to use on a bundle. The forwarding class of the packet, as determined by the
ingress QoS classification, is used to determine the MLPPP class for the packet and hence which
of the four egress MDA queues to store the packet. The mapping of forwarding class to MLPPP
class is a function of the user configurable number of MLPPP classes. The default mapping for a
4-class, 3-class, and 2-class MLPPP bundle is shown in
