Guidelines for Configuring CoS for Subscriber Access

When configuring CoS for subscriber access, consider the following guidelines:

In the current release, you configure the traffic scheduling and shaping parameters in a traffic-control profile within the dynamic profile. You can configure the scheduler map and schedulers in a dynamic profile or in the [edit class-of-service] hierarchy. You must statically configure the remaining CoS parameters, such as hierarchical scheduling, classifiers, drop profiles, and forwarding classes, in the [edit class-of-service] hierarchy.
You must enable hierarchical scheduling in the static CLI for the interface referenced in the dynamic profile. If not, the dynamic profile fails.
You can configure only one traffic-control-profile under a dynamic profile.
You must define the output-traffic-control-profile that binds the traffic-control profile to the interface within the same dynamic profile as the interface.
We recommend that you provide different names for the schedulers defined in dynamic profiles that are used for access and services. For example, if there are two dynamic profiles, voice-profile and video-profile, provide unique names for the schedulers defined under those profiles.
