The MLPPP class queue parameters and its scheduling parameters are also configured by applying
one of the three pre-defined egress QoS profiles to an MLPPP bundle.
Table 11 and Figure 9 provide the details of the class queue threshold parameters. Packets marked
with a high drop precedence, such as out-of-profile, by the service or network ingress QoS policy
will be discarded when any class queue reaches the OOP threshold. Packet with a low drop
precedence marking, such as in-profile, will be discarded when any class queue reaches the max
threshold.
