Campus Distribution (Cisco Catalyst 4500) QoS Design

Chapter Description

This chapter discusses the best-practice QoS design recommendations for the Cisco Catalyst 4500 (Supervisor 6-E/7-E) series switch in the role of a campus distribution layer switch.

QoS Design Steps

While there are two explicit QoS policy requirements of a distribution switch (namely to trust DSCP on ingress and queuing policies), because of the default QoS settings on MQC-based platforms there is effectively only a single step to configuring QoS on a Catalyst 4500 in this role:

  1. Configure the ingress QoS model—which is recommended to be DSCP trust (and which is enabled by default on all MQC-based platforms).

  2. Configure egress queuing.
3. Queuing Models | Next Section Previous Section
