However, the IP precedence for
web traffic that conforms to the first rate policy is set to 5. For nonconforming web traffic, the IP
precedence is set to 0 (best effort).
The second rate-limit policy dictates that ICMP traffic be sent with an IP precedence of 0 if it conforms. If
the traffic exceeds the rate policy, it is dropped.
The third rate-limit policy dictates that any remaining traffic is limited to 4 Mbps, with a normal burst size
of 16,000 bytes and an excess burst size of 24,000 bytes. Traffic that conforms is transmitted, and traffic
that does not conform is dropped.
Use the show interfaces
rate-limit command to verify the configuration and monitor CAR
statistics.
Modular QoS CLI (MQC)
Cisco modular QoS command-line interface (CLI), referred to as MQC, provides a modular and highly extensible
framework that allows users to create hierarchical traffic policies to deliver extremely powerful and scalable
solutions. A traffic policy contains a traffic class and one or more QoS features. A traffic class is used to classify
(partition) traffic, whereas the QoS features determine how to treat the classified traffic. With the scalability and
hierarchical policies, MQC can deliver security and attack mitigation solutions that can virtually be used for any
type of attack mitigation.
