Configuring a QoS policy
In this chapter, "MSR2000" refers to MSR2003. "MSR3000" collectively refers to MSR3012, MSR3024,
MSR3044, MSR3064. "MSR4000" collectively refers to MSR4060 and MSR4080.
You can configure QoS by using the MQC approach or non-MQC approach. Some features support
both approaches, but some support only one.
Non-MQC approach
In the non-MQC approach, you configure QoS service parameters without using a QoS policy. For
example, you can use the rate limit feature to set a rate limit on an interface without using a QoS policy.
MQC approach
In the modular QoS configuration (MQC) approach, you configure QoS service parameters by using
QoS policies. A QoS policy defines the shaping, policing, or other QoS actions to take on different
classes of traffic. It is a set of class-behavior associations.
A traffic class is a set of match criteria for identifying traffic, and it uses the AND or OR operator:
• If the operator is AND, a packet must match all the criteria to match the traffic class.
• If the operator is OR, a packet matches the traffic class if it matches any of the criteria in the traffic
class.
A traffic behavior defines a set of QoS actions to take on packets, such as priority marking and redirect.
By associating a traffic behavior with a traffic class in a QoS policy, you apply the specific set of QoS
actions to the traffic class.
