In This Section
This section provides information to configure MC-MLPPP using the command line
interface.
Topics in this section include:
Overview
If the user enables the multiclass option under an MLPPP bundle, the XMA or 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 XMA or 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
