| Summary

This module has outlined the components of Quality of Service and the IOS mechanisms for delivering end-to-end QoS through classification, marking, policing, traffic-shaping and link efficiency mechanisms. Although the general principles for implementing QoS are quite straightforward, there many types of QoS and sometimes several can be used in combination. The accompanying table outlines the supported ingress QoS policies matrix for the Catalyst 3550.
