QoS in MC-MLPPP
Quality of Service Guide 837
Table 71 and Figure 53 provide the details of the class queue threshold parameters. Packets
that are marked with high drop precedence, for example, out-of-profile, by the service or
network ingress QoS policy will be discarded when any class queue reaches the OOP
threshold. Packets with a low drop precedence marking, for example, in profile, will be
discarded when any class queue reaches the max threshold. Only the max threshold is user
configurable and is referred to as max-queue-size in the CLI. The OOP threshold is always
set to 50% of the max threshold.
