Configuring Quality of Service
This chapter describes the quality of service (QoS) features built into your ML-Series card and how to
map QoS scheduling at both the system and interface levels.

The ML-Series card employs the Cisco IOS Modular QoS command-line interface (CLI), known as the
MQC. For more information on general MQC configuration, refer to the following Cisco IOS

Understanding QoS
QoS is the ability of the network to provide better or special treatment to a set of services to the detriment
of less critical services. The ML-Series card uses QoS to dynamically allocate transmission bandwidth
for the different services it multiplexes onto the SONET/SDH circuit. Through QoS, you can configure
